Hi Guys - I need some advice on few issues around water cooling, oil cooling and heater stuff.
So the 2.0 TD engine is a conversion in a 1958 Land Rover so things are not to any normal standard arrangement. I'll break the questions up into different bits to try and make it clear but some are connected.
Firstly I have been worried that there's a problem with thermostats because the electric fan never kicks in. What I don't know is maybe the engine never gets up to temperature to need the fan, but I've had it stood on fast idle for ages and the temperature gauge is showing high (but I don't know if it's accurate) The fan works as I've bridged the terminals. The fan thermo/switch is mounted in line on the top hose to the radiator and I've taken it out and tested it - it switches at about 86 deg. So then I though maybe the thermostat wasn't opening so I also checked that and again opens at around 86-88 deg, no problem. I did also wonder if there was an air lock as the thermostat does not have the jiggle valve, I've since drilled a little hole in thermostat. I'm bothered that the engine is running hot but I just don't know it, but why does the fan never start - is this normal for these engines, do they run below 88 unless you are really thrashing them? The temperature gauge is an old smiths and seems to work OK but I don't know if it's accurate. I fitted a 10V stabilizer to it but not sure if that is needed or if that would make it read high.
Second thing is the oil cooler setup. There are two oil pipes feed into a metal tube (cooler) mounted on the water pump and these pipes and the tube get hot. The water coolant pipes which connect either end of this metal tube don't get hot, seems to be no water circulation going through. The left side of the cooler is connected via a hose that tees into the bottom radiator hose. The right side of the cooler connects via a hose to directly under the thermostat housing. Do these hose connection sound right and if so why no coolant circulation through the cooler?
Third thing is how to connect a heater matrix. I have fitted an old original LR Smiths heater but need to connect into the water system. On the Montego/Maestro setups where/how do you connect up for the heater? I was thinking the best method would be to connect into the oil cooler hose as this is similar size hose but the problem is that one it doesn't circulate as above and if I fit a shut off valve for the heater the oil cooler would also be closed off.
Hope this makes sense and you can advise.
Cheers
Martin
