My truck is a 1990 pickup with a 22RE. The radiator is a GM; I'm not sure of the details. I was wanting to make sure I have the correct radiator cap, in terms of PSI. Stock specs are 13 PSI. Does anyone know how many PSI my cap is rated for? Here is a photo:



All it says on it is 0.9.

Thanks,
Josh

 

.9 Bar is equal to 13 lbs per sq in., Perhaps it is a measurement in Bar?

 

Your right, because 1 bar = 14.5038 psi

 

Perfect, thanks!

 

Both my toyotas came with 0.9 caps, should be perfect

 

Ok good, thanks
