ECT and EOT gauge ?s

Couple questions here..... First I was wanting to get these two gauges to add to my collection and was wondering what the max temp should be for the gauges..... Like for example should they both go from 100 to 250 degrees or is 180 max enough or what?

Second I've got isspro gauges already and there ev1 I think... Mechanical anyway not electrical and I can't seem to find any of those style gauges for the ect and eot. Do they make em? I'll change to auto meter just for these gauges but I notice I can't find a ect gauge that goes over 180 degrees. Thanks guys for any input!

Thanks

Shawn

They both need to be 250 *F gauges.

That's what I figured but I wanted to be sure. Thanks Mark!

Now just to find some that match.

I'm seeing 190'F ECT and 198'F Diesel EOT from my Edge Insight.

Shawn, it looks like the question is answered. But yeah, I know when mine was hooked up to a computer while I was towing, my ECT hit 240, that is where my clutch fan would kick in. So at a minimum 250 degree gauges.

In my opinion, you don't want mechanical gauges when you are talking about having hot liquid running thru the cab of the vehicle. I wouldn't do that, but then again I'm a wuss.

I know the antique beige gauges by autometer go to 250, it's short sweep, but it does the job. EOT I use thru the DashDAQ and that's whatever I want it to be.

hey tex, wouldn't there be something between the sender unit and the gauge so that you would not have to bring the hot fluid in to the truck, like with a fuel psi gauge?

Only with an electrical gauge. Mechanical gauges put the oil or water or whatever directly to the gauge.

Yep. In all honesty, the electrical gauges aren't as bad as lot of people say that they are as far as accuracy goes. Only time I notice any fluctuations is the first time startup on a cold morning, but after it's warmed up there isn't much issue. I have all electrical gauges in mine, I just don't want any hot "stuff" coming in be it fluid or air.

Just to note, the placement of the sensors for the temps will effect the readings.

You can, but should never bring any engine fluids into the cab for gauges.. You always want an isolator similar to this.. They have their own set of problems, and when you add up the costs, electrical gauges/senders are much more attractive for daily driven vehicles..

On edit: how do you get even close to accurate temperature readings from a mechanical gauge that is a dead end?

The biggest detriment to electrical gauges is a bad ground. I had to bring an engine ground into my mustang to get consistant temp. readings. The body ground was not good enough.

Mechanical temp guages use a thermocouple, there's no fluid going to the guage.
