Righto.
Re: radiator cap. I haven’t been told that the radiator cap has been replaced and I haven’t done it. I will try that.
Re: my heater/fan solutions. You could be right that the thermostat and fans are doing it, but I’ve been playing around with this for about 600 miles and turning off and on the heater/fan and it always takes the gauge down.
Re: the thermostat … could be right.
Re: the fans – you’re right – still not verified.
Re: the outside temperature. Yes – it may be less and less relevant, but one thing is true to date. If it’s a cold day, it happens; if it’s a warm day, it doesn’t.
Re: Your test. I will do that.
Thanks!
