My coolant is leaking from my car .....overnight the level drops considerably no sign of wetness on driveway. I am having to continually top up ...the car has recently had the pipe repaired coming from the coolant department ...any ideas or is there anything I can use to self seal ???
You will probably find that the coolant is leaking out whilst you are driving your car, I would suggest that you run your car up to normal working temperature and then check for leaks. Radiator sealers are very good but not the ideal solution and they only fix holes in radiators, not leaking pipes etc. If you cant find the leak yourself, take your car to a reputable garage where they can pressurize the system to check for leaks.
