Between Omaha and Des Moines, 7 miles South of I80 | Thanks Bern I kinda forgot about fan clutch switch, seeing how some trucks used Engine's ECM(for fan operation) but some still used their own coolant switch(like Horton), to operate fan circuit. About radiator shutters; Are you showing your age? LOL And I didn't even know about a Torque convertor clutch coolant switch (thanks for the info) |
