1991 GMC Suburban 2500 Question: why is air bubbling back through coolant resevoir



dwallyt, 6.2L V8 Diesel, Waynesboro, VA, December 11, 2010, 05:45

air bubbles back through coolant resevoir constantly pushing coolant into the reservoir & not allowing it back into cooling system thus causing "low coolant" light to come on.this happened after an overheating episode when i noticed my temp go up to about 210 briefly. i immediately replaced thermostat & radiator which was leaking a little. the bubbling reservoir started after these repairs.
