Hey guys, I have a 99 LS1 and it is going into a 69 Camaro. I have an Autometer mechanical water temp guage with what I think is a 1/4" pipe fitting.....not sure on that size.....regardless, is there a place on the head I can use? Or is there another place I can use?

Thanks guys,

Joe

 

drill and tap a spot on the water pump for it.

 

JPH...thanks, I was kinda thinking the same thing, but I was curious, is it possible to drill out the unused port in the head on the pass side to accomodate what I need? (I am looking for cleanliness here) I'd much rather have it on the head if possible, but if it any of you guys feel I better not drill and tap on the head, I guess I better go for the WP.

Any thoughts?

Thanks,

Joe

 

I and many have used the passenger head, just remove the plug and either find a 12mm sender, Use a 12mm to NPT adapter or drill and tap it for NPT. I drilled and tapped mine for 1/4" NPT.

Many think that it read hotter in this location. It might, but not by much. My thinking is that I would like to know the hottest spot in the engine anyway.

 

I drilled out the passenger head for my stock gauge. It works good.

 

Very cool guys. Thats the awnser I was looking for. I think I'm going the route I originally thought, but now that means I need to modify my Pacesetter headders. They are about an 1/8" away from the headder flange thats bolted to the head. Seem like an easy mod.

THANKS AGAIN GUYS!!!

Joe

 

yes you can drill that out.(be super carefull) It will give you a better reading also.
