so its was time to change my water pump. got down to work. took everything else out of the way. removed the retaining (3 short and 1 long) bolts. my problem: water pump is just stuck in there.

did the M6 screw trick to jack it out but didn't work. may have smoothen the jack holes in the process (see shavings in attached pic). bathed it with wd40, still won't budge.

any ideas how to loosen the water pump and take it out???

any help is appreciated.

I've done this a few times... sometimes these guys are a bitch to get out... first thing I'd do... is spray a small amount of penetrating fluid in there... they have that at your local car parts store... then beat the shit out of it with either a rubber hammer... or a real hammer... and keep pulling... taking a screw driver and prying the face of it away... works well too...

Good Luck,

Les

I had this problem myself about 6 months ago, tried everything WD40, hammer, brute strength (ok jus strength in my case ).
In the end my mechanic mate came round and told me to put the pulley back on and gently wiggle it from side to side and up and down, did this and it fell out in under 30secs.
Hope this helps.

crow bar it is! not easily nonetheless. cant do it with my hands had to do it with a sidekick, literally. and it popped out.

next problem. the pump was one with the old hard plastic impeller. now it is a bit fragmented. some pieces about a size of a nickel may have been left inside the block. can't take them out. question is, what is the worst that can happen having to leave it in and put in a new pump with metal impeller? also, the likelihood that it is in fact going to happen?

your thoughts anyone?

Iím a ex-BMW tech and this fault isnít uncommon you need the biggest pair of grips (water pump pliers) that MAC sell you grab it with these and then pull, yank and twist it as had as you can until the little bas***d comes out.

The parts that were left over from your plastic impellar will do one of the following...

Disolve.... very unlikely... but the water coolant mixture isnt the most nuetral mixture in the world...

Get stuck in a line... or passage in the block... This is noted in many peoples engine overheating problems... solution... well there really isnt any great solutions... besides to pull flush your system... as best you can... take the hoses off and flush them by hand by means of a water hose or something of that nature... other than that... there is no great way to get those pieces of plastic out of there.... unless I havnt heard it yet...

Good Luck,

Les

well, i finally got it all done when the UPS knocked on my door with my new water pump. $62.xx from autopartsworld.com. that's the one with a metal impeller.

one more thing to do though, my check engine light went off just as my drive belt jumped off my then misaligned water pump pulley...

do i have to bring this to the stealership for them to reset the check engine light? a friend hinted to me about disconnecting the batteries for a few seconds. what's your take on this?

Disconnect the negative battery terminal for about a minute, to make sure it clears (usually takes a second) and it will go off unless the fault is still present.

Pegasus is an unknown quantity at this point
When I changed my water pump I really had to use brute force to remove it. There was some kind of vacuum that held the pump inside the engine. I even used the M6 method and just managed to break one of the sides of the pump. When I finally took it out, it pop out like a missile and hit the radiator. Fortunately, it did not damage it but I suggest that you be careful if you don't want to buy a new radiator in the process.
My 2 cents.

I used the M6 (i think it was a 6) method. The trick is to carefully, tighten each side sequentially.

To be honest - i don't think hammering and crow-bar-ing against your aluminum block is the best thing. Also, if you will the pump out unevenly, it seems like you could damage the area that makes the seal.

As for getting the new pump in, I bought the same M6 screws, but bought various lengths so I could sequentially pull the pump in from side to side.

Hope that helps...
