Thread: reservoir cap 89 efi rangie

Hello everyone .
My 89 3.5 efi rangie expansion tank cap has today broken . Im confused which cap to purchase for replacement as most recovery systems I know of have the cap discharging into the overflow tank where this rangie tank is plumbed straight into system pressure via the bottom radiator hose . Is the proper cap for replacement a 16lb recovery cap or 16lb non recovery type of cap .

I used a recovery type, stops the system vacuuming and means it pressurises a bit easier and pumps bubbles out faster because of that. I'll post back when I get it sorted out, mine is currently in two bits but still sealing.

Exactly what happened to mine . Broke into 2 bits . I bought a replacement (recovery type) at my local auto supplier this afternoon . Measured dimensions with verniers and all is good . $13.50 and Im right again until the next problem arises .
