Mk4 Jetta Gli 1.8t , car was over heating only when sitting 5+ minutes at idle, mechanic said the big fan needed replaced so he replaced it. Car still over heated so i replaced the coolant with G13. It hasn't over heated yet but got in the car this morning and the coolant light started flashing and car was telling me to STOP the car. Checked out the coolant and it was on the low side. What it may be? Leak somewhere? Bad thermostat or water pump gone bad? Timing belt and water pump were done when i bought the car when it had less than 50k miles, car now has 99k miles on it.

I have a mk4 Jetta 1.8t. Problem started last night. After I drive for about 15-20 minutes the oil pressure warning light comes on. It doesn't feel any different and my oil is full. Could my pump be going bad? I hear a slight tick near the bottom of the engine on the passenger side. But the car idles fine and drives fine too.

Car: 2003 Jetta VR6 GLX 24V
Sometimes when I start up my car ( I want to say when cold, but I haven't tried after its warm yet), the coolant light and warning come up. I obviously checked the coolant, and it is a little low. But it's been where it is since I bought the car, and I haven't noticed any leaks. After I turn the car off then on again the light goes away.
The car is running perfectly fine, it's not running hot or cold. Another thing I have noticed is that my fans don't seem to be working. ( I know it's a common problem). But I'm thinking this could be the fact that it's below 0 today.
I haven't gotten it scanned yet, but what's going on; i.e., Thermostat, sensors, fans etc..

View 3 RepliesGolf IV / Jetta IV :: Overheating - Temp Stuck At 190 Usually For About Ten Minutes Then Starts To Climb
I am trying to troubleshoot an overheating problem so that I may fix it myself. Not sure if it's thermostat, sensor, or a blockage.
'04 Jetta tdi with about 200k miles. Temp sticks at 190 usually for about ten minutes then starts to climb, varying between the 207-225F mark. Hasn't gone any higher, even in high 90sF ambient temps after 30mins driving. Holds fluid fine, pink G12 mix, and no bubbles or milky appearance to oil dipstick. Recently installed new AC compressor, txv and dryer so I imagine I can tackle thermostat or sensor if need be. Where to start?
Golf 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?

After finally getting some issues sorted this weekend (needed a transmission flush) I was driving around a bit to make sure everything was good. On the way back to my house, the car started overheating. I replaced the thermostat this winter (~4-5 months ago) because it was stuck open making things run a little cool.
I was thinking the water pump is probably shot but not 100% sure. the radiator fans both work and when I turn on the heater, it blows hot. Any good way to check if the water pump is dead? I have a little point and shoot infrared thermometer and one side of the coolant line was way hot and the other was fine (cold ~90 deg F).
Golf IV / Jetta IV :: 1.8T AWP GTI Overheating - All Of A Sudden Coolant Starts To Flow
I am having a overheating issue with my 1.8t AWP gti, it goes as fallows, start the car, engine warms up go for a drive (short 5-8 mi), park the car and temp gauge starts to rise, (turns off car)... I began to check some things with the system, I checked both rad hoses bottom is hot top is a bit hotter and fans work when ac is on; here is where it gets interesting i took off the coolant return hose on the reservoir (cold start) and nothing was flowing ...water pump?... So i turned the heat on and air full blast and all of a sudden coolant starts to flow.
It also seems like air is being spat out as well. Soon after the flow beginning my coolant in the reservoir starts to fluctuate (rising and dropping) with air bubbles and beginnings to over flow so i shut the car off. Now I know what the possible issues are its either the water pump, air in the system or bad autozone thermostat. Here is some history of the car TB was replaced at 70,000 by Previous owner, i bought the car had the belt inspected and was told it was good, about 2 months ago i had a coolant leak and had it misdiagnosed as a thermostat housing leak; it turns out it was a coolant bypass hose that was leaking so i ended up fixing it. I lost a lot of coolant but topped it off with g12+. My mechanic doesn't think its the water pump and recommended changing the thermostat for an VW one another mechanic recommended to bleed air of the system.
Golf 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?
Golf IV / Jetta IV :: 1.8T Oil Pressure Warning Lights Comes On After 2 - 5 Minutes Of Car Running
I have an oil pressure warning light on my 03' GTI 1.8t. It started as a sporadic issue, it would beep and flash for about 1-2 minutes than go away for about 20 minutes and return and repeat. I drove 130 miles on it due to an important meeting for work.
-I than changed the oil pressure sensor ( i found the old sensor housing full of oil ) and than the light stayed on after the car warmed up.
-I changed the oil pump with an OEM unit. Also changed the oil pick up- Issue still exists.
The light only comes on after 2-5 minutes of the car running. So I'm wondering if the oil is heating up and becoming less viscous than not allowing the pump to pump it as well or the sensor not picking it up.
I have oil and am not leaking it. I'm confused on what it could now be. I'm having it towed to my buddy's shop for him to take a gander when he gets a chance.I'm wondering if the cluster itself is bad.
Golf IV / Jetta IV :: 2001 - Engine Overheating - Coolant Temp Sensor Replacement
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 :: Overheating - Coolant Spraying Everywhere Causing White Smoke Under The Hood
I have a 2002 VW MK4 1.8t. It has 172,000 miles on it. Since i bought the car i have had to add coolant from time to time due to leaks from various plastic coolant parts so I replaced the crappy plastic connectors and flanges as they failed but it has never overheated till a couple days ago. It rose up to about 210'F but I didn't let it get to 260'F (aka the red zone).
While the temperature was up, the coolant was spraying everywhere causing white smoke under the hood. I stopped and looked under the hood and came up with the conclusion it was the coolant flange that holds the temp sensor since it was leaking coolant from the flange like a faucet hince the reason it caused it to overheat due to lost of pressure and no coolant in the system. So I replaced the part and gaskets then checked for other obvious leaks.
No leaks are shown nowhere else in the vehicle. So I added coolant to the car and let the cooling system do its magic as i left the heater on high. Let car idle with cap off and heater on for about 45 minutes. No signs of overheating. So I take the car for a spin and that's when the car starts heating up. I look under the hood and feel hoses and notice all are pressurized but top hose that leads to coolant flange is hot and the bottom hose connected to thermostat is cold.
I checked the return hose that leads up to the coolant reservoir to see if it's cycling and it appears it was. At low rpms the return hose had a steady flow and at high rpms it was flowing much rapidly. Which made me think it wasn't the water pump also this car with that many miles wouldn't have lasted with the plastic impellar this long if it wasn't already swapped out by previous owners. My question is what would cause it to still overheat? I forgot to note the fans did not turn on when the temperature was rising unless i turned the a/c on. But i still did a drive test with a/c on and it still overheated. I also did multiple burp cycles. I have invested alot of money in custom work and suck to leave it parked on the drive way.
Golf IV / Jetta IV :: 2000 GTI VR6 - Coolant Leak / Smoke And Starts To Overheat When Idling
I have a 2000 vw Gti vr6. It leaks coolant smokes and starts to over heat when idling. Does fine when driving down the road. It has a new radiator. When pressure tested I can see a little stream of coolant coming out. But there's no space in the engine bay and I can't see exactly where it's coming from. Like I said it only happens when it's Idling for an extended period of time. It does fine going down the road.

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.

View 13 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.
