i just moved from texas to wi never had to deal with the cold so i dont know anything about the sub zero start what does it do and should i use it

 

It probably doesn't work. There was a service bulletin put out by Mazda years ago to have mechanics disable it.

Their should be a reservoir in the corner where the passenger side fender meets the firewall. You were supposed to put 90% antifreeze 10% water in there. Their is a small electric motor on there that pushes the fluid into the intake manifold when its cold, kinda like how your windshield washing fluid dispenser works.

 

It should work automatically anyway, if not - then don't worry (one less bit to go wrong!!)

 

mine has never worked and we have some brutal winters here in ohio by the lake. does anyone have a copy of that bulletin??
