Hey guys, hope you're doing well with how crazy its been around lately.
I have a question about thermostats but first a little background.
Skip if in a hurry!!!
I have a 1fz powered 100 series Land cruiser that when I first got had a little overheating issue wasn't really a big deal but at the time I didn't have enough time to fix the issue. So basically the car used to over heat just a little bit enough to get the ac to shut off as soon as I stop and it will return to normal within a minute of driving so to stall the issue I changed the thermostat from the regular 180f unit to a 170f thermostat from a 1hz I think it was that kept everything ok for a while until I had the time to overhaul the cooling system on the car so a fan clutch, radiator and coolant flush later (wp is still doing fine) the temp on the gauge dropped to what I think is way too low I will attach a pic but it sits at about half way of where it would normally sit this is as high as it gets while cruising at speed no matter how hot the ambient temp is however, while parked the temp will start to creep up mostly to where it should sit and on rare occasions a little high to where the ac will cut off.
Question:
Is this related to the thermostat staying wide open for most of the time.
Also the car is desmogged (it comes from factory with no egr or oxygen sensors) so is it fine to keep it as is or should I replace the thermostat with a 180f one.
If I had to change it I know there is a gasket that goes around the thermostat is there also a second gasket for the housing or do I use some sort of sealant around it?
Sorry for all these questions but this topic is way too confusing for me as where I live many people think cooler= better but I have a bad feeling about this assumption
