🌡️ Gates 34046 Engine Coolant Thermostat with Integrated Housing Review

Ordered this thermostat housing for my Mazda 3 2005 2.0l perfect fit! solved my problem with Check Engine Light (engine codes) po126 and po128

Used by my friends 2007 Mazda MX5. It was pretty easy to install. I would say 1.5 hours. As always, Gates products are of the highest quality. Replaced to fix the coolant code that many of these Mazdas get.

This was a direct replacement for the thermostat and housing in my 2006 Mazda 3i (2.0 liter engine). Fit and finish is very good and no issues after 1 month and >1000 miles of riding in the summer heat. Two thumbs up.

Encaja a la perfection mi Mazda 5 2006. No function. No hase su función de abrir para que circule el agua y calienta el motor por lo mismo. El carro está bien purgado, tiene solo coole at aun así calienta. Y se que no habré porque todos las mangueras están calientes, y la de la salida del termostato está fría.

Until now, auto parts I've bought from Revain have only worked, so I assumed this one would work too. Instead, my car's cooling behavior was consistent with a stuck half-open valve: the engine was initially too cold, resulting in a P0126, but later overheated. I got a real Mazda replacement on eBay for only $15(!) and it works.

Don't waste your time or money on this thermostat. I replaced the thermostat on a 2006 Mazda in December 2019 with the help of Gates. The first lasted less than 2 weeks before opening and triggering the check engine light. Got a replacement part and fast forward 15 months and here we are again. Save yourself the hassle and buy an OEM part.

The two piece design makes installation a little tricky. The block didn't regulate the coolant flow properly and I was stuck with a colder than usual engine until I installed the Motorad block. I highly recommend skipping this product and spending the extra $5 on the motorad which is a one piece design (like an OEM thermostat) and has worked well for the past month.

After receiving the thermostat housing and comparing it with the original housing, differences are to be expected. I have attached some photos comparing the original thermostat housing and the Gates thermostat housing. The original is the one that came from the dealer and was never altered before installation. The thermostat works and not a single leak has occurred in a week of use. I'll definitely check the thermostat housing in a few months. I'm sure it will hold up, but the design is…
