really !? get your money back and find a new school :scowl:
Then find the leak. hoses, head gaskets....etc. It's a closed system and you shouldn't need to refill it.
But there are no leaks / puddles in my parking spot.
so where is the coolant going then ? C'mon this isn't rocket science. You're losing coolant, where is it going ? You're either leaking it or burning it. Which is it then ? If you're burning it, you've got big problems. Has the car ever overheated, even just once ? I'm thinking blown head gasket or a cracked head now.
Take a look at the coolant header tank level, see if it has dropped again. Could be an air-lock, leaking rad, look for dried chemical deposits (dried antifreeze) on the radiator/hoses.
Checking those fluid levels (everything you can) every month is well worth doing.
It's going somewhere--I hope somewhere external and not into the oil or combustion chambers.
A small leak or a weak coolant cap can dribble coolant--as vapor, or liquid that evaporates on the hot engine surfaces--and not leave any telltale drips or puddles under the car. They can be difficult to trace down, but not impossible.
The car runs fine. Hoses seem fine. I'll give it another look over, check the rad again etc.
One thing I've learned thru this process is I have to spend more time looking after my car.
I think if the head gasket has gone or the block has cracked, the car will start boiling up with-in 30 mins of use. You can unscrew the oil filler cap, if it has a pale (cream) colored residue on the bottom, the gasket has gone or is on its way out. Check if there is any oil mixed in with the coolant in the header tank too, another sign.
Often to find an external leak you have to clean and degrease the engine first. They're easier to spot on clean surfaces.
To find an internal leak, look at the color and consistency of the oil (on the dipstick, for example) or any goo on the underside of the oil filler cap. A chocolate milkshake-like froth could indicate the coolant's leaking into the crankcase. An unusual amount of white smoke in the exhaust means it's leaking into one or more cylinders.
PO118 means the coolant temperature sensor is operating outside it's normal range. If you have access to a scanner, look at freeze frame data (the PCM takes a snapshot of data when a fault occurs) to see what the sensor was reading when the light turned on. The problem could be the sensor itself, the PCM or the wiring between the sensor and PCM.
Agreed with everyone that says the coolant loss issue needs to be addressed. Have someone pressure test not only the system itself but also the radiator cap.
Might be the cap.... or... THERE IS A KILLER AFTER YOU!!!!
Helpful. Thank you.
A blown head gasket or cracked block will overheat a car real quick.
I am so curious to see what this is...
