I was wondering if anyone has played around with there air con thermostats to try and make there a/c just that tad bit colder? I have overhauled my complete a/c system on my 94 td42 gq wagon. It is working pretty good but it wouldn't hurt to be a bit cooler. It seems that the thermostat is cutting the compressor off just a bit too soon. And it looks like you cant adjust the thermostats in these, so i was wondering if anyone has tried fitting a colder thermostat? Or perhaps tried moving the original thermostat further away from the evaporator allowing it to cycle for a tad longer. I did do this once to a vs commodore i had with great results, i fitted a mechanical adjusting thermostat instead of the non-adjustable electronic one and i put the probe into the air vent behind the dash and then just adjusted it to the maximum without freezing the evaporator, it used to get so cold it would blow frost from the vent. So just got me thinking about trying to get my gq a tad colder. Any thoughts or suggestions would be appreciated. Thanks
