New Radiator and Losing Coolant

Losing that much coolant due to a blown head gasket or a cracked block, it is going to show up at the tailpipe as tell- tale white smoke and you will be able to smell the anti-freeze burning out. It is an indistinguishable odor.

Two gallons in such a short amount of time especially, is extremely excessive. Since it's not puddling out on the floor it has to be burning off. Hopefully not a cracked block, just the bad head gaskets like has been spoken of here before.
 
I was losing coolant, and I attributed it to it going out the overflow during highway runs. But I found that the water pump would leak only while the engine was both warm and running. Never leaked a drop when you would first start it up, or when you shut it off. The leak was slow enough that it would evaporate on the hot engine block, so I wasn't leaving a trail of coolant. Found it by accident when I left the engine running at a gas stop and opened the hood. It was one of those "leakless" water pumps. Replaced it and coolant loss problem is gone.

If it's "burning" enough water/coolant the plugs and combustion chamber should look nice and clean. Might look slightly different with coolant vs water.

So sounds like the same as the trick of a water misting bottle through the air intake or vacuum port at fast idle.


Thanks, was unsure if results would be the same.
