I didn't see any cracks in the reservoir but im wondering if i just didn’t look carefully enough. Did the liquid test, and it turned out fine. Still confused as to what it is, but I'm going to replace the reservoir and see if that resolves the issue.

I've had an issue with my coolant leaking since about December. Suddenly I had to top my coolant off every week or every few days. Couldn't find any sign it actually leaking out of my car, so I took it to a mechanic to inspect the whole cooling system. He didn't find any issues or leaks, just a hose...

I replaced the battery today, it took a while for the part to come in but I'm still getting the service required message on my dash. Wondering if I could just clear the message.

My alarm is the same one in this video

I got a used part from ebay. Didn't clear any codes

I replaces the siren module, but I'm still getting the message on my dash saying it needs serviced.

This message came up on the dash right after I got my alternator replaced yesterday. Got a new battery in May. Looked on some other forums saying it might be a problem with the battery, but since I had it replaced, I don't think that would be the issue.
