Having problems with your 1999 Buick Century ?
Should i bleed the thermostat to keep light from blinking for coolant
NO cooling systems do not need to be bleed they are vented into the recovery bottle . When the coolant expands when hot it goes into the recoverry system and when it cools it gets drawn back into the raitator through the hose that comes from the radiator and goes to the recovery bottle . Dose the light say ckeck gauges if so the problem is eighter with the antifreeze or the engine oil check the level of bolth . If the oil is OK and full then try flushing the cooling system . Antifreeze olny last about 5 years and chevy uses that orange antifreeze if you change it make sure the new stuff is compatable with chevy standards it should say on the container Good luck
