coolant overflow sensor help

[jaybo300]

I was filling up my coolant and found a sensor with the wires cut. The sensor is fed into the bottom of the overflow tank and I don't know where the wires from the sensor lead to. Does anyone know where they lead to. I don't know why it was cut. Is that the coolent level sensor? Any help is appritated. I have a n/a 98 eclipse gs.

mmm possibly the ecu for coolant readings, and maybe a ground. vfaq.com may tell more about pinouts to the ecu.

What coolant readings are you hypothesizing about?

OP, it is for the coolant level sensor. The pigtail for it is a part of the loom on the passenger side of the vehicle. Check the FSM if you need the wiring color/pin outs. It trips the dummy light in the cluster notifying you of a low coolant condition.

Ah yes the resivior i thought of the thermostat housing, oh well, exactly same problem i had i just traced it down to the wire in the harness on in front of the radiator chassis. I would start tracing wires.

Actually after some dusting off of old threads, the NT models only had those in 95/96 model years. So if you are looking for a pigtail that does not exist, do not worry. What might have happened was the previous owner replaced the coolant overflow reservoir with a junkyard piece from an older model or cloud car.

There are no ECU connections for it: it was only a dash light that came on, similar to the coolant temperature gauge in your cluster.

Guys could someone, explain why a 98 gst has no coolant sensor??? the reservoir doesnt get any wires... and i see nothing around... maybe my gst didnt come with it? Its weird because as far as my VIN number says its a premium one so it should have it... If does not, is there any way to make it work? buy a reservoir with a sensor and connect it somewhere.. and tell the ecu that exists?? i just want my light to go on!!! haha. Some times it gets empty... there might be leak, in the reservoir cap as it got burned from previous owenr and enters a little air (by the way that cap its impossible to find unless i buy a new reservoir, im from argentina...)
thanks a lot!!

Yes, but not in the 420A forums. Ask your question here:

Sorry im learning, ill post there and wait your answer!!!

So why is this feature canceled after 96? It seems very helpful to me.

 

[VelocitàPaola]

All of the 1995-1999 420A cars that I know have it...

 

[Th3DooM]

I took out my coolant reservoir enough times to know there isn't a sensor. Does anybody has a picture of it?

You're right, my mind was elsewhere when I answered. I'm not sure anyone can answer your question about why it was omitted other than a Mitsubishi/Chrysler engineer.

Hey i've got some photos but no answer for anybody because my wire was cut also.
97 rs had no sensor
97 gs has one

 

[dsmcrzy]

My 96 RS doesnt have one.

 

[LxiMax]

My 95 GST has it. It no worky though due to the wires being corroded away. I need to splice in a new sensor. ^-^

 

[JDT]

My 97 GS doesn't have one.

 

[MiroDSM]

After 96 none came with it
