timing chain cover is leaking coolant. what is fair price for repair?

I agree with pushrod these engines are known for water pumps going instead of timing cover could still be intake or cover but like pushrod said have the cooling system pressure tested

If 3.1 engine,, look closely underside of hood on passenger side for a line drawn by coolant splatter, IF you see that, the water pump is leaking!.....Have another mechanic pressure test the system and check for leaks,, timing cover gasket leak is the least likely suspect....but possible!

approx 700.00 if that is your problem
