I’m trying to locate the outside temperature sensor on my ’98 SE. Last week I had disconnected the battery in an attempt to determine if my overflow bottle had a crack in it, (I’m loosing coolant) and when I reinstalled the battery the heat did not work.

I read some threads on the forum which suggested that I disconnect the outside temperature sensor, start the car and then re-connect it in an effort to reset the ECC.

I know it is supposed to be by the radiator………could anyone chime in as to where it is exactly (bottom, middle, top)…….a pic would be even better if anyone has one.

Thanks in advance.

I believe it is in the middle of the car in front of the radiator. If you open the hood and look down in front between the radiator and the bumper you should see it sticking out. If you need a picture of it I will take one for you when I get home.

EDIT:
Here'* a picture of the sensor, circled in red.

It will the only thing sticking out in front of the radiator behind the grill

Jay...

The ECC is in a "re-learn", it can easily take it a couple dozen cold starts to get the air door to find the right position for operating. That fix you are talking about is for when the car is heating just fine, but for some reason the temp light still goes into the blinking mode. See what happens, but we may have to do the wrench through the glove box to get the door right. That'll mean you have a crack is the plastic gear for the actuator arm. While you are still trying to see if the ECC will learn, be sure your selected temperature is over 80, but NOT equal to 90. It''ll make the process go faster.

The important question... are you losing coolant onto the engine or ground, or is it just disappearing?

Here is an update.

First, thanks to Anathema05 for the pic and fast response.

Charlie, after more diagnosis, the leak was coming from the water pump (original). So we replaced the water pump, the upper/lower radiatior hoses and the thermostat. All were original parts......12 years old.

We made a trip to the Finger Lakes in New York State on Sunday, 650 mile round trip. Coolant level was fine, and the car performed well with 28.6 MPG on the trip.

I'm still having trouble with the blinking display on the ECC and erratic temp fluctuations, and hope to take the glove box liner off today for a look. Updates in a few days I hope.
