How can i determine which one i have without taking off the fan? Not having a lot of free time, i was just going to save some $$ by buying the pump and just taking it in to have it replaced, but if i have to tear everything apart just to find out, i might as well just do it. Can anyone tell me an easy way to find out which kind of pump i have?
Ok well the first thing you want to do is make sure it's not the bypass hose that is leaking, if the bypass hose is leaking it is very easy to mis-diagnose a bad water pump as this has happened to me but I was smart enough to stick my finger under the accessory bracket and feel the underside of the bypass hose and to my luck their was a cut in it. Small 10 dollar hose or make it your self 50 cents. Anyways you are going to have the remove the fan and drive anyways, just a tip of advice to save you the headache lol don't try to remove the fan with the serp belt on because the pulley will spin in the belt, the easy thing to do is to buy a water pump pulley tool, it looks like a giant "U" and the end and on each end is 2 metal pins that stick out, these pins pop into the pulley allowing you to hold the pulley in place while you go in with a adj crescent wrench and remove the bolt. Elsewise it's quite hard to move the fan drive from the pulley.
