Are there any coolant system vents (other than the radiator cap) to open when draining/refilling the coolant? These vents exist on some vehicles to "burp" the system. Thanks

 

I don't think this should be in the DIY thread....but to answer your question....When draining all of engine coolant in the system, open radiator drain plug, remove radiator cap and then open water drain plugs on cylinder block. There should be an air relief plug on the radiator left side and an air relief plug on the heater hose for refilling purposes.
