SOURCE: 2001 dodge stratus engine temperature gauge spikes occasionally

Look for a loose connection to the temperature sender unit on the motor.
If all connections OK, you may need a new temp sender unit.

SOURCE: temperature gauge fluctuating surges

That sounds like the classic symptoms of a cracked ECTS (temperature sensor). It is located on the head near the upper radiator hose and battery. You will see two wires (likely a yellow and a black) going to a small sensor hiding in a little cubby hole. If you pull off the connector (there are two points that if you squeeze it lets the connector come off) you will probably see that the connector is corroded because the plastic body of the original ECTS cracked and let a small amount of coolant into the connector. The ECTS is only about a $10-15 part, be sure to get the updated one with a brass body. Then the hard part is you will likely need to get a new connector, one of the best places for that is a junk yard, the temp sensor for the transmission and the air temperature sensor near the air filter use the same connector. When putting this in be sure to solder the connections and cover that with heat shrink tubing. There are video's from Richpin06A on youtube that will show you how if you have any doubts. The saturnfans forum is a great place for info too,

SOURCE: zigzag light on megane scenic dashboard comes on

this exact problem on a megane coupe is caused by a small air pipe that connects to a 2 inch wide black box that is located under the bonnet near the windscreen on the passangers side. the zigzag light indicates an electrical fault (in this case lack of compression and will affect your revs) if you find this pipe and it has snapped off. the reason for this may be that your engien is lose and moves. grab the engien with 2 hands and see if you can wobble it with allot of play. if so your engien mountings need replaceing. you may also experiance juddering in low gears

Why does my temperature gauge keep going up and down


An accurate temperature gauge will always fluctuate because the temperature in the engine fluctuates.

Usually the only time this is really noticeable is when the engine has been working hard and suddenly has to wait at a junction or similar and the gauge can rise considerably.

You didn't mention by how much the gauge fluctuates?
As long as it remains approximately in the normal zone it is acceptable but if it climbs into the hot zone or falls into the cold zone it is not acceptable and the cause should be investigated as soon as possible.

Truck never reaches operating temperature


low operating temperatures is an indication of an air lock in the cooling system
gauges need the sender unit to be fully immersed in coolant to work but if they are not then the variable resistance material in the sender bulb cannot accurately relate to the coolant temperature
example if you have leak develop in a good system and you do not regularly scan your gauges like a good drive will do. it is possible that you will smell a dying engine yet when yo look at the gauge it will be reading cool to cold because the coolant has dropped to a point where the sender is no longer in contact with the coolant

What causes my temperature gauge go from high to low


IF your symptoms are when driving , the temp gauge acts normal rising slowly. Then all of the sudden it goes high and a second or two later it goes back to normal. Then you have low coolant in the engine. The reason this happens is because of air pockets. Air pockets are much hotter than the coolant. Check for coolant leaks...

Temperature gauge is fluctuating while driving.


I'm thinking the coolnat level is low, and this might be caused by a bad head gasket - At least $800 to fix - sorry.
