Golf IV / Jetta IV :: Overheating - Temp Stuck At 190 Usually For About Ten Minutes Then Starts To Climb
Jun 29, 2015
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?

I got a mk4 where the temp gauge starts to climb to 3/4 instead of halfway when I'm idling for a while.
1. fans don't come on
2. if I turn on ac, fan come on and temp stays at 1/2
I tested low and high speed on fans. both operational. Is it the fan control module, temp sensor green top, or radiator s/w?

Having an intermittent problem on my 2002 Chrysler Sebring LX (about 132,000 miles). Often I can drive around and everything is okay. However, it seems like every 11 days or so, the temperature gauge starts to climb above the halfway mark and toward the danger zone. Only once has it gotten all the way up to the red danger zone and illuminated the warning light, and that was the very first time. It was fortunate that this happened the exact moment I reached home and parked in my driveway.
When the temperature gauge starts to climb above the halfway mark, I've tried to turn on the heater to cool it down, but this doesn't work. The heater just blows cold air. So far I have been taking the following steps:
1) Stop driving and park the car for 10 minutes or more.
2) Fill the coolant tank under the hood with coolant. I'm putting in about half a gallon each time.
3) Continue driving.
After this process, the heater is again blowing warm air and the temperature gauge is staying at a safe level. It seems to persist for about 11 - 14 days then the cycle starts all over.
It happened last night following a drive of about 5 miles home from the gym. Since I had no more driving to do that day, I just parked it overnight to see if this was a fluke and if it would be necessary to add more coolant.
This morning I drove the same 5 miles. Temperature gauge stayed pretty low for about half the trip, but then rapidly shot up. I got to the gym before it reached the danger zone (it was probably about 3/4 of the way up). I parked for a little over an hour while I went inside to exercise. Then I again added half a gallon of coolant and drove home without problems.
The last time I had overheating issues, the coolant rapidly spilled out of the bottom and the overheating was not preventable. I got the radiator replaced. This was in October 2013. I've also tried some of that stop leak fluid. It didn't work, but I'm not so sure I used it correctly. I didn't flush the tank and I think I might have poured it in on a normal driving day (coolant pretty full).

I have a 2001 Nissan Frontier Crew Cab XE with a V6 (without the supercharger). I bought it on Halloween night with only 42,000 miles. It now has 112,000 miles on it. I moved from Georgia to Kentucky and heard that I needed to have the cooling system flushed/filled to prevent it from freezing in the winter time. I then noticed that it would periodically "overheat." The temperature gauge would climb up to the line just below the "H" and then I would turn on the heater.
I read online about a "bleeder valve" on top of the intake manifold. I loosened it, squeezed the radiator hoses to get all of the air out and then tightened the bleeder valve. I then let it run until the thermostat opened, revved it up to 3,000 to let all of the coolant flow. Now, at various time with no specific reason, it will run fine and then just "decide" to overheat.
I can drive it on the interstate for fifteen minutes, park it in front of my house and then have to "tack it up to 3,000" just to get it cool. I've changed the thermostat and had the water pump tested. Neither of them are faulty. My mechanic vacuumed out all of the air from the system with a special tool the dealer recommends using and it still does the same thing. What's going on with this vehicle?

This is what its doing... Im starting to feel lost about whats wrong. I start it up and everything is fine. With in about 10 minutes it starts to bubble and spit out a little water then shuts its self off. And the gauge on the dash never reads above 190. And the fans don't come on unless i turn the ac on. And the ac still blows cold. The lower hose stays cold. I just replaced the thermostat and the water pump. But it changed nothing. Im thinking maybe its clogged somewhere. Maybe in the heater core or the radiator.

So I just bought a 2012 F250 with 28,300 on the clock. I was driving it home yesterday (500 miles) and I noticed that every time I shut the truck down the external temp display would display -40 F at start up and then gradually climb to whatever the ambient temp is, around 60F but in that 500 mile distance it seemed to be stuck at whatever the high was and not drop unless I stopped the truck and powered it off and we would start at -40 again.
Where I should start troubleshooting this? I have some factory powertrain warranty left but this will not fall under that so I need to fix it myself and there is nothing in the owners manual about this. Oh it is a crew cab long box, with the 6.2, XL package but has all of the benefits of an XLT it just has vinyl floors.

So to start off, its 10 degrees here with a -7 degree windchill. With that in mind, I was driving home just now from dropping off a friend, and noticed my engine temp was slightly about 190. Didn't think much of it, but within a mile down the road the temp was crossing the final line before the red 260 degree line. I pulled over and let it get down to 190 (luckily didn't take long) but in the next 3 miles home it rose again, then fell, and then rose again as I drove through my neighborhood. I'm thinking maybe the thermostat is going bad...? There's no way it went from normal operating temp to almost overheating as cold as it is....

Before I go buy a Bentley manual to dig around, when should my radiator fans kick on. I had the car idling for 10 minutes, no ac or heat on, and my coolant warning light came on, it overheated. It already has a new fan switch in the radiator, and the fuses are good.

My 2002 Jetta VR6 is overheating. The car only overheats when the car is not mobile. If I get stuck in straffic or just let it idle it will over heat. What could it be?

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.

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 ....

I have a 2002 Volkswagen Golf 2.0, I was driving and the temperature gauge starting raising pretty quickly. I stopped, checked the coolant and oil, both were at normal levels. The car cooled down pretty quickly, and I drove a little and it raised again. The heat is coming out cold despite the hot temperature. Overheating, normal coolant levels, no heat.

I bought a 2003 Jetta automatic w/ triptronic.
When the engine is cold in the morning(when i go to work) engine light(CEL) comes on and the car remains stuck in 2nd shift for 5-10 min(happens 1-2 times a week).
When I get back from work car goes well and the CEL is off.
I went to a shop and I found 4 codes:
00300- transmission fluid temperature sensor(G93). not a plausible signal-intermittent
00526- brake light switch- F short with power-intermittent
00652- gear monitoring not a plausible signal- intermittent
01045-tiptronic switch (F189) not a plausible signal- intermittent
I was thinking that it's possibly a transmission control module gone bad, but I'm not sure.

My 99 2.0 jetta tends to flash the temperature light on cold starts and when the cars running for a while and im not moving (traffic) the light flashes and starts to overheat. Whats the problem? The previous owner had changed the radiator begire i bought it but can it. I need a new radiator fan or is it my thermostat?

Why is it that after 15 minutes of idling the coolant starts to boil up and spill and the car begins to overheat?

I've noticed that in the past week or so, whenever I'm stuck in traffic for a few minutes, the engine temp will slowly rise. it gets really bad if traffic is crawling; the temp has reached that 2nd highest line before the red area.
Whenever I get going again and hit the gas, the temp drops. What it is?
Car is currently at 86k miles. I don't believe the water pump has been replaced yet.

So, I recently bought a 99.5 Jetta. (99 with a 00 body), fixes a few things. Alternator, oil pan, head gasket. I recently drove the car just up the road, drove it back. Went to pull in to my spot and it shut off! Wouldn't start but would crank over. Days go by, same problem. Runs for about 10 minutes then just dies. Fuel pump works, fuel filter isn't clogged. And the fuel relay works.

Got my 1979 Ford Bronco (351M engine) from my father. He had it in Colorado, mostly in a garage. Had 82,000 miles when I got it and has 67,000 miles now. Runs fine when the outside temperature is less than 80F. Above 80F, the will get hotter and hotter and the temp. gauge will climb. When the temp. gauge is 2/3 of the wat between Cool and Hot it will start to buck and cut out. Eventually the engine will stop. Then I have to wait for it to cool down to repeat the cycle. I have replaced all hoses, radiator, thermostat (3 times), radiator cap, carb. I have installed SS louvers in the hood. Heck, I have even "burbed" it (see Internet).

I have a 2002 F350 v10. I have 101,000 miles on it. When the Speedometer hit 15mph it starts to climb Rapidly to a 100mph then it stops and goes to 0. My miles go blank and when I slow down to around 5mph it comes back. I do know that I have a bad clock-spring and am changing that this weekend.

I have a 2003 vr6 with about 60,000 miles on it and it overheats. I can drive between 35-40 mph and make short trips no problem but when going any faster or accelerate faster than an old lady in a buick, the temp gauge slowly rises(or fast if i accelerate fast.) Until the "stop, check coolant" warning comes on(which i don't let get to that point.) it blows heat all the time, all the hoses get hot, I am no professional by any means but i have dealt with many different overheating issues with other vehicles but I am kind of stumped at what to try first so i don't end up replacing something that doesn't need to be because i do not have the extra $ to do so. The problem started when someone put dirt in my coolant, I flushed out the system twice, the second was just to see if anything else had loosened up that I may have missed the first time..

So recently my car has been starting to over heat. not to the extreme but the temp needle is going past the middle. only happens when stuck in traffic but as soon as I start going it goes back down.
As far as iv noticed only thing getting me puzzled is my fans are not running when running and starting to overheat. they run when I shut the car off though. The radiator is less then a year old. fresh oil change and the coolant is fine
