Thread: LT95 extended cooling sump

Not sure if a cooling sump is required, but you can buy one from roverdrive (see link)

Unless I'm misreading it, thats only for the LT230, not LT95.

Steve

Looks that way Steve

Thanks anyway Boj

Spoke to a long time LR expert here in Vic who knows his stuff and he says they were made but he hadn't seen one for a long time

Marks 4wd Adaptors may have made them?

Maybe I just beef up the heat proofing under the seats

AFAIK steveG is correct it is only the lt230 ... you are probably referring to these threads ...

Mine is also hot in that region but I do not drive much

Pete,
Rare as Rocking Horse poo !!
Marks adaptors made them-- looong time ago.
I'll post up a pic of mine if it will make you go green with envy..
( it's on the Chev Tray, not the Isuzu though)

Still gets unbearably hot in the cabin though. I recall visiting Toorak Tractors some years ago & he was modding a 110 & getting a better airflow thru down there. He was opening up the inner front guards from memory.

Get some pool hose and a couple of those rectangular to round storm water adaptors, mount the square to rounds under the front bumper and run the hose to the top of the bell housing each side. Presto, air cooled transmission hump. costs bugger all.

Exactly what my racing car mate said.

" Get some air moving over the hot bits stoopid. Best form of free cooling available"

I know it feels as if the heat is coming off the transmission, but I strongly suspect that most of the heat actually comes from the engine - the hot air from the engine is pretty much channelled alongside and over the gearbox by airflow blocker called a gearbox crossmember. Some air goes below it, but most of the hot air, preheated by the radiator, heated by the external surfaces of the head and block, and superheated by the exhaust manifold, is confined by the bonnet, inner mudguards, chassis, and sideways sump extension (especially on the left) to flow through the gap either side of the bell housing and between the gearbox and the floor/transmission tunnel.

If you think about it for a moment, of the energy from burning fuel, about 25% is converted to mechanical energy, of which only 1-2% is lost as heat in the gearbox. The remaining 75% remains as heat and is transferred by the cooling system to the air flowing past the gearbox, except for a relatively small proportion that is still retained in the exhaust.

This strongly suggests that improved gearbox cooling will not have a noticeable effect on the floor temperature! (It might help the gearbox though, as the 'cooling' airflow round the top and sides of the gearbox is probably above coolant temperature in hot weather)

As suggested, managing airflow is likely to give better results (or simply use thermal insulation).
