May be air in your cooling system. Unless you have a vacuum to put coolant in, it is very hard to get all the air out. It will cause your engine to heat up quickly and your temp gauge to be very erratic. If water is missing steam will cause that.
No. It will keep running until the engine is ruined.
it should start at cold
needs a new thermostat or water pump
The engine cooling fan will continue to run because the engine is hot. Once the engine has cooled down the fan will shut off. If it never shuts off you may have a bad temp switch or relay.
195 is the thermostat that goes in a V6.
fix the issue that's making it over heat
The engine coolent may be low enough that sensor is not surounded with coolent when engine is not running.
Just next where the radiator hose goes in to the engine. (Driver side)
It has 2 independent sensors in it, one goes to the cluster for the coolant temp gauge. The other goes to the DME for controlling the fuel mix, engine timing, cam timing, as the enging goes from cold to operating temp. It effects performance, MPG, and emissions.
the coolant goes through the radiator too fast to be cooled sufficiently. a thermostat will help get the engine to operating temp and the let only enough coolant through to keep engine at that temp. this slows coolant down enough to be cooled properly.
The engine temp sensor is on the front of the engine, next to the thermostat housing.The engine temp sensor is on the front of the engine, next to the thermostat housing.
Bad things. Internal engine temp goes up, parts wear MUCH faster, and your bearings fail. Long of the short, your engine stops working.
