Hi guys,
Have a mate with a 4.2GQ with a twine shower. Has been installed for some time now and no matter what he drives like, the output water is not hot or even warm.
He has had it back at a few dealers (OOT I think was one if them) and everyone is scratching their head.
I have had a quick look and the shower is in the same place I would put it so we are all up in arms.
Does anyone have any photos of their shower installed in their 4.2 GQ that you could send to me?
Thanks
Tim

A couple of questions.

Did the unit ever work satisfactory?
If yes what has been repaired replaced in the cooling system lf something has been done did it require the coolant level drop. If yes, has the heat exchanger had the air bleed out.

Is the Water Temp gauge holding the same Temp as always?

Unit has never worked properly, could maybe be an airlock, that would be one to look at and the temp gauge stays in the normal range, doesn't move up or down one it reaches the normal height. The heater in the vehicle works fine still also.

Tim,

More than likley the unit needs to be bleed. I am not sure of where the inlet and outlet pipes are on the Patrol but you will need to disconect the outlet from the exchanger (to the vehicles heater) run the engine at approx 1000RPM and as soon as water flows from the exchanger, stop engine and reconect the hose.

Hopefully hot water should be delivered to the shower head||||

JD,,,, I think if the guy has been driving the vehicle around and getting to 3000 to 4000 revs it should have cleared most of the air, it still should be working to some degree even if there is some air still in the unit. I could be wrong... Michael.

Michael,

But where will the air go. It can't disapear. If the HEU is above the radiator header tank, unless the air is forced out it will remain in the HEU. Normal engine cooling will remain to run OK.

Hi Tim, may sound like a silly question but has your mate tried it at revs above idle? It really should get at least warm at idle and better at more revs,,,, Is the initial burst of shower water very hot and then go cold??

Tim, you don't actually say where he has it in the water circulation system. I presume it is in series with the heater. If it is, can you tell us if the heater works please. The heater slide should control the amont of water flowing through the heat exchanger. Some owners need to cool the heater down to get it right from the top temperature. Ours can be too hot for instance if the engine has been running long. GU though, but the engine does not differ that much.
Cheers,
Who?
John
