SOURCE: engine overheat

Hi and welcome to FixYa,

Offhand it would appear that the radiator fan is not working. In some versions, either the A/C or the heater must be turned on for the radiator fan to work. In some other incidents, the fan utilizes a clutch. Common design makes use of the inverse property of silica oil to serve as the clutch. Still others have a relay that actually does the switching on of the fan. Of course it would be to your advantage to likewise check the temperature sensor on the radiator.

Good luck and Thank you for using FixYa. Happy Holidays.

SOURCE: white tail smoke, both temp gauges (oil/engine)

Alright there your on the money there. A4 audi's and The 2liter golfs do haed gaskets at around 145-150,000 miles. the oil's foamy kinda yellowie cream. Tip for ya When you do the head gasket cahnge the rad and water pump at the same time. Mine didthe same it's costly but worth it for piece of mind, Plus is the only time you get to the water pump apart from changing the timing belt.

My Honda CRV 97 radiator does not have any leakage


check for coolant leak on and around the engine. it could be a water pump, frost plug, heater hose, head gasket. is there water in the oil if so this is an indication of a bad head gasket crack cylinder head or block.

Check the cooling fan, thermostat or radiator. I'd start with the basics and check to make sure cooling fans kick on. If they do, remove the thermostat and recheck. If it still fails and bottom and lower radiator hoses are hot then you have a plugged radiator

The car was overheating i checked all hoses and replaced the thermostat the radiator it still is ovrheating and the water is boiling in the overflow tank


Answer could be a faulty thermostat,or it could be a sign that your head gasket is about to blow ,or last of all your timing could be out of sync.

Answer 2 from Inventus: It means your cooling system is funtioning properly. In a system having a coolant recovery tank, coolant in the radiator is always up to the brim, hot or cold. There is negligible or no air space. When coolant in the radiator expands sufficiently due to warming from the engine, it will squeeze past the pressure cap's bottom seal and flow into the recovery tank. (If no provision for such expansion was present, the expansion would rupture the radiator or your hoses.) Only coolant within the radiator is under pressure, and because of this pressure (together with the elevated boiling point that the "anti-freeze" permits), it normally does not boil. But once past the pressure cap's bottom seal, the overflow is at atmospheric pressure and therefore boils.
This boiling is usually unnoticed after a short, i.e., local, trip because the cooler coolant already in the recovery tank quenches it. But after some highway driving the influx of more hot overflow heats up all the coolant in the recovery tank to the (unpressurized, i.e., "natural") boiling point.
As the engine cools when shut off, the contracting coolant in the radiator sucks back coolant from the recovery tank. Fluid in the recovery tank should never be below the "full hot" or "full cold" marks, lest air be sucked in.
-- BETTER ANSWER ==
Your cooling fans are not turning on. It is not normal for your overflow tank to boil like that. It is true that your radiator is overflowing into the reserve tank, but that means yourr adiaotor is boiling. Check for blown fuses or relays for your cooling fans. IF theya re fine. run your engine for about 15 minutes and drive. When you temp level is at normal operating temp open your hood with the engine runing and see if your fans are on. If they are, then you may have a bad thermostat or a plugged radiator, or a bad water pump. If the fans are not on, get your cooling fan switch replaced if your car has one. Check your temp sending sensor

I have a 1986 Corvette Coupe. It overheated today when I sat through 5 or 6 lights or 20 minutes.. Smoke came out of the hood. The coolant overflow sprayed out radiator fluid I think. The temp went to 291....


Let it run for about 10-15 minutes after it cools down. After the 10-15 minutes (but don't let it overheat) squeeze the top hose to see it it's hard. If it is, it's probably the thermostat, and the coolant isn't flowing through the engine to the radiator. It's just staying in the engine and getting hot.

Van is losing water but the overflows continues to stay full. No cracks in radiator and the cap where you put in the water has a hose going in but no hose on the opposite opening.


In a properly working system, the coolant expands as the coolant temp rises. The excess coolant flows into the overflow container by the hose that runs from the bottom of the overflow to the top of the radiator, under the radiator cap. When the coolant begins to cool down, it contracts,drawing fluid back into the radiator from the overflow. The water pump has a "weep" hole located near the bottom of the pump housing that will leak coolant if the pump is going bad. In some engines, the 3.0, the water pump is located under the camshaft timing belt cover, and is a BEAR to deal with. However, the coolant should be pulled into the radiator when the engine cools, so check that the hose from the top of the radiator is attached to the bottom of the overflow and that it is not blocked or pinched. Have the system pressure tested to verify that it has no leaks. Hope this helps. Dano

My coolant expansion tank is overflowing after 20 minutes running


There could be a couple of reasons for this,

1. The thermostat could be stuck closed creating more pressure than normal. Your temp guage would show a higher temperature or you have another blockage in the system.
2. The expansion tank is too full.
3. The cylinder head may be leaking. If you fill the system run the engine to normal temperature with the radiator cap off, look for quite large bubbles coming out of the filler cap. If the head is badly leaking, they can be like a volcano. The temp will rise quickly from cold and the engine will overheat in a short distance.
It does seem odd that it would only spill over after 20 mins. Suspect that the expansion is over full first if your temp is normal. Let it run until it stops and see where the level is when the engine is cold.

My 91 Chevy s 10 Blazer over heats in addition to check gauges light coming on what could be the problem?


There are 4 things you want to check in this order.
1. Make sure your fluid level is up to specifications.
2. Make sure the fluid is travelling through the radiator freely(water pump).
3. Make sure your thermostat is opening. This requires a great deal of caution, leave the radiator cap open (if it has one) and run the engine until the top radiator hose gets hot, If you have no radiator cap, watch for water rising or dropping in the overflow tank.Also watch for bubbles within the overflow or radiator.Also put all temp controls on high on the climate control center and feel for hot air once the engine reaches operating temperature(185-200 degrees). If you don't get heat within the regular time slot of 10-15 minutes you will need a new thermostat.
4. If you discover a large amount of bubbles within the radiator or the overflow tank than you've got a headgasket situation and should not drive the vehicle until necessary repairs are made. Thank you, Dana

Chevy S10 overheated, now heat doesn't work, leaking coolant


When an engine is overheating and then the temp drops on the guage, it's usually a sign that the coolant is not touching the temp sensor. There's no coolant in the engine. Putting water in the overflow tank won't solve this. Take the radiator cap off after the engine cools and put coolant in the radiator. you might have to crank the engine and do this several times, as the engine can develop air pockets that won't allow the coolant to travel inside the engine. If you don't see any leaks, and it still uses coolant, you've probably got a blown head gasket. Check for water on the plugs, check cylinder compression. If it slowly uses coolant, try putting a large box of pepper in the radiator or some of that radiator seal copper flakes.
