Overheating - Have you checked the fan fuse?

Dieter wrote

It's vital for all MGF built before YD511059 :omg:
We found this issue back in 2004. Been on a trip in the Alps with 30 cars and my MGF coolant boiled when I parked her at the first pass, stop at Penser Joch.
Thought it's the dreaded head gasket, but after some investigation with help of Tony ( http://www.apttony.co.uk/index_MGF.html ) we found the front fan sticky and the Fuse F2 had blown.
Made the fan rotation again by hand and replaced fuse with a 20Amp type after comparing my fuse panel cover with another friends TF parking beside mine.

and

scroll down to F2
:yesnod:
btw. as another precaution against a blown fuse F2 I put a buzzer parallel to the fuse :oops:
In case my fan gets stuck again and the even the 20Amp blows then the buzzer will make noise.

:yesnod: Uprate the fan fuses to 20 amp. Helps prevent them blowing if the fan is a bit stiff on start up. MGR did it in later TFs.

That's a good idea! :yesnod: Do you have a wiring diagram?

Thanks to deiter for the tip regarding the 20 amp fuse, job done, have a low level coolant alarm coming soon, have sorted the stuck on brake lights thanks to another dieter tip, and will upload some pictures of the beautiful devon landscape when it stops pouring down!! Still, has helped me identify a leaky door seal so another job to do!

Nope, just an easy description *How to*
To buy
- 12V buzzer with black and red wires
- crimp sleave M4? (check bolt size be4 you buy, could be M5
- Y- connector

disconnect Battery for save works
Clip off upper cover of the front fuse panel
Bolt off front fuse panel.
Clip off lower cover

Locate the hole in fuse panel (see red arrrow) and lead the black (-) buzzer wire through the hole (from top to bottom.)

Locate brown wire at Fuse # F2 from below (blue arrow) and connect the black buzzer wire with Y-Connector.
Enhance wire if it's to short.
close lower cover. Take care on the black wire.
Put buzzer into fuse panel
Bolt panel back in place
Remove the hex-screw at the plus connection.
Crimp sleave connector to red wire and bolt red wire with sleave to plus


Reconnect battery, synchronize alarm blipper with four times keying a button.
Test:
Put ignition on
Pull fuse F2.
---->Buzzer should come off :woohoo:
Put back Fuse F2
<---Buzzer silent. :woohoo:

If the Buzzer is sounding ongoing ... check wether F2 is broken

Thanks Dieter :thumbsup:

looks like a 'how to' to me

With your permission Dieter, I'll copy this into the How to A-Z. :yesnod:
Could you just say what you mean by a 'Y connector'? I'm not familiar with that term.
