i Got an 89 civic ef with b18a1 block and b1 head.
I was wondering if i can put a 2 prong thermal fan sensor back of the block. like this picture



and just leave the one on the themostat not plugged. will it still work?
I have one on my d15 block
Dont feel like extending it to the thermostat.
Rather use the 2 prong one.

 

Where would you screw that thermo switch in on the back of the block?

 

I thought about doing that before too. If you tap the block so it can thread and make an appropriate hole I don't see why it wouldn't work. My experience is coming from the D-Series block though, the 92-95 1.6 block I was working with had the provision to mount it the "older" way but it wasn't tapped or drilled through. I ended up extending the wires though, I didn't feel like spending for a tap kit for a one time use.

 

isnt there a threaded hole already? Can anyone confirm
Its the two prong.
Mine was located on the thermostat.

 

 

o/p why not just extend the wires? takes a minute to do that

 

alright i thoght Bout it. just gonna extend foumd out i have to threar a hole.
like what 4dref posted.
thanks for the replies
Much appreciated

 

Yea either there is already a sensor back there, or it would be on the thermostat.
