Cooling issues??
« on: August 21, 2016, 06:11:33 pm »
So i have a 1993 mv and i have an aftermarket coolant gauge, most of the time the van would not run above 202-203 and the cooling fans would keep it there or lower. Now my van is running at 204-207 and seems to not cool down at higher speeds like before. Before at higher speeds it would remain at 195 now it sits at 206-207 and is very conserning to me. Anyone know what is happening, i played with the idle screw, to idle down to 800rpm from 1000 and im afraid it is running to rich and could be causing the engine to keep or create more heat. so i replaced the resistors on it and didnt change a thing, maybe my coolant switch is bad and isnt turning on the aux. pump?
