Car overheats even with new water pump, thermostat, coolant and both hoses, what else is left?

car overheated so i changed the waterpump, thermostat, coolant, upper and lower hoses. car still overheats after only 10 miles of driving. upper and lower hoses are both hot(roughly same temp as engine, will burn you). heater does not blow hot air. thought may be head gasket, but no oil in coolant, the oil is of the same consistancy before overheating problem(black as night) and no white smoke from exhaust. dont know what else could be a problem. radiator cap wasnt changed, but i dont think it would cause to overheat that quickly. please help

It is highly likely that you installed the thermostat in backwards if your heater does not blow hot air. That or your heater core is clogged and preventing water from circulating.



I would try this.



Remove the thermostat completely from the car.

Try driving it for the 10 minutes and see if the car overheats. See if your heater now works. If it doesn't overheat and your heater is blowing warm air you had the thermostat installed backward!



If it still overheats and your heater is still blowing cold, you've got a clog some where. Most likely in or around the heater core.



From firewall disconnect hoses going into heater core and connect them together to by pass the heater core.



Now see if the engine still overheats. If not the clog is in the core.



Other things you didn't mention. Do the fans turn on?



E-mail me if you have further problems.

if its not blowing out hot air could be a blokege our the pump might be ******
It would help if you gave the car model and year. Guesswork is that you have a fan with a thermocoupling, not an electric fan and the clutch is no good so that it never spins fast enough but the other fact that you get no heat at all and you over heat very quickly points to a clogged cooling system. Have your cooling system power cleaned and don't be surprised if you develop some leaks.
You might have a clutch fan that is not working or an electrical fan that is broken.
radiater could be clogged
If you do not have hot air coming out of the vents it probably means you are not getting coolant to the heater core. Either there is a blockage before the heater core or a leak. This may also happen if the thermostat is put in backwards or if its the wrong temperature thermostat.
Make sure you don,t have a hose collapsing which a lot of time Only happen,s at higher RPM,s
I had the same problem. Is your fan running? If it only it is or if it only runs when your a/c is on it you might have a raidiator problem.
First start off by removing the thermostat, and running the car that way. You can check the operation of the thermostat by putting it in a pot of boiling water to make sure it opens up. If your car is running cool without a thermostat then that is your problem. You can also check to see that you have proper flow by disconnecting the top hose on your radiator and starting the car, there should be a flow of fluid after the car warms up to operating temp. If no flow then you have a bum pump. Also check to make sure that the belt is going in the correct direction on the pump. I hope this helps.
still could be a head gasket you could purchase a combustion leak detecter. This tool would tell you definitly if it is a head gasket or not. Uview makes this tool. part number 560000
