my coolant reservoir was empty ,and I thought i was hearing knocking from the engine ,so I took the car to firestone and , told them the symptoms , they suggested a perssure check , dun know what that means , so after the diagnosis was done , they came up with the following results ,
1) the sytem pressure was 20 Psi
2) no leaks found
3) temp guage below half
4) oil dipstick has dark brown color
5) no white smoke on the engine start
6) heard no knocks in the engine.
7) they found moisture on the oil cap
the firestone people did not know how to deal with this ?
so they toped off the coolant in the reservoir and the radiator
but told me to keep an eye on the level in the reservoir. now what I am afraid is if there is a leak internally ,its going to damage the engine ,so i dont know what to do ?
how can a coolant resevoir be empty if they found no leaks
my car is at 137 k and ran fine until i thought i heard knocking sound , but i guess it isnt knocking but stallin
