yes but it is running to hot when the fan kicks in. would like to have it turn on earlier
My son in laws Duramax truck was running hot. Turns out, all the heat exchangers (radiator, a/c condensor, charge air cooler, tranny and engine oil coolers) were plugged with dirt and debris. A morning with the air hose and water hose cleaned it up and no more overheating.
