losing coolant?
Hey all,
need a little help, got a 65 with a newly rebuilt 250 and a new 3 row rad. from advance and a new heater core. Now here's the kicker, I have no visible leaks of anti-freeze any where, I have even put large sheets of card board under my truck. and nothing but I am losing a good bit of coolant, maybe a half gal. ever 75-100 miles, now I don't drive the truck a lot, sat. mornings to starbucks with the wife and church on sun. and just short runs to the store maybe 25 miles a week so it does take 3 or for weeks to lose the coolant. Any ideas? I am guessing head gasket but no coolant in the oil or vise-versa, and before I take off the head thought I check with the pros, so any help is greatful Thanks Mike |

Re: losing coolant?
The coolant can also go out the exhaust pipe....let it sit for a few days and then watch the tailpipe when you start it......blown head gasket can send the cooland in 2 different directions.

Re: losing coolant?
I agree with 72freak; its got to be going thru the exhaust. Internal leak somewhere. If your exhaust is really white, like steam, its getting burnt in the combustion chamber.

Re: losing coolant?
And also. If it is going through the exaust, after you pull the head the one it has been going through will have the cleanest piston.

Re: losing coolant?
I agree with the prior posts, I would get a pressure tester and test the system, Then fire up your rig and watch the exhaust for white smoke and antifreeze. good luck
