In the general case, cars overheat because of a bad thermostat, low coolant level, blockage in the coolant system, insufficient antifreeze percentage, fan blockage, or water pump failure.
In the general case, cars overheat because of a bad thermostat, low coolant level, blockage in the coolant system, insufficient antifreeze percentage, fan blockage, or water pump failure.
Could be a number of reasons. Insufficient engine coolant, old and burned out engine coolant, improper heat exchange from the coolant to the ambient air in the radiator (this could be due to blockage in the radiator, insufficient pressure in the cooling system, bent fins in the radiator, etc.), bad water pump, blockage in the cooling system, improper coolant.... take your pick.
If there is a blockage of the ventricular system the flow of CSF is interrupted
The water pump is what circulates the coolant through the system. Make sure the system has enough coolant first. As for the heat issue it could be a blockage in your heater core. This would cause the hot coolant not to circulate. You could also have a blockage in your radiator and\or a bad thermostat, but these should eventually cause the vehicle to overheat. Hope this helps you some.
Low coolant, bad coolant, blockage in the coolant line, bad heater core or element, bad thermostat
In general, cars overheat because 1.) there is not enough coolant, 2.) there is not enough anti-freeze, 3.) there is not enough coolant flow, either due to blockage, a bad water pump, or an air bubble in the system, 4.) there is not enough air flow, either due to blockage or a bad radiator fan, and/or 5.) the thermostat is defective or stuck.
If your car is overheating, then a condition exists which needs to be diagnosed and corrected or repaired. It could be bad coolant, poor coolant flow, blockage of air through radiator fins, bad thermostat, or a number of other things.
I don't think that this problem is unique for a vehicle of it's age. You probably either have some blockage in the heater core or your coolant system has a bad thermostat or the coolant system has a significant air pocket (that needs to be bled out.) The cheapest thing is to try and bleed the system, then replace the thermostat, then flush the coolant system. In a rarer situation you may have a vacuum leak that effects the valve controlling the circulation of water into the heater core. None of these are expensive but are time consuming.
sounds like blockage in the cooling system. See if you are not low on coolant in the radiator. Just because your reserve tank has coo;ant does not mean that you have enough coolant in the radiator. If you have low coolant in the radiator, it will blow cold. It can happen abruptly. If you are low on coolant in the radiator and not in your reserve tank you will need to find out why the system is not pulling coolant out of the reserve tank.
Trasnfat is
What ff14 means is that there is a fault with the coolant temperature sensor. This could mean a blockage in the system (radiator, thermostat, water pump, etc), the temperature switch, or a loose connection.
