I have a problem with the auxiliary engine heater on my 03 Mondeo TDCI. And I was wondering if it’s worth fixing?
The 60 Amp Fuse that feeds it was blown when I got the car. I replaced it but when I looked again it had blown again.
This is supposed to feed 3 X 250W heater plugs in the hose to the Heater matrix through 2 relays when below zero degrees C. Even if the relays took nothing, at 12 volts that’s 62.5 amps; at 13 volts that’s 58amps. It looks tightly-sized to say the least?
(1)The warranty is about to expire and the local Ford agent will “Trace the fault” but I will have to pay if no fault is found or a wiring snag is found.
Not all models have this heater, is it important? is it worth the gamble?
(2)Does anyone have experience of these heaters or have they had similar problems?

Many Thanks

Eljay

You should try to fix it because it helps the coolant heat faster, the engine goes to normal temp faster , you will have heat faster, and the engine "will feel better" when it's hot.
Here in Romania in winter we have (where I live) even -25 so.....this stuff helps !
Take care !
