Product Details

The Mishimoto Low-Temperature Thermostat is engineered as a direct-fit replacement for the stock thermostat in Dodge 5.9L Cummins engines. This precision-manufactured thermostat features a lower activation temperature of 174°F compared to the factory unit's 180°F opening temperature, allowing coolant to flow through the engine sooner for more effective temperature management.

Key Features:

  • Lower 174°F activation temperature vs. factory 180°F for improved cooling efficiency
  • Direct-fit replacement for OEM thermostat—no modifications required
  • Helps reduce and maintain lower engine operating temperatures
  • Ideal for extreme towing conditions, heavy loads, and warmer climates
  • Prevents engine overheating and potential internal damage
  • Backed by Mishimoto Lifetime Warranty

This low-temperature thermostat is particularly beneficial for diesel trucks operating under demanding conditions where maintaining optimal engine temperatures is critical for performance and longevity. By allowing coolant circulation earlier in the temperature cycle, this thermostat helps protect your Cummins engine investment while ensuring reliable operation when you need it most.

so far so good

Happy Halloween

It was great, you had excellent prices, and the 2nd day shipping was better than most competitors.

Quick note easy

Quick and everything was easily found.

Easy

Great

Autoplicity had the lowest list prices I could find anywhere for KC hilites! I was only going to get one pair, but the price was so good, I bought two! Shipping wasn't free and that's my only complaint. Regardless, it was only 12 dollars for a 300 and some-odd dollar order. Shipped in 3 days; should arrive soon!!!

Great deals can be found at Autoplicity. I was a little hesitant at first since I never heard of them. Took a chance after reading the reviews and was very satisfied with their price, customer service, and speed of shipping. Thanks Autoplicity!

Really helpful to be able to see competitors price to confirm that Autoplicity has the lowest price.

Easy and cheaper than everywhere else!

I am extremely satisfied with Autoplicity in terms of service, price, and shipping. I was shopping for a set of N-FAB step bars for my truck and was ready to purchase from Amazon when I decided to look around to see if there were better prices. I stumbled upon Autoplicity and was surprised to see their price on the bars. I checked with their online chat customer service to confirm that they would fit my truck and that the price was for a pair of the bars and not just one. (That's how low the price was!). I then placed my order and the bars arrived at my doorstep 3 days later! Autoplicity gets an A+ in my book and I'll definitely be coming back.

My Superchips Cortex arrived within a few days of order and by far was the best price arround. Product arrived in perfect condition and worked as described. Great deal. Order #10984

So far the process is going well. Let's see if the product is legit and how long it takes to ship.
