I live in CA. and my car apperently wasn't one. The previous owner had an engine fire. which basically melted the area where the ABS would be. I'm not even sure if my car had ABS... well it doesn't now. and the coolant tank for the Sub-zero system is partially melted. here is my question. the coolant hose, which goes to the Intake Mani. can i just remove it? i figure it would be ok just to pull it. since there is a valve which only opens when the oil reaches a cold enough temp. and since it is only open during start up, and since i live in Southern Cali. would it be ok? thanks guys.

 

Sub Zero Start was recalled by mazda (that was the one I think) and it was basically said to be worthless and should be removed.

Just buy a blockoff plate for it and remove it completely, problem solved

 

What years had the sub-zero start system?

 

i have the sub zero system in my 87 GXL, my 89 GTU dosent have it if that helps.

 

I pulled it. I don't think I used a block off though....I can't rememeber

 

If you're going to do this, PLEASE use a block off plate.
boosted1205 found out the sub-zero valve on the lower intake manifold can LEAK and cause an intake vacuum leak, even though he has capped both vacuum ends.

Reted, whouldn't this also be the case if the line was hooked up but there was no coolant in the side tank? Useless piece of crap...

 

Whoa! whats all this blockoff plate business? Mine is sitting there not connected to anything, im gonna remove the take today. WHAt block off plate? where is ti supposed to connect to the engine? my hoses are just hanging down, you guys got me worried now.

 

CA models do not have the cold start assist. You must have an out of state model.

It would be illegal in CA to have the cold start assist. It must be removed.

 

how is it illegal?!

 

It was not allowed in CA due to the increase in emissions. Even on cars imported from out of state, it was supposed to be removed.

Mazda also did send out a TSB as well suggesting that it be removed from all 49 state vehicles.

 

Yes, that is true.
It does not leak from the fittings.
It leaks from the valve itself!

You can then sell it on e-bay as a wiper fluid res. everyone else does.
