Had my brother help me last time it went out, thinking of tackling it myself this time. How hard to replace? This is on a 97hammer w/454 mag.

piece of cake. I think it has like 3 bolts to remove the front cover and then with a little soap and water, slide the new one and tighten the housing back on. Do a search for the torque.

cool thanks, I'll give it a shot then. Couldn't find the torque setting?

Can not find it either now. Just do not overtighten it. About 15-20 ft/lb's should do it and make sure to tighten it like you would a wheel on a car, in a criss-cross pattern.

If paddle pieces are missing on the old one check for them on the water intake side of your oil cooler.
