Re: EF Running Temp
Can't agree about removing the 'stat. It's there for a purpose, several in fact. Obviously it's there to promote a quick warm up. The longer the engine is at lower tempertures the more fuel the ECU will pump into the engine because it thinks it's still cold, or warming up. Exit good fuel consumption!
It's also there to CONTROL coolant flow. The water pump can circulate coolant very fast, far in excess of what the engine should normally need. If the coolant circulates unchecked without a 'stat it won't collect sufficient heat from the hot parts of the engine as it is circulatuing through the system. And you run the risk of caviation which will aerate the coolant, further decreasing its efficiency.
It's true the rads do block up, especially since they are horizontal cross flows. The sand problem is well known. If the rad is clean inside, and everything else is on spec, there should be little need to depart from a normal 'stat. Remember that the ECU is programmed to deliver its best results at NORMAL engine temp, as set by a NORMAL 'stat.
