Defender 200tdi Exhaust Heatshields...Thoughts please.

Hi all,

Ive just ordered a new downpipe for my 1992 200tdi 90 and discovered
that it *should* have 2 heat shields on it, one (NTC4833) which goes
over the turbo and most of the way down the down pipe between the
exhaust and the bulkhead and the other somwhere towards the end of the
downpipe.

Mine has the remains of the heatshield immediatly over the top of the
turbo but doesnt go downwards and the other is just missing.


So... Im assuming they dont really serve any great purpose as ive done
about 10,000 miles without either of them?

However, as a side note my engine still shows as running hot (needle
towards the end of the white on the gauge) after having a new
radiator, thermostat, viscous coupling etc. Compression good and no
water leaks or steam.

Is it possible that the lack of these heat shields is causing a build
up of heat under the bonnet and thus showing a high temperature
reading??

If above is not likely do the sender units or temp gauges go out of
calibration after a time??

C'mon guys... whats the general concensus? Are these heatshields of
any real use? Should I replace my missing ones?

I noticed the other day one of my brake pipes runs close and parallel
to the downpipe? But I seem to be able to stop!

A heat shield reduces radiated heat, it they are there to reduce the
heat in the footwell radiated through the bulkhead then you could get
away with not bothering with them, if there are brake/clutch pipes
there or relays and suchlike then I'd expect the heat shields are
there to protect them and so I'd replace them.

if the price of the heatshields seems expensive you could easily
fabricate something and mount it on the bulkhead.

Thanks very much Mark.

The engine side of my bulkhead has what i can only guess is a heat
reflecting / sound deadening material stuck to it, put on by the
previous owner - To describe it you would have to say its about an 8mm
black foam with tin foil on outside.

Undeneath is a different story though. Fabrication time at the
weekend me thinks!

Thanks

That's standard insulation.
In answer to your question, the heat shields are there for a
reason (car makers never fit anything that isn't necessary),
however for the UK climate it's quite possible that they can
got away with. Certainly on my 110 which gets well and truly
used there is no general overheating problem, except that
occasionaly after good two/three hour thrash down the
motorway I loose 90% of the clutch until the fliud cools down!
Backing off speed by 5mph is just enough to stop the problem
though.
