My car will start and idle fine, but within 10-15 mins of driving my temp.gauge will slowly start rising until it gets to the red light. So i decided to go buy a Hayne's manual for my car and do some troubleshooting. I have then had a buddy of mine who happens to be a mechanic replace my water pump, thermostat and put in a new fan relay switch (?) i think it was.. he said my fans weren't kicking on and after installing that part they did so.. anyways.. after putting those new parts in, the car still overheats, not to mention my heater does not blow any hot air out on full blast. I've asked questions on here in the past and have been told there is air trapped in my cooling system and to open the bleeder valve located at the front of the engine to let it all out until a solid stream of coolant comes out, which i have. Hot air starts blowing out of the heater and i get excited and take it for a ride down the street. the temperature gauge starts going back up and the heater starts blowing cold air again. My friend takes a look under the hood and says he thinks my radiator is clogged up and disconnects the radiator hose that is connected to the coolant tank, puts a water hose in the radiator hose and flushes it out. The car still overheats. He doesn't know what else to do but flush out the block (?) i have no idea what that is. If anyone else has any other suggestions BESIDES getting rid of the car please let me know. I don't see any leaks and im pretty confident my gaskets are not blown since there is no oil in my coolant so... please.. any suggestions would be very much appreciated. Sorry this is so long, just trying to give as much info as possible.

bleeding the cooling system can take a number of repetitions to get all the air out. make sure the car is on level ground. if you have the problem after four or five tries, you could have a warped head that is allowing hot combustion gasses through to the coolant system, or a number of other problems, have the car checked out at a competent shop.
 
Sorry guy but just because there is no oil in the coolant or coolant in the oil does not mean that a head gasket is not blown.take it to a good shop and have them do a compression test on it.Or any thing else they do to check for leaking head gaskets.Hope this helps.
GOOD LUCK
 
heres one 4 ya = if head gaskets do not cure the problem= I had a cracked cylinder wall once in my olds- took a long time to overheat the water / coolant =yet always did it till I sleved the cracked cylinder!! Now cools fine!!
