2003 Buick Rendezvous Thermostat Parts Questions & Experts Answers

• Q: How to replace the thermostat on 2003 Buick Rendezvous?

  A: You need hose clamp pliers (J 38185) among other tools for Thermostat replacement. The cleaning process starts with the removal of both air cleaner assemblies and ducts which enables coolant draining until the Thermostat area stays submerged. It's essential to start by removing both the crossover Exhaust Pipe as well as the Radiator Hose from the Thermostat Housing. Smith begins by removing the Thermostat Housing bolts while cleaning all sealer from bolt threads until he can safely remove both the housing and gasket. First wipe down the surfaces that will mate with the Thermostat and then put in the new Thermostat. Reinstallation of the Thermostat Housing requires first placing the gasket then securing the bolt with 25 nm (18 ft. Lbs.) of torque. Install the Radiator Hose onto the Thermostat Housing then reconnect the crossover Exhaust Pipe and reinstall the air cleaner along with its duct assembly. The cooling system completion follows this step.
