View Full Version : 2000 Cadillac Catera Auxillary Electric Water Pumps
01-21-13, 05:44 PM
I have to replace both of my auxillary water pumps in my 2000 Cadillac Catera 4-Door. My main water pump is O.K. One electric auxiliary pump is located behind the radiator, and the other is by the heater core. These look like identical parts but I want an expert to confirm that they are the same. The GM Dealer quoted $274 (P/N-GM 9120117) each for these but I looked online at the A1 Cardone website and their part number- Cardone 55-17911 is available through www.theautopartsshop.com for $34.54 each plus shipping. Funny, when I called two different cadillac dealers, they tell me that my car has only one aux pump?? Weird!! If these two aux pumps are the same, I will order two of them through the Auto Parts Shop online. They also give you a two year warranty. I wonder why the huge discrepancy in price even though one part is OEM and the other is after-market? Any help would be greatly appreciated. Thank you very much!!!!

Thank you so much JohnJJO!!!!!! I appreciate your help on this one!!!! The Cadillac parts guys at the dealerships obviously are mechanics!!! Can't believe they couldn't tell me that I had 2 aux water pumps. I will order the 2 pumps at www.theautopartsshop.com for $34.54 each. At that price, you can't beat it.
I made be wrong on this, but am sure the auxiliary water pump on the passenger side under the fill tank is the heater pump and comes on when you turn the heat on and the auxillary water pump on the drivers side next to the battery is the over heat pump and comes on when your car starts to get too hot.:suspense:
I tried to order a pump from www.theautopartsshop.com, but they are out of stock, thats after I order and they charge my card and then they say they don't have any and refunded my card. I went to Parts Geek.com and got the same part at the same price and was ship the same day.

I just had the same experience with the autopartsshop.com and autopartsexpress.com. On the last website autopartsexpress.com, I had to E-mail them a query to my order from last Wed 1/23 and they told me they cancelled my order. I just used partsgeek.com as you suggested gvjv3 and they had 2 that I needed and I just ordered those. Did yours show shipped after you ordered them? Thank you so much for this suggestion!!!
I got a email from them when they charge my card, next day got e-mail stating shipped and got tracking number, due 2-4-13

I just had parts geek refund my money since they are out of stock as well. I don't know why I'm having so many problems trying to order this part. I've ordered from 3 different parts sites and all of them have refunded my money stating they are out of stock.I guess I'll keep on trying. Thanks for your help though.

For some reason I couldn't find this link as I needed to replace the one under the overflow reservoir
Price is now ~ $ 52 + Shipping
Ended up buying used OEM on eBay, vs. aftermarket - But I have bookmarked the reference site - since there are two and who knows how long my used part will work.
Was loosing the reservoir amount every 500 miles, once the pace accelerated to every 90 - 120 miles the leak was easy to spot
reviving this thread real quick like. was curious if there was any special procedure to replacing the electric heater pump located under the reservoir, or is it just swap in and swap out? wasn't sure if i should be afraid of losing any fluid or getting any air in the system. thanks for any advice, in advance. a quick rundown of what happened to my 137K 01 catera sport.. the heat was working right along very well, then all of a sudden....after i was messing around under the hood because i noticed a couple of vacuum lines unhooked. repaired and reconnected those. one of them seemed to help the tranny kickdown some, which was nice. not that it was real bad before that. then i saw that the previous owner had unplugged and placed a jumper between the leads on the connector that goes to the low coolant level. I hooked it back up, but that still raises red flags and i instantly thought head gasket and cursed myself for buying this car that i have fallen in love with. after what i thought had been repairs, my heat would not get hot until RPM's were above 3000. the water temp gauge read and still reads perfectly in the middle in an acceptable amount of time. while back under the hood, i noticed some fluid below the auxiliary heater pump and then located fluid leaking from what seemed like the electrical connector end of the pump. I was losing coolant, but not at an alarming rate. and when i changed my oil i had not seen any indications of coolant in the oil and nor is there any oil in the reservoir.. so i think im in the clear with it being a head gasket issue. I am currently awaiting my new pump's arrival. also, while under the hood i had found a larger hose about 3/8 O.D., that as far as i could trace it with my feelers seems to come from the top of the tranny, that was unhooked on the top end. i cant see where it it would connect and it doesn't look like it has ever been on any sort of fitting as there is no stretching or anything like that. was curious if this was some sort of vent for the tranny or if it came from somewhere else? my sincerest apologies for the long post. and most likely this whole post should have been split up into separate forums. please, any advice or info or tips would be very much appreciated! thank you thank you!
