pic 1, its the stock water temp sending unit location
pic2, that is part of the cold start assist system if i remmember correctly and the hoses fo the the cold start bottle on the passenger side of th eengine bay. I have heard people disabling them some how.

 

So have I. Can I just block off the Cold Start Assist?

Question about blocking off the OMP. I got the plate and shizzle to do it. But the little thingy is sticking out like 4mm. How can I push that in so the block off plate will be flush with the front cover? Do I have to take the front cover off and remove that gear thing?

 

It's technically called the "sub zero assist" system, and Mazda recommends getting rid of it.
Yes, you may use a block-off plate on it.

Why the recommendation from Mazda?

 

Cause they thought it was stupid too?
I dunno...really.
There's a TSB (technical service bulletin) issued by Mazda to all it's dealers to throw that thing away.

LOL. Thank you for enlightening me. Was it merely a TSB or a proper recall?

 

No recall.
Just a TSB, which meant that this was voluntary for Mazda dealers.
Recalls made it mandatory.

Not COLD START. SUB-ZERO. Something rarely seen in real life in Texas.

It injects/injected a starting fluid when the sensor in the pan detected a temperature below 3.2 F or 16 C.

Its shown in the free, online, fsm.

 

what exactly is the fluid that it injected?

 

90 percent anti-freeze and 10 percent water. It's in the fsm.
