SOURCE: over heating

with a 1993 you do not want to run it with out the thermostat it will damage the engine but you might want to try getting a low temp thermostat from advance auto parts and try that

SOURCE: still losing coolant

Hi, Sounds like the water pump is not circulating the water, as soon as the engine heats what water is in it, it will boil. Since you are brave enough to open the radiator when it is hot ( Bad Idea ! ) open it when it is cold, start the car and watch to see if the coolant circulates. You may have to wait unit the thermostat opens and if the water pump is bad when the thermostat opens it may spray hot coolant and steam instead of circulating what is in the radiator so don't be in the way. Not the best way to test this but works if you don't have diagnostic tools. Good Luck! By the way, coolant means antifreeze mixture which if it gets too thin lowers the boiling point significantly.

SOURCE: radiator keeps over pressuring out of cap

I hate to tell you but most likely your head gasket is blown. But first have your 13 psi cap pressure tested. If the head gasket has blown out in between the cylinder and the water passage , engine compression will enter your coolant and over pressurize the cooling system. This could be caused by a pin hole in the head gasket and that is all. also make sure your head is not warped. The 22re has a cast iron block and aluminum head causing the head to expand at a different rate than the block. causing the gasket to wear and leak. Good luck.

it is the head gasket blown from the cyl to the water jacket ,a radiator specialist can test for combustion gases in the water to confirm this ,but that is what it is . "youdoit"

Coolant overflowing through expansion tank when engine becomes hot, after running about 20km


if thermostat is new and not in backward?
then its bad head gasket
there are 2 tools to find this.
1: Rad leak down test tool
2: and the rad cap, green/blue dye test for exhuast

Van overheating


Pushing coolant into the reservoir is a symptom of a bad head gasket. Have the coolant check for combustion gasses. Easy test.

Steam from coolant tank


Rad cap pressure determines boiling point,as well as coolant strength.. if the system is pressurizing immediatly after starting, i would suggest getting a "block test" using fluid that reacts to combustion gasses for possible head gasket or other issue

1992 80 series land cruiser 1hdt pushing coolant back into over flow bottle had pressure test which was all good new cap and new thermostat but still with problem


Just two possibilities. First would be the air wasn't purged completely out of the system. Second is a blown head gasket. And yes, I have seen a good pressure test on the coolant side (15 to 18 PSI). But the pistons throw out 100+ PSI. Check or have checked, the coolant system for exhaust gas. There is a test for it.

Just a guess but I think their diagnosis was that the head and head gasket was not leaking and not a source of the bubbles you spoke of.
Usually when the head or head gasket is leaking, a unusual amount of water will will be expelled from the tail pipe.

You had the heads pressure tested? Did they do a compression test or a leak down cylinder test. It is possible to have an exhuast leak through the head gasket into a coolant jacket and push coolant out throught the overflow. A very small crack in the cylinder or head can do the same thing, and you wouldnt necessarily see any oil in the coolant. You can buy an inexpensive radiator pressure tester, hook it up and pressurize the cooling system to the pressure listed on the cap. Start the car and see if it gains pressure that is not consistant with the coolant warming up. Another test is to hook a hose to the overflow directly off the radiator. make sure the radiator cap is tight and put the other end in a bottle with water in it. If you see a stream of air bubbles which quit when you turn the car off, then you have exhaust gas pressurizing the cooling system.

Where Does The Overflow Tank Hose Connect


to weaker mixture will cause vehicle to overheat ,but i think that the radiator cap rubber has perished causing the coolant to throw out or the head gasket ,get the cooling system pressure tested ,and then run engine with gauge attached to check for excessive pressure build up ,(head gasket test) ,another trick is to fit a bottle to end of the overflow pipe so what goes out gets sucked back in when engine cools .Check the rubber seal in teh rad cap and check the seating that it pushes and closes onto.As for the sliding doors use your judgement and you will not go far wrong

Overheating, guage not over 1/2 mark, overflow smells like exhast


Have you tried running car from cold, with rad cap off, & heater turned on, coolant topped up, an inch or 2 from top of rad? Let it run up to operating temperature, cooling fans kick in & out 2 or 3 times, and top up coolant as needed, then put rad cap back on, & fill return bottle up to mark. There may be a worse problem, but bleeding system as I have described, ensures all air out of heater core & cooling system, which has been cause many times before on all makes & models of vehicles. Especially when no heat situation. Let me know if it helps.

2002 pt cruiser overheating was told i need a new raditor and thermostat for 1 grand sounds fishy


Flush rad & change coolant & thermostat. Check operation of rad fan, & make sure it is coming on when engine reaches normal operating temperature. Be sure to bleed air out good when refilling rad/cooling system. Start engine & turn heater on when refilling & let rad fan come on & off at least 2 or 3 times before putting cap back on rad, and refill rad as needed as you do this. then fill return bottle to proper level & see what happens.
