It is probably the problem. To make shure that need to change the gaskets, one of the symptoms use to be thet the temp rises when you are running at speed 50+ average, where is supposed that the car gets a lot of air due by the speed and nobody thinks that will be overheated.

SOURCE: overheating problem on a 1998 BMW 318ti

Perform a liquid block test (with the bottle of fluid over the radiator mouth.) If the blue liquid turns yellow or clear, you have hydrocarbons entering the cooling system (usually via head gskt.) If not, you have ruled out a costly repair.

Sounds like it overheats pretty easily, without t-stat! This block testing liquid is cheap, and will verify a suspected leaking head gasket without lengthy diagnosis. Hope it's better news, but good luck!

SOURCE: can't bleed coolant system on Audi A3!

In my experience with Audis, after any job requiring changing/draining the coolant the car ideally needs to be driven. With the coolant topped up to max drive the car, keep the revs up and shake the car with steering and over bumps where possible. Whatever you do make sure you take at least 2 litres of water/coolant with you, as as soon as the air lock goes, the level drops a lot and quickly. Also keep an eye on the temp gauge and avoid letting it go much over 90 degrees (over 90 on the gauge usually means its well into the hundreds) When you get consistant hot air through the heater, at idle, the level should of settled. If this doesnt work you may have thermostat issues or a blockage. Good luck, let me know how you get on.

Will an air pocket in the coolant system cause it to overheat or over pressurize on a 2001 Nissan Sentra ?


1. The radiator cap if working correctly it will release pressure in the system provided the cap you have is the correct pressure setting. If you are having a problem with pressure then replace the cap with a new radiator cap with the correct pressure setting. Do not use a cap with a pressure setting other than the original equipment pressure spec. So you do not go to the parts store and buy any radiator cap on the shelf that fits because they come with different pressure ratings and some of these will be totally unsuitable for your car.

2. If the pressure valve is stuck in the "old" cap the pressure release system will not work.

3. Overheating
Air pockets in the cooling system can definitely cause overheating and can retard coolant flow through the system. If you are draining the radiator to replace the coolant or replacing the radiator you need to follow the correct procedures for bleeding air out of the system for that particular engine after coolant refilling. Some engines have bleeder screws on the cooling system to assist in the air bleeding procedure and some don't.

There are various causes for overheating so don't assume it will necessarily be solved by bleeding any remaining air from the cooling system and replacing the radiator cap with one that works.

Other causes can be...........
1. Faulty cooling system thermostat. (Replace the Thermostat)
2. Faulty water pump, especially if the impellers have corroded away or have disintegrated in the case of those design genius water pumps with plastic impellers. (Replace the water pump)

3. Cooling fans not working and if so the cause needs to be tracked. Check that your fans are kicking in. If the engine is overheating the fans should be running because they will switch on when the coolant reaches a specific temp and well before the coolant gets excessively hot.

4. A partial blockage in the coolant passages inside the engine but not in the radiator if you have a new one. If the coolant is not changed at the required intervals(frequently the case with many owners) or is over diluted with water you can get a build up of debris. If products like stop leak have been used in the system this can create similar problems with partial blockages inside the engine coolant passages.

5. A compression leak into the cooling system.
If you have bled air from the system and have continuous air bubbles in the cooling system I would suspect a compression leak. In that event a basic leak down test will show if you have compression gasses leaking into the cooling system and from which cylinder(s). The spark plug is removed and compressed air is forced into the cylinder via the spark plug fitting and air bubbles will show up in the coolant of there is a leak into the cooling system.
--------------------------------
Have the problem with overheating addressed immediately. Running the engine with an overheat condition will cause expensive engine damage many times the cost of fixing the overheating issue.

The blazer has over heated twice in a week. I noticed steam bubbling out of a hole on the top of the water pump behind the pulley. Is the water pump bad?


Very possible that indeed the water pump is bad. These things do have a lifetime, and 15 years isn't all that short a time.

Check your oil for coolant. Looks muddy or diluted. Check for air in the cooling system.

Engine overheating i have replaced the radiator has plenty of water


replace thermostat.then bleed coolant system, this is how you do it.fill the cooling coolant system with 50 / 50 dexcool and water to raise boiling point,straight water will evaporate boil away cause engine to overheat catch fire thats why you need 50 / 50 mixture antifreeze and water.to bleed coolant system first fill coolant system until coolant stay at the full cold mark on the the coolant overflow jug,then you start engine allow it to idle,place the heater and ac control in any ac setting except max and the temperature control to the highest setting,run engine until lower hose to water pump is hot. with the engine hot run the engine speed up to 3000 rpm and allow it return to idle, repeat this 5 times. slowly open the bleed valve on the thermostat housing or look for bleed valve at the water pump heater hose.open bleed valve for 15 seconds to expel any trapped air.then top off the coolant as necessary,and when top radiator hose hot thermostat open up.keep adding cooling to overflow until coolant level stop at full cold mark dont over fill coolant.if engine seem like overheating while looking at cooling gauge turn off engine wait a while until cool off add more coolant until coolant level stay stable and dont drop any.when open radiator overflow cap use large rag over the radiator cap to keep from getting scald open radiator cap a little at a time but dont open radiator cap until engine cool down first.replace the radiator overflow cap, thermostat,and engine coolant temperature sensor and check the cooling fans fuses and relays see what happens.

your car is severely overheating. take it to a repair shop and have it checked. it sounds like you are low on coolant, if you only get cold air out of vents, it usually means you you have little to no coolant in the system. you could have a lot of air in the system also. try bleeding the coolant system.

2005 cadillac cts base water pump replaced by unauthorized dealer. Now "check coolant light is coming on again" Any thoughts on this matter


If there is no indication of overheating, the check coolant light is probably triggered by a sensor indicating low coolant level. It's also possible that there is air trapped in the cooling system from when the water pump was replaced. Trapped air could cause the sensor to throw the trouble light. Bleed the air from the cooling system and see if the light goes out. You may have to clear the light after bleeding the system.

1st make sure your cooling fans turn on. If they do, you probably have air in your cooling system. If you don't know where the bleed valve is or how to bleed the cooling system, check out this link. COOLANT BLEED VALVE

Why is my car overheating? i ave replaced the intake gaskets, water pump and thermostat


with replacing all these items, i assume a fair amount of coolant was lost, and hopefully you have topped it up......the thing with topping the radiator up, is that you need to be sure that you bleed the system of air, as in open the bleed screw, or keep the radiator cap off until the engine fan turns on and the thermostat opens up, indicating the coolant is flowing around the entire system

If you dont bleed the system proplerly, and there is air, what can happen is that the air accumulates at a high spot and causes localised heating, and if this is around a sensor sopr, it could indicate overheating, even though most of the system is getting water

I hope this helps

Overheating on ford bantam


there are three probable causes that may result to overheating one inadequate circulation of coolant within the cooling system. The radiator is clogged with dirt some stems are closed.try to flush the radiator using rad flushing fluid. Second improper bleeding of trap air within the cooling system. Third the water pump blades are worn out inadequate circulation of coolant.

HOW DO YOU PURGE OR RELEASE AIR ONCE YOU REPLACE RADIATOR, WATER PUMP AND THERMOSTAT?


the thermostat (on bmw replacement parts) have an arrow that has to be installed facing upward.if this was done correctly,to bleed the system usually there is a bleeder screw on or near the expansion tank(where you fill the coolant) and possibly on the thermostat housing. i would recommend opening both bleeders and keep filling the system with coolant closing the lower bleeder first and then allow the rest of the air purge from the other bleeder screw.make sure the coolant stays full and be patient you can't wait TOO long.
