When cold starting, almost sounds like opening a fresh 2-liter Coke bottle - Toyota Yaris Forums

I've noticed in the mornings when starting my car, and sometimes after work after sitting in parking lot all day I hear a strange sound when starting my new (used) yaris.

It almost sounds like when you open up a fresh 2-liter real fast. That quick "PsssssT" sound but its loud, like hurt my ears loud when in garage and windows are open. Once it does that quick sound, there's no other sound that is odd.

Is this a loose belt? How do I check proper tension and tighten or loosen if necessary?

I don't know if this is true or not, but I think my car may have been in a flood at some time. Its not on the carfax when I bought it, but when i took off all the dash board panels this weekend to do the Viper 211 install, everything under there had this even coating of dirt over everything. not very thick, but it was thick enough that you could not see the black plastic under it. could this be a problem causing the noise?
