Golf IV / Jetta IV :: 2001 - Antifreeze Boiling Out Of Overflow Tank
Oct 17, 2011
OK, my '01 GTI VR6 has been giving me overheating problems - I've had to replace the crack pipe, and I've been having problems with the plastic fittings (coolant lines around throttle, heater core) all breaking. Turns out the electric fans were bad, I replaced them yesterday. I did check them, neither one was coming on with the AC on, and with 12V jumpered directly to them, still no go, so it wasn't the fan controller.
I was looking forward driving my car without overheating, but that doesn't seem to be in the cards. Looks like the fans weren't the only thing wrong. The sympton I see is that the coolant overflows the coolant overflow tank, but the temp gauge, while it comes up to temp (190 degrees) it doesn't go beyond that - but I'm having coolant boiling out of the overflow tank?!
I really don't want to say out loud - but maybe a bad head gasket? I've heard there's something that's like litmus paper you can use to see if exhaust gasses are blowing into your coolant - where can I get it?
What may be wrong? Almost anything would be better than a bad head gasket! While I've been having these problems, I've not seen the temp gauge ever go beyond the center 190 degrees, what's happened is that while driving the low coolant warning will come on, I pull over, and coolant is bubbling and overflowing the tank.

2001 Jeep Cherokee sport ... Just bought this Jeep with 145K miles. Had radiator and all hoses replaced. The overflow tank is boiling over but the engine is not overheating. Safe to drive? What should I be checking for?

Is it normal for a small amount of antifreeze to leak out of the small hole on top of my Jaz overflow tank? This is on a 73 Chevy small block.

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.

VW Golf 2000 2.0 GLS engine auto. 158,000 km
Observation 1: The coolant flange broken 3 times, which appear to be caused by pressure inside.
Observation 2: I drove it today to see the problem. During normal driving upper hill, the temperature turned to be higher than normal. 1 or 2 minutes later after red light, I turned off the engine. And then driving for 2 minutes after the green light, the temperature read appeared to go back to normal (a tiny bit higher than normal). Further driving 5-7 minutes, the temperature reading went to the high end again. So I stopped, opened the engine cover and can hear water boiling sound inside the engine. The coolant in the expansion tank was much higher than normal (above the maximum). The coolant is Prestone (not G12).
I would guess that coolant is not flowing inside. But the problem appears to occur randomly. A water pump issue? (replaced at 90,000km) Or could be the thermostat? Why cannot the pressure be released automatically?

This has been happening for awhile now, but whenever the gas gets to 1/4 tank and below (about 2 ticks from the red tick on the gauge) the car will stall for about 3 seconds then come back to life. If it happens while I'm stopped it will completely die and I'll have to restart it.

My truck is losing antifreeze. It seems to push it out over flow jug. I have changed thermostats. This work for temp but not problem. From what I have found this engine is reliable. 2005 Chevy Duramax....

My Buick's 03 lesabre overflow reservoir cap is screwed on and has a gasket in it so it cant possibly leak air. I'm still wondering how does air or antifreeze get displaced in a overflow reservoir container that has no outlet to breath unless its forced through only one hose at the bottom in- and there is always a little pressure in the container to push the antifreeze back into the radiator when it cools off at the radiator metal cap?

Have a 2007 Isuzu I290 four cylinder with 5 speed manual transmission with 116000 miles on it. have used Mobile One oil from day one and replace it and the filter about every 8000 miles. Twice in the last 20,000 miles the coolant overflow tank has been empty and an antifreeze puddle on the ground. Both times it was just before an oil change so the truck had gone roughly 8K and the engine oil was down about a half quart to a quart. Engine temperature gauge stayed normal, midway on the gauge, or very slightly above normal, never got hot. Can’t find a leak in the coolant overflow tank or hoses. thought it might be tied to the low oil so was going to check it on a more regular basis and keep it topped up. other than the coolant puddle twice, nothing leaks on it and thus far has been a nice, reliable, maintenance free truck.

2000 Chrysler 300M with 142K miles. Was a very reliable car until recently.
Problem began with boiling coolant in the reservoir tank. Then began to lose coolant at a high rate. I tried stop leak products and replaced the coolant frequently for a couple months. Some of it kind of worked, but the problem always returned. The car drives fine for about 10 highway miles then begins to steam out from under the hood on the passenger side. It gets about half way up the temp gauge, but does not really overheat. I usually stop when it steams out, let it cool, replace the antifreeze, then do it all over again. I've also tried a bunch of other things too, e.g., radiator flush. None of it worked.
The mechanic wants to replace the radiator. Says the system does not have pressure so there's no real way to determine if there are leaks in the engine. But he does know that the radiator is no good. I'm okay to replace radiator, but don't want to do it just to find out ten minutes later that I have a blown head gasket, which I would opt not to fix. I have read the tell tale signs of a blown head gasket, such as coolant in the oil, but there is none. My exhaust is white, but it's 5 degrees outside and it doesn't look whiter. I have seen some coolant on the ground at times.

My friend's '04 Sebring is still overheating even after these steps have been taken: heads were warped -- had a professional shave them down and rebuild engine; new radiator; new thermostat; then removed thermostat to try this way, and bled the system for air bubbles (more than once).
The car can run about five miles - then bubbling/boiling in the water recovery tank. The mechanic said there is a small crack on the water reservoir (a small plastic box) near where the bolt connects to the engine. Could this crack affect the pressure of the system and cause this overheating?

Bought a used 2000 Jetta, 2.0L AEG engine by the looks of it, 188k miles. Previous owner told me he did a bit of work on it, and acknowledged the coolant leak - have to fill the overflow ball about once a week. He said he recently replaced the timing belt, water pump, and tensioner pulley. Not sure if that has anything to do with it.
From what I can see it seems to be leaking at the outlet flange (see pics of rust).
Would any of this cause the water in the overflow ball to be rusty yellow (see pics)? Should I just go ahead and replace the ball and then the o-ring at the outlet flange?
I'm new to VWs, but am up for a bit of work to make sure it gets to 200k miles (bought the Bentley manual).

My 1992 Nissan Primera 2.0 slx is overheating, probably on its last legs. First time this happened the radiator overflow tank seemed low so I topped it up with glycerol and added some leak plugger to the radiator for good measure. The car drove just fine for 20-30km then it happened again. At the same time, and I don't know if this is relevant, the windscreen defroster, which should bleed warm engine air, now only gives cold.

Having a problem with the 2008 Sonata GLS. When filling gas tank, pump nozzle clicks off, but gas flow continues, creating a significant spillage.

I was wondering if I can replace my overflow tube for my gas tank without replacing the whole gas tank. I know I will have to drop the tank and get new straps to install it, but would I need a completely new tank or can I buy an overflow tube separately?

When filling the gas tank, the pump shuts-off (as it should) unless the tank filled very-very slowly. It has overflowed/spilled before the pump even shut-off in some cases.
CEL is not on. DTC 16826 stored: "EVAP Emission Contrl.Sys (small leak) Leak Detected". I just got a VAG-COM cable but haven't got the software going
yet.
Bentley has some diagrams for the fuel vapor recovery system but that's about it. Seems like there's something with the fuel vapor recovery / venting system going on. How to further diagnose?

1998 Mitsubishi Eclipse. 2.0L 5-speed. 195,000. When I complete my 33 mile trip home and shut off engine, I can hear air bubbling into the overflow tank from radiator. Temp gauge shows normal. Just had new water pump, thermostat, radiator flush and refill and new 16 lb radiator cap installed. Overflow tank fills up to near top (not running over) and when engine cools, the tank is back down to half way. I've checked water level in radiator when cool and it is full. Question: Is this normal? Don't think I've ever noticed or heard the bubbling sound before. The engine runs great and smoothly.

I have a 1999.5 Jetta 2.0 question:
When I run my defrost with the heat on, I smell antifreeze pretty strongly. I am also having trouble keeping the windshield defogger/defrosted without the heat constantly blowing on it. Signs point to heater core, right? So I tried a bottle of Bars Leaks aluminum radiator stop leak with the metal flakes in it. When I run the heat on the feet or front/face/torso setting, it does not smell like antifreeze (unless it's when it very first starts and it's so slight that I don't notice). When I run the defrost with the heat on, it smells pretty strongly of antifreeze. I see no antifreeze on the passenger side carpet.

Car leaks anitfreeze once again. The first time my hose exploded and my temperature light came on. Car was towed and my fans stopped working. Got that fixed. When this happened my car was on park. I turned on my fans and the fluid was leaking from the cap of the container. The whole anti freeze was everywhere. I am guessing something messed up in the engine so idk what to do anymore. I filled the anti freeze container with water and drove home with no problems. I don't know whats wrong with the car I am at the point where i just want to get rid of it. Car is a 99 vw golf gls 2.0 140k ....

Just finished a timing belt job on my 93 celica 5sfe. Filled the coolant up and burped engine. All seems to be well. My question is related to the coolant overflow tank. The cap has a hose attached on one end coming from the radiator and another coming out the other side that is short and L shaped. The L shaped hose isn't attached to anything and is open allowing air to either vent out or vent in to the overflow tank. There isn't any place nearby where the hose might attach to. Is this hose supposed to be "unattached" as it is now or should it be closed to create vacuum for the overflow tank to allow coolant back in to the radiator?

Aside from other issues I am having with my prius, this was one lurking. I originally thought the prius was "using" the coolant insufficiently. Anyhow, I bought this prius from a private dealer....(know how that goes)......
