Hi, could you tell me where the coolant temp sensor is located on my car please. I changed thermostat and put new coolant in but car is still running cold and using more fuel than it should. Thank you.

Would you know the product code of the engine coolant temperature sensor for the my car? 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.

I cannot 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.

My car (4 cyl 96 honda accord ex) stalled when I pressed on the clutch at normal op temp, run normal when cold though. What I have done to it: cleaned throttle body parts, replaced egr valve, ignition coil, crank pulley, coolant temp sensor, spark plugs and wires. The car had no CEL, can't find any vacuum leak, and clutch still okay. I might change the distributor cap and crank ps (no code on it though). I also found the bottom chain cover was cut by the belt when replacing the crank pulley. Any advices on what I should do next?

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? I noticed a decrease in engine power as well as increase in fuel consumption. Thank you for the help. what tool will I need to replace it? Thanks again.

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

The fact that it stalls is an idle issue.

What is the fuel pressure?

There is an idle control motor on the throttle body that could be an issue.

51 psi and I've cleaned and re-adjusted idle valve and the fast idle valve. Car only has the problem when warm up. Shouldn't idle problem be at all temps? Should I replace the idle control motor?

You are great and very helpful. Can we have the fan relay and the power window relay interchange? They have the same twelve volt amperage.

Cannot clean and adjust the idle control valve. It is computer controlled.

Yes, my guess would be the idle control valve.
