How to Hold Exhaust Temperatures Down


Header Coatings Hold Engine Temps Down

Anytime you modify or “hop up” your engine to get far more horsepower it will create far more heat. That heat can travel by way of the engine bay and into your car causing discomfort. 1 way to drop the temperatures of your engine bay is to preserve your headers or manifolds from radiating so substantially heat. External coatings can assistance, but if you want your headers bare you may well not want to coat them and hurt the look.

Eastwood Internal Exhaust Coating

Internal Header Coating is a important step to creating a customized or efficiency primarily based car. We recommend coating the inside of the pipes with Eastwood Internal Header Coating for two factors. The 1st is simply because it keeps the heat from the exhaust gases inside the pipes as opposed to the pipes radiating heat and raising below hood temperatures. By coating the inside of the pipes it provides a hi-temp barrier among the exhaust gases and the metal of the headers.

Exhaust Systems Rust From the Inside Out

The second purpose internal exhaust coating is essential is that most exhaust systems rust from the inside out simply because of the moisture that a cold engine can solution when you 1st run it and the adjustments in temperature. By coating the inside of the pipes of cast iron or steel pipes you will seal the bare metal up from rusting and let them to final a lifetime.

Application is straightforward, start out by making use of an air nozzle and blowing any debris from inside the pipes out. Then you can spray PRE Paint Prep Can to clean out the pipes and dry with your air nozzle.

As soon as the PRE is dry you can attach your extension nozzle to your can and preserve some rags with PRE Paint Prep subsequent to the function region.

As you get close let off of the nozzle and pull it out to move to the subsequent pipe. The conical spray pattern of the nozzle really should cover the majority of the inside of the pipes but you can rotate the headers, manifolds, or pipes about although the paint is nonetheless wet to assure it covers every single square inch.

Immediately after almost everything is coated you can stick to up with a rag and PRE to wipe off any more than spray or runs on the exterior of the pipes. If the paint is nonetheless wet it really should eliminate conveniently, but when it dries it is Pretty complicated to get off. Immediately after six-eight hours you can set up the pipes and run the car or truck. The 1st heat cycle will completely remedy the coating and then the engine can be run as typical.
