The same car as Heat Problems Post.. but this only happens around town

the volts meter sits on 15volts until the car warmup and after the first time the thermo fans kick in and then turn off the volts drop to around 14.1 volts and the temp sits high but I can drive 100km around town and this willn't happen unless I lest the car idle an then it starts doing this but once it has started no matter how much driving you do it will not come back down and sit on the N it sits on the start of the R ( I Have an 82 thermostat in it)


any ideas

Thanks

Ea Fan

Thermostats do'nt always open at the right temp. even when new. I almost cooked a new engine that I built because a new thermostat did'nt open at all. The "normal" range is there for a reason. As disconcerting as it is to have the temp. up to 3/4 on the gauge, this is how Ford designed the car. The gauges are very touchy....

yes the gauges are very touchy but why would my volts drop when the car gets hotter

The belt's nice and tight? Heat = expansion and if the belt's a little loose this can happen. No other ideas on the volt drop though

Heat causes voltage drop, but it really should not be noticeable on your gauge. If your battery is getting a bit old, the alternator can charge higher than normal for a while after being started. If you can get hold of a good multimeter, test the voltage at the alternator and the battery from start up till warmed right up and see what you get. Do'nt always beleive the gauge.

I don’t quite understand what you mean?
Anywhere from ‘N’ to ‘R’ on the temp gauge is ok. You don’t want the engine staying too cold.
14.1 volts is ok for a normal running voltage. The regulator can cut back after initially charging the battery.
You say this only happens around town..
What happens out of town?
I’d expect with an 82° thermostat the engine temp reading on the gauge would drop due to higher airflow at highway speeds.
What daytime temps do you normally get in Townsville?

On the highway it stays alot cooler and the volts don't drop like they do in town.. temp around here is about 32
