Wacky Temperature Gauge Reply #15 – January 04, 2011, 07:37:16 PM I think the side of the radiator with the cap is the cool side heading back to the engine, so there should be a big difference in temperature between that and the intake. When you measured the temperature at the intake was the gauge reading higher than normal? Quote Selected

As the engine temp rises the coil allows silicone fluid to enter the clutch and when it fills the grooves in the clutch body and plate it engages the clutch. Would the outside temperature, being 30 as opposed to 70 prevent this from happening?Quote from: Blackbird1;348386I think the side of the radiator with the cap is the cool side heading back to the engine, so there should be a big difference in temperature between that and the intake. When you measured the temperature at the intake was the gauge reading higher than normal? Yes, the temperature gauge was in the green, but just before where it hits the red mark. I understand there would be a slight difference, but what I'm trying to conclude is that if the gauge was accurate, that antifreeze should be well over 130, otherwise the constantly mixing/moving coolant would be much higher, right? I mean where it is on the gauge, the antifreeze should be almost boiling. Quote Selected
Wacky Temperature Gauge Reply #17 – January 04, 2011, 09:48:14 PM Honestly, I don't think so, because your engine temps would kind of almost cancel out the outside temperature with the hood closed, kind of like turning a heater a house. If the fluid is leaking out of the fan clutch that is a good sign of it maybe not working. Quote Selected
Wacky Temperature Gauge Reply #18 – January 04, 2011, 09:50:29 PM I don't notice any fluid leaking out of it. I looked for that, thought maybe it would be wet, or something. Again, this problem only happens when the outside temperature is low, in the 30'sish and down. Quote Selected
Wacky Temperature Gauge Reply #19 – January 04, 2011, 09:53:30 PM When you raise the pressure of a liquid it raises the boiling point also , I would suggest trying an aftermarket gauge for at least a little while Quote Selected

Ive got a aftermarket gauge you can have in worcester its a high quality Fisher auto parts temp gauge Quote Selected

Wacky Temperature Gauge Reply #23 – January 10, 2011, 01:28:00 PM Hopefully picking up the gauge today, and we can go from there.I just understand why during winter the gauge says the car is running really hot, but on a 90 degree day, or a 70 degree day the gauge stays within middle to 3/4 of the green area. It baffles me. What sensors, etc could be affected by the cold? I guess I can try a new fan clutch, it's original as it is stamped ford. Quote Selected
Wacky Temperature Gauge Reply #24 – January 10, 2011, 04:26:21 PM When this happened on my 85 Cougar 3.8 it turned out that the temp gage had it's own voltage regulator. The Ford dealer changed it and all was well. Quote Selected
Wacky Temperature Gauge Reply #25 – January 10, 2011, 04:39:30 PM Did temperature affect it at all? Do you have any idea where the voltage reg is? You have the gauge shown here: http://www.coolcats.net/tech/general/8588base.html Quote Selected
Wacky Temperature Gauge Reply #26 – January 10, 2011, 05:52:52 PM That looks like the same base instrument cluster. I think the voltage regulator is on the back of the cluster. In my case the gage ran in the red when under load like climbing hills and up on the L of NORMAL pretty much all the time when the engine was warmed up. I changed the temp sender myself and that had no effect then I took it to the dealer and they replaced the regulator. I don't remember but it wasn't all that hot out. Quote Selected
Wacky Temperature Gauge Reply #27 – January 10, 2011, 07:43:29 PM Quote from: softtouch;265873When you say "turn the heat on" do you mean the blower?How about if you turn the blower on with out the heat on? does that make the temp gauge go up?Are the fuel and oil pressure gauges also affected?What I am building up to is a possible flakey IVR. Just out of curiosity, just for reference, if turning the blower motor on did make the temp gauge go up, does that mean the ivr is bad? I only ask because when i got home yesterday I turned the blower motor off, but left the heater setting to vent and the gauge moved a little. Maybe like the width of the needle. Barely enough to notice unless you were watching it. So I turned the blower motor to high, and it went up the same amount. Then I turned it to max ac(ac not connected) where the flapper in the HVAC system opens and the fan spins really really fast, and it went up a little more, just into the red. But the fuel gauge does not appear to move. Now although the width of the needle isn't nearly the amount the gauge seems to be off, maybe it is a starting point. I will install the temperature gauge tonight or tomorrow night and go from there. But it may be slighly off, due to an electrical problem. What might cause this? Quote Selected
Wacky Temperature Gauge Reply #28 – January 12, 2011, 01:56:11 AM short cut answer,,if the ivr is bad, you will loose fuel and temp readings 100%,, on the base electronic cluster.does your heater work on low or does it work on High only.? Quote Selected
Wacky Temperature Gauge Reply #29 – January 12, 2011, 08:56:19 AM The heater works on all settings. Maybe not on the low low one, but I think I did that. I think back in the day I clipped one of the coils on the variable resistor so that I could have the vent open, without the fan blowing. But it works normal on the other settings.So we can rule out the IVR, as this is only my temp gauge. Sitting in my driveway, level, after a thirty five minute drive home, I did the testing about, where the temp gauge would move. The gas gauge did not appear to move even slightly. Quote Selected
