92 Toyota pickup 3.0V6 EFI Overheating problems- Help troubleshoot!

* I also posted this in the newb forum, hopefully you wont get a rag for me posting this here but I was hoping this might yeild more quality answers posting here.*


Im in cold weather. Alaska. Its about 10 degs over the time this started.

Problems started: I was doing some maintenance yesterday and notice the coolant was low so I filled it up. It wasn't bone dry but low. Filled it and didn't think much of it. Later that night.. I discovered the problem. I started the truck and let it warm up while I was inside and not paying attention to it. roughly 30 mins. Came out to a puddle of coolant and a real hot engine with a bit of smoke coming off of it, not full on, but a bit.

This problem also recently started after I had the truck in for some new tires and an oil change (normally do it myself but it was friggin cold and I don't have a garage).

High initial idle. This morning (cold so normalish)

Over heats quickly: Started it this morning to get it to a friends house to work on it but after a less than 5min idle started driving around the block and by the time I got back it overheated.. less than 10 min over all. Stopped and turned engine off. After cooling a bit I restarted and watched the thermostat. It started and sounded fine at about a normal operating temp and within an minute or two the temp spiked rapidly.

No oil in coolant.

Some more truck history: 215K miles. Bought in fall near Seattle drove from there to san deigo. Then in November drove back up to anchorage without a hitch through som negative 50 degree weather.

I was talking with my friend trying to troubleshoot. We think its not any or the real easy fixes like the thermostat or radiator cap and could most likely be a leak in the head gasket (exhaust into coolant?) or possibly the water pump?.

Not too sure and would like to get the best diagnosis before deciding what to do. Your feedback is appreciated.

Ok so my last 3.0 was having some over heating issues that you have described. And also had a high initial idle. But after driving for 10 min or so would over heat so i decided to not drive it. Next time i fired it up and took it on a drive the headgasket blew all the way through and dumped oil into my coolant system and coolant into the exhaust. So As of right now it sounds to me like you have a bad headgasket. Although I'm curious were this leak is coming from that you stated was causing the puddle. And the cause could possibly be as simple add replacing your radiator cap. Since you could be losing pressure in your system. Also would be caused by a leak. / headgasket.

I did not find any leak. I think it may have come out the over flow, after it had been hot for a bit. The puddle was right below the coolant tank.

This morning when I started it up and drove a short distance the were no leaks or puddles

In which case the radiator cap may be bad? But also the head gasket may be going getting worse?

Would any of you suggest one of those head gasket stop leak additives? Ive heard some negatives that they are not that good for the engine and don't really work.

Wouldn't suggest the stop gap stuff, but sometimes it does work, sometimes it makes everything worse.

I was recommended to do an engine block test to see if exhaust gas is in the radiator and it failed. So it looks like the head gasket will be replaced.

Is there any other gaskets/seals/parts I should be looking to replace as well?

The engine has a small oil leak too. I'm not sure exactly where yet but Ill check it out and see if its worth my trouble to fix. This will be my first head gasket replacement/ engine tear down and I figure I should replace anything the is worth replacing. Any tips would be much appreciated.

I stopped by Napa and am going to price out Oriley too for head gasket kit. The full engine gasket kit from napa is 270$. Is this a good product to go with or should I look for something else?

Thanks everyone for your advice.
