Hi, I recently bought this ex-police car. It was checked out great by a mechanic & everything running smoothly other than some squeaky noise from the break & suspension.

It was left idling today (very hot day) with air-conditioner on Max while loading some stuffs so it'll cool for my baby. It probably ran for about 15-20mins (I think I heard a loud "pop" but I wasn't sure) before we drove off. Then I notice the air-con wasn't cool (on max) & kept adjusting it. After about 10-15mins of driving, I noticed the "Check Engine" light was On, also then that I saw the Temperature was on HIGHT.

We immediately stopped by the closest safe location. There was NO leak nor other noticeable signs of low coolant level. After about an hour, the temperature was lower. It started ok, although the engine light was still ON and we also heard some clicking sound from the engine that I didn't hear before today.

Since I've to wait till Monday to get it to a shop, I thought maybe I could ask around what could be the problems and also a guesstimate of costs associated with the repair.

First thing you need to do is have the codes read, Autozone does it free, Post the results with the code number(s). Even if the service engine light is not on, there should be freeze frame data stored.
If it won't make it to Autozone, buy a cheap scanner, they can be had for 30-40 dollars, a good investment, since they cover all cars sold in the USA from 96 on.
If the light is blinking, it means possible damage to the converter. Service it right away!
