Does it blow white smoke?/ if so blown coolant seals,

Are you loosing coolant?/if so check hoses,radiator,heater core/ etc etc

How about the thermostat?

Why do you think the rad is clogged?

the keeps on over heating and it seems as if when the car is being driven water isnt being pushed throught he radiator and pressure is causing increased temperature. we think it may be either the radiator or the water pump. could you tell us what the problem is and how to fix, as well as how much it will cost.

Its hard to say whats wrong just by explaining it ,I had a friend years ago,who did everything to his car to fix the overheating problem.. well it had bad seals..

Keep in mind,the more you overheat that engine,the chance your housings,and plates wil get warped..

You might want to start looking towards a rebuild..

the water pump is easy to change,if you do that get the thermostat changed,and rod out the rad if its real bad..

But I still think its the seal..pull out some plugs,are they white on the ends?wet with coolant?do you smell burning coolant with the car ideling?
