What causes coolant to go out of an engine?

If you suspect coolant has mixed with the engine oil, repair the problem as soon as possible. Antifreeze in the oil can damage the cylinders and pistons. Operating the engine at higher the normal temperature may cause coolant loss.

Can a blown head gasket cause a coolant leak?

Just like a combustion leak into the cooling system, a blown head gasket, cracked head or block, or faulty oil cooler lines can cause coolant to leak into the engine oil. Often, you can tell coolant has leaked into the lubricating system by the appearance of a milky white substance on the dipstick or under the valve covers.

What happens when a head gasket fails in an engine?

The same failure can also cause exhaust gases to enter the oilways and pressurise the crankcase, causing lubrication issues and excessive engine wear. If a head gasket has failed between the waterway or oilway and the outside of the engine, the result can be a simple coolant or oil leak.

Is the GM 5.3L V8 engine eating up too much oil?

Where does the coolant go in a Chevy Suburban 5.3?

It had the 4.8 liter motor, but is basically the same as the 5.3. There is an issue with some of these motors, cracks develop in the head underneath the valve cover and coolant runs out of these cracks and down the oil drain ports in the head, straight down to the oil pan. GM is doing nothing about this.

Where does the oil leak go in a Chevy Suburban?

There is no water in the oil. Well if it is leaving, it is either leaking on the ground, or into the passenger compartment (as in a heater core leak), or into the engine oil, or into the intake manifold. Into the intake manifold would then be spit out the exhaust and typically you notice it with white smoke (moisture) after the car has warmed up.

What causes coolant to leak into the engine?

A garage that handles radiators and a/c can easily troubleshoot your coolant problem. Could be a leaky hose connector, leaking water pump, radiator leaking, heater core leaking (a 2nd if you have the rear heater), leaky overflow tank, one of many hoses leaking, or a leaky head gasket where the coolant is leaking into the engine.
