I'm about to do a DIY remapwith the file from hdi tuning but I need to find the radiator fan fuse to remove it.
Anyone knowwhere it is?

It's supposed to be MF1 in the front of the engine fuse panel/mux unit but I'll be jiggered if I know how you're supposed to get to it

i saw someone else had put this up.wonder if this is it?

Check the engine bay fuse box too, I had a big fuse (as marked white, serving the radiator fan) which was getting hot and pulling too much current and flagging the engine light. Sounds weird but true.



To be fair you won't really know the cause without a code read

Oh, it's pre mux - I searched your posts and you said it was a 2002, perhaps this is different car

If your fuse panel looks like then then that's more than likely the right fuse.

Cheers steve. This is an x reg 2000. Gonna try that 1. I've heard people say when they remapped to ecu the fan came on but just ignored it. Don't really wanna do thAt. Rather do it properly

Why do you want to remove it?

I have carried out this operation many times - just let the fan run for the 80/90 seconds required for the download, never caused me a problem.

because thats what the instructions say to do.ive read posts where they've ignored it but dot really wanna do that.id rather do it to the letter. mind you if i cant get a definite fuse location i'll just leave it in

While I can't guarantee this, I imagine the instruction is there simply to stop involuntary bowel movements when the fan starts unexpectedly.

(Which, I guess, avoids anything unpleasant hitting it).

I asked the guy at hdi tuning and he said it's best to remove fuse co's if fan comes onwhen writing to ecu it could cause a power-drop and there is a possibility of that damaging the ecu. I've read a post where some1's fan came on when he was writing to the ecu & I don't think his was damaged. Though I suppose if I do the ecu writing whenengines completely cold the fan won't come on

Got my remapped file back and can't wait to do it tomorrow.(pc don't let me down.I'll be turning off Internet etc just in case any progs try to interfere wi the galletto prog). The guy said in no way can the prog be stopped or mucked about with once it's started. I'm tense just thinking bout doin it

So, did you remove the fuse, or decide to live dangerously?
