Hi,
I have a 1996 3.1 turbo diesel bighorn. I believe this means the engine is a 4JG2.
The timing belt needs replacing so I've had a few quotes to change it from different garages. A few places said to replace the water pump at the same time as its driven off the timing belt. Another place said that the water pump is driven off its own separate belt and so doesn't necessarily need replacement.
I'd like to know which place is right so I've been looking for a diagram of the water pump drive belt arrangement but cant find anything. Please could someone tell me if its driven from the timing belt or its own belt?
Thanks very much.
