Engine Coolant Service Fill Procedure (Without)
(without Engine Vent Line)
1.
Close the radiator drain valve and remove drain tube.
2.
Install all engine block drain plugs if previously removed. Use pipe sealer when installing drain plugs.
3.
When adding engine coolant, it is important that GM Goodwrench DEX-COOL(R) (orange-colored, silicate-free) coolant meeting GM
specification 6277M be used. If silicate-containing 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 50,000 km (30,000 miles) or 24 months.
4.
Open both bleeder valves. One is on the heater return pipe and one is on the water outlet (behind air intake plenum).
5.
Fill the cooling system through the surge tank until coolant is expelled out both bleeder valves.
6.
Close bleeder valves.
7.
Top off coolant level in surge tank to a level even with the flat horizontal wall below the vent lines.
Important:
Leave surge tank cap off.
8.
Start engine.
9.
Open water outlet bleeder valve and leave valve open until a solid stream of coolant is expelled, then close valve. Repeat this every 3 minutes until
the thermostat opens.
Important:
Thermostat. is considered open when upper radiator hose is hot at radiator connection.
Important:
Turn HVAC controls to "heater," full hot and check for warm air during the first five minutes after engine start. If no hot air is present, start
procedure again at Step 4.
10.
Top off engine coolant, if necessary, to the same level as in Step seven (7).
11.
