Function of this part

The cooling system maintains proper engine operating temperature using components such as the radiator, charge air cooler, fan drive, and water pump. It removes excess heat from the engine and sometimes from charge air and transmission oil.

Why this part matters

Overheating can quickly damage an engine or transmission. Keeping the cooling system in good shape is essential for uptime, especially on heavy loads or in hot climates.

About the brand

Mack is known for building tough trucks and components for construction, vocational, and highway fleets that need reliable performance day after day.

Nice to have
Color: Brown, Size: 10.2" x 8.4" x 1.8"
Good: It's a good sized leather tray for the price. I'm able to keep my keys, wallet, tv remote, and watch flat within the box. There's not much else to say, it's a leather tray, it just... works. It gives me piece of mind knowing that I'll always find my accessories and belongings nicely tucked into this tray. Bad: I'm a fair reviewer, if a product wows me I'll say it wows me. This does not wow me in the craftsmanship department. The product I received contains the leather tray and a leather "floor". The leather floor is a separate piece that sits at the bottom of the tray which completes the complete leather look and provides some cushion to the things inside. This leather floor did not fit perfectly within the confines of the tray. One edge sits slightly tilted upward. To be completely fair, this is a very easy fix. I assumed that the stitching was simply applied too tightly and causes the floor to 'crunch'. I simply reduced the tightness of the stitching and it's perfect now. However, I cannot give it the full 5 star rating I wanted because not everyone is keen on solving issues like this. When people order things, I assume that most people would like a product that looks and feels great straight from the box. Verdict: Would still recommend. Despite this being a somewhat niche product it really helps with quality of life. I no longer have to go looking for my keys, wallet, or tv remote between my couch cushions. I know exactly where I'll find them every time and this saves an exponential amount of time in the mornings. As a bonus, the color is really nice and dark chocolate brown which goes with most things and leather is just a nice luxury to have.

A perfect catch y’all
Color: Dark Grey Shagreen, Size: 10.2" x 8.4" x 1.8"
I use this as a catch on on my dresser and it is sturdy and provides a bit of chicness and beauty that I can just throw all of my things in and keep it keep myself organized. It is leather, and well constructed so you can’t go wrong. And if you spill anything, just take a wet wipe and wipe it up. I highly recommend.

Holds stuff nicely - classic addition for the bureau!
Color: Brown, Size: 10.2" x 8.4" x 1.8"
Ordered this as a gift for my son, who always seems to have a small pile of "stuff" accumulating on his bureau. He is not a fan of leather, so this tray was perfect! And it was a great value for the price. Ordered it in brown. It has a nice feel to it and (color-wise has a rich tone). Perfect for his keys, spare change he finds in his pockets, extra watchbands, whatever. Makes a great gift! I definitely recommend!

Nice design
Color: Dark Grey Shagreen, Size: 10.2" x 8.4" x 1.8"
The design is nice and doesn’t take up too much space, but it holds a lot more than I expected. The materials feel sturdy and quality, and it looks great. It's made it so much easier to stay organized with our keys and wallets.
