Would anyone know the Part Number for a 160 degree thermostat for my 74 225???
I would recommend you don't use one. A 180 is a much better one to use. A 160 won't allow the engine to get to full operating temperature. This causes poorer fuel economy, sludge buildup, accelerated engine wear, and a worthless heater. If you have a cooling system problem, find out what it is and not just put a bandaid on it.
but a cooler engine produces more power.
I wouldn't install a 160 in mine. The 160 doesn't let the coolant stay in the block long enough to absorb the heat. Long story but I have tried all three 160,180, and 195 and the 195 worked better than any of them on the keeping the temps down. I know....... its hard to believe. It ran better also in normal day driving.
A 160° thermostat is a poor choice unless your goal is to reduce fuel economy and increase oil contamination and resultant engine wear. If that's what you're trying to do, by all means use a 160°*thermostat
well I can see what points you guys are making, and im sure their valid, but this souther texas head is hard as hell on these older rides that havn't been rebuilt and flushed during a rebuild. I've used 160 thermostats on damn near hot rod project ive had down here, and usually operating temp stay right about 185-190, and im quite comfortable with that.
I guess I learn something late at night and will be ordering the right thermostat to keep my engine nice and cool. I hope i didn't read the info wrong
195 - great thermostat, keep coolant in the radiator longer so it can cool down
180 - also an excellent thermostat
160 - bad thermostat, coolant doesn't stay in radiator long enough to cool, fuel consumption
805moparkid: does the thermostat choice depends on the size of radiator as well?
Thanks
