Check the vans entire cooling system including the temp sending unit, cooling fan, thermostat an water pump. One of these is probably bad and needs replacing.
Your oil is hot.
No. All you get is smoke and steam. Not smoking stops the smell. Running water like that waste water as well.
If it shows hot on the gauge and it is not hot, there is a gauge or sensor problem.
You probably could A) replace the gauge or B) take it to a dealership and have them look at it
If the gauge is reading hot and the car is running normal temperatures, the water temperature sensor needs replaced.
You can check the temp. gauge operation by removing the temp. gauge sending unit plug and touching it to any engine ground with ignition on but the Van not running. The gauge will go to hot right away, if it is working. The temp. gauge sending unit is located on the drivers side of the engine at midpoint just below the exhaust manifold. It will have a single wire running to it and be plugged into the sending unit.
That depends on what the car is supposed to run at.
Is it smoking a lot? If so you probably have a blown gasket. If it's not smoking, check the thermostat. I don't get how a car could be not getting hot but using a lot of water and the temp gauge is going up. Have you checked for leaks?
Possibly a leak in the coolant reservoir bottle.
Low coolant? Thermostat not opening?
check the coolant temp sensor
Your engine coolant temperature gauge has a sensor ( there is also a engine coolant temperature sensor that is used for the computer / PCM )
