Losing water - Cars & Trucks

If there is water in the oil, it wouldn't last long under the heat/pressure of the engine, so if you are seeing water it must be super fresh. Are you losing coolant? If so, then i'd suspect water pump/water pump gasket if you never had that replaced. It could be head gasket, but you would probably experience a consistent coolant loss with maybe loss of power or misfiring. You can check with a pressure/leak down test for head gasket. Either way, if you are losing coolant I'd check water pump. If you aren't losing coolant than it can't be the water pump or head gasket really letting "water" in.

No. There's a myriad of possibilities.
There's either a leak.
Faulty radiator or coolant tank cap.
leaking water pump.
Damaged head gasket.
Air lock.
etc...

is it losing water? if not is your fan kicking on? if losing water, place piece of cardboard under veh at night to help pinpoint where water is leaking. if not losing water and fan does'nt come on check fan relay. if loses water and don't see leak over night on cardboard, then water pump is leaking thru weep hole but only after heats up and pressure is on need to replace water pump.

Sounds like a thermostat problem!!

try the thermostat, located on the top radiator hose. top side of engine. also does it steam?? does it lose water but no leak, does the heat blow hot? if your heat isnt hot and it steams and loses water you may have a cracked head or head gasket. if you have heat, doesnt lose water and doesnt steam it may also be your water pump. most pumps will leak visibly from the weep hole when running

probably a head gasket. could be a cracked head but its unusual for aluminum heads to crack.

check the water pipe nipple. It's a plastic one underneath the the camshaft. There's a hose connected to it and it breaks of slowly.

i suspect the water pump..

Probably is a leak in the head gasket between the water jacket and the cylinder or possibly a cracked head. Either way, it's not cheap even if you are fixing it yourself. Rick

If your oil is white looking on the dip stick, you will have serious damage inside the engine.
