  7. Water pump

    I am thinking of replacing the water pump on my 450, I recently noticed slight play on the bearing and think it is the source of a rattle I have had since I bought the car, I would rather replace it before it fails. Prices seem to vary wildly, are there any preferred brands or brands to avoid?

  12. Mystery access panel

    I was painting under the wheel arch liners on my 450 and have found a small access panel under the right hand arch held in by two bolts, it seems to allow access to the inside of the tridion, I am guessing it gives access for some wiring or some such, anyone know for sure?

  13. What turns the fan on?

    Hi all. Feel a bit silly asking us but just want to check. What turns the cooling fan on? Is it straight from the temp sensor on top of the engine (with the easily lost circlip)? Or does that send to the ECU that then decides when to turn the fan on? Seems to be holding on 4 blobs on...

  14. Vibration when clutch engages.

    I have recently bought a ForTwo and it has a severe vibration when the clutch engages especially when pulling away from standstill. The gear changes are fine. Is there anything that can be adjusted or is it a replacement clutch. Any ideas appreciated.

  16. CDi Exhausts

    It looks like I might be getting the 2001 CDI I sold a couple of years ago back but it in that time, it has got into a state with needing a new turbo and exhaust.

  17. Which rear shock absorbers 2002 Fortwo 599cc

    Hello all, Having had several MOT advisory's about wear to rear shock bushes I figure its time to change them. The thing is I can only find 2004 onwards listed by all motor factors. Does anyone know if 2002 shocks are the same as 2004? The variant is MCC01B05E3 If that helps.
