on 82 and 83 rx7 radiators, is there a radiator cap on the radiator or ....? What Im really asking is, is this a sealed radiator, where you have an in and out for water hoses and thats it.

Another guy with a rotary bug has no pictures of his radiator setup, Ive looked on ebay to see if I can get some good pictures, but figured I would post ANOTHER ? regarding this. I figure, if my engine and radiator are from the same year, then I should have no trouble with cooling.

My newer Vw radiator leaks out of the top cap and doesnt hold pressure.

 

they have a cap.

 

The 1st gen normally has a presure cap on the radiator for filling and ETC, the 2ed gens radiator is a 'sealed' unit with an in-line filler neck/presure cap setup.

 

Ooooh then Im after a 86-91 radiator then? I have that 2nd gen filler cap!

 

Well, I have done some searching and I seen some pictures of some radiators, none which look sealed. I searched the 2nd gens, and a guy tonight at a pool hall I go to said Fieros have sealed radiators, and I looked at some pictures and it looks like it has a radiator cap provision. Any got a few cars they can think of that have sealed radiators in them? Im about to weld a radiator cap hole CLOSED...lol..if mine werent plastic on the sides, I would weld it close as well. Anyone got an idea how to close off a radiator cap hole that is made of a hard plastic? The core is aluminum. Thanks

 

Maybe put something in the hole to fill the gap and then possibly use JB weld or other simialar type of thing.

 

on my 2ed gen there is no cap on the radiator. there is a upper hose and a lower hose and thats it on the aluminum and plastic radiator. it's an s4 car.
