28 THE SHOP AUGUST 2017 When a radiator arrives at Glen-ray, it's unboxed and Schirmer assesses what it needs. Customers are offered a choice of rebuilding their core or re-coring it with a new unit. Schirmer checks the date code and calls the customer to discuss the best way to proceed based on use of the car. When restoring a radiator, Glen-ray com- pletely disassembles the sent-in unit and immerses all parts in a boiling tank filled with caustic soda for approximately 30 min- utes. Then the components are pressure- washed and dried. The glass beading of all parts comes next, followed by straightening and priming the side brackets. If there's a transmission oil cooler, it is also rebuilt. All fittings are straightened and so are the top and bottom tanks. The top tank usually needs the most attention. Glen-ray removes any dents. Schirmer fabricated some special dollies to hold and de-dent the top tank as much as possible. He admits that some tanks will turn out better than others, depending on the severity of damage. The radiator core is rodded out with a thin piece of steel being slid down each tube to clear any debris. All tubes are re-soldered into the header plate (this is what the tank solders to). The radiator is then reassembled and tested. When it tests out OK, it goes into the boiling tank for 30 seconds to neutralize any still-active fluxes or acids. It is then dried and the band is filed with a tool that removes excess solder from the tanks or topside brackets (where they are soldered to the tank). Priming and painting comes next. Glen-ray uses a paint that is chemically hardened and strives for an almost perfect match to the factory finish. Re-coring a radiator follows basically the same system, except for the process involved in rebuilding the radiator core. Any radiator can be restored or re-cored, but some turn out better than others. That's why Glen-ray ships a radiator to the cus- tomer for approval before it collects the bill. "That's just to make sure the customer is satisfied," says Schirmer. Glen-ray's 26-inch Chrysler licensed reproduction small-block radiator is a popular offering. It comes in three-row standard cooling and three-row max cooling models. The small-block version comes with a cap, overflow hose, cor- rectly marked mounting bolts, fan shroud attaching hardware, transmission cooler fittings (if needed) and correct upper and lower radiator hose clamps. The reproduction 26-inch big-block radiator also has three-row standard cooling or three-row max cooling options and includes a cap, overflow hose, cor- rectly marked mounting bolts, fan shroud hardware, transmission cooler fittings (if needed) and correct upper/lower radiator hose clamps.

Building a radiator that fits into a one-of-a-kind, A shiny, dent-free finish is part of Glen-ray's restoration process. Some of the Mopar radiator parts that Glen-ray has made under license.
