I have a 1995 4runner with the v6 3vze motor when I bought it, it was over heating, so I replaced the thermostat and sealed the headgasket and now it it over heating worse than what it was I know I need to flush the system but if that doesn't work what could my problem be. Thanks in advance for any advise

 

what do you mean by "seal the headgasket"? If your head gasket is blown you replace it, you can't reuse them.

If you haven't flushed the system properly, chances are you have air bubbles which are causing overheating. Also, if you did reuse your headgasket, chances are its leaking like a sieve.

 

How did you seal the head gasket? Use one of those head-gasket-in-a-bottle repair things? If so your radiator might be all clogged up.

 

I did use the head gasket in a bottle repairs and it worked great... how do I get all the air out of my system

 

And what's the best way to unclog my radiator

 

The headgasket repair in a bottle is no repair. It has likely clogged your radiator as tardman91 says and you have put a temporary band-aid on the HG leak. A quick search here will lead you in the right direction......

 

A quick search were and thanks for all the info

 

The only way to fix a blown headgasket is to replace it. Use the search function



there are a few write ups for the 3.0 head gasket replacement as its a common problem.

 

+1 for rworegon.
your headgasket it shot. A band aid on a gun shot wound aint gonna cut. I wish it was that easy. I just went thru the HG issue myself a few months ago.

Congratulations! You've now TEMPORARILY repaired your Head Gasket problem in exchange for one new radiator~

 

The main reason I do not think its my head gasket is because my oil has no water in it at all... my clutch fan was shot just replaced it doesn't overheat as bad still does a little bit tho and I've flushed my radiator what else could be causing the over heating and is water in my oil what other signs are there to diagnose a head blown head gasket

 

oil and coolant dont necessarily have to be mixing for ur hg to be gone. i would do a compression test, if theres any liquid sitting in ur exhaust tip dip some white paper in it to see if its coolant. also ur exhaust gases may smell sweet. as for your rad id take it off, law it down with hose ports facing up, fill it with a rad flush chemical, let soak for a couple hours the n blast out the rad with a garden hose
