Temp sender???

An automatic radiator switch with a relay circuit ,with twin pullers is what I have had forever.Never a problem,runs right at 190.I may hit 200 on the hottest days in traffic.

FYI. Standard equipment on a Superformance.

my fans come on at 90-92 degrees C .... shortly thereafter go off as fans have done their thing - unless in slow crawling traffic .

I have a manual switch that i use in the heavy stop/go traffic . seldom has it ever reached 100 C on the hottest days and by that time the fans are on and again, shortly therafter they go off .

as others have said , perhaps your gauge is not accurate - or perhaps mine either . LOL . Bill

Thanks for the thoughts. I think I'm going back to square one and start all over. I am running a restrictor plate, not a t-stat, will switch to a 180 degree t-stat. I am only running h20, will put in a mix (50/50 anti freeze/distilled water). The car only has @ 130 miles on it, was just runninng h20 to make sure there were no leaks. May add a bottle of Wet Water. Running a 16 lb r-cap, that should be OK.

I'm still not sure how to tell if temp switch is off, or if the gauge is that far off. If it can't resolve it, I will ask Olthoff, will be down there next week to pick up another car.

Sounds like I better pick-up a couple more Lucas switches to be ready
