Problem - Not cooling down!

[S1LRD]

Not a great day for the cupra yesterday! Got a 6" crack across my windscreen which got bigger and bigger every mile i drove!
Then while parked up for bout 20mins with the engine running it started to overheat, which had never happened befor.
Then when i got home and stoped the engine and locked the car, i noticed it wasnt cooling down like it always has done.

There are no lights on the dash apart from the red one and a loud beep when it started over heating!
Any ideas of wats up guys???

Thanx

Just wondering whether your radiator fan is coming on? Do you know about the fuse issue with the Mk3?

the right hand fuse on top of your battery that controls the Radiator fan and AC has a habit of blowing, that is the first thing i'd check. Its a 30A one.

Is the radiator fan the one u can hear when u usualy switch the engine off?,
wasnt aware of the problem, is this fuse easy to find and check?

 

[Big_Lad]

Yes it is.

There is a plastic cover on top of your battery, squeeze the sides to together and lift it up, you should see three green fuses underneath, the one that you need to look at is the right hand one. Like i said this might be the problem. I've experienced this and so have a few other people.

You first notice it when your AC is not cold anymore (i have mine on all the time) so when thats the case i pop the bonnet and have a look, since i've had my car (July this year) its gone twice so i keep a small stash of fuses in my car.

i've just had a look, and i cant get the fuse out? it looks abit bent compared to the other two but doesnt look blown. do i need to get it out to see properly?

sounds like a fuse, Mine was over heating in the summer due to a fuse. It stopped the fan kicking in. Got it sorted in the end tho

 

[Big_Lad]

Its an absolute pain to try and get out, but you should be able to see if the metal element inside is blown.

With mine, the fuse had melted so much that the plastic had covered the contacts in the fuse holder, so i do need to get a replacement, althought for the time being i did manage to clean them

 

[S1LRD]

yes mate just got her out and like you say happened to you, the green plastic has melted onto the contacts, wats the best wat to clean it up? anyone know a price of a new fuse holder?

 

[Big_Lad]

Might as well just buy another one from a dealer. Not sure how much they cost though.

 

[Dan Cupra R]

I think i payed about £90ish as I had diagnostics done as well. Fuse box is about £40ish IIRC

 

[pickie]

yeh your looking 40-60 ish for a new one as i had a new one but cant remember the exact amount

 

[S1LRD]

just sorted one, just over 40quid. seems alot for wat it is, but i think mine is ruined!

Trust me, you'll be thankful, i've seen some photos where engine bays have caught fire because of this fuse. Not a pretty site!

 

[S1LRD]

i can imagine. so is my car drivable without this fuse?

 

[davidol]

no, it'll overheat very quickly

 

[Big_Lad]

Well you've been driving up until now haven't you? I was driving mine for about two weeks before i noticed. But i wouldn't recommend it

That is the auxilary water pump you can hear when you switch off not the radiator fan !!

Anyone know how easy this fuse holder is to fit??
