Fluidyne Radiator

Anyone install one of these yet. I'm not sure if it will "bolt-in" our cars. I see it listed for all E36 6 cyl cars. not sure if thats us also.

Hose ID?

The fluidyne radiator is advertised for the E36 6 cyl cars.. The manufacturer thinks the size is an almost sure thing for the M Coupe. But the Hose size is a question. Fluidyne thinks our inlet and outlet are 1 5/8", The radiator has 1 1/2" fittings.

Looking at the parts list I see the drivers side hose is the same p/n as the M3. But the passenger side is different.

The coupling flange (the part that holds thermostat/ is plastic and many of us replace this part with the alumnium one) is the same p/n for both M3 and M coupe ( 11-53-1-722-531) , so I would think the hose sizes must be the same on both cars.

This radiator would be a nice replacement for ours when they die and also would surely lower the temp some.

What is the inside diameter of our radiator hoses?
1 1/2" or 1 5/8"

Four options for radiators

[QUOTE=bob lindquist]The fluidyne radiator is advertised for the E36 6 cyl cars.. The manufacturer thinks the size is an almost sure thing for the M Coupe.[QUOTE]

It looks like there are serveral options for E36 M3 and M Coupe and Roadsters with S50/S52/S54.

Fluidyne all aluminum
PWR all aluminum
Zionsville Autosport all aluminum
BMW S54 17-11-2-227-281

On my next E36 M3 I will probably retrofit the S54 radiator and oil cooler to it.

Write up coming

Ok its a done deal Fluidyne radiator is due here today. I will do a photo and write up thing as the project progreses.

I would like to accurately measure the water temp in the stock radiator before the swap. How would the easiest and most accurate way be to measure the temp?

I could buy a s/w water gauge and screw it in temporarly somewhere. any suggestions?

A couple of thoughts here...

Is there a drain plug on the bottom of the radiator(s)? A temperature sensor could be installed there temporarily or pemanantly.

An infrared temp gun is useful to see the temperature change as the coolant flows through the core (I've used them to identify blockages in stationary engine cooling systems). It would be hard to do comparison tests on different radiators though under varying conditions.

The Fluidyne has all the same connections as the stock one. I just received it! Very nice work. There appear to be all the same threaded connections as the factory unit.


I understand the water temp gauge in our cars is some kind of computer analyzed generalization, rather that a linear reading. This is why I thought of using a gauge with actual degreed readings would be good to get some sort of baseline.


Anyone have a gauge to loan?

This is something I had in my mind, getting a high flow radiator in place of my stock one.

I wonder if Fluidyne model flows better than stock S54's radiator? Better yet, I wonder if radiator for my 2001 S54 M Roadster is the same as S54 M Roadster/Coupes?

Anyone?

Thanks.

Hose fit

I checked the samco silicone hose fit on the fluidyne. Very nice. Much better that the stock hoses.
