I also have not been happy with the water temp the car runs. Other 5cyl cars I have had, my two previous Coupe GTs, a 4kq and even a Quantum GL5, all ran hot. They would run at nearly 3/4 on the temp gauge and the fan kicks on about one needle above the 3/4 mark. Maybe it is my domestic ownership but it was always my belief that they should run a little closer to half way on the gauge and the fan not run so damn much when in traffic. This 4000 has been no different on coolant temp so I decided to chase the issue.
I first tried drilling a couple of relief holes in the thermostat flange to allow some constant coolant flow but saw no change. I then found an alternate temperature thermostat through Autozone. Instead of 180F it is rated at 160F. The box was Duralast branded but the unit itself was stamped Motorad. I installed that and drove it for a couple of days. Partial success, it now ran cooler and near middle gauge on the open road but the temp would still rise to 3/4 and run the fan almost constantly in town and it hasn't even been that warm here. Further research took me to a "Warmer Climate" fan switch that was about 10F colder closure temp.
Finally, I have an Audi 5cyl 10V engine that runs at middle gauge and doesn't crest above 2/3 gauge. The fan seems to cycle much less than before. My theory is that since it is not allowed to run at such a hot temp it doesn't cascade to a tipping point in temperature and isn't as hard to get back down to a lower temp with the electric fan.
My next problem is concern about making it to Carlisle, health wise. My neck has been killing me and I am having pain and finger numbness on my right side/arm from a pinched nerve. I haven't slept for crap for 3 nights now and I am running on coffee and 5 hour energy... I am really concerned about the 5 hour drive to Carlisle. I see the chiropractor again tonight and hope for some significant improvement before tomorrow morning...
