:meh:Hi, i've manifactured this heat exchanger for my cruiser , i still have to tig weld all together and then i need to instal it and make a bypass in the coolant hoses of my heater system , but i am not quite sure were the hoses are located. Can anyone show me by picture between wich hoses i best install this, i think i need two hoses cut on my 75 series. Here some pictures,thanks

On the LH side of the engine there is a coolant outlet pipe (above the oil filter somewhere)with a rubber hose attached that goes that goes into the firewall for the heater.
I would cut that and get the coolant to flow through the heat exchange and back into the cars heater system.
You would only have to cut one hose this way.

If you cut both heater hoses,the hot coolant would probably take the easiest route and bypass the cars interior heater.
The hose on the other side is returning the coolant back to the engine after it has been through the heater.
 
that's what i tought to , because your right about the easiest way, do you know why helton heat exchangers uses two hoses, my first thought was putting the exchanger in one line? Is this the hose?

What do you mean by two hoses? Its really one ,it just in one end and out the other.
Did you watch their instruction video.

Thats the hose I was suggesting,you will have to turn on the car heater to get the coolant flowing.

I got one of these,works quite well

thats nice work.

will that not really slow the flow of coolant to whereever you tap it from?

Some landcruisers have a rear heater where the coolant has to flow to the floor under the front passengers seat,I cant see this being any more restrictive than that.
 
I used a marine oil cooler and directed the rear heater hoses through the oil cooler.

With a 5 gallon water supply (taken from a stream or lake) sitting on my winch mount I pump the water through the oil cooler with a simple water pump. Do not use too big of a pump - it will reduce the residence time of the inflow water through the heat exchanger.

12 Volt Marine Utility Water Pump

Depending upon the ambient water inflow water temperature, I recycle the water a few minutes to bring it up to shower
temperature. I use about 2.5 gallon (10 liters) per shower.

I also pack a shower enclosure. It fold up flat - taking up little storage space.

Hope this helps ....
 
great stuff, rear heater hose is also an option , Rosco with the heater on to use heat exchanger ,can you control the temperature than?

Im not sure.It might be easier to control the heat by having a flow control on your cold water.
There will be lots of variables such as engine coolant temp,cold water temp and how fast the engine is idling.
 
A friend of mine had a large stainless steel tank fitted to his troopy and used the heat from the exchanger to heat the water in the tank.
He had a pump attached to the tank and used it for hot showers at the end of the day.
He said it also help keep his engine cool when he was in the desert in 4wd low range for long periods.
 
that's also a great idea,works like a boiler then and as he said he has kind of a second radiator, my idea was when arriving somewhere first thing shower, i got 3.7m of 8mm cupper tubing in the exchanger and hope it will warm up the water, i've got a tank in the car with external shower outlet( the white box on the side)

this pump is for the onboard water system, the shower hose is going from the tank to the heat exchanger( it's a 100L tank), in the back i have a doulton water purifier so i can drink even contaminated water if possible in case of emergency,but learning from my travels around the world i always take enough botelled water,so the tank is only for shower and water for boiling

Do you have any pics of the rear interior? Does it have a fridge?

Ive just ripped all the POs bed and sliders out and Im about to start refurbishing it.
I planned on using aluminium box section and angles to build the bed/platform.
1st Ill give it a good clean out to get rid of the red dust then I want to put some nice carpet on the floor with soundproofing/underlay .
