So my 91 car has a PWR radiator. It's a nice radiator, but the cap is not the same as what I find listed for a 91. The PWR radiator requires a "Type 1" cap. See this link and look at the picture: http://www.driftmotion.com/591-A001-p/dm1061.htm

Is there an OEM pressure cap that is "Type 1"? I have a couple OEM caps on hand and they're all Type 2. I want a new cap (existing one is old and the seal is not perfect and do not want a high pressure cap. I'd like my system to stay at OEM pressure levels (88kPa) until I can get to my rebuild.

Another oddity about this PWR radiator is that the overflow outlet is too small for the OEM hose. I'll either need to find a special reducer hose or use some adapter. Far from ideal...

Anyone have any input?
