Never really looked into my wife's SUV engine bay for any mod. But that day battery konk and went to make claim as the Century Ultramax is 21 months warranty and konk at 17 months. When open hood, spare part shop mentioned battery very hot, so while letting it cool, I checked out the engine bay and found the radiator fan actually blowing directly at the battery and air intake is just next to it. Looks like need to do some heat shield after reading this post....:biggrin:

Okay, last few days doing the battery heat shield for wife's SUV. Search around for something to DIY with. Household kitchen aluminum foil was found to be too flimsy. Finally found those aluminum backing for kitchen stove. Found them is those stores similar to Daiso at RM5.





The aluminum seems thicker but still not thick enough, so measure and cut cardboard.


Then cut aluminum to size


Then wrap cardboard with it


Then bent the board accordingly, remove battery clamp, fit in and clamp back. Using battery clamp to hold in place.

Before


After ( Can see radiator and fan right in front of battery)




Thanks for viewing....

me2kimi - doesn't the hose get heated up with the extractor being so close by?
plastic doesnt soak up heat very well and it doesnt dissipate heat very well either....

plus considering the speed of the air going through the hose, i think the amount of heat would be negligible....especially since its sucking directly at the front grill.

metal tubes on the other hand....

Where can I get PE foam? Is stationary store plastic boards suitable for heatshields?

You could've used the same sort of plastic boards (ordinary stationary store boards?) the others have been using since cardboard might soak up engine oil, moisture and degrade.

Did with what I had in hand. Anyway the cardboard is wrapped in the aluminum sheet, so protected from water, oil etc....:driver:

Should be no problem as long as it is not exposed. Y not tilt the shield a little bit to deflect the hot air?

quick question... can those stationery plastic boards handle hot air from the radiator fan... thinking of making one of these as my radiator fan is blowing hot air to my open pod

its worth the try coz it is kinda cheap. The best is that you add some more insulation or cladding to the plastic board (maybe rubber or the best is PE foam / fiberglass)

Firstly not much space and secondly I am using the battery clamp to hold it in place...:driver:

It appears that Lamborghini have filed a claim with the trademark office for the name ‘Aventador,’ leading to the mandatory speculation that it could be the name for the Murcielago’s replacement.

A select group of customers were treated to a preview of the new raging bull at Sant’Agata recently and word is that the Lamborghini Aventador...
