💦 Gates 42131 Premium Engine Water Pump: Ensure Optimal Cooling Performance Review

The Gates water pump has a MUCH better impeller than 99% of aftermarket water pumps. Put a cheap one on my engine 11,000 ago and it blew up. Gates on my other two Miats and now on my third. There is no reason to choose another WP.

Installed about a week ago and driven several hundred kilometers per trip. No leaks and works like a charm. The only difference is that the rounded triangular connector on the one I received was round instead, making it difficult to fit the part around it. This might lead some newbies to believe it won't work. I will not lower the price for it.

. Works great, looks solid. In the process I cut off one of the water pump bolts, so be careful! Hmm, the water pump center pulley was round while the OEM was like a wavy rotating part. I don't know how to describe it. Rather annoying, I remember he blocked another screw when putting everything back together. Complete with gaskets. I still used the seal from the manufacturer RTV.

The pump was for Mazda Miata. The second time I changed the timing belt, I changed the pump. Comparing the impeller of this pump to the last pump I bought was day and night. The impeller is a one piece casting with complex curves on the blades that simply say "flow". The last consisted of pieces of stainless steel welded together. I'm sure the attention to detail is better on parts that aren't visible (stock). Spend a few more dollars.

I know it was my stupid mistake. Somehow I ordered this for my '94 and didn't realize it was the wrong part until I assembled it (so the pump was already on). The two pumps are identical except that the 1.8L water pump has a tab on the left hand side that the alternator clamp bracket bolts to, while the 1.6L pump does not have this tab. So if you have 1.8, unless you don't plan on removing your generator for some reason, buy Gates 42134 instead. Other than that, it looks like a quality product.
