SOURCE: where is the drain plug for coolant system on 1999

on one side of the radiator near the bottom is a petcock. open the petcock to drain. Take the radiator cap off to do this to allow it to vent so it will drain out.
If you cant find it, remove the bottom hose off the radiator. This is messy but effective.

Fig. 1: The thermostat is located in the lower radiator hose on the 2.2L engine (click image for zoom)



2.3L and 2.4L Engines
(see Figure 7)

When adding coolant, it is important that you use GM Goodwrench DEX-COOL® (orange colored, silicate free) coolant meeting GM specifications. On these vehicles, if silicated coolant is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner; at 30,000 milee or 24 months.
  1. Disconnect the negative battery cable.
  2. Properly drain and recover the coolant to a level below the thermostat.
  3. Unfasten the cover-to-outlet pipe bolt, which is accessible through the exhaust manifold runners.
  4. Raise and safely support the vehicle.
  5. Disconnect the radiator and heater hoses from the outlet pipe.
  6. Unfasten the outlet pipe-to-oil pan bolt and the cover-to-outlet pipe bolts.
  7. Remove the thermostat, then clean the old gasket material from the mating surfaces.

To install:
  1. Position the thermostat in ite correct location, then install the cover-to-outlet pipe bolt. Tighten the bolt to 10 ft. lbs. (14 Nm).
  2. Install the outlet pipe-to-oil pan bolt. Tighten the pipe-to-oil pan bolt to 19 ft. lbs. (26 Nm) and the pipe-to-transaxle bolt to 40 ft. lbs. (54 Nm).
  3. Connect the radiator and heater hoses to the outlet pipe.
