I just had my radiator fixed - the fixed a couple of seams that were leaking. I have a 20PSI plus cap on the radiator. The guys at the shop told me to buy a 13PSI radiator cap. I have a 1993 Ford E-350 460 V8.
I'm looking online- there is a quite a few that will fit my make and model but there seems to a difference with Cap Depth . Any thoughts or recommendations.
Side note they said my leaks were probably caused by having the 20PSI cap on. BTW this is a 2 year old radiator.
Your LD should is supposed to have a 13-lb cap. 20-lbs is way too high.
Remove the radiator cap, take it to Napa and have them match it, with a 13-lb cap.

Thank you Larry for your reply. I am on it. I will get a new 13PSI cap. Please keep replying to questions on the forum. It really helps us- non mechanical guys. We need reassurance.
