Rear of engine (which is toward the front of the coach)?

Or front of engine (toward rear of coach)?

And, is it on the centerline (left to right) or off center?

Sounds like water pump on a Cummins. Easy to change once you have access to it. Get two five gallon buckets and drain coolant. Remove rock shield guards and grates from underneath. Remove belt with breaker bar on tensioner. Remove three bolts holding water pump to block. Remove water pump with o-ring seal.

Reverse procedure to install, now will be a good time to put in fresh antifreeze and replace belt.
