Golf IV / Jetta IV :: Radiator Hose Gets Really Hot At Normal Temp?
yesterday my upper radiator hose connector broke off and I replaced it filled it up with coolant and now the upper radiator hose gets really hot at normal temps while the lower hose is cold maybe and gets warm not hot or anything... I see some steam coming off the radiator but i think its all the coolant that splashed on it yesterday from the hose busting off and flooding it basically. the car does not overheat at idle or driving or anything so I am curious to what it could be
View 4 RepliesGolf IV / Jetta IV :: Coolant Temp Light Came Flashing On - Oil Getting Into Coolant
Okay so recently I was driving my 2000 Jetta and the coolant temp light came flashing on, when I went to check the coolant I was surprised to discover that it was like a mud brown color, almost looks like peanut butter. From everything I have read this can be from a few things, either rust build up that is gunking everything up and oil getting into the coolant somehow. I'm pretty sure its rust build up but I was wondering what everyone thinks about this, I was also not using G12 coolant which I'm told now is the premier brand for VW's.

So my check engine light came on in my 04 jetta sw, and when I had the car read, it gave me a code that tracked down to be a bad coolant temp sensor. I bought the replacement part from my local VW dealership, installed it and the check engine light went away. Now about 2 weeks late it came back on, and I am getting a reading of "Coolant temp sensor high voltage". So it goes from needing replaced, then the replacement is running high voltage?

Today was the first time my wagon has stranded me due to a mechanical issue. During city driving my coolant temp light came on so I pulled over to check it out. The fans appeared to be working, the coolant was a fair bit above the normal mark, but I'm not sure the water pump was running. I couldn't feel anything when I squeezed the top radiator hose. This is an '03 with about 50k miles on it.
I'll be taking it in Monday morning so I was curious what people's thoughts were. If it's the water pump is there anything else I should consider getting replaced while I'm at it? I'm still on the original timing belt, a change I've been delaying a long time since I drive so little so it might be time to bite the bullet and do it.
Golf IV / Jetta IV :: Harness Protection Coolant Temp Sensor
I just replaced my CTS, and I noticed that there is a small section of exposed harness wiring between the end of the loom and the CTS connector. I can't tell if it came loose when I swapped the sensor, or if it was this way for awhile, but all of the other harness connections around this area are completely covered and the loom end doesn't seem to clip into the connector or anything. If I were to try and seal it, I would need to use tape.
How hot does this area get? It seems like there shouldn't be exposed wiring here.

My CEL is on for P0116 Engine Coolant temp circuit, range or performance problem. I replaced the CTS, thermostat, and did a complete coolant flush/replacement last November. Car worked well over the winter no issues. Last week when the CEL came on it gave me P0301 and P0440 as well. I did a reset and the lights stayed off for the week. Then P0116 came back. Is it possible that the CTS is bad again? I measured the resistance on the CTS and hot it is about 300 ohms and cold is 2.45k ohms.

My temperature has been randomly dropping, them back to middle, and recently my engine was overheating because I'm guessing the fans didn't turn on, because I'm also guessing, the engine didn't know it was overheating?
Anywho, during my replacement, I made sure to get rid of the pressure, and the car was cold. I tightened the cap again, but when I took the sensor out, all the coolant spewed out.
Now if I understand this correctly, do I have a leak? I figured the leak I had was coming from the temp sensor as it is.
Here's some pictures for those who'd like to see ....
Golf IV / Jetta IV :: 2003 - Code P0118 / Coolant Temp Sensor Replacement?
I recently got the solid check engine light for my 2003 VW Jetta 1.8T GLS. I used a bluetooth OBDII dongle and Torque Pro to pull the code P0118. This seems to coincide with my symptoms:
Car idle at start in park stays around 1100RPM then in reverse it drops to 1000RPM then back into park and it stays around 900RPM and keeps that at idle.
If I start the car then immediately reverse out of my driveway then the car has a very rough idle but if I wait around 5 seconds in park idle then reverse out of my driveway it is smooth.
My car dash thermometer stays pretty close to the bottom low then after about 4-5 minutes it shoots up to 190F and stays. Gas mileage is also very poor.
I looked up a tutorial which shows the parts needed and how to replace the sensor : [URL] .....
I removed the engine cover and believe I found the coolant temp sensor in the spot the tutorial shows. My question is if there is anything I should be aware of before attempting to replace this sensor that this tutorial doesn't cover? I took a screenshot of what I believe is the coolant temp sensor.
Ford - F150 :: 1994 - Idling Slightly Unsteady / Coolant Temp Reading High Normal
1994 f150 with 4.9L I6; 180k mi.
Parked vehicle last night after using it uneventfully for work the day before. Upon leaving the house at 11:30 AM, I noticed that I'd picked up a new mechanical noise. Nothing major; actually wasn't sure I heard anything at all.
As I drove to the store, I noticed it was idling slightly unsteady...much less so than a missing cylinder. I resolved to check the high-tension connectors when I got home for security. I glanced down at the gauges to check and see if my oil pressure was good; I then noticed coolant temp reading "high normal."
When I got out, I noticed a small pool of coolant forming. I looked at where the puddle was forming...the radiator hose had come off! (Actually separate from the radiator connector, as one might do if draining fluid without using the petcock.) I popped the hood: no unusual smells. Nothing seemed abnormally hot. Placing a finger against the head was uncomfortable, but not painful. Spit expectorated upon the head did not sizzle.
I then called my wife, explaining the situation, and walked back home 2 miles. We then took the spare car, bought antifreeze, and added it about an hour post-shutdown. Where the car was parked seemed wetter than the light drizzle allowed; daubing a finger in it and tasting gave a slight sweet taste.
I tend to check my fluid every so often (not every day, though) and coolant was verified as "full" as recently as 100 miles ago. (I don't make a habit of crawling underneath, though, so I couldn't tell you if hose had been slowly backing off or not.)
As to cause: is it plausible that this could happen without foul play? There have been a few vandalism incidents in the neighborhood; it's also possible that I [peeved] off a neighbor recently. I'm not about to go any further than fixing, though, unless there's really no other plausible explanation.
As to the mechanical questions: How much damage was done? Did I "catch it" in time? What is suggested as far as repairs/maintenance? (I was planning on doing a compression test, and keeping a close eye on fluid levels over the next 1,000 miles or so.) Engine sounds completely normal.
Golf IV / Jetta IV :: 2004 GLI - Slow Coolant Leak
I have a 04" GLI and I was thinking about doing a coolant flush. Looks like I have a slow leak. I was wondering where should I look in order to stop the leak. Put some coolant in about a month ago and now the coolant light is back on. Every morning when I pull out of my driveway there is a small leak under the driver side of my car. Is this an easy fix? If I do decide to do the coolant flush myself what is the recommended coolant replacement?
View 4 RepliesGolf IV / Jetta IV :: 2004 - Overheating - Coolant Leak?
My 04' GTI, 24v VR6, all stock, @ 107,000. I had a coolant leak from the t-stat housing. I installed all new housing, seals, and C-Pipe from GruvenParts. Already had a green CT sensor installed and the kit I got didn't come with one, so I didn't change it. Found out the leak was from the t-stat housing o-ring didn't fit the old housing. The new one fits perfect. I put coolant on the seals and burped it. Doesn't leak a drop. But still overheating, all the hoses have pressure and are hot, so no blockage....I noticed the fans were not coming on at all. The fans used to engage every other minute and run for 15 secs on high ONLY. Longer times, if not constantly w/ A/C on. I was wondering how to test the fans, sender, and/or fan control module to see which one of them isn't working. And which pinouts are what?
View 2 RepliesGrand Prix :: Overheating But Temp Gauge Not Going Above Normal Operating Temp
I have a 2004 Grand Prix and it is displaying the symptoms of overheating but the temp gauge is not going above normal operating temp. I replaced the thermostat twice, and after driving for about 10-20 mins coolant comes out of the overflow. I'm at a loss, I'm thinking temp sensor(?) But I don't want to keep throwing unnecessary money into it. The fans work fine, the heater blows as it should.
View 8 RepliesGolf IV / Jetta IV :: 2004 - Coolant Leak On Passenger Side
I've got an '04 1.8t jetta with 158k on the clock. Recently noticed I have a coolant leak on the passenger side of the car. Started the car in my driveway and looked for drips and found coolant collecting in the front valence right underneath the intercooler. Took a look from the top and noticed the hose going into the bottom of the part shown in the picture is leaking like a sieve. It's the metal canister-type thing on the passenger side right next to the radiator. What part this is? And where I can get a new hose that connects to the bottom of it?

So this weekend my Y-fitting for the coolant hose (coming out of the reservoir) broke, literally after arriving at my friends house about 50 miles from home.
I "mended" it, and decided to try to take it home, as it is my daily. Temperature would get high, but not into the red, and drop back down. On the final rise, it got a bit too close to red for comfort. I drove about 25 miles, and my coolant light was on the majority of the time. The last 3-5 miles, my oil light came on. When I went to pull off the road, I pushed in my clutch and my car died. My first assumption was a head gasket (as I have been there before.
I open the hood and coolant is pouring out of my "mended" y-fitting. I check under the car - no oil, just coolant. The oil didn't seem to be "milky," but there seemed to be some sort of condensation on the filler cap. I checked the dipstick - not milky, just liquidy. I added some oil to the car, and had a friend bring some distilled water, and did a little bit better job of mending my fitting. I poured the distilled water in, and it started boiling almost immediately. I let the car cool for a couple hours and tried to start it, but nothing.
There's no white smoke, but the car just "puts" for a few cranks, and then it goes back to cranking. Looking around the engine housing, there doesn't seem to be any oil; but my car has a lot of grease on the block, so it's hard to say.
I did some searching, and it seems that it could be the oil cooler? I don't have the tools for a compression test, and the car was towed to a gas station, which is about 30 mins from my house.
The car is a 2004 Jetta, 1.8T Manual with the 5-speed.
Ford F-150 (2004-2008) :: Temp Gauge Reads Normal / No Pressure In System
My friend has an 08 4.6. He has replaced the thermostat with 3 different ones all with different temps, still nothing. Temp gauge reads normal but after driving it for a bit he can take off the radiator cap while it's running and not get sprayed in the face with coolant, almost like there is no pressure in the system.
View 6 RepliesGolf IV / Jetta IV :: 2004 Overheating - Radiator Cracked And All Coolant Leaked Out
Ok so I have an 04 Jetta 2.0 and lately it's been overheating on me. The first time it started overheating was because my radiator was cracked and leaked out all my coolant, I swapped the radiator everything was fine for a while. The second time I started overheating, I saw my primary fan was bad it wasn't spinning at all, I swapped it everything was fine for another while. I also changed the coolant temp sensor, it wasn't bad it's just because the coolant flange was leaking coolant, so I changed it a long with the O-Rings and sensor. I also changed the thermostat just incase that was the problem but it wasn't.
I don't think the fans are turning on by them selves when they have too, but either way the car still overheats when I turn on the fans manually with the A/C. I'm not sure if the coolant is circulating, as the car only begins to overheat when I come to a stop and it idles. I have a feeling it's the water pump but I wanna be sure it is before I change it. What it could be? Things that I should check for that usually go out?

I have an 04 gti 1.8t and last night it started over heating. I pulled over and checked the coolant and the oil but everything looked good. I let it cool down and drove it home. When I popped the hood there was a little steam coming from the coolant overflow tank but I saw no leaking. I decided to vent the pressure off the system and then I got a little drip on the passenger side close to where the inter cooler is. I can't pinpoint the leak though.
