Still overheating

Don't ya just hate it when your car runs hot? Pressure test the cooling system. Then I'd replace everything that's cheap and easy first and make sure the timing is spot on. Six year old hoses gotta go. Thermostats are cheap. Soun ds like the one in there is faulty. Use the right one for the car as prescribed by the manufacturer, don't go to a 180 just because you think it's gonna make the car run cooler. That's not gonna address the real problem. The coolant (not water) has to stay in the motor long enough to transfer heat and the engine will run better at a certain( sometimes higher but usually around 195-200 degrees). Pull the plugs just to take a look see- maybe signs of water or indications of a lean condition or timing problem. That stuffs cheap and easy. If all is well then look into bigger stuff like radiator flow, water pump ( new pump is cheap too, actually). Every car should have a shroud whether the factory put one on or not. You don't see anything without one after about 1970 because they are cheap and make alot of difference in pulling air through the rad (especially in slow, trafficky driving in hot weather) Oh yeah, almost forgot, no water with minerals (tap water) use 50/50 anti-freeze or distilled water. The minerals ( iron and what-not) decrease the boiling temp and increase clogging and gook. On your carb idle mixture, use a vacuum guage to achieve max vacuum while messing with the screws. Check that tee to make sure it's not clogging up. On the subject of air pockets, they're getting in there because it's getting too hot and steam is forming. That's gonna cause more heat and more steam and more air pockets. Gotta get the air out and figure out what started the whole vicous cycle.I look at it like this, I'll gladly spend a few dollars ($50-$200 or whatever) to cherry out the cooling system so I don't have to spend alot later! Good Luck!
