Sunscreen For Your Truck’s Guts: Thermo-Tec Cool It Products

Heat is the one thing we constantly fight on every vehicle we have. It destroys transmissions, kills radiators and engines, fatigues axle gears, burns through important wiring, overheats vital parts, and makes your vehicle too hot to sit in sometimes.

If you’ve got some experience with customized vehicles, then you are likely no stranger to some type of heat problem. Having your vehicle properly prepared for the heat its parts will generate is imperative to the longevity of your vehicle. In minor cases, heat will prematurely wear things out on your vehicle. In major cases—say, one in which a wiring harness catches on fire—it can cost you your ride.

Thermo-Tec has built an entire company around preventing heat damage, and there is no shortage of enthusiasts who need to think about a little better heat management.

We asked Thermo-Tec to send us a few samples of their Cool It wiring sleeves, header wraps, and heat barrier products—welcomed protection that we used up too quickly on our own project vehicles.

07. Header Wrap is a time-tested method of keeping heat from radiating out of the exhaust system before the tailpipe tip. It can be used any place from the headers to the tailpipe, but it’s most effective when used around the headers so the hot gases (with decreased density) exit the engine most quickly.

Cool It’s Exhaust Insulating Wrap has a proprietary coating made by Thermo-Tec known as Thermal Conduction Techonology (TCT) that conducts heat across the wrap’s surface.

08. We wrapped our headers and some spots where the 2.5-inch exhaust tubing gets close to the body. We also got a couple packs of Cool It’s Snap Straps to hold the Exhaust Insulating Wrap in place.
