Griffin Radiator Install

PostPost by: Evante » Fri Nov 13, 2020 10:19 pm

Hi All,

I am planning on installing a Griffin 26r type radiator over the winter in my 1972 Federal Sprint. I have seen pics of others who have done the same but no pics of the brackets used.

If anyone has pics of the brackets they fabricated, could you please post them? It would be greatly appreciated.

Thanks!

I don't have pics of the panels out of the car, but here they are in the car - also a '72 Federal Sprint.

Driver's side. I've hung a windshield washer bottle off of it.

Passenger side, with intake ducting removed. The fan relay is attached at the top.

I made up patterns out of cardboard to try to block off as much of the area between the radiator and inner fender as I could, then cut them out of aluminum sheet. Braced with some homemade steel sheet metal brackets. So far, so good, after 4-5k miles or so.

They aren't self tappers, they're machine screws that go into the threaded bosses that Griffin welds onto the radiator.

I have the TTR Radiator "Extra Large Triple Cross Flow For Cars In Extreme Power & Temperature".

I had expected to fashion brackets for it but TTR pointed out that the top and bottom hose connections alone provide a very solid and stable fixing. Moreover, this radiator is so wide there is really not much need for baffles on the sides. It takes up most of the available space.

So, installation (and removal as needed) is simply effected through the two hose connections. The radiator does not move at all and is quite secure. It sits in the same original location as the small, original radiator.

This radiator does an amazing job. Even with hot California temperatures and a high output motor, no cooling issues whatsoever. Big change from the undersized stock S4 radiator - always overheating even with a stock motor. Even overheated when I picked the car up at the factory in the UK and in the cooler UK climate. At the 500 mile checkup in the UK they changed out the dual gauge surmising that the temperature gauge was perhaps faulty. But, a new gauge provided no change in the indicated temperatures.

Holy crap, that's a huge radiator.

Mine is similar to Steve's. Cut and bent side brackets with bolts into the bosses on both sides. I have had it that way for 15 years now with no issues. I would recommend two 8" fans if you spend any time in traffic on hot days. I had one larger fan, but switched to the two smaller and now no issues even when sitting in traffic. I have the fans mounted to the front. I had them mounted to the back at one point, but found it made the interior of the car unbearably hot unless you were moving, and even then it was hotter than I wanted. Good luck, Dan

Graeme,

It appears your bonnet has some pins at the front that index into the body? And the stock 'rocker' style hinge is gone? Am I getting that right?
