Another head gasket question
Hello , i'm new to this forum and hope somebody can help me out . I just bought a 1994 ext.cab pickup with the 3.0 and a 5spd. it has 148,000 on it and is having a overheating problem which i was told when i got it , i had to replace the radiator in it along with the thermostat which is what the people i bought it from thought it needed or maybe a waterpump they wern't sure (and neither was i ! ) my first thought was a bad head gasket but there wasn't any water in the oil it seemed good well sat. i got the radiator and t-stat in put in new ant-freeze (also flushed it out ) and stated it up ran for maybe 5 to 10mins and went right to the redline and started to boilover , i did run it with the cap off and heater on to try and get the air out which seemed to work. now the big thing is what is next ? could it be the head gaskets ? or maybe the waterpump ? is there some way to find out if its the head gaskets or not ? i have no clue as to really what was ever done to this truck , i did see on a sticker that the timeing belt had been changed at 108,000 i think it said when they did that would they have checked anything else out ? is and was there ever a recall on the head gaskets on these motors ? and if it is the head gasket what brand would you guys recommend ? or is this something toyota would repair ? also i'm on a budget a very low one which i spent pretty much already so any help you guys can give would be great !

When your trying to figure out an overheating problem the last thing you want to look at is the headgasket. Judging from what you told me possible crappy t-stat you got. What you need to do is go to toyota and buy an OEM t-stat to make sure its working properly. Alot of wallbobs t-stats are garbage off the shelf.... Is it leaking anywhere? If its not major leaking anywhere then you need to check internals. Is it consuming coolant? Alot of times with the 3.0 if the head gasket does go out its externally from the cylinder which means look outside the head around the block for coolant leaking..... 3.0s have had head gasket recalls way back in the day due to lots of reasons but for the most part don't worry about that. if the water pumps bad you will prolly here it grinding and making a god awfull screeching noise.... and or leaking down near the timing cover and crank...... check hoses.....

You could run it without the thermostat but if you are living in Vermont I imagine your gonna want your heat soon if not already. Did you get a toyota thermostat? Does it run rough and are you getting any white smoke out of the exhaust? If so, does it smell like coolant. As to the timing belt job at 108K I would think anyone who's smart enough to replace a timing belt would also do a water pump on one of these engines since the pump runs off the timing belt. Who knows though.

take out the t-stat then you can at least rule that out. Get one of those cooling system leak down testers that you plug into the radiator before you tear into the heads. but since it's a 3.0 there is definitely a strong possibility it's the head gaskets

the head gasket recall doesn't have a time limit. If it hasn't been done and the truck qualifies they will still honor it to the best of my knowledge

that would be crazy man, because just yesterday my truck started blowing out massive amounts of white smoke from the muffler and from what ive been reading its probably the head gasket... time to give toyota a call i guess.

From experience I owning a 93 4 runner v6 at one time.
If someone recently did a head gasket job on it is possible they put the head gaskets on wrong. You can confuse the right and left bank if you do and put it all together it will overheat every time.
Don't keep running it like that because your gonna burn up your rod end bearings quick.

Another novice mechanic- expert parts replacer here. But am a helo pilot and when our 4bangers start to over heat alot of the time it's running too lean. Could his fuel system me off? clogged injector?

try w/out the tstat, didnt catch if its a new radiator but if its old check if the fan(clutchfan) is blowing hot air when the engine starts getting hot, if the air isnt hot and the water is flowing then ou might have a clogged radiator. you didnt mention if your losing water, are you?

I have no clue if anybody has replaced the gaskets on it i just got the truck on the 22nd i did see on the fan shroud there was a stick that said they had replaced the timing belt at i think 108,000 its got 140 something on it now , and yup bran new radiator in it .the water seem to be flowing but for the fan i'm going to have to try it again i really can't remeber if it was turning or not i as i said in 10mins it was boiling out and don't know if i said before or not but we had the heat on full and as hot as it got there was not even any warm air coming out of the vents . kind of had to say about loosing water i don't think so can't see any leaks at least not till it starts to boil over !

Do a cooling system pressure test it will tell you if it's the head gasket for sure or not. You plug it into the top of the radiator and if it builds up pressure and holds the head gasket is good. If it builds up then goes down when warm you have a leak somewhere.
Me personally, I love Toyota's but I stay away from 3.0's these days because of the head gasket issue. I've had three and they've all been problematic in one form or another. The 22re on the other hand is bulletproof. Good luck man your head gaskets are probably blown.
