k when its below zero the rotors ice up and it inject the anti freez to deice the rotors so when it starts rotor seals dont chip and crack and go boom! so hook em back up if ur gonna drive below zero

The sub-zero starting system has always been disabled on my car and I used it for a couple of years in winter, even at -30 degrees without any problems. Compressions are still very good and has over 120K miles. When you start the engine and stop it without warming it up well enough, even above zero you could get it flooded, the next time you start. This is because the water that is produced in combustion condensates in contact with the rotor filled with cold oil while warming up. If the engine is stopped before vaporizing all the water that is produced, it would then condensate on rotor surface and a layer of ice if below zero. So always make a complete warm up and you won't need that sub-zero system. I'm not sure about this but I think that even Mazda recommends to disable it. If your engine is flooded with coolant and get it to start after, the coolant that remain in seal grooves will vaporize and form sticky matter (like sirup) which will stick the seals, is that what you want?

i live in miami....coldest it gets is bout 50 for 2 days down here

lol

:thefinger:

Just try this. Start your rotary early in the morning and stop it after about 30 seconds. Come back half an hour later and start it again, you would notice that it is harder to get it running even in Miami.

hmm never noticed that...too bad i dont have my 2nd gen nomore...

I would be careful not to carbon lock the engine by not letting it warm up before shutting it off.

yuca de donde tu eres?

maybe in n pole
