no park on a slight grade and crack the cap on the radiator while it is running. Dont open it after youve driven it though. let it cool.

I had this same problem and the coolant in the jug was full. when I ran itand got the air out, I wound up putting a whole jug of coolant in.
And my real problem was I had a leak by my thermostat that I couldnt see. It dripped down the front of the motor and burnt before it hit the ground. Very common with the 360 and 318.

 

ive hear this almost daily as well, and sounds easy enough to fix....... but as long as im not TOO low on coolant it wont hurt the truck to wait a little while till i get time, ill it?

 

I've filled mine up 3 or 4 times now wafter draining it to get to crap and have never had air in the system. What I so it let it cool down all the way and pop that cap off. Then turn the truck on and let it idle. I usually give it some gas with with my hand on the TB. Your trying to get it to warm up. It'll take a few minutes and it might start to overflow just a little bit. Once it warms up the thermostat will open up a bit and you'll see that coolant in the rad drop really quick, so filler it up untill it can't take anymore. Rev it up a bit too, that makes the coolant drop. Cram it full and put that cap on.

Never had a problem doing it like this.

i ran across it, and noticed it was a who's who of the past....

IndyRam, Mason, Bill, Hank, God, Socha, Muddy Blue, and Habeb.

Does anyone know what ever happened to Muddy Blue ? He came down here to N. Ga college, signed up into the service, and disappeared.
