Information
Radiator oil cooler rubber mount.
This radiator oil cooler rubber mount is an replacement rubber isolator designed to support the radiator oil cooler on classic Porsche 911 models 1978–1989.
It cushions and secures the radiator oil cooler within the engine bay, reducing vibration and noise while helping maintain correct positioning of the cooler assembly. It matches original factory specifications so it installs directly into the intended mounting points with no modification required.
Sold each.
Fits:
Porsche 911 1978 - 1989
Diagram ref no 13B
The rubber mount absorbs engine and road vibration, helping to isolate the oil cooler from harsh movement and protect it from stress and fatigue. It keeps the cooler properly aligned, preventing undue strain on hoses, fittings, and brackets.
Built to support the weight of the radiator oil cooler and dampen dynamic forces, this mount mitigates vibration transfer throughout the engine bay. It ensures the oil cooler remains stable under thermal expansion, engine torque, and chassis motion while helping minimise noise and wear.
Over time, rubber mounts deteriorate from heat, age, and exposure to oil and road contaminants. A worn or broken mount can allow excessive cooler movement, leading to hose fatigue, oil leaks, and compromised cooling performance. Replacing it with an OE-match mount restores proper support and prolongs the life of your oil cooler system.
When to replace:
• Visible cracks, splits, or deformation in the rubber
• Loose or sagging radiator oil cooler
• Increased vibration or noise from the engine compartment
• During oil cooler removal or engine work
• As part of preventive maintenance

Information
Heat exchanger pressure tester for Porsche 996/997 Turbo/GT2/GT3
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.
