Description
Allstar Performance large style radiator cap, 29-31 lb, round steel with zinc oxide finish. Fits D1 radiators as well as most others used in 600 Micro Sprint applications.
Cap pressure rating is not a detail to guess at. A higher pressure rating raises the boiling point of your coolant, which is exactly what you want in a car that idles hot under caution. Too low a rating and you will push coolant out under load.
Cheap part, and one that quietly fails – the seal hardens and stops holding pressure long before it looks worn out. Replace it every season or two. In stock in Fresno, CA.
