The original version of this system was so efficient at actively eliminating trapped air in the DeLorean cooling system; the symptoms associated with a number of engine-related issues were effectively masked during normal operations. This caused additional effort for diagnostic purposes, and often resulted in removal of this system. The current revised system incorporates an exclusive inline shut-off valve that will allow the entire system to be deactivated during normal operation of the engine, and activated periodically for cooling system maintenance and repairs to facilitate elimination of trapped air. This feature will allow normal engine diagnostic procedures to be performed effectively without the necessity of complete self bleeder system removal.
This upgrade, in its original form, is designed to eliminate trapped air from the upper areas of the engine. Most self-bleeder kits do a great job of performing this function, but this isn’t the only place that air can become trapped in the DeLorean cooling system. During routine maintenance of the cooling system, or as a result of unexpected coolant loss due to a leak, air can also be introduced into the radiator or the heater core portions of the system. This trapped air may not be eliminated by the typical self-bleeder kits, and must be removed as a separate step. The normal technique for releasing this trapped air is to remove the small air bleed hose from a hose barb on the radiator. When the hose is disconnected, any air in the radiator will escape, until coolant flows from the connection, usually all over you! And if your car has an original radiator, great care must be taken to avoid damaging the plastic hose barb. DPNW has gone one step further with its self-bleeder kit by adding an exclusive in-line system for eliminating trapped air in the radiator quickly and easily. Includes K1017DP (the DPNW Wings-B-Cool™ Radiator Bleeder Kit), hoses, fittings, clamps and detailed installation instructions and diagrams.
