Buying Guide For Best Coolant For Duramax Reviews In [2022]

Humans have always used liquid to keep things cool. That is where ice comes from. But electronics don’t work well on it. Experts have found that, on hot days that are under 40 degrees F or 8 degrees Celsius, coolants that are 70% water and 30% alcohol work best.

However, that works fine with electronics because the electronics won’t burn out. It is too bad that it won’t work on diesel engines burning diesel fuel, because if it did the environment would be much cleaner than it already is with air pollution.

Precision Parts Black Silicone Upper & Lower Radiator Coolant Hose Kit for 2011-2016 Chevy Silverado or GMC Sierra 6.6L LML Duramax Diesel. Currently there are no listings matching your needs. There are plenty of options for upgrading the upper and lower radiator coolant hoses on your 6.6L Duramax diesel engine in your 2011-2016 Chevy Silverado or GMC Sierra because you no longer have the factory color-matching hoses.

However, if you opt for either one of double OE or aftermarket coolant hoses, they will eventually leak right at the factory crimped ends. This is due to the higher pressure and temperatures of a diesel radiator verses a non-diesel sedan radiator. It comes as a result of the plastic being less durable, succumbing to greater mechanical stress, and undergoing thermal cycling quickly.

The Mishimoto MMHOSE-DMAX-11BK Silicone Radiator Hose Kit is light weight and high grade silicone and has a max temp of 330* F. Actually, most people underestimate the danger. Each hose is made up of a red silicone jacketed around embedded heat resistant inner fibers. The length of the hose is enhanced by its thickness.
