Q: How to replace the engine oil cooler on Buick Rendezvous?
A: The Engine Oil Cooler replacement process starts with draining cooling system fluid and engine oil before taking out the Oil Filter. First detach the outlet hose from its position on both the thermostat bypass pipe and Oil Cooler before repositioning the hose clamp on the bypass pipe. After detaching the Oil Cooler pipe bolt at the engine mount strut/air conditioning (AC) compressor bracket remove the Oil Cooler pipe along with hoses and then proceed to detach the Oil Cooler connector. Repaint the inlet hose clamp at the Oil Cooler and detach the hose from both the fitting as well as the Oil Cooler hose fitting. Before installing the Oil Cooler hose fitting you must apply thread sealant to the threads if needed before torquing it to 19 n.m (14 lb ft). Position and install the inlet hose by clamping it to the fitting of the Oil Cooler. Position the inlet hose clamp around the Oil Cooler before attaching the coolers to their installation point. Attach the Oil Cooler connector first and tighten it to 50 n.m (37 lb. Ft). Then install the Oil Cooler pipe with hoses and bolt at the engine mount strut/ac compressor bracket and tighten it to 10 n.m (89 lb. In). Reposition the outlet hose clamp at the thermostat bypass pipe while reattaching both the Oil Cooler outlet hose and the thermostat bypass pipe. You need to place a brand-new Oil Filter then add engine oil and finally complete the coolant fill-up.
Q: How to replace the engine oil cooler on Buick Terraza?
A: You need to drain the cooling system first before you remove the radiator air baffle when replacing the Engine Oil Cooler unit. A suitable drain pan should catch dripping liquid while you remove the Oil Filter. You must reposition the Oil Cooler outlet hose clamp on the Oil Cooler before you detach the hose from its position on the cooler fitting. Start by unclamping and pulling the engine mounted Oil Cooler inlet hose off its engine connection. The first step should be disconnecting the Oil Cooler connector before removing the Oil Cooler and its gasket from the Oil Filter adapter. The first step is to clamp and detach the Oil Cooler inlet hose from its position at the Oil Cooler. The installation process requires Oil Cooler inlet hose installation to the Oil Cooler and secure the Oil Cooler inlet hose clamp in position at the Oil Cooler. Position the new Oil Cooler gasket onto the Oil Cooler before attaching the gasket along with the Oil Cooler to the Oil Filter adapter. Be sure to follow all fastener notice requirements. Secure the Oil Cooler connector with a torque of 25 n.m (18 lb ft). Position the Oil Cooler inlet hose clamp at the engine as you install the outlet hose to the engine fitting. You should attach the Oil Cooler outlet hose to its fitting while installing the outlet hose clamp on the Oil Cooler. Fasten the Oil Filter installation with 30 n.m (22 lb ft) torque. After removing the Oil Filter drain pan reinstall the radiator air baffle then fill the cooling system as well as checking and filling the crankcase if needed.
