whats up with replacing the rad cap cheif did you lose it or blow it off ?
didnt the old one have a pressure stamped on it ?

It blew off a while ago it got changed but i never checked what pressure the cap was. I never ever found out what pressure it was supposed to be. I just wanted to check before i took the truck for a run.

It didn't actually blow off, It fell off after i had taken it to a Rad place to clean out my Radiator and someone didn't put it back on properly. I learnt something from it, always check things before leaving a garage.
