I need to buy new radiator for my Trans Am GTA 1988 5.7, but I don't know, do I have to buy radiator cap adapter or not?

On the pictures below, you can see radiators and radiator cap adapter.

I know that I need radiator cap, but do I need radiator cap adapter too?

Thank you in advance.

Best regards!

 

Are you buying a stock replacement radiator? If so you won't need an adapter for the radiator but you should still buy a new radiator cap just to be on the safe side.

 

Yes, I buy a stock replacement radiator, but I don't have old one

Previous owner put some radiator form other car (Alfa Romeo ) so I need to change complete radiator.

br!

 

Just find a replacement radiator cap for 1982-1992 Firebirds and Camaros. And it should fit your stock replacement radiator.

 

OK, thanks

 

for like $9 shipped you can get a ricky race Radiator cap. 17 to 20 LBS

i have a new one in the Bag. or. you can go get one off Junkbay
