This cap for perfect I was worried because the one on my truck had 4 hand groves and this had 3 it appeared to be a bit smaller then what I removed but it fit perfectly I spend a lot of money buying coolent pressure tester and adapter set and the cap was my reason for burning so much coolent I would highly recommend this cap before going to a shop or dealer for parts or diagnose

Love that it costs about $10! Bought one from Peterbilt parts dealer and they charged me $75+ for it and it cracked in less than 3 months. I bought 3 of these from Amazon just in case I lose one or can help a fellow trucker out. It seems to fit several truck models and years.
