I am afraid it is, or a blown water jacket either way the heads need to be pulled and checked make sure they are not warped. It's best to have the heads reworked it's safer, then you know your heads are OK if a good machine shop did the job.

I have just water coming out of the tailpipe and it will keep dying once it warms up?


You most likely have a really clogged CAT or a blown headgasket.. being the fact it runs ok till it's warmed up(fluids thin when warm), I would lean more towards the headgasket.. check your spark plugs for any oil or fluid on the spark end to determine which headgasket is blown.

The car idle in park for hours,but when drive at high rpm it heats up after a few miles and then smoke come from the exhaust?


Have the coolant checked for hydrocarbons. It sounds like a blown head gasket, but from the cylinder into the water jacket. Under higher pressure the engine heat/exhaust gases will enter into the coolant and pressurize and overheat the system. Then with the additional pressure, water vapor will bleed back into the cylinders and burn off as white smoke. This doesn't seem like a fully blown gasket, but one that has a tiny leak under higher pressure and heat conditions. It will eventually get worse.

How do I stop my 01 explorer from 0ver heating. I already replaced water pump thermostat and radiator


Since you have done the basics, more information is needed. Under what conditions does it overheat, and how severely? Only when at idle for several minutes? Could be bad fan clutch or missing/damaged fan shroud. Severely overheats so bad you can't drive it at all? Blown head gasket? You can often diagnosis this by running with radiator cap removed and see bubbles in the radiator, or also look for water in oil, or oil in the coolant. Also, check with parts store. I think certain years of these run a reverse direction water pump, and if you get the wrong one they will overheat badly.

Oil leak


Check your oil pan, did you run over something? That many quarts of oil has to be leaking from somewhere. Headgasket blown would likely show as water mixing with engine oil(no loss of water would likely remove likelihood of blown headgasket).

Overheats. runs fine when idiling.holding the fan off, and a/c on still cant make it overheat but once driving for 5 mins starts to overheat. replaced thermostat, water pump looks to be fine. cleaned rad....


Water pump. The impeller will slip on the shaft. As you said runs fine at idle, but when you run it harder the impeller doesn't spin fast enough (slips). Causing it to over heat. replaced to many for this problem. Also The pumps that have the metal impellers will be tight when cold, don't let this fool you. when they heat up they slip.

1990 Honda Civic low kms. overheated, added


I want you to take a couple of spark plugs out and examine them. If you find Anti-freeze on them then you may have a blown headgasket. A very common problem of driving a car until it overheats. I really do hope im wrong. Since it is an overhead valve engine with the cam shaft above...its a 1000.00 to 1500.00 dollar job to have it properly repaired. From here out im just going to explain why this happens...
When a car overheats - be it a faulty thermostat...low coolant...or a faulty water pump or improper coolant mixture ratio. The engine gets so hot that it actually makes the top of the engine change shape... it actually changes enough to damage the head gasket. The head gasket keeps the explosion inside the combustion chamber. Keeps the water in its coolant jacket. and keeps the oil inside its ports. When the Headgasket fails. Sometimes coolant gets into the oil (makes a milky residue form on the inside of the oil filler cap...or makes the engine oil look like chocolate milk.) or oil gets into the coolant (makes your coolant have an oil slick on top) It can also cause water to get into the combustion chamber and when the engine is running - blast the combustion back into the coolant (causes the coolant overflow to overflow or spray) or oil gets into the combustion chamber causing the plugs to get fouled (dirty). worse case...all the above happens. I hope this helps in figuring this problem out...i really do hope im wrong about a blown headgasket . As even i tremble in fear of it happening to my car. Good Luck!

91 toyota 4x4 22re overheats on highway, but not at idle.


original issue sounded like thermostat but now that you have lost power i would have to say thermostat, blown head gasket, and warped head

to check thermostat find and remove place in pot of boiling water the see if it opens, then to ice water to check if closes.


the only way i know to check headgasket and head is to check oil and water. oil will have water in it, and water iw have oil in it
