Last time we played plumber, but we had one more thing to plumb. Big tires like this mean the power steering system is going to get hot so we opted to add a cooler. We only had enough space for a Hayden 401 cooler, which we got from Summit Racing. Since we were in the engine, and the LT1 already had the lines, we added another 401 to cool the engine oil as well. We hung both coolers off of a GenRight Off Road universal YJ cooler mount. It is basically the same kit we used in the last installment, cut for a YJ grille, but it ships raw. We had to weld the tabs on and paint it ourselves.
