Coolant hose is not a "coolant" hose...

[Rawze]

Every truck that has come over here where coolant was drained got a hard vacuum on it to remove air before cranking it. I have seen lawsuit after lawsuit of shops that only fill coolant from the top and do not pull a vacuum on it, then the engine warped a liner a few miles down the road. Nothing to play with in a wet liner engine. Always pull a vacuum to remove all the air then top off.


- I use an old A/C vacuum pump and pull it down to 0 air completely just before that last couple gallons goes in. I have never had to burp one after at all and every drop that came out goes right back in.
