Bonnet insulation

You can buy aftermarket contact insulation, but you cut it to suit - not a biggie....

try this mob

they sell underbonnet insulation - found them quite reasonable

Hi Sludgie, My Troopy's bonnet lining was non-existant and I fitted a sheet of 15mm foam with an aluminium facing on each side obtained from Clark Rubber. It did reduce some engine noise in the cab and has stood up to the engine heat OK.
However on testing, the foam can be ignited with a cigarette lighter although it self-extinguished on removal of the lighter flame.
I used another piece of this material to create a thermal barrier for my batteries. See Thread 91116 for more information. The photo below shows both the bonnet lining and the battery heat barrier.



As an alternative, there is a product called Dynamat Hoodliner possibly available from Auto-One or Opposite Lock in WA. (See below) It is probably more expensive than the Clark Rubber stuff but possibly a better product. I have just purchased, but not yet fitted, a similar Dynamat product to insulate the cabin floor and doors from heat and noise. This is a self-adhesive loaded butyl mat, not foam.

There are some pretty expensive acoustic foams intended for interiours....some are rediculously expensive and some have poor temperature and oil tolerance.

have a look in the marine discount suppliers like Whitworths and Bias.

They generally stock a couple of different versions that are intended for engine bays.

The purpose of the foil is to protect the foam from a bit of heat and from oils and solvents.
any thermal insulation from the foam is a minor byproduct.

Not sure how it compares to what is available elsewhere but about $70 to $100 a sheet about 800 x 1200 ish.

cheers

Sludgie,
If you are going to use tru-fit ring them as they are hopeless answering emails.

I had the tru-fit under bonnet insulation on my troopie and it lasted about 5 years before it started to fall to pieces. I just bought another piece from them after that time and replaced it. It is a bit of a bugger removing the old adhesive that comes with it.

Try and use your old liner as a template.

A mate recently replaced it on his 79series - just bought a new liner from Toyota. I can't remember what it cost him, but don't think it broke the bank.

Cheers
Phil
