Radiator Cap temp? Vp V6

[discostuee]

Hi,
Ive done a engine conversion in my 4runner and used the orig V6 Rad as it all fits well with the engine. My question is what is the supposed temp of the radiator cap as it seems to just spew out all the time it gets warm. It currently has 90 written on the cap thats in it but thinking thats degree C. Ill be buying a new one today and want to get the correct one.

Thanks

I -think- it's measured in kpa, and I think it should be 120 or similar. But I'll go check after breakfast, because I could be talking about anything

yeah 120 sounds right.
The lower pressure cap will allow the water to oil at a lower temp then the v6 needs.
