2002 Buick Regal MAP Sensor

You need to remove the upper Intake Manifold, the generator brace, the drive belt tensioner, the heater water bypass inlet pipe, the EGR outlet pipe, and the radiator inlet hose, disconnect the ECT sensor electrical connector, remove the generator brace bracket bolts, the generator brace bracket, the evaporative emissions canister purge solenoid valve, the lower intake manifold bolts, the lower intake manifold, the lower intake manifold seals and the lower intake manifold gaskets, and clean the lower intake manifold mating surfaces and the intake manifold bolts and bolt holes of the adhesive compound.

You should not route flexible components (hoses, wires, conduits, etc.) within 50 mm (2 in) of moving parts unless flexible components can be securely fastened.

You should not remove the radiator cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if the radiator cap or surge tank cap is removed while the engine's arid radiator is still hot.
