Water pump died

[John Harrison]

On the trip home the water pump on the 454 locked up. The mechanic where I work, a good guy and worth it I am sure, wants $600 labor to replace it. To be honest I don't have that much free cash. Can anyone give me some pointers on removing the front end on a 91 Holiday Rambler Aluma-lite and a list of tools so I can try and do this myself. I have replaced water pumps on 350's but not motorhomes.

i was thinking of tackling this prolly from the bottom. it may have a 2 piece shroud on it. careful loosening the hose on the radiator. remove clamp break seal gently with a screwdriver on the hose edge. photograph the belt placement. see if fan and clutch will come off in one piece. remove pump and scrape surfaces. use a thread sealant on the bolts into the water jacket.

High John, If you stripped the water pump down, removed the fan then the pulley would you need to pull parts off the nose. The pump, if memory serves just flush mounts to the block; there's no dowels or parts of the pump that would interfere or need to be pried out ? Also a simple socket wrench set and hand tools would be the tool list. another thing you may want to loosen Any belts that interfere.
