Hi, I have a 1985 Corolla FX-GT 1600 (done 200,000kms) which has coolant leaking from behind one of the flywheels (or cog, or pully) below the cam belt cover. I can see the water leaking from behind the fly wheel when I look through the wheel arch. The water is a muddy brown color. I hope it is as simple as replacing a seal. Thank you. Mark

AS I remember, the water pump is cam belt driven. It sounds like a bad water pump. Also you will need a new timing belt and a tensioner if that is the case. Good Luck

Suggested Repair

Replace the water pump. Because it is driven by the timing belt, also replace the timing belt and tensioner.

Conversation Summary

The owner of a 1985 Toyota Corolla FX-GT reports muddy brown coolant leaking from behind a pulley below the cam-belt cover, visible through the wheel arch, and hopes a seal is the cause. The expert says the water pump is timing-belt driven and the leak sounds like a failed water pump, so the pump, timing belt, and tensioner should be replaced.
