200*F for oil, or water, temps is just fine...no worries.
220*F for oil, or water temps is just fine....but getting up there.
Many choose temps in the 160-180 range and that is not ideal for many reasons...too cool.
But even 235*F is okay for one of these engines.
Not to hijack the thread, but I have read many conflicting opinions on the 160-180 topic. Lots of people say this is too cool, many others say it's fine and that they've never had an engine wear out prematurely for running temp in that range. My engine was running in the 210-215 range with a 180 stat in the first 100 miles (90-100f southern summer days), but I altered the grill for better airflow and now it sits happy in 178-182. When I was in the 215 range, it dieseled badly on shutdown.
Just curious what your thoughts are on the 160-180 being too cool.
I run a 160 thermostat and I set my fan to come on and off at around 170 for my set up that seems to work the best normal running temp is 180 no matter the weather for me if my car goes much over 200 even under the hottest days 35C to 40deg C then I know there is a problem with fans or water pump belt and It only gets to 200 on highway drives and I think that is because of my fan shroud set up is restricting airflow at speed but is amazing in traffic just goes up to 180 fans kick on and pull it back down to 165 170 and turn off or it will just hold it at 180 on a hot day.
I really need to try a no shroud set up I bet that would fix highway heat but it will make it worse in traffic.
As for Run On mine did that when it was fresh and tight too I though it was too much timing but it was not and went away as it loosened up. I broke my engine in driving up a mountain.
I think people confuse 160 thermostat with that is where my temp will run but that is not the case all it will do is allow the water to flow @160 your fans and rad still need to be able to control the heat. If your cooling set up can maintain 160deg f that is a super cooling set up. It is hot here all year round I would be lucky to see a few weeks a year of sub 10deg C mornings and average of 20deg c days other 49 weeks of the year is 30deg c to 40deg c day or night .
If I was in a cooler climate I would run a 180 thermostat. I think running at 200 210 is fine too but you have very little margin for error if anything happens you will be pushing water out before you can find a good place to park and let it cool down. Just got to find what works for your car and climate.
