2005 Cadillac DeVille Parts Questions & Experts Answers

• Q: How to replace the coolant reservoir on 2005 Cadillac DeVille?

  A: Start by draining part of the engine coolant before moving forward with surge tank replacement. Evacuate the fluid from both the surge tank inlet hose and the Coolant Level Sensor connector . Start by taking out the secondary air relay bracket mounting nuts followed by removing the secondary air relay bracket. The j 43181 quick connect release tool (J 43181) helps users release the quick connect fitting which connects the surge tank outlet hose. Disassemble the surge tank by removing its retaining screws and nuts then extract the unit from its mounting studs. Mount the surge tank onto its mounting studs before installing the surge tank bolt and tight it to 6 nm (53 inch lbs.). Begin by installing the surge tank nuts on the studs then tighten them to 6 nm (53 inch lbs.). The outlet hose of the surge tank should receive the quick connect fitting at its location on the surge tank with a complete seating of the fitting. Mount the secondary air relay bracket at the studs using two secondary air relay bracket nuts which require tightening to 6 nm (53 inch lbs.). After connecting the connector to the Coolant Level Sensor you should reconnect the surge tank inlet hose to the surge tank before filling the cooling system.
