• Q: How to service and repair the heater core on 2002 Chevrolet Corvette?

  A: The service and repair process for the Heater Core starts with hvac module disassembly and continues by unscrewing both the Heater Core outlet cover screws and removing the outlet cover. First remove the Heater Core cover screws while discarding seals (1,2,3) from the cover along with the outer seal from the core before removing the cover. The servicing begins with removing the Heater Core retaining clamp screw and its retaining clamp then unfastening the Heater Core pipe retainer clamp screw before removing the Heater Core from the hvac module case - lower. Remove all seals and retainers collectively from the hvac module case - lower so that only the lower and upper assembly parts remain. You can use a flat bladed tool to open the retaining tab before accessing the Heater Core pipe retainer clamp. Install the Heater Core pipe retainer clamp to Heater Core pipelines by aligning the depression in the clamp with the ridge on one of the pipes and then secure the clamp. Fasten the new Heater Core side seals , upper seal , center seal , and lower seal to the hvac module case - lower before adding the Heater Core itself. Fasten the Heater Core pipe retainer clamp screw with 1.6 n.m (14 lb in) torque before attaching the Heater Core retaining clamp by screw. The clamp screw requires a torque setting of 1.6 n.m (14 lb in) as well. The next step involves installing new Heater Core outer seal together with cavity seals (1, 2, 3) onto the Heater Core cover before fastening the cover and its screws to 1.6 n.m (14 lb in). Reinstall the hvac module after installing the Heater Core outlet cover along with its screws while tightening all hardware to 1.6 n.m (14 lb in).
