After making the necessary cuts, we mocked up the radiator and condenser. We removed an inch of material from the passenger side of the radiator support to make room for the lines and fittings. Vintage Air provides detailed instructions, so we marked the area with tape and used a cut-off wheel to make precise cuts. With the compressor mounted, we can move forward to the condenser. In our case the “510” indicates a 51-inch belt. Parts stores offer belts in 1/2 inch increments, and the last three digits of the part number typically spell out the measurement. After grabbing a few belts from the parts store to see which one offered the best fitment, we settled in on a 15510 V-belt. Now the alternator can be installed on the Steel-eez bracket, using the supplied bolts, nuts, and washers, as well as a spacer for proper belt alignment. We rotate the compressor so the hoses can be routed up and over the top of the engine. As part of the Vintage Air SureFit kit (PN 961166), this Sanden SD5H14 A/C compressor offers a double V-belt pulley and a wide range of mounting configurations. The two engine block boltholes are the same ones that were used in the original alternator bracket. The Steel-eez bracket is designed to bolt directly into place, using existing boltholes in the engine block, cylinder head, and water pump. The bracket comes in raw steel, so we sanded it and painted it silver. The Vintage Air Steel-eez bracket (PN 146037) features a heavy-duty steel construction with a wide range of adjustment for the alternator and A/C compressor. We also noticed that the wiring terminal interfered with the bracket, so we bent it over at a 90-degree angle. After mocking up the bracket, we realized that this temperature sender needed to be installed first. Now we’re ready to go back together with the new bracket. We blasted on a couple of coats and then freshened up the exhaust manifold with Calyx dressing. Chevrolet Orange will wake up any old engine. Even though this is a low-mileage survivor, 55 years of grease has accumulated beneath the alternator so we degreased the engine and surrounding areas in preparation for some fresh paint. We continue stripping down the engine by removing the original alternator brackets. In order to prepare the engine for the new brackets we must first remove the alternator. Originally, the alternator was mounted low but the Vintage Air kit relocates the alternator with a special combination bracket.

We also begin disassembling the interior components in preparation for the new Vintage Air evaporator. In this article, we’ll cover the Steel-eez brackets, condenser, hard lines, and drier installation. Since this installation involves quite a bit of shop time, we split this into two parts.
66 NOVA STOCK MOTOR INSTALL
To install this kit on your Chevy II, you’ll need an assortment of hand tools as well as a cut-off wheel and a step drill bit (or a 1-1/4-inch hole saw bit). The car has already been upgraded to an aluminum radiator, which will benefit the cooling capabilities of the six-cylinder engine. The first step is to drain the cooling system and remove the radiator. The final item on our order was an E-Z Clip hose system (PN 547002), which means that we can easily build our own refrigerant hoses and crimp them in our own shop. We also added Vintage Air’s new Control Panel (PN 473272), which fits in the factory location and makes it completely electronic. It also fits 230- and 250ci Chevy inline-six engines. We ordered a Vintage Air SureFit kit (PN 961166), which fits ’66 and ’67 Chevy II/Novas and added the Steel-eez compressor bracket (PN 146037) for direct fitment on the inline six-cylinder. As it turns out, Vintage Air makes an exact bracket for the engine, which made for an easy decision.
Our original question was in regard to the engine and how we would adapt a Vintage Air kit to the inline-six. This is not the most likely subject for an air conditioning install but Vintage Air makes a kit for it and we’re willing to take on the challenge. Our starting point is a stock ’66 Chevy II with its original 194ci inline six-cylinder engine.
