It might be next summer before my car is finished anyway, at the rate I'm going.

Hello

The S4 radiator is significantly different than the earlier models, and the sheet metal attachment points are completely different. It is tilted and the bottom end sits more toward the front of the car as well s having some cooling holes cut in the base. It could be made to fit but a lot of metal work would have to be done.

I have an old IAP aluminum radiator in mine that copies the basic shape and layout of the original radiator, and it does a good job, but I am not not putting out 170 BHP.

I was also looking at some of the Griffin radiators and adapting on of them in. I think it could be done, but there are going to have to be some mods

George, Would you mind sending me a PM with your phone number so that I can pick your brain about the installation.
Thanks.

I got this radiator for my 81 Spider. Great for cooling and with a front mounted fan it opened up the engine compartment.

It looks like you did a nice job of the installation. Which top radiator hose are you using?

Also nice to see Webers.

A hose from the local parts house, it works but not the right one. I had installed a temp sensor from a VW inline on the bottom host to run the fan but the temp range was wrong. I connected the fan to the ignition system so the fan comes on with the key. The fan and radiator as well as all my high performance parts came from Wes Ingram. With the cams, pistons, valves and 45 DCOE's we figure around 185 HP. I just got back from from the Ozarks where I put 700 miles on the engine and it ran perfectly.

I installed the new radiator today. My old SPAL fan fit perfectly. I struggled with a couple of potential top hoses before I bought a Dayco Flexible radiator hose, part number 81041. I cut it to length and removed a length of steel spiral wire so that it would seal properly at the cut end. I have not yet wired up the fan control or started on the oil cooler hook up. Thanks to Conedriver who answered some installation questions.

Oil cooler installation

The Wes Ingram radiator has a built in oil cooler. I decided to run without it but the fan runs a lot in traffic now that the weather has warmed up so I hooked up the cooler today. Pictures show the detail. Space is tight around the hose connections, the water pump and the alternator pulley. I bought a sandwich type adapter on ebay for about $30 and a pair of hoses with AN10 fittings for about $60.
I started the car and let it idle for 15 minutes while I checked for leaks and the temperature gauge settled at 180 and the fan did not cut in, so the oil cooler is doing it's job. The true test will be in July when the ambient temp is around 100 degrees.

Recoring stock radiator is a possibility - maybe get more tubes and higher efficiency. Giulietta radiator recore, plus a few minor repairs, cost me just under $500

I have a radiator that is essentially identical to the Wes Ingram radiator, but didn't come from him. With the oil cooler hooked up, temps stayed rock solid even driving on the track in 90+ temps and a turbo dumping extra heat in. With an electric fan, it also keeps temps very reasonable sitting in traffic in similar temps. They are a great solution.

Don't copy my routing of the hoses to the radiator! The stainless braid is abrasive and will make a hole in the aluminum fins if they come into contact. Loop the hoses towards the fender rather than behind the radiator.

@Alfajay

I honestly have never been a fan...(excuse the pun) of aluminum rads. Good multirow brass and separate oil cooler, unless your really weight conscious.

The older I get.. the faster I was....

FWIW, the best place for a fan temperature sensor is the upper radiator hose, or the input to the top of the radiator. This will turn on the fan whenever the thermostat opens and sends hot water into the radiator. Fan will go off when the thermostat closes.
