Thread: Poor Cabin Heat - Defender 110

They don't have a heater tap do they? Don't they have hot water through the heater core all the time and just mix colder air with the (supposedly) hot.

Yeah, you're right Hymie. My 130 has this arrangement. What may be a factor also is coolant level. The heater core is the highest point of the cooling system and it'd be real easy to get an air lock'

The Pomms have got a blind sort of arrangement that goes over the grill that covers half the radiator. Worth a try. Cover half the front of the radiator and see if the heater works better. The poor old thermostat is probably working overtime at the moment on, off, on, off etc.
I used to stick a piece of ply between the grille and the radiator on my old series 2 in winter, stopped me wearing out thermostats, no kidding they used to break with the continual turning on and off.

Bloody Jindabyne. Ice, snow, blizzards you'd have to be crazy . Darwins nice this time of year.

Give the heater hoses a feel when it's up to temp they should be red hot if thre not the core could be blocked and make sure the heater flap is open of course. My heater just about melts the windscreen

Step one is to adjust the hot/cold flap to make sure it is tight to the hot side.

hi all

thanks for all the replies,

the hoses get, the coolant is topped up propery, the cable is well adjusted,

i think it is a combination of a few things, as on a drive to cooma in warmer weather it was pretty good, it is just the 5.30am starts in -5 or -8 that is is virtually non recognisable,

i think it is due to the air coming from the outside all the time and no option for recirculating, and the pretty poor air flow compared to any other contemporary car, also the distance of the heater core from the cabin, the large cabin compared to the small amount of air being blown in, the leaking/rattling rear windows,

basically it is as agricultural as the rest of the car, a 50yr old design from a country where everything is pretty dodgy, hehehe,

of course the heater would work well in darwin

bye all

There is an accessory I have seen for the heater inlet itself - basically it bolts on and is like a mini 'ram head' like on the snorkel.

The heater itself will only get warm, not hot as such. I found that once I had added insulation and carpet to the cabin of mine, it made a huge difference. But it still is nowhere as good as the missus' Prado.

The cover on the front of the radiator is a good one. There is an after-market one that has a radiator protector and a blind in the one - basically you can roll the blind up and secure it, and it leaves the protector there.

Lastly I always warm my old girl up for a good 5-10 minutes before getting in it. Basically I start her up and then go make myself a coffee (traveller). But I'm guessing you do that anyway.

hi,

unfortunately i wake up, ignore the alarm for 15-20 mintues, then just climb into my clothes, get out start it up and after 15-20 sec of idling have to drive off otherwise i will be late! hehehe, altho even the manual instructs the owner not to warm up, and i dont push it for about at least 5km, see ya

Something else to check is to see if you have a load of crud in the heater itself.

If you've not already done it, reach under the heater unit in the engine bay, grab hold of the rubber bung and rip it out. This bung is often the cause of build-ups of silt, etc... which then prevents air flow.
