Car Forum / Land Rover Cars / May 2008Land Rover Defender Heat problem
hi My 1990 110 Defender has just started giving off heat from around the gearbox floor/transmission area. It really gets boiling. Does that mean i have to change the transmission fluid? There are no obvious leaks underneath the car, and overwise it drives ok. But driven for any amount of time and above 50mph, the heat really starts to rise. Anyone experience similar problems? cheers Mike > hi > [quoted text clipped - 13 lines] > > Mike I would think evryone that ever bought one will reply yes, they all get hot round that area. Well, every one i have had do.  SignatureNige, talking utter shite since 1967.

Well, every one i have had do. Mine gets hot, but never hot enough that i cant touch it. When was the oil last changed?

[quoted text clipped - 7 lines] > > bmc Mainly because the box is very close to the seat box, and being a defender there is no 'trim' there :) So when the box gets hot, so does the car! I like to think of it as an extra heater for the winter - Its a good place to store gloves ;) SignatureMark 1996 90 300tdi 1987 RR V8 EFI 2007 Golf GT http://www.mozilla.com/firefox/ - Firefox Rules! http://fireftp.mozdev.org/ - FTP Plugin for Firefox http://ietab.mozdev.org/ - IE tab.

Good thing my 90 doesn't get boiling hot, just a tad unpleasant.

[quoted text clipped - 9 lines] > > bmc There's a lot of friction in the gearbox, some of it actually designed in, (synchros for example), which can be increased by insufficient or incorrect grade of oil, and all the heat from the engine compartment ( rad, engine and exhaust/turbo etc.) flows past that area as well. Martin > hi > [quoted text clipped - 13 lines] > > Mike Exhaust heat soak is very common - and is really noticeable starting from mid-spring. Is your seat box getting hot? > hi > [quoted text clipped - 13 lines] > > Mike I used the exhaust wrap on the manifold (Kato) to reduce the under bonnet temperature no reason why the other kit shouldn't help with the 110 http://shop.agriemach.co.uk/default.php?cPath=0_7_80 Derek Disco 300Tdi Miles Disco 200Tdi Kato People Hi, we get the same kind of problem here in Greece also, especially on Defenders fitted with the V8 engines (3.5 up to 4.6) The solution we have found is the following. 1. Exhaust wrap on the exhaust manifolds up to and including all the exhaust system up to the middle box. 2. Heat reflective material attached on the outside area of the gearbox tunnet and seat box area (a very good material is the "barrier mat" from Noisekiller, mind you I do have an interest since I am their Greek representative and distributor. Cheaper heat reflective materials can also be sourced from hardware outlets such as Macro or stores specialised on insulation materials. 3. Aluminium foil glued on the inside area of the seatbox. A VERY CHEAP and easy thing to do. Just use the ordinary kitchen aluminium foil and spray glue. 4. Open three or four holes left and right of bonnet close to the area where the hinges are but on its sides. This way the heat from the exhaust manifolds will find this way to escape and will not travel through the gearbox tunnel. 5. Fit a 74 degrees thermostat on the engine. Hope this helps Take care Pantelis > > hi > > [quoted text clipped - 22 lines] > Disco 300Tdi Miles > Disco 200Tdi Kato You are describing a 'new' issue, now the same old hot tranny tunnel most 4x4's have from my understanding of this post. I would be checking the fluid level in the tranny and t-case right away, if it's low enough in either to cause overheating, it will cause a failure. If you think it's time for a fluid change, then you should do so, but you should still check the fluid level first. This will let you know if you have a leak someplace that may need to be addressed. Lots of leaks are so slow that using a liter of fluid a year is not hard to take vs a complete tear down to fix it. Cost wise anyway. Some leaks are easy to fix.
