Outer Limits 4x4 Board

In the latest Fourwheeler there was a rundown of some of the cool new stuff available at SEMA. One that won best new product was the Thermo Cap


Basically a thermometer in the radiator cap. I reckon it's not a bad idea as my temp gauge in the Suzuki is, shal we say, less than accurate at the best of times and the rest of times it doesn't work at all. They come from Blue River Enterprises. Any one know anymore about them. I've tried Googling etc and haven't been able to find much info at all

Why whoud you buy one of these
and not just buy a new gauge set up

Maybe he wants to pull over to the side of the road, lift the bonnet to check the temp

If they were cheap enough they might be good, just so you can confirm that your gauge is working ok.

the real olden day cars had these factory. they were disguised as hood ornaments though.

If they were cheap, why would you assume they would be any more acurate than the standard nippon denso gauge in the zook?
Peter.

I assume the idea of them is to tell you the temperature of the water so that you don't open the cap and get a face full of boilling water and steam?

They would not give a very accurate indication of engine temp.

Why not just buy an infra-red thermometer instead???

Seeing as a typical water outlet feeds to the top of the radiator, and this is where most aftermarket temp switches are located. They could help to set up your thermo switch temperature..... Thats all

Bingo, not as a primary guage but so you can see what is happening before you open the cap. As to why not buy an infra red thermometer, because these are less than $30USD
