I have this problem with the Discos cooling system TD5, it's to bloody efficiant, to the point that it won't sustain enough heat in the coolent due to controlling flow of the coolent to heat the fresh water pumped into the heat exchanger for a hot shower.

I have plumbed it in where it would normally go, before the heater (hot coolent into exchanger) and after heater (coolent) out of exchanger, this is how i had it in my last vehicle and it worked brilliant.

I have been speaking to Helton, who have been very helpfull i must say, thanks guys and there suggestion is to plumb into the top radiator hose directly, where the coolent flow never stops (coolent flow before and after heater only happens when heater is on and the engine is reving at over 1500rpm) and is controlled by the ECU so can't do anything about it.

Is the Landy alone in this or are all the new electronicly controled Turbo diesels like this (ie)3.0ltr Patrol, 3.0ltr Jack.

Gday mate,

Dunno whether it's the same kind of system, but my glind is damn hot. However, if I want to heat up real quick, I just run the water through twice, then pump it from the drum. Easy!

Cheers mate,

Hey Redback , I believe its actually a fairly common thing on modern diesels.

The solution as told to me was to run it in paralel (sp) to the system , not in line with the system. You then run a seperate Heater valve for just the HE.

Shed Guy , just to run it like that on His Diesel Prado.

Thanks Graeme, yeah the Helton is designed to be run in parrallel to the system which is the way i had it, i think this suggestion by Helton could be the go they are making me a T piece to suit so i'll give it a go and see, nothing to loose really i've tried every way possible so far except this way.

Here's the link to how Darren had his set up


Might be able to get something useful from that.

Hi Baz

Only way is to pick up the revs, maybe a small weight on the accerater or something to stick under the accelerater cable under the bonnet.I had the same prob with my diesel patrol, but it had the manual choke I sometimes have the bucket and run it trought twice as previously suggested
