i had this Duncan, I took me ignition leads out just to be safe side as my glanza is stored over winter..
to actually stop them, traps and bait, maybe look into poison as well
I had to do this for my Omex..
I fitted mine to crank pulley, and then had it balanced..
hope that helps matey..
as for sensor, I welded a bracket onto my sump..
again hope helps you with your build dude..
mines coming off road some point in November, and it be in hibernation..
altho am looking into cams, and building a race spec head and head stud conversion whilst off road.
also whilst on this topic, I found the cruise bonnet to be a very useful cooling tool, as air passes through radiator, it has an escape route..
this helps to stop heat build up as well..
and with cooling its more of a release of heat, think of it as a saucepan boiling water, lid on water...
don't forget about core efficiency either..
I have just done a lot of work to my glanza around cooling..
just did a 35min session round brands, and my temps were fine 92c and didn't rise at all..
now the problem with a civic rad, is is sits not quite in centre of car, so about 15 to 20 per cent...
