95 ford probe car runs ok but blows whitish blue smoke as accelerate

That is probably the head gasket leaking. White smoke is from antifreeze going through the exhaust. The engine compression is pushing the water out of the radiator.

HI, we have 2002 Nissan Primera that is losing water but not onto the ground beneath the car. There isn't any oil in the water or vice versa, but we can't see where the water goes? Any ideas

check the water level in the bottle. If the radiator cap is faulty it will allow excess hot water into the bottle but on cooling down the water is supposed to be sucked back into the radiator. It gets to a point where low water in the radiator will not be pushed out and you get the impresion that you are loosing water If this area checks out the only other place is through the combustion chamber as steam indicating a head gasket or cracked head./ Check the radiator cap first and while you are at it with the engine hot fill the radiator right up and run the engine at idle. If you see air bubbles blowing out the water intermittently put your money on that is where the trouble is. hrad gasket or cracked head

Water comes out of cap after I stop

When you stop the engine heat is still being generated inthe engine from all the hot bits. As there is now no water circulation through the radiator these cause local boiling which pushes the watemp right up. The pressure generated by this rise in temperature opens the cap expelling water. I would find the cause of the engine running hot to start with. Faulty fan /fan motor,failed viscous fan hub, thermostat blocked radiator are a few starting points

Water failure to engine vstra 1.6 16v 1999

There are several possible causes. Start with the cheapest solution.

1. If you are using water instead of anti-freeze, the water will boil and will get pushed into the overflow tank. Replace the water with anti-freeze.

2. The radiator cap could be bad, allowing hot coolant to exit the radiator and flow into the overflow tank. Have the cap tested or just replace it. It's a cheap item.

3. A leaky head gasket is allowing combustion gases to pressurize the cooling system, which pushes the coolant past the radiator cap. You can easily diagnose this by carefully removing the radiator cap and, with the engine running, observing if there is a continuous stream of bubbles in the coolant. These bubbles are exhaust gas, and you will need to replace the head gasket.

Overheating. Water pump appears to be good to go and thermostat was changed and the engine seems to be pushing the temp up when climbing a hill. I jumpered the fan relay switch so fan runs every time I...

The core pipes in your radiator may be blocked with particles of junk. There is no easy way to clear them other than to remove the top and bottom tanks of the radiator and push a rods through the individual pipes to push out the junk.
You could try back flushing the radiator, that is force the water back through the radiator the oposite way it normally goes with a high flow hose.

Have 2000 year sedona 2.9 ,blowing water in expansion bottle all

That's what it sounds like, a blown head gasket. Every time the piston compresses it pushes the air fuel mixture into your cooling system through the broken head gasket. Try running the engine with the radiator cap off or lose and look and smell for gas in your radiator overflow tank. Good luck and hope this helps.
