I accidentally got the wrong radiator from advanced auto parts, it all lines up with my transmission and coolant hoses. Unfortunately, the radiator has a hole on each side that doesn’t line up with anything on my truck. Do I need to plug them up? Will it shoot out transmission fluid or coolant? Any advice or ideas appreciated
Do these extra holes look a whole lot like your transmission lines? Those could be for the oil cooler circuit, which your truck may not have. If that’s the case, you’re fine to leave them open.
