Heat build up in cabin

[eckwalsh]

Hi Guys.
I have an 08 defender and on the w/end did a trip to Canberra towing a trailer with 3 motor bikes on it. On the way down seemed ok. Mind you it was pouring with rain the entire way. On the way back however when the day warmed up a little ( but not hot) the floor in the front got hot and warm creating warm air and even the handbrake lever was too hot to rest my leg against. I had to run with the A/C on just to cool the cabin down a bit.
Is this normal as my TD5 did not do this or is there something i have to do to prevent this happening. I did notice that the exhaust seems to run fairly close to the floor nowadays tho. Any wadvice would be greatly appreciated.
:confused:

All I can say is mine doesn't exhibit this and I did 30km of sand driving on Sunday in extremely hot conditions. Also when I drove the Defender back home from Melbourne after buying it I never had this problem in the 4,500km trip.

Have you had a look underneath to check nothing is touching the exhaust?

[Blknight.aus]

climb under your 08 fender and have a look at how ford solved the problem of the exhaust heating up the passangers side foot well.

Yes have had a look and doesnt appear to be anything touching. Have driven it 13000 km's already and have noticed it once before. again when towing a trailer ( and not a heavy one) and on a warm day. Driving with a load in or hard driving which i often do doesn't seem to cause this but towing a trailer for some reason does. Bit of a mystery.

I would think its ok. My TD5 floor and tunnel gets very hot when worked hard.

Should have mentioned, the first 4,500km I did in mine was towing 1.5t of camper trailer.

It does sound similar to the old problem the Tdi's have with the exhaust heating the passenger's foot well.

As for warm day's It's never much below 25C up here and Sunday down the beach was about 40C and in very soft sand.

The hand brake's not sticking on at all is it? When you notice it next time see if the drum is hot.

Definitely a mystery and please post up any resolution it case it occurs to anyone else.

They didnt do too much. Just a bit of insulation here and there. A flimsy heat sheild on the drivers side.Bit budget i'd say..lol

Even my old 200tDi does it mate. And it gets real uncomfortable too. Especially considering I don't have any carpet, matting etc. It's just straight floor!

It is something I'm looking to rectify in the near future. Just trying to work out what to use.

Will check the handbrake next time. Didn't think of that. Might be the motor bikes. Only seems to do it when i'm towing them..lol.
Will post up anyresolution i get tho. Thanks for your help guys.

Refreshing in a way to see it's not just mine tho. Didnt worry me to much just a matter of winding the window down but the boss (missus) didn't go much on it. As they say happy wife, happy life..lol

[Blknight.aus]

so you didnt notice that they cured the heating of the passangers side floor by putting the exhuast under the drivers side.

what your describing is perfectly normal and has, as far as I know been a landrover thing from the series I.

Yes i noticed the central heating for the driver..lol. Guess i never noticed it on my 94 and 03 defers. They also had the windscreen vents too which were nearly always opened too. Not to worry. Just makeing sure there wasn't anything wrong.
Thanks for your help guys;

My wifes's solution when we drove the Series III across from Roper Bar to Booroloola was to sit with her feet in a bucket of water. :D

I remember having the same problem on my Series 1! And they had heat shields on the exhaust pipe (which gave a lot of trouble).

Grave dig.

So I was wondering if many other Puma owners get the hot handbrake/seatboxes syndrome.

Mine seems to get pretty hot - particularly during long trips in hot weather.

Feedback anyone?

[Boots]

Yes, my 07 130 cabin floor gets very hot when driving on the highway at 100Km/hr +. It seems that heat is conducted (I think) along the chassis/body components and the seat boxes and the rear footwell area get quite hot unless its a very cool day. I operate the airconditioner to alleviate the heating. It would be great if a technical solution could be found.

Cheers

Boots

[stig0000]

take the center muffler out, will let the heat 'flow' out alot better

[stace70]

my 130 has only 12000km on it and has done it from day one......mine also had the handbrake drag issue but they replaced the drum which fixed the issue (or at least the noise so I assume the issue)....it still does it but like you have indicated only when towing the trailer

Hi All

I remember when two locals came back with their 2A LWB hardtop from their extended working holiday around the other island, (about 1970) I think . :wheelchair:

Their cure for heat was to line the floor with polystyrene offcuts, I would say to ride in that landrover would have been awkward, the chaps knees would have been up above his ears ! :p
one of the brothers took up some of that insulation on the floor, showing the floor panel with the remains of his thong's plastic sole stuck to the floor!! :eek2:

Cheers Arthur

[Bundalene]

We insulated the underside of our Puma as per the post below. I can't advise at this stage as to the effectiveness as the car isn't on the road yet. I think it should make a difference.

Use window to let heat out.

Use flaps to let air n. Oh that's right you haven't got any :P

Chris go some compressed foam and then come black rubber reinforced with canvas through the middle kills sound and reduces some heat, then go for a couple of kick plates on the wings to bulkhead allowing free air flow.
Andy

On the 08 defender it's not the gearbox getting especially hot under strain is it ?

[justinc]

I have an '09 130 that I am trying to work on a solution for this problem at the moment. I'll post any progress/ ideas when I get them.

Meh. I just turn the AC on...:angel:

To be clear - In my case I'm not talking about towing conditions, just use in hot weather.

I'm, particulalry interested in other Puma owners experiences (though all feedback is appreciated).

Erich

Probably unecessary - given the thermo nuclear-like power of the Puma's heater.

[Blknight.aus]

Im going to suggest the morris solution.

duplicate the bends of the exhaust in ehxuast tube thats an inch over the nominal exhaust size then cut it in half and flare it at the engine bay end so cooler air from the fan is forced along it and mount it up onto the existing exhaust with u clamps.

:D We have our hot days too Erich! In fact the first week we spent here all those years ago was mid to high 30's. Coming from WA we thought 'What have we got ourselves in for???':p

I had a chat to our A/C fellows today about the 110's system, he reckons I should be fitting a second evaporator in the rear and run a twin system due to alll the windows etc. I have a small rear evaporator from a HJ61 Sahara that will fit nicely in the rear corner...:)

JC

[davep130]

My 08 130 with 25k on the clock has the symptoms and recent highway running for 3 hours left the cab unbearable with out AC.

Load was not great just bikes camping gear and 3 people

I had a 94 110 single cab that was never anywhere near that bad.

Hope you find the solution JC :)

JCI have often thought of doing this also, if you do it please post up some pics.

Oops, it is an '08, on account of it being YOUR vehicle Dave:p

I have had a look under today, and have a few ideas about redirecting some of the airflow from the radiator and exhaust air, which travels back at highway speeds creating a low pressure area under the seat box etc, drawing a kind of vortices which just 'whirlpools' the hot air. At least that is my theory so i'm going to try and redirect the air rather than try and prevent the transfer through the seatbox and insulation, which is only effective if you are doing short runs. After 30 minutes or more of high speed driving, the heat will travel through into the cab anyway as it will conduct itself, albeit slowly, through the layers of metal and rubber matting. My feeling is to try and reduce the heat in these areas, rather than manage it after it has already appeared.

JC

[wrinklearthur]

Hi All

Wasn't there some work done a few years back about using the exhaust heat as a energy source for airconditioning ?
Silent Knight fridges worked that way, both electric and the kerosene types.
They were simple tough old fridges that took up a heap of room in the kitchen, when they played up, the fix was to bowl them around the backyard, they worked well after that. :eek:

Well I'd subscribe to that theory.

I was thinking along those lines yesterday as mine also gets very hot and just in the centre section between the boxes under the seats.

There is a "pocket" of space above the transfer case that appears as though it could be a good place for an eddy of air to sit. Some aerodynamic disturbance via a scoop might do the trick.

Watching with interest :)

JC I was just kidding

The A/C units from the rear of the D2 would also be excellent as they are pretty well stand alone. Problem is they are quite scarce.

[scotsmun]

My 08 svx heats up the underseat boxes very well ( i might put a raw chook and some veggies in the battery box), on a hot day the footwell gets nice and toastie.......i don't notice it because usually my head is melting because of the oh soooo cool glass sunroof inches above my nut......ye great idea , black defender with a glass sunroof:D and they gave me heated seats.....somebody in India has a sick sense of humour :D

[saxon]

I have a 08 130 mine also heats up around the handbrake area
spoke to the dealer when it went in for a service they know about
the problem and said so do Landrover but will not do anything about

Thanks for the advice. I actually did do something about it (original was posted in 08) finally - it starts here (http://cewilson.offroader.com.au/?page_id=311)

Solve the heat and noise problem in one go install the noise killer noise insulation kit and it does a pretty good job of reducing the heat. Can now put bare feet on the floor. Does a superb job of reducing noise as well.

yep ,,i got it ..............5 day plod thru high country few weeks back,saw me with a permanent left calf ,,cooked medium to well done ,,i kid you not.

Hey guys,
I too have a burnt leg from an over heating handbrake. I was considering moving the handbrake to the space next to the drivers seat. I understand it can be done with a disco handbrake. Has anyone done this conversion???
Cheers Sooly

[dennisS1]

Stick a bit of black foam pipe insulation over it, stops heat to leg problem and makes a comfy rest.

There's a Rangie conversion that's been around for a while

www.REEDX.net (http://www.reedx.net/landrover/mods/handbrake/index.htm)

One solution might be to add small 12v fans to the seatboxes. Pressurise the seatboxes with cooled cabin air, force the hot air out the drain holes underneath. Disconnect over winter.

Curing the symptoms instead of the disease I know, but food for thought.

Made in the UK can import it yourself from Soundproofing Products for Car Soundproofing | Industrial Soundproofing | Marine Soundproofing (http://www.noisekiller.co.uk/) , or some LR specialist importers import it one is Landrover Tuning :: Home (http://www.landrovertuning.com.au/shop/).
comes precut with each piece numbered and instructions of where to put it. Some pieces are self adhesive while other fit under the existing lining. My kit fitted very well with next to no trimming necessary. Its a big job to fit as it includes adhesive pieces to fit inside each door. Only drawback is you really appreciate how crappy the stereo system is now you can actually hear it.

[portafilter]

you guys dont have rubbing hand brake shoes by any chance? my 07 110 seat box and hand brake, if anything, is cool to the touch?! maybe rubbing shoes is heating up and conducting heat up the cable along with cooking the t/case and heating up the seat box?
i just replaced the shoes and redid the t/case output flange oil seal and etc as splines were leaking oil. i found the shoes worn down to the steel and when refitting the new ones the adjustment was REALLY sensitive, and i suspect the reason they were so worn was continual rubbing.
good new tho that after doing the leak and tightening the centre nut to the correct torque, not finger tight, the backlash on gear changes is gone.

just a thought.

Just to confirm - you're saying that you don't get any heat build up after say three or four hours driving (particularly on say a 40 degree day)?

[portafilter]

That may be different.
I drove to wye river from Melbourne and the hand brake was no hotter when I got there than when I left. There is heat in the floor pan but there but nothing like what other people have said they have. Lever certaintly isn't capable of burning my leg, I can rest my leg on it no problem.
