• Q: How to replace the oil cooler on 2006 Buick Rendezvous?

  A: Draining both engine oil and the cooling system remains the first step before removing the Oil Filter. First remove the outlet hose from both the thermostat bypass pipe and the Oil Cooler before unclamping it at the thermostat bypass pipe. The Oil Cooler pipe bolt at the engine mount strut/air conditioning (AC) compressor bracket needs removal before completing the extraction of the Oil Cooler pipe with hoses and the Oil Cooler connector. Position the Oil Cooler inlet hose clamp if necessary then unfasten both the inlet hose from the fitting and the Oil Cooler hose fitting. Use thread sealant gm p/n 12346004 (Canadian P/N 10953480) or equivalent to treat the Oil Cooler hose fitting threads when needed before installing the fitting with a tightness limit of 19 nm (14 ft. Lbs.). First, connect the Oil Cooler inlet hose to its fitting then clamp the inlet hose before mounting the Oil Cooler while tightening the inlet hose clamp. Secure the Oil Cooler connector with a torque of 50 nm (37 ft. Lbs.) before adding the Oil Cooler pipe with attached hoses to the engine mount strut/ac compressor bracket, securing it with a bolt then tightening it to 10 nm (89 inch lbs.). After positioning the outlet hose clamp at the thermostat bypass pipe, reconnect the Oil Cooler outlet hose to both the Oil Cooler and the thermostat bypass pipe. After the installation of a new Oil Filter complete your work by adding fresh engine oil and filling the cooling system.
