I have two more comments to my previous two comments.

1. It's possible to remove the water pump by only removing only the air manifold and front crossover pipe. I just did it in less than an hour. It's very tight, but it's possible.

2. If the car is still running, ask yourself WHY the water pump may have failed and test your thermostat. If you have excessive pressure in the top radiator hose or coolant reservoir and you're not seeing signs of a head gasket failure (white smoke in exhaust, exhaust smell in reservoir, bubbles/foam in reservoir) then check your thermostat. The easy test is to check when the car is hot and the top and bottom of the thermostat should be the same temperature (you can use a digital laser thermometer).

I replaced my water pump without replacing my thermostat and then coolant started leaking from somewhere else.
