It sounds like a faulty thermostat. Follow the main radiator hose to where it hooks onto the engine. The thermostat is located inside that housing. But is the cooling fan operating? Do you see any leaks at the radiator, hoses, or water pump? The water pump should have a "weep hole" and coolant will be coming out of it if the water pump is defective. Hopefully, it is the thermstat, that is an easy fix. Hope this helps and good luck.

07 town car...after I drive my car for a smokes a little when I cuts it off plus I hear a bubbling noise

bubbling noise is the radiator boiling. If you have a viscous fan hub the have it replaced as the engine is getting too hot. When you stop an engine thee is still heat being transferred from the combustion chambers into the coolant. When the engine temp is close to boiling , this heat will cause the coolant to boil when you shut the engine down

Resivoir boiling over,,,,94 jeep grand cheorkke

If the fan is working ok there are still a number of things that will cause your vehicle to run hot and have the fluid from the radiator boil over into the resivior. It is possible that the thermostat is not opening up and allowing the coolant to flow through the motor and radiator properly or that the water pump is not working properly also causing the same issue either due to a missing belt or warn out bearings that have locked up. It is really impossible to tell you exactly what the problem is with so little information but those are the first two things that I would check out.

If your losing coolant water pump may be leaking, not enough coolant will make it overheat. If not that, thermostat may be bad stuck open or shut. Hope this helps

I have a 1994 toyota camry v6, today my car boiled all the coolant out of the reservoir tank. I had a problem with disapearing coolant a few months back. I flushed the system tightened all the hoses and...

If you have eliminated as a cause:-

- silted up radiator
- fans not running (if they are running the temp sender is OK)
- leaky head gasket putting gasses into the water jacket
- radiator hose going soft and closing up

then that leaves the thermostat being stuck closed. Also if the coolant is disappearing this may still be a hidden leak. The V6 has a joint under the inlet manifold which is prone to leaking coolant, and on a hot motor the water disappears quickly.

Symptoms of a cracked head

First of all, don't "disable" the thermostat, It is an important part of the cooling system. Without it, you could crack the cylinder head from coolant boil-over! Ok, the most obvious sign of a cracked/warped head, or gasket failure is white smoke at the tail pipe, air bubbles in the cooling resivoir, milky, thick, coffee with cream colored oil, or external coolant leaks. If you just have an overheating problem, you should investigate the cooling system first. Check the fan(s), there may be a belt driven and an electric fan for your truck, make sure they both are operating. (turn the ac on with the engine warmed up) Check that when at operating temperature, shut the engine off and make sure the belt driven fan has resistance when you turn it by hand. If it turns and spins freely, replace it. Flush your radiator with a good coolant flush chemical and follow the directions. When flushing, look for water flow in the radiator cap. Replace that thermostat with a new one! replace the coolant cap also. Check for debris on the radiator fins like leaves, plastic bags, mud and bugs.

A flush and a thermostat is never a bad idea, but it sound like your radiator cap is worn out, not holding pressure, replace it, should have a 16 lbs rating radiator cap.

Coolant bubbling in resevoir

I assume the coolant is not actually boiling and that the coolant is bubbling even when the engine is relatively cold. If so this would indicate a blown head gasket. Exhaust gases are escaping from a cylinder into the coolant passageways at the head gasket junction

Can I use standard anti-freeze or must I use GM product?

Keep in mind that there are some things you wouldn't want to substitute on your car when it comes to fluids and maintenance but you should be safe to use an aftermarket anti-freeze. Most anti-freeze is a form of alcohol since the boiling and freezing points of alcohol is much higher and lower than plain tap water.

Over heating and boiling sounds when you shut the

Hello chris_rus968: My name is Roger and I Will help you. The problem could be any of the above plus others. Start by filling the coolant system while the engine is cold. DO NOT DO THIS ON A HOT ENGINE. After the radiator is full leave the cap off and Start the engine. Does the coolant blow out of the radiator? By this it will be the instant the engine starts. If it does you have a serous internal problem. If it does not blow out the coolant put the cap on.Check for any coolant leak you might see.If the coolant was rusty colored I would suspect a damaged water pump.Let the engine warm up if you see no leaks. Observe the coolant fan they should come on around 112 degree FF .If not the problem could be the fan or the temperature switch. As you can see there are a lot of things that can cause a problem. Try some or all of these. Should you need further help please just ask. Thank You for using Fix Ya. Roger

A common problem with overheating that get's overlooked, is a sticking thermostat. As inexpensive as it is, and as easy as it is to replace, I would strongly suggest replacing it. An overheated engine could be catastrophic and a huge expense. I hope your problem is resolved...
