Also I should add it was ready for a flush. The OEM coolant was somewhat dirty.

You are spot on here. I flushed a gallon and a half of coolant out of the radiator (about half of the system) and refilled with the peak. Did the old school method of burping (with my custom funnel!) heat on, got up to temp, revved, opened and closed tstat multiple times, restarted multiple...

For the record what Brand 180 tstats are you guys running? I assume OEM is only available in 203. Also what tuners are you using to reprogram fan speed and the like? Thanks!

Shouldn't the shutters be wide open at that temp? I see why people remove them now. May put that on the bucket list too. From what others say that have done the tstat is it def brings down temps across the board. I get that no matter what tstat is in there the system still has a hard limit on...

If I am off base here, then what is the root cause of towing a heavy trailer causing the engine to run hotter?

I think my oem thermostat is fine, but it is designed with daily driving in mind. Works fine under normal driving. Towing heavy keeps the RPMs up and in turn heats the coolant up much faster. The coolant temp is going to be hotter at certain engine spots than others, its not exactly the same...

These temps are at 60-65 mph with around 50* ambient, so plenty of cool air flowing into the radiator. Im not sure a fan is going to add anything at those speeds, but I could be wrong there. Seems like letting the coolant flow to the radiator earlier in the heat cycle / more often would help the...

The timing will increase volume. More circulation thru radiator per hour. Obviously this works as reported by others who have done the mod. This weekend did 500 miles. 250 towing 6k, 250 unloaded. Just got back from towing 6k 125 miles. Unloaded max temp 209. Loaded up max temp 222. Was 48*...

Thanks for all the info guys, im going to start with a flush and a new oem stat and go from there. Maybe grab a 190 tstat and be the test dummy..

Flow is the same pressure when open yes, but flow volume is increased due to the Tstat opening earlier in the heat cycle. So it will bring temps down when driving due to the air flow. Sitting in traffic with the fan on, yes it wont be any different than the OEM.

This is not true. When they are closed they flow very little and keep the coolant in the block via bypass ports. If they always flowed the same there would be no point to it. Tstats open when they reach a certain temp and allow the full flow to the radiator. Thats why lower tstats circulate the...

I do not think its an efficiency problem because it runs 200-210 when not towing. While towing a 6k camper, into the wind no less, i was in either 5th or 6th gear most of the time at 60-65mph. This is 2000-2800 rpms for extended times which just does not happen when not towing a heavy load...

Ok, well that was a productive conversation. Im thinking about putting a 190 thermostat in mine. (Maybe 180 but that seems to ruffle some feathers) Hitting over 220 when towing 6k camper in 50* ambient. Would not mind running a bit cooler than that. But, but the computer will add more fuel...

Did you check the coolant reservoir level? Sounds like possibly a water pump.

Replaced the spark plugs. All 16 with new NGK. I was surprised NGK is what came out factory. I was expecting mopar. 82k and 3500 hours. They were showing some definite signs of degradation and wear.
