I keep putting water in my vaxhall astra as it overheats, if it is the head gasket how much will it cost to be repaired.
Only until it overheats.
Have you had the rad. checked ?
it is probably your water pump
check the water level, if its okay then you probably need a thermostat
Change your thermostat.
it gets dehydrated and probably overheats
first check to make sure your fan comes on. if it does then there are several things that could be wrong. first do you have enough water/antifreeze in the radiatior. check to make sure you have no leaks. then replace the thermostat located in the top radiator belt housing connected to the motor. if it still overheats try replacing the water pump. if it still overheats after that check your oil to see if theres water in it if there is you blew a head gasket
At a guess, bearing on its way out
check your fan clutch if its weak it will overheat
Generally when it leaks fluid or possibly if it overheats and the thermostat is OK.
The water pump for an s-10 engine is located on the front of the motor. The engine can be damages if it overheats due to a bad pump.
Be sure the thermostat is not installed backwards.
