nothing to listen for. I've seen trucks with completely blown HGs that guys have driven for WEEKS before they took the time to fix them.

However look for coolant burning in the exhaust. White haze, steam, even a coolant smell from the exhaust.

Look over the truck as close as possible and make sure you don't have a leak somewhere. Go to the carwash and wash the engine compartment very well, spray it down with degreaser and wash it again. Then watch for coolant "trails" over the next few days or week. Also there is a dye made to help find leaks, you should be able to get it at any auto parts store.

completely forgot about the dye, thanks for the reminder.....

 

The exhuast is nice and black and dry, lots of black and a little bit of blue and a puff of white in the morning is all I get smoke wise. There is a coolant smell some times when I pull in and am about to shut off the truck I smell it a little bit but maybe onece or twice Ive smelt it. Ill go over it truck again tommorow looking for leaks.

how do I boil the cap?

 

If you have a coolant smell then it is eaither leaking into a cylinder, out the side of the head onto the exhaust(which is tough because the manifold is higher than the head's sealing surface), or coming from the heater hoses or fittings onto the exhaust.

The cap is held closed by spring pressure. I've never heard of boiling the Rad Cap.

I've boiled plenty of thermostats though.

So I ran the truck hard today on the way home from school and I did 80 on the highway, got home noticed alil bit of coolant in the wheelwell and on the frame rail so I figured that the reserve tank over flowed, poped the hood and it was all dry around the tank cap and hoses, long story short I traced it up to the headgasket leaking just a little bit right under the T stat housing. You can see where the previous owner put some sealer or glue of somesort on it to stop the leak and a part of it came off and started leaking again.

Im in no position to afford putting a new headgasket in right now and I know I need to get in there and fix it and get R done right but I just cant right now and I have to drive the truck. Is there and temporary fix I can do to stop it or am I going to hurt something or should I just let her bleed?

Ive see that radiator stop leak stuff in the autoparts store does that work? or should I put sealer over it again for now?
