1986 cooling / overheating problem
I have just replaced the water pump and thermostat because the water pump was leaking and was experiencing overheating. after 2 days, i still have a cooling/over heating problem. I have added alot of coolant and it is going somewhere. I have checked the oil and it is o.k. out the exhaust pipes the is alot of steam and condensation. Need some insite. head gasket ? seal ?

So, your car is overheating and you are loosing coolant?
How hot does the engine get?
What temperature do you consider overheating?
Any signs of coolant under the car or puddles on top of the intake manifold?
Did you make sure to evacuate the air out of the cooling system and fill the radiator as needed?
With a 180* t-stat, the driving temperature should be around 180* +/- 10* depending on outside temps. The main fan will come on at 227* from the factory. The aux fan (if equipped) will come on around 235*. Overheating, to me, is a temperature over 240* becuase the fans should have decreased the engine temperature by that time. If the engine temps gets to 260* turn the engine off.
You can have the cooling system/radiator pressure tested to confirm a leak. Also, Autozone or other auto parts stores sell a dye kit you can use to detect leaks. Usually white condensation or smoke out of the exhaust points to a head gasket leak.
