Heat Management Part 4

I am taking a step further into heat management, trying to create awareness on how important this can affect your vehicle in the long run from all points of view. The Radiator Relief Coolant will be here in a couple of days and I have chosen another product to be brought in. Below is a product called heat shroud by DEI where it can be used just about on any wires, tubes or hoses. These are a little bit pricey  but the beauty of it is that you can just strap it on with the velcro strap that comes along with the shroud. Unlike it's cheaper associate, no disassemble of tubes/hoses is needed during installation. The cheaper shroud will require you to remove all tubes and hoses from the car to slide it in the sheath whereas this particular type just lets you install DIY style.


You may ask why do I choose this to be sold? Below are examples and explanations to your question

Oil Hoses
If you have an oil hose close to your exhaust pipe, ensuring that it is properly insulated will really help. The exhaust gas doesnt heat up the hose and the oil that's in the hose which in turn increases oil temperature.








                                                                            Aircond Hoses/Tubes
 Regardless if it is rubber, or aluminium or even copper. The low pressure sure of the a/c system is to be kept at low pressure(cold) at all times. Heat radiation from your engine bay may heat this up, making your aircond compressor working a little harder for it to compress the gas going into the condensor. In particular, BMW E36 and E46 3series cars do have their pipes directly beside the exhaust manifold.

 Steel Braided Hoses
Steel braided hose heats up faster and gets hotter than rubber hoses. Insulate this, nuff said.
Certain hoses also have a teflon insert which may or may not melt at above 180 degrees celcius.

 Water Hoses
This is a case of the water hose probably being too near a heat source. This picture also resembles a slide-on type heat sheath(note, the difference between heat and shroud) where you have to dismantle the hose from the reservoir tank.

 Oil Hose
 Look at the location of this hose. This is probably a top mounted turbo where the return hose drops down through the two runners of the exhaust manifold. This HAS TO BE INSULATED. If the rubber hose ever touches the runner/manifold for a prolonged period, oil will touch the manifold. Fire hazard.







Unknown Hose
 Another case of a hose being too near the exhaust manifold. Another alternative is to also wrap the exhaust manifold with DEI Titanium Exhaust Wrap.

 Heat Soak Issues / Injectors
The owner of this car suffered from heat soak and resulted to insulation. The shroud is used to insulate heat away from the injectors, avoiding premature failure caused by heat.

Speedometer Cable?
Yes, no kidding. This is a Supra, having issues with melting speedometer cables from time to time on a single turbo setup. Problem solved!













Below are specifications of the heat shroud I will be bringing in :

Heat Shroud is made from a high temperature rated glass fiber fabric with an aluminized outer facing. Same as Heat Sheath but with the added convenience of hook & loop closure design along the open edges. Without the need of removing one end of connected wires, cables and hoses, simply wrap Heat Shroud around whatever needs protection and close edges.

• Versatility of fitting diameters ½” to 1-1/4”
• Convenient hook & loop designed edges
• Withstands 500°F direct continuous/2000°F radiant heat
• No need to remove wires and hoses
• Easily trimed to length
• Fireproof
• 1⁄2” to 1-1/4” diameters x 3 foot length

Price is RM200 per three feet, DIY installation. You all may think this is extra pricey, but for the built and meterial of it, inclusive of shipping and goverment tax, it's not so bad after all. Safety first. This is VERY important.
