Symptoms Of A Blown Head Gasket
Often the first initial thing we see is a climbing temperature gauge, or a warning light on the dashboard. You should pull over at this point to make sure a radiator or coolant hose hasn’t blown or a fanbelt has broken and no longer powering the fan. Check to see if you in fact have enough coolant, if no routine maintenance has been carried out there just may not be enough to perform its role.
Have you been constantly been adding coolant?
Has the car been losing power?
There are a number of checks a mechanic can do as he has more tools like C02 testers, die testers and cooling system tester pumps.
Check the radiator to see if the water is bubbling. If it is, there is air getting into the system which is a classic symptom.
If there are no bubbles at the end of driving for the day when the engine is warm leave for the night then take out the spark plugs in the morning when everything is cold and check to see if any plugs are wet, emulsified or coloured (from burning coloured coolant).
Or finally, look for coolant stains around the engine compartment when coolant could have escaped externally and the water content has evaporated.
Remember, to continue driving an overheated car may not just blow a head gasket but could seize the engine completely.
