GAP has the Merchant Automotive 10428 Engine Coolant Thermostat Kit that will replace the stuck thermostats in your 2001-2010 GM 6.6L Duramax. A blocked thermostat could be the cause of your Duramax diesel truck not heating up or overheating. The thermostats on your 2001-2010 Duramax 6.6L V8 truck can become stuck open or closed over time, creating heating and cooling troubles. To complete the installation, this thermostat kit contains the front and rear thermostats, as well as the oil fill tube seal and upper radiator pipe seal.
The front thermostat on a Duramax Diesel engine is symmetrical in shape and placed in the forward position of the thermostat housing. When the temperature reaches 185 degrees, the valve opens, allowing coolant to flow to the radiator. On a Duramax Diesel engine, the rear position thermostat is placed near the fire wall. It's distinguished by its offset design and built-in bleeder valves. At 180 degrees, it opens, allowing coolant to flow to the radiator.

Great toy
Great for an aggressive chewer. I was pleasantly surprised this toy lasted months with my dog chewing at it. Its one of his favorite toys! It cleans easily rinsing in the sink or running it in the washing machine &holds up very well.

Dogs love it
This our second one. The fogs destroyed the first one. Good toy and great for applying peanut butter in the grooves.

Cute durable dog toy that my puppy loves
Color: Blue, Size: 8 IN
This small light weight dog toy is very durable, super cute, and my dog loves it. My dog tears everything up but he hasn't made a dent in this; very durable and chew resistant. He seems to really like that it makes a lower squeak noise. I threw this in my cart at the last minute before checkout and I am pleasantly surprised with the quality. I would say this toy is worth the price; suitable for small to medium sized dog.

Nice toy for a bigger dog
Color: Gray, Size: 6 IN
My little rescue chihuahua has exactly one toy he can make squeak. This one is cute and he did try, but no luck. I have two large baskets of toys I've bought in the 3 years I've had him. He is only able to make one squeak. He loves it to death because he loves the squeak. It's a hedgehog that I will try to find on Amazon and replace. Poor little dog just has a very small mouth.
