Exhaust Vibration

Hi Guys

Another little niggle on the 1.8i that needs sorting the Exhaust is very buzzy at about 3600rpm and over gives vibration as well any ideas?

Hi Justin,

First check that all the rubber hangers are still intact, present and correct.

Then slacken off (not remove) any 'U' bolts or other clamps - checking that they are not under tension - then re-tighten.

It may be of course that some of the internal baffles are corroded due to condensation etc. and that the box(es) are rearing the end of their useful life.

My back box is living on borrowed time and buzzes a bit until it's warmed up, but even then the buzz only reduces in volume rather than stops.

It's due for replacement after the winter snow and salt is over - not a problem for you I think though, in SA.

Good luck.

Singvogel.

Thanks Singvogel

I will have a look as sugested. No ice and no snow here just soft sand and heat current temp is 36 degrees C A/C working overtime :lol::lol: I had a Toyota Hilux Doublecab 1990 model 4x4 with the solid front axil so freelander is bliss

You can improve the efficiency of your A/C easily and cheaply by insulating as much as possible of the cold feed pipe to the heat exchanger, which runs from the compressor up and along the edge of the engine bay, with the closed-cell foam pipe-insulation tube stuff you can buy at a DIY home improvement store.

The hot return pipe should be left uncovered to dissipate as much heat as possible.

Apart from the outside temp, the heat in the engine-bay, and from that return pipe routed right next to it, raises the temp in the cold-feed, which really needs to be kept as cold as possible until it enters the cabin.

You should be able to get the air coming out of the vents down to near 2degreesC by doing this - certainly under 5degreesC.

I learned this trick in Saudi Arabia where we had temperatures of 47C in July and August.

Caio,
