cadillacjeff7777 Posted December 11, 2013 Report Share Posted December 11, 2013 Has anyone been down this road before? Is it fairly straight forward? The pulley on the camshaft will need replacement as it is severely damaged. I am aware to use a P/S pulley puller or risk damaging the camshaft. Anything else that I should be worried about? Do I need to get a gasket or just a tube of Permatex? Does it need a gasket and Permatex? 2008 DTS Link to comment Share on other sites More sharing options...
KHE Posted December 12, 2013 Report Share Posted December 12, 2013 The pump cover gasket is a bell shaped o-ring. Some say it's reusable but I'd get a new one. You will need the water pump removal installation tool. Sometimes the pump is corroded in place and you may need to use an impact wrench to loosen the pump. The pump is removed by turning CLOCKWISE. Just the opposite of what most are used to. I'd recommend the OEM pump too.

cadillacjeff7777 Posted December 12, 2013 Author Report Share Posted December 12, 2013 OEM pump as in go to the dealer and buy the pump? Thanks for the note on turning it clockwise. I would have been stuck on that. I do have air so I'll start the impact on 1 try to loosen it. I have figured that it just bolted on. 2008 DTS Link to comment Share on other sites More sharing options...
cadillacjeff7777 Posted December 12, 2013 Author Report Share Posted December 12, 2013 Is this not the water pump? What is supposed to be turned? http://www.1aauto.com/1A/WaterPumps/Cadillac/DTS/ACEWP00012/553576-2008?utm_campaign=gb_csv_br&utm_content=EWP&gclid=CPjr3MWcqLsCFahj7Aodm2gA3A 2008 DTS Link to comment Share on other sites More sharing options...

I do have air so I'll start the impact on 1 try to loosen it. I have figured that it just bolted on. OEM would be AC Delco OES line which is the same as the dealer would install. I buy AC Delco parts through a local distributor for less than aftermarket parts at the local parts store for most of the time. Is this not the water pump?

I gave you some wrong information. On the older Northstars, the pump was removed and installed with a special socket. That is not required in your case.

cadillacjeff7777 Posted December 12, 2013 Author Report Share Posted December 12, 2013 Oh my. More in depth than I was anticipating. Does anyone have a parts list with part numbers of what I need to get(presumably the items at the end of the second video)? 2008 DTS Link to comment Share on other sites More sharing options...
KHE Posted December 13, 2013 Report Share Posted December 13, 2013 Jeff, I think you are the first one on this forum to tackle the newer generation water pump R&R. This place has online diagrams that should help you: http://www.gmpartsgiant.com/ Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...
cadillacjeff7777 Posted December 13, 2013 Author Report Share Posted December 13, 2013 Ok, I'm ordering up the parts now and will pick them up. Should I replace the belt tensioner assembly or can I skip that? It's almost $60 that could go towards something else being that it's the Christmas season. 2008 DTS Link to comment Share on other sites More sharing options...

It's almost $60 that could go towards something else being that it's the Christmas season. Check the bearing - if the bearing is OK (not growling and not free-spinning), you can probably skip replacing the tensioner. The tensioner bearing can't be replaced separately since the pulley portion is overmolded onto it BUT, if it freely spins, you can take a small screw driver and gently pry out the seal and work some bearing grease into the bearing and replace the seal.

cadillacjeff7777 Posted December 14, 2013 Author Report Share Posted December 14, 2013 5 1/2 hours into this job and I have yet to get the water pump and housing off. I'd just assume send the car to the scrap yard than to ever do this again. 2008 DTS Link to comment Share on other sites More sharing options...
cadillacjeff7777 Posted December 14, 2013 Author Report Share Posted December 14, 2013 His videos are lacking something. I have removed all of the nuts and bolts that he specified and the housing does not come off. It is still held firmly to the block. No idea what is holding it either. 2008 DTS Link to comment Share on other sites More sharing options...
Logan Posted December 14, 2013 Report Share Posted December 14, 2013 Not sure why GM went back to a traditional water pump on the Northstar. The cartridge style water pump seemed to work fine for the application....turned a hour job into a day job...go figure. It may now be the hardest water pump on the market to service. Anyway, it appears the crossover pipe has to come off. I attached a pic from the service manual that may help. I would almost be tempted to replace the crossover with the older style.

The bottom two in the rear where the ones that he missed in his video. I don't see how they could be loosened without separating the motor from the tranny. Everything is thrown in the trunk now and the car will be towed to the dealership. 2008 DTS Link to comment Share on other sites More sharing options...

The tube that comes up presumably for crank case gases was broken in two places. I suspect that the dealership did this to generate more money but I have no way of proving it so whatever. I have been in discussions with Cadillac Customer Care and have brought this to their attention but asked that they not confront anyone over it until I get my car back from their possession. 2008 DTS Link to comment Share on other sites More sharing options...

I think you would have noticed it broken before you took it to the dealer, if in fact it WAS broken... After all, you had been under the hood for a number of hours...

Logan Posted December 19, 2013 Report Share Posted December 19, 2013 FYI...Looking at the GM service manual...2004 and 2005 model year engines still used the older style cartridge water pump. 2006 shows the new style water pump.
