Can head gasket leaking air into coolant?
Besides allowing coolant into the combustion chamber, an internal head gasket leak allows exhaust gases into the coolant. This can cause bubbles to be in the radiator or coolant reservoir making the coolant look like it's boiling even when it's cold.
What causes bubbling in coolant reservoir?
Bubbling indicates rising air pressure in the cooling system, which is a sign that the flow of liquid is blocked by a pocket of air. One of the most common causes is a blown head gasket, in which the air pressure inside the cylinder heads is transferred to the cooling system.
How long does it take to burn coolant out of exhaust?
It may take a few days to a week to burn off all this fluid out of the exhaust. One of the quickest ways to burn off all the coolant quicker is to hold the throttle at about 2000 rpms when in park for about 10 to 15 minutes.

Can coolant get gas?
Coolant gets directly into the Engine cylinders often when a head gasket fails, this results in decreased performance and smoke out of the tailpipe, but an engine can run for a long time in such conditions, so it's quite common for engines to run with small amounts of coolant leaking into the cylinders.
What does coolant in exhaust look like?
The smell of coolant and/or a whitish cloud of smoke from the exhaust at startup can be an indicator of coolant in the combustion chambers, which can be confirmed by a chemical test for exhaust hydrocarbons in the coolant.

Is exhaust fluid a coolant?
In part two, we examine coolants and diesel exhaust fluid (DEF). What each fluid does is fairly simple: Coolants moderate temperature to keep trucks on the road, while DEF works to lower the harmful gasses emitted while an engine works.
What was removed from the speed scope?
We also removed the speed scope raw water intake and cleaned the inside of it. The seacock was clean.
What temperature does a suspect motor creap?
After those repairs were complete the temperature on the suspect motor would creap to 190 degrees at WOT while the other motor maintained 180 degrees. Out of ideas I decided to change the fresh water coolant pump. While hard to inspect when on the motor it was obvious once we removed it. The bearing squeaked when spinning the pulley and signs of a leak from the weep hole gave it away.
What temperature should a car's cooling system be?
The cooling systems on your engines have to be 110% perfect with water temps in the high 80s.
What is the purpose of an infrared thermometer?
If your concerned the sensor/guage may be an issue an infrared laser thermometer is very useful to take temperature readings while underway of both engines…
How often do check engine alarms get serviced?
That said I don’t know when it might of gotten hot. Seems a check engine alarm would have sounded? The motors are serviced every 100hrs. Every winter the heat exchangers and after cooler is also serviced.
Why is exhaust vapor so high?
Excess exhaust vapor was because the raw water mixing elbow had a pin hole allowing raw water to mix with the exhaust gas prematurely.
Where are the Impellor pieces in a fuel cooler?
1. Impellor pieces in the hose from the intake to the pump or pump to the fuel/gear cooler.
How many miles does a 2000 VW Golf TDI have?
My questions are all at the bottom of the post but here is the related information:#N#Car History:#N#2000 VW Golf TDI with about 67,000 miles. Upsolute chipped for about half those miles. I’ve owned the car since new and have done all required maintenance plus new engine oil (used Mobil Delvac 1 5W-40) and engine oil filter every 5000 miles.#N#Problem Symptoms:#N#1. Engine Temperature Indicator spiked to high temperature at high engine load. Occurred on highway going uphill. No temperature problems on surface streets which is where I’ve driven the car since noticing the spike. Passenger compartment heater working. Occurred about one month & 500 miles ago.#N#2. Passenger compartment heater not working. Occurring for about two weeks & 200 miles ago.#N#3. Lost about 2 cups of coolant over the last month.#N#4. No sign of coolant leaks in garage. No signs of coolant leaking on engine bottom cover.#N#5. Fuel mileage has not changed.#N#6. Vag-com scan tool shows zero faults on all system modules including engine module.#N#Mechanic’s Findings & Conclusion:#N#1. pressure test overnight showed no leaks#N#2. replaced failed thermostat#N#3. coolant sniffer tool shows combustion gases in coolant when revved above 3000 rpm#N#4. coolant circuit is locked with air therefore coolant temperature gauge in instrument panel is not reading the coolant temperature in the engine#N#5. root cause was thermostat failing closed which caused engine to overheat and head to warp which caused leak at head gasket#N#6. conclusion - head gasket is blown#N#7. repair will be at least $1200 - $1500 (if nothing major broken)#N#My Questions:#N#1. Do you think that blown head gasket is correct diagnosis?#N#2. How common is this problem?#N#3. How much did chipping have to do with problem?#N#4. Any chance of this being covered by warranty? ( I know the chances are probably zero since I chipped it.)#N#5. Why the frig would any car builder use a thermostat that fails closed?!!!
What happens if the water pump fails?
And it is also likely that if the water pump failed, the engine would overheat whether it is being driven or not. If you are getting a lot of exhaust being blown into the coolant, you should see large amounts of bubbling in the coolant reservoir when you wind it up with the cap off the reservoir.
Why didn't they check the coolant for exhaust gases?
They replaced the water pump and coolant at no charge! The service coordinator said that they did not check the coolant for exhaust gases because they did not think that was the problem.
How to check if head gasket is pressurized?
The next morning, after the car has been off all night, squeeze a radiator hose to see if it's pressurized. If it is, the head gasket probably has a small leak.
Where is the EGR cooler on a car?
Karmann-diesel. Oly, The egr cooler is bolted to the engine in the rear of the engine bay, between the engine & the firewall. It's a cylinder maybe 2" in diameter with a tube connecting it to the exhaust manifold & another tube connecting it to the EGR valve.
Can EGRs clog up with oil?
The people who have had EGR cooler fail have noticed large and continuing coolant losses, and the EGRs clog up with the residue left when the coolant gets baked off. You are correct in that a leaky head gasket should show coolant in the oil as well as oil in the coolant.
What does it mean when your exhaust is cold?
If it's pressurized when cold, that's a bad sign. It means something is being added to the cooling system (exhaust). To test this, remove the cap on your expansion tank (while engine is cold) to vent any pressure that may be there. Next, do some driving.
