Golf IV / Jetta IV :: Coolant Leak From Behind Thermostat Cover So Soon?
02 Jetta 2.0L that I changed the thermostat. o-ring, and cover on when I first got the car about a year and a half ago.
I see dry g12 coming out from behind the cover and my coolant bulb had dipped quite a bit in recent weeks requiring a refill. What is most likely the problem here in such a short period of time? I've only put like 10k miles on the car in that period. O-ring couldn't have seated wrong because wouldn't the problem have been apparent immediately back when I did the job? Maybe I need to re-torque the cover? Cracked cover?
Golf IV / Jetta IV :: Replaced Thermostat Now Alarm Going Off All The Time?
So I replaced my thermostat today... to do that I unhooked the negative terminal of the battery, removed the hose off the thermostat housing (I think that's what it's called) and disconnected the switch to the alternator as well as take off the 13mm jam nut holding the wire to the side of the alternator. I reconnected everything up, put the key into the ignition and just turned it before starting the car and the alarm started going off. I disabled the alarm from controlling the lights and horn by unplugging the electrical connector just behind the fuse panel so I could do some errands today. I then disconnected both terminals on the battery and touched them together to reset the ecu.
After reading that holding the key into the door lock until the windows roll down would reset the alarm; this weekend I'm going to hook up my driver side door lock mechanism (been a little lazy) and give that a try.
Golf IV / Jetta IV :: Exhaust Manifold Is Cracked?

View 1 RepliesGolf IV / Jetta IV :: Thermostat Replacement / Constant Leak From The Housing
Finally got around to replacing my Thermostat because the DIY here made it look so much easier than removing the alternator and such. Did everything exactly as described and after assembling everything with the new t-stat and O-ring I am getting a constant leak from the housing. I tried removing everything and reassembling...all the bolts are tight. Plastic housing isn't cracked and seems to be in great shape. Everything lines up properly but coolant is just running out of the bottom of the housing. Am I missing some magical trick here?

My son has a 2002 Jetta, we just changed the water pump and the thermostat. The car will sit at idle and the temperature will stay around 190. When you drive down the road the temerature will rise and when you let off teh gas the temperature goes back down. What this could be, I have tried everything I can think of to fix this car.

My 2000 Golf 2.0 started making a bit of noise on start-up and also if I rev it to say 2000RPM and then when the RPM goes back down it will hear some sort of "knock". After the car heats up as far as I know the noise is not there anymore.
This only happened today so I though I would check the oil level. It is fine but the dipstick was almost completely covered by air bubbles.
Golf IV / Jetta IV :: Constant Steam Of Smoke From Dipstick Tube?

View 2 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?
Golf IV / Jetta IV :: Misfire On Cylinders - Cracked Harness / Vacuum Leak?
I just bought a 05 1.8T Jetta 116,000miles. and need diagnosing it. It misses all the time. Has new plugs I tried two other sets of coils (from my 2.0 a4 and my dads passat) and it made no difference. The SAI was taken out but nothing is blocked off. Also the coil pack wiring harness has cracks on the big brown wire where it goes down along the block. I'm getting these codes on my vag-com.
16687 cylinder 3 misfire
16686 cylinder 2 misfire
16688 cylinder 4 misfire
17766 cylinder 2 open ignition circuit
17763 cylinder 1 open ignition circuit
17769 cylinder 3 open ignition circuit
17772 cylinder 4 open ignition circuit
So am I correct in thinking that it's from the cracked harness? An not a vac leak?
Elantra XD (2001-06) :: High Oil Temp And Still Overheating After Replacing Thermostat
So my 2005 elantra gls has been having overheating problems. A few weeks ago, it overheated one day driving around town for about 30 minutes. I kicked on the heater and made it home. I went out the next day and didn't see any problems. Everything went fine for two weeks, then yesterday the problem happened again. I read about the thermostat often failing, so I did some research on that and replaced it today.
For replacing the thermostat, I followed the lower hose and found the housing, removed it and took out the old thermostat. Removed the old gasket, cleaned around the connection, dried it off. Then I put the new thermostat in , put some gasket sealer down and putthe new gasket on. Finally, put some more sealer on the outside of the gasket and put the housing back on.
After replacing it and immediately turning on the car, I got a High Oil Temp code. I cleared the code and let the car idle for while. After about 15 minutes I went for a drive around the neighborhood and then took it out on the highway for about 10 minutes. It started overheating by the time I got home. I turned it off and when starting it again I get the High Oil Temp code.
Is it possible that I didn't do something correctly with the thermostat. If not, what else could I look for and could I have bumped/damaged the oil temp sensor?
Golf IV / Jetta IV :: Brake Vacuum Line Is Cracked After Check Valve On Intake Side
Question, I have a 2003 VW Golf GLS 2.0L AHV (5 speed). The brake vacuum line is cracked after the check valve on the intake side. I looked up the part number on the hose (at work and don't have it on me at the moment), did some research and noticed some revisions to that part number. Eventually settled on [URL] ..... (I ordered a new one since I needed to order a few things). Needless to say, I am beginning to think I ordered wrong.
I noticed that the check valve on the new hose has a 3rd piece that a smaller hose looks to clamp on? The check valve that is in my car doesn't have that. Did I order the wrong part? or did I need to be a cap?
Golf IV / Jetta IV :: 2001 - Cracked Oil Pan - Loud Ticking Sound At Idle - Engine Blown?
I own a 2001 Jetta 1.8t with Gti front end. So I was driving downtown the other day and I bottomed out really hard and cracked my oil pan. I didn't realize it was cracked and leaking so I drove it home, drove fine with no issues at all. When I got home I parked it and went inside and in the morning I came out and tuned it on for maybe ten seconds. It made a really loud ticking sound that was constant and oil pressure was almost all the way down. So I shut it off and looked and saw the oil pan. I fixed the oil pan yesterday and started it up and it sounded really good and drives fine. But I've been hearing a pretty decently loud ticking sound when everything's up to temp and warmed up. The ticking is only at an idle and it drives like it use to just sounds bad at an idle. Some people think it's my oil pump and tensioner, some people thing I ruined the turbo and possibly internals.

My 2003 Jetta sunroof drains aren't clogged. Nor are they simply cracked. They don't seem to be connected. I tried snaking them out with trimmer line- the thing took like 15 ft of line without resistance, from either end. I suspect they had a mechanic who tried to use compressed air to blow them out, and may have blow the line off its nipple instead.
So I can't install a new, smaller line inside the old one. There's no way to fish the line from one end to the other.
I'm doing the headliner anyways. I can replace them, but I need to know what type of tubing is actually used. Plus, how that tubing would go down the A-pillars and meet up with the rubber nipple? Can that thing be pulled out from the outside of the door jamb?
