Gotta Be Nuts
Thanks Neil, one question. I was sort of thinking that if I put the T near the heater box it would be outside of the thermostat. Obviously it works but how does it get by the thermostat? I have a separate circulation pump ready to go. Our furnace is mounted in one of the under body storage boxes. I need to drop that so I can drill the needed holes, plus I need to add an air intake vent for the furnace.Mine is spliced into the the flow and return to the heater box under the dashboard.
If I open the grill at the front then pipes are there right in front of you and easy to access and splice into.
From memory they are 18 mm steel tubes, I Tee'd into them at the bottom in the rubber section.
Obviously to pre heat the engine you need to introduce a pump into the circuit on the engine side
I added an extra pump on the heater circuit side too , so that I could pump hot water around the heating and calorifier without having to turn the heater on.
Eberspacher said if apply an additional power source the the existing pump it may feed unwanted power back to the control panel, so I kept it all separate
Its worked perfectly.
I have put a valve on all 4 ports on the heat Exchanger.
Thanks Jonathon, I think the ignition is sticking a bit and might have contributed to the problem. Not sure how to fix that one, guess I need to pull it apart and see. There is a local auto electric shop, plan is to swap in the new starter I have on order and have him look into rebuilding the old one to an HD spec. He is also looking into a quality replacement as a possible alternative. I plan to travel with a spare alternator and starter.Two issues with the starter. One is the bendix drive is not retracting the gear. That's a lube/wear issue. The other is a sticking/welded solenoid contact set. Both can probably be addressed by you on a bench. Both sound different, and typical a stuck bendix is will eventually retract on its own.
The final option is a sticking ignition switch, or sub relay if used. You would need to test with a meter when this happens to determine.
