sensor is a 12m/1.5. Finished swap last nite. Runs like a top, smooth idle no surging or engine light on, no issues at all so far.Goes like stink compared to the 1.8, gonna put some k on it to see if it uses oil but the exhaust looks good so far.Are the heads, crank, intake, anything from the 1.8 of ...

tried any metric bolts that are near that size and no luck. its a straight thread as sensor seals with a gasket , tried mazda shops and parts stores but nobody seems to have info on thread size.

wondering if anyone can tell me the drill and tap size to thread coolant housing on left side of 2.5kl where rad cop sits. doing a 1.8 - 2.5 swap .
