The plate above where a middle seat would go in the cab area gets extremely hot while driving! Is this normal? If not then why is it getting so hot?
Thanks
 
It's the plate above the transfer box, it's a defender 90

Then no ... that shouldn't get hot unless something is wrong somewhere. Mine has never got to more than ambient cab temperature.

I'd guess that maybe the exhaust has been re-routed, maybe the gearbox/transfer box is running hot, maybe no oil! It might also be pointing to a problem within the boxes, nackered bearings maybe ...

Have you felt how warm/hot the gear and transfer boxes are getting when the plate is hot? Take the plate off and drive around with someone in the passenger seat and see what's happening ...

Right. Not sure why you posted about in 101 and military, then?

That area shouldnt get so hot, but the transmission does get warm in prolonged operation.

Try what Paul suggests. ^^^^^^^^^^^^. But if the box is really dry or very worn, noise may identify the issue anyway.

Infra red thermometers, which you can point at the engine or trans, are only a few quid these days. They give a pretty accurate temperature reading of specific areas, which can be compared with manufacturers data. We us them to diagnose cooling issues on boats.

Yes not a bad shout that, I may give that a go if it keeps happening. It's leaking oil from under there somewhere so it's in the garage on Monday, hopefully they'll sort it.

Thank you turboman for your sensible answer this time :)
I posted in this section because it's a Defender 90 ex MOD without all th civilian upgrades etc ( Maybe I should have stipulated that at first), unless that still leaves me in the wrong section?
 
Looks fairly military to me

My first answer was sensible if it was a 101 Forward Control. But in fact the forum is confusing, 101 and military is a confusing title! :)
It is always worth stating the type pf vehicle in your first post, though, saves confusion.

Pauls suggestion of driving with the cover off is a good one. Try getting one of the IR thermometers. Then get a friend to drive around, cover up, and point the thermometer at different areas of the engine and trans. Will give you a good idea of what is going on.

Something like this would be well suited. They are good, I had low expectations when I first used one, because of the low price, but in fact it was very good when tested on known heat sources.
