car still diseling run on prob

a thermostat is designed to open at a certain temperature,holding the water in the radiator till the thermostat reaches that temperature..thus allowing the water to be cooled in the radiator.he may need a larger radiator but switching to a cooler thermostat will definately make the engine run hotter,I run a 195 in my duster 340 and 200 is the hottest I have ever seen it in the middle of the day idleing in traffic in the middle of orlando and it was like 90's that day and I don't run a shroud,it runs a constant 190 degrees unless parked in traffic,I run the autolite plugs in everything.

How could running a lower temp thermostat possibly make an engine run hotter??? That don't make any sense at all. Hold the water in the radiator to cool it?? So that means your keeping the water in the engine good and hot, right?? Then cool water finally hits the engine when that 195 degree thermostat opens and the temp spikes are all over the place. I run a 180 thermostat in my 360 and even with 4:10 gears it never gets over 185 degrees. That's with a stock radiator in the middle of August which can be 100 degrees here.

BTW: I worked for Hyster forklifts for 11 yrs. and one big problem we saw alot was keeping lifts cool in hot factories. We always found running a 180 thermostat helped at least some.
