temp/cooling sys. please read need help!

Have your radiator cap, viscous and thermo electric fan and water pump checked.

There is a burping valve on the thermostat( a 8mill bolt that sticks out of the top of themostat). When topping off always open the burping valve untill h2o or coolent flows out. Tighten up bolt, but keep resivor cap off and start car. Once 735I is at running temp open burp valve if only fluid runs out, without presureized air spray. Close it up and top off resivor and tighten up lid. If there is still air in system keep filling and burping untill air is gone. Don't fill resivor to top while motor is cold. This can potentailly split resivor if overflow is cloogged or nonopp. Good luck
