Every. Damned. Radiator. Cap. I can find for sale is a motorad. I've gotten two now that came in different brand boxes, neither will hold much pressure or draw in coolant when the engine cools off. I'm seriously doubting how much longer I can deal with every new part being fucking garbage.
Cons: poor sealing, no pressure, cracked rubber
I had a Motorad radiator cap until about a week ago. Worked fine just changed it for a spiffy Flex a Lite cap.
Pros: worked fine
