• Q: How to replace the Heater Core on 2001 Chevrolet Venture?

  A: The first step to replace a Heater Core requires draining the cooling system content. People should detach the Wiper Motor module and Brake Booster vacuum hose before moving them to a new position. Clear the air cleaner cover and intake tube while disconnecting throttle and cruise control cables in a way which avoids damaging cable housing forms. The replacement starts with removing the transmission fluid filler tube as well as disconnecting both heater hose quick disconnects from their respective inlet and outlet pipes. The hose clamp pliers (J 38185) should be used for heater hose clamp disconnection from both heater hoses before hose removal from the Heater Core. Seal the inlet and outlet pipes to avoid coolant spillage. First cap the Heater Core pipes before removing the Heater Core cover clamp screw to take out the Heater Core from the hvac module. The new Heater Core installation begins with placing it inside the hvac module before tightening the Heater Core pipe retaining clamp screw to 1.6 n.m (14 lb in). The installation of the Heater Core cover includes heater hose attachment to the Heater Core while the hose clamp pliers (J 38185) help position the heater hose clamps. Fasten the heater hose quick connects to the inlet and outlet pipes before reinstating the transmission fluid filler tube. Conclude the repair by reinstalling the intake hose and air cleaner cover while connecting cruise control and throttle cables to the tbi bracket and re-attaching the wiper module and vacuum hose to the Brake Booster then fill in coolant.
