Question about 1991 Toyota Camry

1 Answer

What causes 1991 toyota camry to over heat? we put a new radiator in it last year cause the radiator got cracked. but it didnt start overheating til this year. so we changed the thermostat thinking it wouldnt do it anymore. it kept overheating so we changed the thermostat again but it wasnt it so we changed the water pump. it still keeps over heating. an we cant figure out why. if we keep the car running when its parked its fine. but once we start driving it it overheats an steams after 10 minutes an overflow is boiling because steam is coming out of the hose from the radiator.

Change the radiator cap, it may be the wrong pressure rating which will cause the coolant to boil at a much lower temperature than designed.

Car won't start, there is gas in the oil. Is there possibly a seal gone bad?

A seal (gasket) failure is one possible cause. Or possibly a cracked intake manifold or even a cracked block. Warping from overheating is a another possibility. Engine will need to be disassembled to determine cause. It's not all doom and gloom. A cylinder compression check may provide you with enough information to see if it is worth attempting a repair before getting into an engine teardown. If it's a top end engine repair, it won't be cheap, but may be worth your while...the key is to understand what caused the engine failure before sinking any serious cash into a 23 year old car.

Radiator toyota camry 1998 v6

You may have

- a coolant leak somewhere, comes out when the engine heats up and pressurises the radiator. Camrys do develop a crack in the plastic radiator top tank, which can be hard to see if on a seam. Another place which leaks is under the intake manifold, which is not visible. There is a test, called a "leak-down" test

- thermostat stuck closed, preventing coolant circulation

- a leak through a head gasket from a combustion chamber to the coolant jacket. This will quickly cause overheating, and sometimes causes white bubbles in the radiator neck, like dry ice. There is a test kit available for gases in the coolant.

My car is over heating

I assume the engine is running correctly.

First make sure the coolant is full and has no leaks.
If you are not sure about leaks , it can be pressure tested. The pressure test may also tell if the head gasket is good.

Replace the thermostat and coolant. Check the fins in the radiator core are not corroded

If it still overheats, you may need a radiator replacement. radiators often only last 8-10 years

Dont drive it overheating, as it will damage the engine and cause it to burn oil and smoke

Car over heats

You may have a clogged radiator or you didnt get all the air out when you filled up the coolant
Its also possible the water pump fan blades are corroded away.
If anyone ever used a stop leak this could cause a blockage anywhere

1991 toyota camry. It has a new radiator and cap,

the a/c when running creates a lot of extra heat and needs second fan, if second fan is not working right this will cause overheating, if fan is creating a load noise it is likely bearing is bad and will not spin as fast as it should not cooling. also check that fan it not hitting anything if you describe loud noise i can give better idea
