Discovered a small coolant leak
While crawling under my front end yesterday, I noticed coolant dribbling down the front of the engine and landing on top of the lower radiator hose. I suspect a water pump seal is beginning to leak. It isn't dripping on the ground yet, but it seemed I was topping off the coolant every week. I was planning to bring the truck to the stealership for a coolant and brake system flush, but now I am wondering if I should just do the coolant flush and water pump r/r myself. How difficult is a water pump r/r?

I had the same problem with my 2000 7.3., leaking on top of the hose.
The water pumps have rubber o-ring like gaskets that fit in a slot in the water pump. When I took my pump off the gasket was hard as rock.
You can buy just the gaskets, but I would replace the entire pump and thermostat, if you have high mileage. The hardest part to doing it, is taking off the fan. But with the right tools you can do the job in less than 2 hours.

The website for ordering a 203 degree thermo and the billet housing is www.dieselsitetoo.com. There is a good article that explains the reason for using it. Bob Riley is a good guy to deal with and will answer any questions you have. Several of the mods I have done to my Ex have come from him and they all work as advertised. Sorry I couldn't get back to you sooner, Jumbo_Ute, I tried PM'ing you, but I got e message saying I hadn't been a member long enough or posted enough. Anyway, hope you found the info you were looking for.
