so my last post, Question: where can I find someone to replace my thermostat? now today i went to a shop to have them put in a new thermostat. $180.00 last week i went there and they did a full comp scan and the only code they got back was for the thermostat.
when the mechanic took it off he showed it to me. the top half with the spring was missing. the base was all that was left in the car. so now i am really upset because the dealer told me my thermostat was still good. so the mechanic let it run for about 15 minutes then took it on a 10 mile drive on the express way. everything checked out fine.
so now what? i drive about 10 minutes, to the chrysler dealer to show him what was left of the thermostat. because they had refused to replace it.
now just as i turn in the lot the service engine light goes on. so i talked to the service manager about the whole situtation. and it was like this from day one since i bought the sebring. when i bought it, from a used car dealer, i asked about the service engine light and they said it was that there is a bubble in the fuel line.
anyhow i then showed the chrysler service manager what was left of the thermostat. he said the mechanic broke it off! i told him i was right there when he removed it! then he said sometimes they will just break. i asked him where will the rest of it be then? he said it will drop in the engine...... ????????????????????? hey, that doesn't sound good.
so he has one of his mechanics run a diagnostics. ok,so now they say its my catalitic converter issue!!!
idk they also insist that the waterpump is bad.
the sebring came from florida. why would they break off the top of the thermostat and and leave the base attached? could it have broken off and went in the engine somewhere?

By breaking the thermostat on purpose it would allow the vehcile to run cooler. The therostat opens at a certain temp usually around 95-115 deg. depending on the vehicle. If it broke while installed in the cooling system the debris or parts would be in the cooling system and may have worked there way to the waterpump and damaged it. Just a possibility. The parts are not inside the engine as I think you may have been mislead. The cooling system and engine oil are seperate and at no time or in any motor will mix. There are times where they do mix but thats a totally diffrent mechanical problem you will not experience due to your concern.

ok as my last post about the computer scan. please re read my post. last night i was driving into my driveway and felt the ice and solid snow scraping the bottom of my car. so i didn't continue into the drive and parked it in the street. it took me about an hour to dig out solid iced and heavy icy snow so i could pull my car in the driveway. Could i have damaged something under the vehicle that would throw up a emissions code? catalitic converter P0430 bank 2. One mechanic said I could have put in some bad gas.
Ok, about the thermostat, I am baffeled about where the top half could have gone. I have driven this car about 10,000 miles since I bought it. The thermostat never worked since I owned it. If it had broke off and went into the cooling system, wouldn't I have had problems with the cooling system before or by now? What symptoms would I have had with the cooling system?
