thermostat?

I was lucky...coasted right into a shop where the mech on duty drove me to a parts place, I bought the belt, he and I installed it. While out I put in 20 bucks worth of fuel in his car. After we got done installing belt, he said I didn't owe him ANYTHING as I put the gas in his car. I dropped anther 10 in his toolbox! He really had me between a rock and a hard place but wouldn't take advantage of it....I was a lucky son-of-a-gun.....
 
Thats how EVERY shop should be. I bet you'd go back too! Thats cool you tipped him too ;)
 
The gen 1 has a coolant sensor that goes straight to the temp gauge and one that goes to the ECU. The Gen 2 only has one that goes to the ECU. The gen 1 is way more accurate. If you're on the freeway the gauge will go lower every time and when stuck in traffic it will go up a bit. The gauge has never moved on my 98 except when I overheated because of a stuck thermostat.
 
Someone with a Gen2 needs to compare the temp gauge readings against actual engine temperatures with a pyrometer.
 
Exactly....just because it doesn't move, that doesn't make it a "dummy" guage. How fake would that be? Start your car, its already on half so you'd never know when its warm/hot/cold, lol.

So basically you're saying that because the signal has to go from the sensor, to the ECU and to the guage its not as accurate as the gen 1? The time factor is almost unmeasurable, or should I say "understandable" by the average person.

I will agree with you on one thing, Gen 2's have a "delay" on ALL the instrument guages. Rev your car up...the rpm guage keeps going up but the engine is audibly coming back down towards idle. There is a HUGE delay in that factor, but I think its intentional so the average driver doesn't think that the gas guage is f'd up because it moves up and down while turning, or that the car is about to overheat because the temp guage keeps moving up and down.

As far as accuracy goes, given the appropriate amount of time needed for the newer guages to "adjust" I HIGHLY doubt they are "dummy" compared to Gen 1's.

I have a temp gun....someone bring me a gen 2 and we'll figure this out.
 
I surmise the PCM translates the sensor reading in such a fashion that the major portion of the temperature range is translated to mid scale of the gauge. Sort of like grading on a curve. :wink2-green
 
So...170-195* would be translated into halfway on the guage, hense the reason it appears to "not move"?
 
Possibly even a wider range. It is not uncommon for 215* to be considered 'normal' on today's gauges.
 
EEEEEE.....I think on most cars the factory fan setting is 210*, so 215* probably isn't very good, lol, but then again you have the "high" speed fan setting should come on about 220*.
