If your temperature gauge is always low

I know many other s10/blazer owners have a problem with the coolant gauge showing a low reading. Lately i did a bit or research and i found the cause of the problem.

My temperature gauge always had a reading of slightly over a quarter mark. This is low considering it should be near 210 degrees. After installing electic fans my tempeature gauge show a normal reading of around 200 degrees. I checked with a laser temperature meter which matched the reading of the gauge.

This brings me to believe that the gauge does function but the coolant is not able to reach its normal temperature because of the engine fan. Don't waste your money on a new dash or sender for the gauge as it might make no difference.

Re: If your temperature gauge is always low

Thanks for the info

my truck has never went more than 2 notches above the quarter mark but the heater is hot and have never had it throw a SES

Now i wont spend any more money trying to get the temp up just a tad

Does this sig follow the rules?
On one website this sig got deleted because a mod got mad at me when i pointed out one of his errors

You might have a faulty thermostat. The engine fan (a.k.a clutch fan) won't prevent it from reaching the temp it needs to go to -- unless the thermostat is stuck open, preventing the small internal engine coolant loop that allows it to warm up so quick.

Thermostats are known to stick eventually, and hopefully they stick open instead of shut, but it will cause exactly that. In the case that it does stick open, yep, the fans will make a difference.

Re: If your temperature gauge is always low

most factory gauges read lower then what the engine temp actually is, mostly for the customers sake. A person used to driving an older carbed car sees the car hit maybe 180. Newer vehicles with EFI can safely run at higher temps but most non gearheads don't know that. Most Ford vehicles don't even have numbers on their gauges. MY gauge will say 160 on the dash and the scantool says that the motor is 184 degrees but the computer gets it's input from a different sensor than the one on the dash.

Re: If your temperature gauge is always low

I changed the thermostat twice, last time 2 month ago. As soon as i switched to electric fans the temp gauge started reading about 200-210 traffic and 170 highway. Before electric fans it was always at 150 or so after the thermostat opened.

I've noticed that will all the engine not heating up posts that a lot of people seem to think that thermostats last forever. For less than $5 and maybe a half hour of work you can replace it and rule this out if the engine is not warming up. Mine got stuck open early last winter and on cold days the engine wouldn't warm up past maybe 60°C. It would get to operating temp fine on warmer days though, so I didn't notice at first.

My temperature gauge always hits 90°C (goes a little over on hot summer days), the rating of the thermostat.

Re: If your temperature gauge is always low

I went through 2 different 195 degree thermostat so i think we can safely rule that out.

Ya I didn't mean you specifically, just in general on the forum.

Although one of my friends went through two thermostats last year. He just bought the car and the thermostat was stuck open, so he put another in and it was stuck open. He returned that one and went to the dealer to get a good one.

As nater said the clutch fan shouldn't really have an effect on the engine warming up. Since no coolant is flowing through the radiator while the thermostat is closed. I find that funny when some e-fan manufacturers advertise faster warm up times. Once the engine warms up and the thermostat opens then it starts going through the rad. I could only see the clutch fan cooling too much if the clutch was bad and locked, but that would make a hell of a lot of noise.
