asv, sap, szs the block off plates have these abbrev.

 

why are you not asking the company who makes the block off plates???

Those are not normal FC abbreviations

 

The SZS one is sub-zero start.

 

which shouldn't be on the car in the first place

 

no it shouldnt!! im glad they made BOP for these finally!!
antifreeze injection??? what were they thinkin?

 

Mazda calls it a "sub-zero assist"?

has it ever worked or did it come from the factory disfunctonal?

 

i thought that was it but then what is the sap and asv

 

SAP = "split air pipe"?
ASV = "air solenoid valve"?

The block off people call it Sub-zero start assist.

I figured thats what the ASV means...but it should be called ACV, as its not exactly a solenoid...

 

asv is "air supply valve" as per the Manual

SZS is "sub zero start" As best as that sucker could be described

 

wow

all the bash on the sub-zero assist

may i ask if those who bashed ever used it?

 

it was on my car....
although i couldnt never tell when it worked or didnt .... i KNOW in fact it did because when i owned the 7 before i would come on here the owner told me to keep it full..every now and again i would have to refill it....i couldnt tell when exactly it was "injecting antifreeze" now that its out thier is absolutely no difference from when it was installed and functional....

 

well it was never on any California spec cars, and Mazda went and sent out a TSB saying to remove it on the 49 state models when the car came in for service.

 

For the record, Mazda calls it the Sub-Zero Start Assist system, and it was only fitted to US FC's (except California).

All the other countries the FC was sold in use metric measurements, so it would have to have been called the Sub-Minus-Sixteen Start Assist system.
