I just came to these forums to find some new tips about stuck Water Pumps for Aurora's with 4.0L Engines (seeing how the last post about this was dated for 2004 by DIGBY67 own troubles with it) as I (mostly my brother) will try to replace the water pump ourselves.

--SKIP AHEAD IF YOU DON'T WANT TO READ BACKGROUND STORY--
Before we found out the Water Pump was stuck, I took my car to the GM Service (August 4th) because of engine coolant leak that occured one day. Well since the car was under extended warranty (ends August 14th my Warranty so I thought I was lucky) they said the water pump was leaking and gasket so they were going to replace that and charge me $149 under warranty.

I thought this good deal so I said yes.

It wasn't until monday they told me it will cost $1,300 all of a sudden because they said the water pump is stuck to the water housing and that the only way to remove it is to lower the engine and remove replacing the housing itself. (Their explaination to how this might occured is that MAYBE one of the tablets they use for the car may have leaked out and some how "froze" the two components together.) Anyways, during the process of removing the stuck thing, they said they "broke" a 400lb pulley just to try and get it off.

I did not want to pay $1,300 for this service mainly because I am just a college student so paying that much is more then a semester cost for me and books.
--END SKIPPING OF BACKGROUND STORY--

Anyways, the car is still at the GM Service and I will have the car towed from them to my house as my brother said he will try to remove it without having to remove the engine. He also said before he starts the work, that I look around the internet for tips and advice.

So far these are the information I got from past posts before going ahead with this project:

1 Mechanic (My brother is a Mechanic for Nissan but he never really done work to a V8 before.)

Sealant Tabs - Read that this is important and can obtain from GM Services. I will ask for some of these tablets before heading off home with the car.

Special Water Pump Removing Tool - Heard this was important as my car falls under the 97-99 category for removing the water pump. But my brother may want to try other methods instead. However I will ask the GM Service people if we can borrow this tool seeing how they made the car literally unoperable now.

Heating Gun - My brother actually said the GM Service guys probably knew they could use this method however wanted the extra money because they broke their 400lb pulley. And yes, the GM people did NOT try the heating method.

Dex-Cool - Recommended by users from on the internet. Along with Distilled Water.

Hammer - Along with some holding device for the water pump as this may work too perhaps from what I read?

Thats everything I have gathered so far while researching. So far I was hoping for more recent posts and information but none available. If anyone else has new tips or suggestions, please don't hesitate to respond!

Thank you in advance!
