Temperamental Fans

[pepper]

A couple of months ago I noticed my 1993 5.0 litre Griff getting very warm in traffic. I subsequently realised that only one fan was working. I've since had it fixed by TVR, however on a very enjoyable run to work this morning, I noticed the temp going above 90 degrees and heading towards the red again - the reason being the other fan has now stopped.

Not being a mechanic, I tried to get it booked in to a local garage near work instead of sweating about breaking down on the way home. The garage is full, therefore can anyone recommend what I could do to try and fix it!?

Short the otter switch with some cable to make sure the fans come on, if they do not check the relay, it they do, then the otter is duff.

If ones working and the other isn't, could be the fuse?
I think some cars have two fuses, one for each fan, and some have one big 40A for both. Mines a precat with two fans, and from memory its got two fuses, could be wrong tho'.

I've had exactly the same with my 4.3 Griff. Investigation has revealed that the failing fan is just knackered. I think it's caused by water running down the bonnet and directly into the fan motor, where it sits until the fan is next used. Try turning the blades of the duff fan. My first one that went was jammed solid. I assume the previous owner had just not noticed!! My other one is on the blink now, but isn't entirely jammed, just very stiff.

They're fairly easy to replace. Four securing bolts on the top and bottom of the rad frame (two on each). The hardest part is working out how to get the fans in and out of the engine bay, because it's fairly tight in there!! I got my new fan from Christopher Neil - about 55 quid delivered.

Hope this is helpful.

Thanks Dan, Andy.

I'll have a go at turning the fan before leaving for home. I'll have to play with the switch tonigh...

Could be a long journey back if I'm stop / starting...!

While your checking stuff, un-plug the connector to the actual fan, clean it best you can, wagle-it-about-a-bit and give it blast of WD40.

I’ve had one fan stop and after raking about in the foot well for the fuses, which were both intact, it turned out just to be the joint at the plug/connector.

Cheers,

Simon.
