Engine Cooling problem
1995 GMC Truck V8 Two Wheel Drive Automatic 189000 miles
I changed my radiator in my GMC Truck, 350 engines and afterwards the temperature will not get above 160 degrees. It is affecting my engine performance and gas mileage. I have changed my t-stat and temperature sensing unit and it still runs at 160 degrees. I made sure the t-stat was a 195 degree as well. When I replaced the radiator it appeared to be exactly the same. Everything fit perfect, the thickness, width etc. Was the same. Is it possible I got the wrong radiator?
Oh, I have also noticed problems with my transmission not wanting to shift since the cooling problem started and the engine idles up when this happens. After I stop the engine and wait a while, it runs normal. I may do this once every couple of weeks.
Any help would be greatly appreciated.
