I want to fit a noisekiller under my bonnet (if I can get someone to send to Germany) but there doesn't seem to be much clearance
If it ends up pressed down against the engine, won't it cook something (and/or make it louder)? Cheers Matt Tell someone you love them today because life is short. But shout it at them in German because life is also terrifying and confusing... |

I guess you mean the NK "Blanket"...
I already have the NK soundproofing that is self-adhesive under the bonnet, and it seems to make a small difference. Instead of NK blanket, I am waiting to see what happens with this: http://www.defender2.net/forum/topic8633.html If the 2.2 is quieter, and the engine cover makes a difference (and fits!) so long as the price is reasonable this looks a good bet to me... I assume this will give good access to check and top-up oil etc... Waiting to see when they come out... Defender "Puma" 2.4 110 County Utility (possibly the last of the 2.4's) |

Yep, the blanket 
Did you fit it under the whole bonnet underside or just the bulge? Did it make a significant difference? If not, I won't bother as it will cost me a king's ransom to get it shipped here

I fitted the under-bonnet NK insulation and it made a small but noticeable difference. I then fitted the NK blanket and it made a HUGE diffference!

Mine's apparently arrived at home this afternoon, I'll be fitting it later
In theory if your cooling system works ok, it shouldn't overheat your engine. The heat rejection provided by the coolant/radiator is massively (as in hundreds of times) greater than the heat rejection directly off the top of the engine, which is where the NK blanket goes. After all modern engines (like the Td5 etc) already have a foam/plastic cover on the engine. Plus I figured what with living in the UK and driving a 110 which rarely sees a heavy load, it should be fine. Particularly as the massive viscous fan on the engine is waaaaay OTT for most applications. I used to run my old 90 through winter without it  |

Yup I only have the under bonnet stuff - looks like this:

Sorry for my "thickness" but what's the difference between NK "insulation" and "blanket"? Does the "blanket" stick under the bonnet or sit on the engine? Any chance of a pic of a fitted blanket and perhaps the website of the one you bought? I can only find self-adhesive stuff you cut yourself.

The "Insulation" is self adhesive and sticks under the bonnet as my photo above

The 'insulation' is an adhesive-backed foam covered in foil, which you stick to the underside of the bonnet as in the photo above.
The 'blanket' actually straps to the engine (i.e. stays in place when the bonnet is lifted) and is made of a sheet of lead between two foam pads, all encased in a fabric bag. There are eyelets to hook it onto fixtures to keep it still. I'm guessing on more modern Defenders (Td5 onwards) you'd have room for one but not both - although I haven't tried it so I don't really know. |

Insulation sticks to the underside of the bonnet.
Blanket goes over the top of the engine. I went the full NK route on one of my TD5's with insulation all over the place but the blanket made a big difference and I never cooked the engine or any ancillaries. Steve.

Great - I'll be getting a blanket somehow 
Any advice on the size? The website says "Small 500x500mm, Medium 750x500 and Large 925x500". Do I want it over the entire engine compartment? Cheers Matt Tell someone you love them today because life is short. But shout it at them in German because life is also terrifying and confusing... |

I shouldn't worry about overheating a Defender - your not in Africa!!
I took the viscous fan off my TD5 a few weeks back and the temp guage hasn't budged from normal position. Includes motorway driving, 3 hours green laning and day to day driving. Steve Defender 90 TD5 Station Wagon

Thanks - you've convinced me
but how big should I go (pfnaah, pfnaah)? Noisekiller do them in 500x500mm, 750x500 and 925x500 - not sure if I should cover the whole engine compartment or just the engine...y bit (must be a technical term for that  ) Tell someone you love them today because life is short.
