Hey guys,

I bought a MK1 Focus 1.6 (2002) Petrol Friday. I've noticed soon as I start the car up the fan is on instantly, is this normal? My last car was a Punto and that only kicked in once it got warm.

Also, are these cars worth remapping for better mpg?

Hi welcome :)

Well, that wasn't much help at all, eh.

is the a/c on? that will kick the fan on at all times

It's not, no. It's gasless so I don't have it on :P

Look at the heater control dials, if they are set directional to where you see the orange windscreen icon then i think the fan will run on all the time ! hope that makes sense !

I assume you mean the radiator fan?

It should only normally kick in when the engine is up to temperature, where does the dash gauge sit at?

As the car is a naturally aspirated (non turbo) petrol getting it retuned will return very low gains (less than 5% improvement).

A good exhaust system and a low resistance air filter would produce slightly better gains.

Has the fan been frigged by the previous owner to stay on constantly I.e shorted with a piece of wire on the fan switch it's self if so I'd say it's got under lying probs .
