I know that the griffen radiator has no fitting under the filler for the return on the heater core. Now my brother just ordered one for his 82 z. He doesnt need that fitting cause the hose goes to his water pump. What about my 91 Z. How diffrent is it than his, besides it being reverse rotation.

 

yours isn't reverse rotation.

 

huh???


he said his is a 91 Z, it sure is reverse rotation


if your water pump has a plug/port on the top, you can do the same, also, some aftermarket pumps have a port on the top as well

 

Yep. My stock waterpump doesn't have a fitting (I also swapped out to different rad. after mine blew). I have a new stewart to put on and it has the aux. fitting hole on it.

 

He means counter clockwize rotation (serpentine). The V-belts had clockwize rotation.

I thought he meant reverse coolant flow the first time I read it.

 

ah, got it. I just read it wrong I guess.

 

I guess i gotta check under the hood, wish it would stop raining for one day.

 

took a look at the pump today. no fitting on it, so i was wondering, is there somewhere i can get a fitting that can be welded to the griffen radiator, i assuum it would have to be aluminum.

 

If you can't find a fitting anywhere, you could probably get a small chunk of aluminum pipe and weld or braze it in place.

 

You could do that. Course if you want better cooling I can't really see a reason not to just get a stewart water pump or another aftermarket one and have a fitting on it. That way you don't have to mess with your brand new aluminum core radiator.

Welding on aluminum is tricky by the way. I would recommend using a solder on it. I've heard of other members soldering them on before.

I also believe that the griffons are part epoxy, so try not to get it really hot.

 

I guess that will be my next springtime upgrade then. Pick up one of those water pumps

 

actually the Griffins radiators are 100% alumin becuz they are Tig welded together and the temps from tig welding around from 5500* up to about 10000*. so welding a fitting on it wont be a problem.

 

Hmm that's a new one on me. Where did you get that info? I called up Griffin when I was thinking about getting a radiator and they told me for the most part it's weld'd but they still use epoxy some (If I recall right for the tank attachments, I might be wrong. Been at least a year+). I called up the 1-800 number or what ever for griffin and talked to a tech dept guy.

 

i looked at my radiator, if there is an epoxy then i most have not seen it but from what i saw on my griffen radiator it was all welded. and if there is an epoxy on it then still wlding on the raditor after reciveing it wont be to hard either.

 

Well that sound ok then. As long as they find an experienced welder who know how to weld on aluminum, wouldn't try to weld on my brand new 180+ radiator. (Had to add that I can just see some person trying to stick weld on aluminum).

 

well i went to skool for 3 yrs for welding and know a large amount of it. i can weld basiclly anything excupt for exotic metals like titanium and magnisuim and whatnot.
