Default Help!!!!! Need Guidance/advice Asap

So my cel has been on and the code is for the thermostat. My car was running really cold, specially when i'm on the highway. Sometimes it stayed at 0. So finally got a Stant thermostat and decided to change it today.

when i took the old one out IT WAS BROKEN IN HALF. The spring valve was missing. Not sure if it was cut out. Can this brake of like this? This is the first time i see this.

Inspect the old piece very closely. Does it look cut? I can't imagine a thermostat failing like that with no repercussions. For one thing, the impeller is right there, the missing pieces would get caught up in there. If you can, look inside the water pump for any visual indications of coming into contact with the spring. If there are no scratches or gouges, then I'd say the missing piece was cut out. Is it a used car? I wonder if the PO did that in response to overheating.

New water pumps aren't super pricey and a good option if it's also about time for a timing belt (100k). However, I assume the car needs to run right now. I would say just toss the new one on and drive the car. I too find it very odd that a thermostat could break like that. Like was said, it was more likely cut. As was said already, you can certainly inspect the water pump too if you feel like taking off the timing belt (not really hard to do). The only problem you may have is that the old timing belt may have its timing marks worn off, so you may need to remark locations again before removing.

Ok great thanks guys...I am planning on changing the timing belt as my car has 145k....if it didn't get cut and it broke off it wouldn't pass the water pump correct? I did know someone who cut it due to over heating...and yes this was a used car.
