I think my fan works cause it ran for a bit today after I turned the engine off.
That's normal providing it was because the aircon system was running. Do the Demist Test to confirm it's operating correctly.
Where is the max marker on the coolant bottle?
At the base of the fins. If the coolant level drops, or you remove a bit, you'll see the MIN/MAX markers directly below the filler neck.
when I put the key on position 2 I hear 2 noises, first I assume is the fuel pump, then theres a second whirring noise, is that a fan?
No not the radiator fan for sure. Various systems run self tests/motors at ignition on/off like the headlamp motors, the heater system flow controllers. You're unlikely to hear the fuel pump in the tank. You will hear it if you listen at the tank filler neck and someone turn on the ignition.
Also what makes post 2001 models more suceptible to FFS?
They are fitted with a different filter design. It's a screw together module which tends to separate (FFS).
I have a 2003 so could I have it?
It will have the later filter module. If there isn't a FOC already in place, I'd suggest you fit one when you can. It may well improve the issues you mention, but it's a good insurance policy anyway. You don't want to get stuck out in the sticks with FFS on a rainy night! TC
