Oil Coolers / Radiators / Heat Exchangers
![stomski stomski](/uploads/images/car_logo/stomski.gif)
Some GT3 engines are experiencing oil-to-coolant intermixing. While there are potentially several sources of intermixing, faulty engine mounted oil-to-coolant heat exchangers are a major source. Now, with STOMSKI RACING's GT3 Heat Exchanger Tester set, you can confirm if your exchanger is faulty and needs replacing, or whether the source of the contamination is elsewhere. This set of CNC machined gauge blocks is machined from 6061 aluminum for years of service and comes complete with all gauges, seals, valves, and hardware.
Also works on the GT2 and 996/997 TT engines as well.
