Suzuki swift 2005 1,3 petrol overheated .coolant fluid was boiling but didn't seem to leak .started the car again drove a couple of miles and the same again.


check to see if the cooling fans at the rad are working. if so then change the thermostat and refill the system. if not then have the head gasket checked for cracking. make sure the coolant is circulating if its not it could be a plugged cooling system or even a water pump impeller problem.

How to tell if radiator is not working on 2004 Grand Prix changed everything else


If rad is plugged/restricted the vehicle will overheat. If thermostat is opening, both upper and lower rad hoses will get hot. If there is a rad problem with circulation, the upper hose will get hot and the lower hose will be cool/warm

Changed thermostat and added coolant but 1997


could be waterpump?
i was going to say rad fan,but if so heater would be hot.
lack of coolant will make heater core to blow cold,if engine heats up with full coolant,usually means poor or no circulation.
water pump?
run engine with full coolant,at operating temp.with rad cap off and look in rad cap hole and see if there is movement of water inside rad.
[rad fan will not come on if water is not circulating through rad water pump?]

not likely it is more than likely the waterpump, make sure the thermostat was not put in upside down. if fan is not kicking on it is a fuse or coolant switch for the fan

1994 Honda Civic LX\overheating within 2 mile drive


Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

Overheating


I think you need to do a cheap and extremely accurate test.Its called a tk head test and it determines wether you have head or head gasket problem.If you could eliminate that part as being the cause then that really only leaves a couple of things left to check.A blocked radiator or an air lock.Maybe a faulty radiator/expansion tank cap not able to maintain correct pressure

2002 V.W. Jetta 2.0 liter overheat


turn your heater on to max heat and high fan. then see if you can feel the hoses on the firewall for heat they should be hot. make sure that the fan unit on the radiatoris working if the upper radiator hose is hot the fans should be running if they are not that means that either the relay is bad the thermo sensor is bad or the fan unit is shot... please rate the solution..........thanks
