overheating in stop and go traffic and during idling

Good work testing the temperature sensor. I would go ahead and change that sensor and the thermostat as well. That should definitely solve your problem.

Okay, I will do that and share the update. Thank you.

I changed the sensor today. Then I top off the coolant and was making sure by checking for the bubbles... I kinda see bubbles like 3 or 4 at a times and don't see them for a while and see them again( it was raining slightly assuming it's rain causing it bubble - correct me if I am wrong and educate me if it's head gasket related issue ) after I changed the sensor and ran car in the first engine was creeping hot my fans kick on for a while still engines over heating so I shut it off I ran the car again then it creeped little over operating temps and come down again then it never creeped up again til now . Need explaination why it creeped hot in the case if you can please!!. Other than that everything seems fine now but I will be checking it for a week before I igonre it. Thanks for your help

It didn't work after running it for an it's over heating again

I think it's time to check for a blown head gasket. Here's a guide on how to check it: https://www.2carpros.com/articles/head-gasket-blown-test

In particular, the check for exhaust gases is (in my opinion) the most important test. Do that and get back to us.

I replaced thermostat even the old one still looks good. Flushed the coolant. Yesterday it seemed fine that fan were turning on automatically and shutting off. But this morning its was foggy snowing and while I was car indicator creeping up since I have an obd scanner I checked the coolant temp it was about 195 F I pulled over checked for fans. There were dead and not coming on. indicator reached all the up obd sensor reading 195 F. Is 195 F is the ultimate temp or my sensor bad again because its a new one

Hello,

It sounds to me like you have an intermittent fan issue which can be caused by the radiator fan motor or relay. Here is a guide that that will help us do some testing.

Please let us know what happens.

195 is about what your car should be running at. The fans will come on and go off as needed to keep it in that area. To test, I'd turn the A/C on full blast and watch under the hood while it idles. You should see the fans come and go. Unless I'm missing something.

My fans for coming on at 207 -209 range and not before that. And at 207 temp guage creeping high or very close to red but not on red.

It sure sounds like a blown head gasket did you do the test Heyman suggested?

Your car has three different fan speeds possible. There is a separate relay for each one. The PCM activates each speed at different coolant temperatures. They're all in the underhood power center/fuse box. You can swap them out and see if the behavior changes. If it does then just replace them. They appear to be pretty standard relays that should be available at AutoZone for a decent price.

Sorry it took me so long to get back to you. I thought I had said this yesterday. I must not have clicked "Reply."

No I didnot do block test for observed for bubbles in the radiator, checked for oil in the coolant and checked engine oil for any sweet smell and for thickness or white substance

I am assuming 207 is not ultimate temp for guage and this wont happen all the time. For example if I drive for an hour and stop and idle with blower on high the guage creeps up high but obd scanner stay ay 207 or 205 and it comes down slowly when I trun off the blower

Again I say, check the relays. The low speed one should be kicking on well before 207.
