    I replaced my failing AC Delco unit with this new GMB pump on my trailblazer when the fan clutch gave up the ghost. Its' fit, form, and function is the same as the much more expensive dealer part and OE installed part. They look identical next to each other. The hardest part of the install was removing the fan clutch after that it was cake. I've used these GMB pumps in many cars from Toyota, Ford, and GM vehicles and all are performing just as well as the day they were installed. I usually do wp replacement as routine maintenance at around 100K or so just to save headache from a catastrophic failure on the highway. The Trailblazer 4.2 I6 pump is a common issue due to faulty cooling fan clutch causing a wobble in the fan that eventually causes the pump to fail. This pump is up to the job and has proven itself over many applications that I've installed it in. I don't even look at the re-manufactured pumps if there is a new alternative listed. The new part is usually just a fraction more and is worth the little extra $$.

    This Water Pump Is Inexpensive To Replace. Meaning The Impeller Is Made Of Steel Rather Than Stainless Steel. Hopefully The Remainder Of The Components Are Of Equal Or Better Quality. Lets Hope It Lasts. I Received 160K of Faithful Service From The Factory Pump!! Stay Tuned.

    Comments about ToughOne Water Pump - New:

    Bought this pump to replace unit on 05 Isuzu Ascender LS 4.2L with 150k+ miles. After replacing fan clutch, I noticed the fan had started to wobble and coolant leaked from behind the water pump cover. Also heard a strange squeak during idle. Learned from online forums that meant the water pump was bad and a hazard if not changed immediately. I chose Advanced b/c I had a discount coupon from a previous purchase and didn't see any bad reviews. Installation is a pain- not b/c of the part, but b/c you have to remove the fan clutch to get access to the pump. Not impossible for the novice though. Many vid's and how-to's online. Remember to get new coolant, though. You will lose some doing this. Once old pump removed, new one went on with no prob's.

      Easy to install once you get the clutch fan off. Needed to use a chain from the pulley to the engine bracket to hold it from spinning. Running great now.
