there is either a pocket of air or the car is burning the coolant if there is no leak. check inside the car for any coolant leaking under the dash if so the heater core has a hole in it.
see this causes and fix it. God bless you Water pump -- A bad shaft seal will
allow coolant to dribble out of the vent hole just under the water pump
pulley shaft. If the water pump is a two-piece unit with a backing
plate, the gasket between the housing and back cover may be leaking.
The gasket or o-ring that seals the pump to the engine front cover on
cover-mounted water pumps can also leak coolant. Look for stains,
discoloration or liquid coolant on the outside of the water pump or
engine. Radiator -- Radiators can develop
leaks around upper or loser hose connections as a result of vibration.
The seams where the core is mated to the end tanks is another place
where leaks frequently develop, especially on aluminum radiators with
plastic end tanks. On copper/brass radiators, leaks typically occur
where the cooling tubes in the core are connected or soldered to the
core headers. The core itself is also vulnerable to stone damage.
Internal corrosion caused by old coolant that has never been changed can
also eat through the metal in the radiator, causing it to leak.
Most cooling systems today are designed to operate at 8 to 14 psi.
If the radiator can't hold pressure, your engine will overheat and lose
coolant. Hoses -- Cracks, pinholes or splits
in a radiator hose or heater hose will leak coolant. A hose leak will
usually send a stream of hot coolant spraying out of the hose. A
corroded hose connection or a loose or damaged hose clamp may also allow
coolant to leak from the end of a hose. Sometimes the leak may only
occur once the hose gets hot and the pinhole or crack opens up.
indicates an air lock in the cooling system
could be from a failing head gasket ( do a compression test)
have a coolant pressure test done to find the leak
possible a water pump seal leaking when running
check sump oil for greying color ( failure of the housing behind the pump impeller
This is due to leak in the radiator or the hose or the water pump. In all cases your observation is MOST important as the visual check will give you the exact point of leak. fill up the radiator with coolant if there is a low level , check the pressure cap on the radiator. now if the engine is heating too much then the tuning /timing must be looked into. other wise the leak can be seen and the part replaced be it the radiator, hose or the water pump or bearings.
evidently there is a leak. I would check the hoses, thermostat housing, drain **** for radiator and the fins on the radiator for fluid leaking. The water pump housing and at the weep hole is another place to check. If it is leaking from the fins they do sell a stop leak. Hope this helps tim
It's a 99% chance of water pump leak or the housing at the timing chain that the water pump sits on. Water pumps can and do leak one minute then seal themselves. A cheap fix most use is go to a 7 lb pressure cap on the rad.
