Hi,
I have a -89 Ranger with 2.9 EFI and automatic transmission, it has about 100k miles on it. When I got it few months ago I noticed right away that the temp gauge goes almost over, and sometimes a little over, the 'NORM' range. I immediately replaced the thermostat and made sure that the cooling system is full and the radiator isn't full of dirt outside, still the same thing.
I've been driving it for three months like this now. I believe that it is bad temp sensor for the gauge, you know, the sensor with one wire going in it. Is there a known resistance for a good temp sensor? What are the ohms readings that tells me that it's bad for sure? Is the water pump known to go bad in these? I noticed that the coolant was dirty and old when I replaced the thermostat, that won't do any good for the water pump over time that's for sure.
Thank you!
