Thank you all for your help. I have been doing a fair amount of reading from various posts on the topic of CRD engine cooling systems, and I am starting to get a good idea of why I am having a few extra running problems in the winter. However, I still need some clarity on some of the lingo you fellows use and some of the topics discussed as I am rather ignorant on this subject - sorry for this.
What the H - E - DOUBLE HOCKEY STICKS do you guys mean by the following...
1) HOAT?
2) IMHO?
3) Viscous heater?
4) Broken FCV? -- (For you, dirtmover).
5) ECU, (Engine Computer Unit)?
It seems to me that a lot of LOST members like the thermostat in the hose trick. If I try this, I will probably use the hottest, (195 degree?) thermostat available, as I live North of virtually all of you. -30 degree Celsius weather is quite common up here. Has anyone finally tried using the thermostat that, if it fails, will fail in the open position? Has the member had great results with using the "fail-safe" thermostat?
I am also not clear on the consequences of the OEM thermostat failing with respect to it's effect on the coolant bypass system, and what the bypass system is for, any way?
I am willing to spend good money on a reliable, permanent solution to the OEM thermostat that would not clutter up an already busy engine bay. Is the rebuild performed by Kap, (Mark Kapalczynski, I am assuming), a complete replacement for the OEM thermostat, or simply another add-on to the OEM like the t-stat in the hose trick? If Kap's rebuild IS a replacement for the OEM t-stat, does the coolant bypass still work, or does it even need to work?
If the idea of the coolant bypass system is to warm up the engine more quickly, (evenly?), I would say that it is not working well up here in Canada. I keep hoping someone like Keith at GDE can reprogram the computer to idle up the engine to about 1500 RPM about 1 minute after starting to hasten the warm-up time.
Papaindigo: Thank you for the VM USA contact information... it may not do me any good to consult them, but I won't know for sure unless I try. I WILL DEFINITELY try George at VM Specialist UK thanks to the recommendations by Glend and others.
Keith at GDE: I promised you I would purchase at least 2 tunes and a couple of turbochargers from you... I have not forgotten, my promise has simply been delayed. My career experiment in Fox Creek, Alberta has gone sideways, and I am back in Edmonton looking for work to advance my career. I now know that you have injectors as well; thanks for telling me, (any chance, by the way, that the more advanced piezo-electric injectors mentioned on VM Motori's website incorporated in later edition engines will work in the Liberty CRD engines, and will they provide more performance and efficiency?).
