Hi all. Done a couple of thermo top C installs, the last one I did was to my Navara, which works well.
As half my heated screen is dead Ive decided to go for a fuel burning heater install, the thermo top C units are getting a bit long in the tooth now, and generally require an overhaul/decoke and gasket set, the Rover 75 ones also suffer component failure.
as a consequence, Ive decided to go with the Thermo Top V variant as fitted to the Disco 3 and later range rovers, these are available on ebay from £60- £90, with various part numbers, and exhaust configurations. Ive picked one up from a breakers on ebay, and asked them to leave the plugs on, with a length of wire tails.
the reason for this is whilst the wiring is on and stowed on the Disco 2, its stowed on one plug, and the thermo top V (and C for that matter ) has two sockets on it, one for power and one for the various control lines and fuel pump output.
my intention to control its switching, is firstly via the 12V signal supplied from the alternator via the ambient temp sensor when the engine is running and outside temp is less the 5 degrees . ( this may or may not be already fitted- to be investigated )
on the Navara I used a cheap Chinese RF plipper remote control with a latching output to provide a start signal, and Ill replicate this on the discovery.
I will produce a "how to " by way of contribution to this forum, but first a question.
Im assuming that some sort of provision has been made for the fuel pump to pick up fuel from the tank, as there is an in tank pump fitted. I have noticed on the top of the fuel pump assembly that there is a plastic blanked off nipple type thing, is it as simple as cutting the end off this, or do I need to tee into the low pressure pumped outlet from the tank ? or alternateively fit a separate pick up to the tank ?
