overheating with antifreeze??!
Well every time i change from water to antifreeze the antifreeze overheats my car, today i flushed the engine and put a thermostat in then added antifreeze i put it on ramps and burped the hoses and did this for 10 mins.Steam was coming from the radiator but the car was not overheating ..I drove for 5 mins and it was over heating so i drained it and ran water and now its fine again .Any ideas??

Re: overheating with antifreeze??!
what do you mean "change" from water to antifreeze? if you are running straight antifreeze, then thats why its over heating... it needs to be diluted with water 50/50.... you also shouldnt be running straight water in the summer... not only does antifreeze lower the freeze point of water, it raise the boiling point from 212 to ~250

What temp does it get up to? How long does it take? Does it overheat while stopped then cool off while driving? Make sure the fan is coming on.

Re: overheating with antifreeze??!
I wouldn't waste any more of your time and money changing the fluids back and forth as it sounds like you have a problem with your cooling system in general. Probably the water pump or a plugged radiator to be honest. The steaming from your radiator is probably the water/coolant getting on it from the fluid swaps you're doing and its getting hot and steaming off, that's normal. Worst case scenario could be a head gasket but there are plenty of other things to check before that. If you pop the cap and wait for it to get warm do you see water flowing through the radiator? Good luck

Re: overheating with antifreeze??!
what is the mileage on the motor?
Next time you have a chance check the coolant to see if it is diluted with something else. If it appears milky or has oil in it your HG is done.

og if theres "white smoke" from the exhaust, or if the oil is discolored... actually.. it be on the safe side, do a compression test

i changed my head gasket 2 weeks ago and the car ran good (on water) but antifreeze it steams out of the radiator itself not from liquid hitting anything, anyother thing NO HEAT COMING FROM HEATER WHEN HEATER IS ON?!

Re: overheating with antifreeze??!
When you changed the head gasket did you check for warpage in the head and block? Did you change head studs or reuse? Also, why did you run just straight water instead of 50/50 coolant?

Re: overheating with antifreeze??!
You're right, but some diagnostics is better than no diagnostics.
OP; Have you actually flushed your coolant system ever?
No heat from the heater could be a plugged / goofed up heater core which is causing poor circulation, leading to the rest of your fits.

Re: overheating with antifreeze??!
For one thing, as far as overheating is concerned, it won't matter if you use water or antifreeze except that water will cause your water pump seals to fail prematurely and allow corrosion of the cooling system. Lets also not rule out that its winter and the water could have frozen and cracked the block or head (hence another reason for the use of "antifreeze").
If there was a difference after the water was drained and refilled with antifreeze then it was likely due to improper bleeding of the cooling system.
In this case where it sounds like exhaust gasses could be getting into the cooling system I'd get a block tester kit and use that for diagnosis.
I suspect either the system was not bled properly or the new headgasket is not sealing, for whatever reason.
OP, did you check or resurface either of the mating surfaces?
Why did you change the original headgasket, or rather what caused the original headgasket to fail?
