    • Good quality
Have had on vehicle for 3 months. Exactly like the original part. Would recommend.

    • Works as it should.
I have a 2008 Colorado with the 3.7L 5-cylinder engine. After putting over 165,000 miles on it, I started noticing the engine coolant would sometimes take a long time to reach normal operating temperature, and occasionally it would never actually get that high on cooler days. Then I started getting an intermittent "AC OFF" warning message on the display in the dash. After doing a little research, I found out that the computer in my truck is programmed to disable the air conditioner compressor in the event that the engine coolant temperature takes too long to reach a minimum acceptable level (I think it's 160°F or close to it). From what I can tell, this is to help minimize engine overheating in the event of a coolant loss. I mounted a ScanGaugeII on my dash so that I could use it to view information that my normal gauges don't show (alternator voltage, fuel mileage, etc). Since the temperature gauge in my dash doesn't have numbers printed on it, I used my ScanGaugeII to see exactly what the coolant temperature actually was. On warm days, it would run anywhere between 165°F and 185°F if I gave the engine a chance to warm up properly. It would still take much longer than it should, though. On cooler days, it would sometimes never even reach 160°F, and of course the A/C compressor would be disabled. It was pretty obvious to me that the cause must be that the thermostat had started opening too early. So I ordered this one to replace the original thermostat. The manufacturing quality seems to be on par with the factory thermostat, so no complaints there. The real complaints I have are with GM and their ridiculous designs. Instead of using a normal thermostat that costs 7 or 8 bucks and is available at any parts store, GM had to design a special thermostat that costs 3 or 4 times as much. And they couldn't design the engine so that the thermostat is easy to get to, either. No, they made it so I had to jack up the front end of my truck, pull off the driver's side front wheel, remove the wheel well liner, and use ratchet extensions with wobble adapters to get the thermostat out. Here's a tip for anyone else that needs to replace the thermostat in their Colorado/Canyon/H3/etc: use some dielectric grease to hold the O-ring in the groove. It will make installing the thermostat a bazillion times easier. Just make sure the groove on the thermostat, the O-ring itself, and the flat mating surface on the side of the engine block are as clean as possible before putting the grease on it. Anyway, once I got it installed, put the lower radiator hose back on, and filled up the system with fresh coolant, everything has been working perfectly. The engine gets up to normal operating temperature quickly, and it stays there regardless of how I drive, what the outside temperature is, or whether or not the A/C or heater is running. This one does run a bit hotter than the factory thermostat, but that was a retroactive design change on GM's part. The original thermostat would keep the engine coolant between 190°F and 210°F normally in my truck. This new thermostat keeps it between 204°F and 218°F (according to what my ScanGaugeII shows me). This is well within the engine's design tolerances, and from what other people have said online, this should actually help increase fuel mileage a little bit under normal conditions. I'll keep an eye on my MPG to see if this makes a difference for me. Even if it doesn't, I'm still happy that everything is working properly again. I've only had it installed for a few weeks now, but it's working the way it's supposed to so far. If that changes, I'll update this review. As it stands right now, I am happy with this purchase. ... show more

This thermostat is not what you want for a 2005 Canyon. It's runs at 210. Save your headache and go to ORileys and get the Murray 187. It keeps temp where it should be.

    • Fit H3 Hummer perfectly
As a mechanic, I have never had a problem with dorman replacement parts. They are less expensive than OEM but the quality is just as good if not better in some cases. The oring is a pain to get centered but that's more of a problem with the design of the engine bay, not the part itself.

    • This is the one you want for your 2004-2006 1/2 Colorado
Had to replace the original 180 thermostat in my 04 Colorado and if your reading this you know finding a true 180' is difficult at best. GM and others have a 195' available but this Dorman stat is a true 190' with the hot water candy thermometer test confirming this. With the old stat my temp gauge ran at about a 1/8 in winter and almost to a 1/4 on a hot sumer day. This one is reading a little over a 1/4 to 3/8 so I expect this summer it may reach to the halfway mark. This is a quality unit nicely cast and machined unlike a Motorad that I looked at which does not have the oem style air bleed passage and casting is fair at best I would not recommend the Motorad. I have a total of 10 years in the auto parts business and recommend the Dorman stat with no reservations. ... show more

    • Fixed my Truck cooling issue.
Thermostat works good, be aware that your engine temps will be 20 degrees higher due to a GM emissions change. Colorado and Canyon thermostat location sucks!! 1/4 inch drive sockets are highly recommended to change this part.
