Mitsubishi Magna Problems

It would appear the fluid has been overheated, so I would be doing a full flush of the transmission, not just a fluid change. I wouldn't bother about the coolant.

Magna belts are generally pretty durable, but the recommended change time is 100,000 km.

The most common cause of oil excessive consumption in Magnas is worn valve stem oil seals.

Check and if necessary reset the base idle speed. If the stepper motor has been faulty it could be that someone has attempted to get around the problem by adjusting the base idle, and now with the new stepper motor working as it should the idle is all over the place. You could also check the temperature sensor on the fuel-injection system to make sure it’s working correctly and sending out the correct signal.

Obviously you need to find out where the water is getting in. The most likely place is around the windscreen, but it could also be through damaged or misplaced seals on the firewall. Have someone run a hose over the windscreen while you get down in the footwell and watch for where the leak comes.

The battery probably needs replacing. It sounds like it’s down on power and the cold mornings have found it out.

The fan is designed to come on when the engine reaches a certain temperature and cycle as required to maintain a safe operating temperature. Yours seems to be doing that, and as there is no suggestion that the engine is overheating I wouldn’t be concerned about it. If you are get a mechanic to check the temperature switch controlling the fan’s operation.

It’s clearly not the tyres, so start looking at the front-end. Begin with the wheel bearings, and then check the drive shafts and any other rotating component.
