All Forge Motorsport products come with a limited lifetime warranty. All warranty claims must be accompanied by the original proof of purchase to enable us to help you. Failure to supply this proof will result in your claim or enquiry being denied.
For further information, please contact our customer service team.
Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.
