R. Shepler Posted March 22 Report Share Posted March 22 started the car hot in the driveway and all the coolant was immediately expelled from the system. no signs of leakage were visible before, but i did notice the reservoir was low a week ago and added coolant, maybe a quart. I've checked the oil and there is no sign of water in the oil. 1 Quote Link to comment Share on other sites More sharing options...

No mention of year or engine, but it sounds like a hose failure that started as a leak. Quote Link to comment Share on other sites More sharing options...

Time for some diagnostics - based on the sparse info provided best do a compression test - a blown head gasket could cause over-pressurization of the coolant system and expel the coolant.
