A well maintained Pontiac Sunfire with the 2.2L 4-cylinder engine should be easily be able to reach 200,000 miles as designed. This will require you to be active in maintaining its engine oil intervals & level, transmission fluid and filter changes, coolant flushes, and remembering to replace belts, PCVs, air and fuel filters.
The coolant level sensor in the coolant reservoir detects the coolant level is low. The coolant system must have a leak in it somewhere. Have a trusted mechanic diagnose it soon before you do damage to the engine.
there is a sensor in the bottom of the coolant bottle, change this and you should be o.k. tap the sensor with a screw driver it will go out uts just stuck
To check the coolant level of a vehicle first see look for the overflow reservoir. There should be a coolant dipstick with a level gauge on it. Remove it from the reservoir to see the coolant level.
The coolant level is set by the level in the coolant reservoir. There is a line for the level if the engine is cold and a line for if the engine is up to temperature. You should fill it to the corresponding line.
bleed the brakes. check fluid level
Open drain plug at lower end of radiator Run engine to Normal operating temperature with heater on -no higher When draining stops -- close drain plug Refill radiator slowly to prevent system from becoming "airbound" Start vehicle - bring up to normal operating temperature with heater and re-check coolant level
Check the engine coolant... Is it full? yes coolant level is full
The coolant level is checked at the coolant tank in the passenger front corner of the engine compartment . The coolant level should be up to the cold mark when the engine is cold . The radiator should be full so its covering the top plate .
there should be a clear white juglike thing that says coolant on the lid... look at the liquid level on the container
There is a sensor that is in the overflow bottle that may be bad causing the "low coolant light" to illuminate. The coolant level switch is located on the bottom side of the coolant tank. The switch contains a reed switch and a magnetic float. When the coolant level is normal, the float rests away from the reed switch, causing the switch to be open. When the coolant level decreases in the coolant recovery tank below a specified level, the float rests on the reed switch and the switch closes, illuminating the LOW COOLANT light. The coolant level switch is a part of the coolant tank. If the switch needs to be replaced, the coolant tank must be replaced.
It should be located in the coolant overflow resivoir.
