Changing the water pump on '91 Prelude

Who designs these things?

The advantage of the Honda over a Ford is the commitment to metric.  With 4 sockets it would be pretty straight forward to get through all of the engine.  On the Taurus especially every other bolt was metric or standard.  

Now I have changed a few water pumps on Gimpy the Wonder Taurus, but this Honda made the Taurus look easy.  The head cover had to come off, and the accessory belts.  And the timing belt. And the crankshaft pulley.  And the left engine mount.

Otherwise it was pretty easy to wiggle the pump up in between stuff and onto the block.

BUT we did it.  In one night. With no injuries past cut knuckles.  And actually, doing work with friends in good spirits is always a pleasure.

The trick is in lowering the engine by about an inch.  The pullies, dust covers and pump all fit past the fender much easier.  also a 1 1/2 inch extension might be nice. I picked one up at 7 corners after the fact because it was so dearly missed.  Tools you want to have also: 10mm socket, 10mm box end wrench, 12mm socket, 17mm deep socket, 19mm socket, razor blade, hydraulic jack, blocks, 12in extension, 1 1/2in extension, universal joint, a stout breaker bar, a torque wrench, oven, and a better or at least less cryptic shop manual than the Chilton's because damn.  The oven is to bake pizza, you'll get hungry.  I would strongly suggest buying belts to replace all the belts and radiator hoses, since almost everything needs to come apart anyway.

'd agree with you, except we'd have to come to an Accord first! ;-P

Ahh, so that's why the shop offered to replace the water pump on my '92 Civic when I had the timing belt replaced, even though it still worked. Seems wasteful, but chances are good that the pump is designed to last for about the same mileage as the belt.
