Default temp gage fitting needed

Hey all I am wanting to use my mechanical autometer water temp gage. I pulled the plug on the head and believe it is metric M 12 or something? I dont want to disasemble this to drill this out and I am just leary about drilling into my perfectly good head anyway I have tried to find a fitting locally to no avail. Any thoughts...

99% sure autometer makes an adapter fitting for the LS1 heads. Do a search here and you'll find a part number I'm sure.

If you are trying to go from metric to an SAE threaded sending unit you might want to try Street & Performance as they have adapters from the 12m 1.5 hole in the head to 1/8", 1/4" and 3/8".

egauges.com has them. about $5. 12mm with 1/8"npt threaded hole. ask them to mail it to you. they will ship ups for $8 if you don't ask for mail. the mail costs .87

i bought the adaptor and temp sender. the sender was $14

hope this helps,

Made mine out of the passenger side plug by center drilling and running a 1/8 pipe thread tap through. Works great.

Default autometer adaptor requires short sender

Use the cylinderhead temperature sender with the autometer adapter. Screws right in to passenger side head.
