ok this is a b17 bottom end with a b16a2 head. on my b16 block this freeze plug in the picture is soldbut this one on the b17 has thread though it any ideas wat is supposed to go ther?


and this is a pic of a sensor that i have no idea wat it is or were it goes can someone help me please

mtownsi

oh and the sensor at the top of the first pic is the knoco sensor right? i broke it but my ecu doesnt run a knock sensor so i can leave it disconected right?

pdiggitydogg

Yes, thats a broken knock sensor.
The plug is just that - a plug. Seal it up with a bolt and some rtv sealant. (or just get a replace the whole big plug from a junkyard piece)
Last thing looks like a coolant sensor for the head

mtownsi

can i just take the plug from my 1.6 block and put it in there wit some sealant

pdiggitydogg

yep

mtownsi

ok how do u get the plug out? and u were correct that sensor was to the head

youre going to have to get some kind of wrench or big socket on that plug
youre lucky its the hex one, and not a smooth wall
