2002 Buick Regal Throttle Body Mounting Gasket

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.

The procedure is to remove the engine intake air snorkel assembly, the bolt from the t/b support bracket, loosen the bolt from the t/b support bracket, move the t/b support bracket away, remove one of the 3 t/b nuts, apply thread locker, install a new t/b spring nut and tighten finger tight, reinstall the t/b support bracket into position, reinstall and torque the t/b support bracket bolt to 10 Nm, torque the t/b support bracket bolt to 10 Nm, remove the vehicle radiator cap and an appropriate quantity of coolant pellets, install the crushed pellets, add coolant and reinstall the radiator cap, and install the GM Identification Label.
