Went back to the x fan (stock) and had the waterpump out . saw no defects so put it back. it has a thermo, so the washer probably wouldnt get me any thing. i have tried the gutted thermo also but still is hot. gona try to find the size (dia) of the stock w/p pulley . maybe its running slow. engine new ? i have had this truck for 10 years. but found a tag once that it was rebuilt by a marine eng co in michigan. bored it .40 over. but the tag looked like it has been there awile. i think rad shroud will be next project. has anyone fabed up one or just but it?
