My anti freeze level keeps dropping about a half a gal per day. I cannot find any leaks, it doesn't smoke it doesn't smell like anti freeze and it gets good heat. Any ideas? Clint

 

If there is nothing showing on the outside of the engine or on the ground, check your oil level and appearance to see if it's going into the crankcase.

 

i did oil level is good and its notmilky either

 

Then it must have an external leak somewhere.

 

whats the best way to find it? we put 25 lbs of pressure in the cooling system and it didn't show anything

 

I slowly lost ALOT out of the water pump weephole. And NEVER smelled any of it. Check it out.

 

If you are sure that there is no external leaks, I would venture a guess that a head gasket is leaking coolant into the combustion chamber and out the exhaust. A small leak may not cause smoke from the exhaust. Run a compression test.

 

as much as it's losing per day, it seems like it should be a bigger leak than a small leak from the head gasket. half a gallon in 30 miles it should miss or run rough shouldn't it? the blazer runs good no missing, knocking or any other signs of a head leaking

 

Ok, dismiss what I have said. Your choice. I'll just keep out if my opinion is not wanted. Maybe you have a magic block?... It has to be going somewhere.

 

i'm not ignoring your opinion, I asked for help, all i'm saying is, losing all that it just seems like it should show somewhere and I can't find anything, anywhere and i've had head gaskets leak and the vehicle didn't run very good, even when it was losing alot less than this is.
