WHERE IS THE COOLANT TEMPERATURE SENSOR 1

Engine Performance problem

My car has the sympstoms of a bad coolant sensor and I would like to replace it myself but can't figure out where exactly it is located. A photo will help. Thanks!

Would you know the product code of the Engine Coolant Temperature Sensor for the 1997 Honda Accord SE at Advanceautoparts? I bought the ECT sensor with a product code WT5009 and it is not the same fit. They asked me if this is for the computer system or the cooling system.

Can't find that code. The ECT sensor at Advance Auto Parts that I bought has a code of WT5009 which does not fit and the other one that I searched online was WT680.

Those are the different companies part numbers they use for their systems, the actual OEM Honda part number is what I listed last post.

Please see encircled item on the photo. Is that what I need to replace when my radiator fan is still on even after the engine is off and I noticed a decrease in engine power as well as increase in fuel consumption? Thank you for the help and what tool will I need to replace it? Thanks again.

No, faulty radiator fan relay would be the cause of that issue.

Do you have a photo where it is? Is it the same as the radiator fan switch?
