Hey all.

Just a very quick question, I have found a steel fan from a series 2 xj6 with no fan clutch.

I have read about disintegrating plastic fans on the S3 so want to replace mine with a steel one.

Will this just bolt on to my fan clutch?

 

Its been a while, and I reckon Doug will know more than me, but, The fan clucth for the steel fan is different to the plastic one, and I dont remember the differences.

The radiator on the S3 is designed for the airflow available with that plastic fan, which is more than the steel fan. The S2 radiator is larger from memory.

Much like the PreHE and HE V12 radiators, The former is a "monster" with steel fan, the latter is smaller with a plastic fan, or twin thermo fans now in most owners cases.

 

Grant is correct. The steel fan uses a different clutch.

The clutch for the steel fans is the earlier type with the single center bolt. This is a non-thermal fan clutch. It allows the fan to stay engaged until xxx-RPM is reached....at which point I allows slippage.

The plastic fans used a thermal clutch with a more common 4-bolt mounting. This type of clutch (recognizable by the little temp sensing coil spring on the front face) allows slippage until xxx-temperature is reached at which point it engages.

By the way, the metal fan is not immune from failure!

And one whose age is unknown. Might be just fine, but
on the verge of failure as well. Flying plastic can do a lot of
damage. I think flying steel would do even more...


And, as it is sans clutch, finding one might be an issue. More money at least.


Why not seek the improved version, the black plastic.


Or time for Efans. A good used one or a brace. New not all that pricey
if one searches. Thermocontrol is slick.


But, at the very least do a visual on the steel one. Perhaps even a
visit to a well equipped machine shop for Magnaflux.


I've had past adventures with errant flying fans. touchy about them.
