What radiator cap to use with ast elimination
Hi there,

Where can I get a 16lb cap after eliminating ast with 86 fc radiator neck assembly from mazdatrix? i checked the mazda parts catalog, but it doesn't specify pressure.

Thanks

Another question, is there any difference between 86-88 turbo/na waterneck cap? I heard one of them is a non-pressure cap.

It's been a while, but IIRC MALLOY MAZDA sent a .9 bar MAZDA cap with mine. Never been issues.
