Overheating runs hot after about 30 mins and it has cooliant

The fan or fans that cool the engine are not turned on until the engine coolant reaches about 225-230F, so they may not run for a long time, if it is not overheating why are you concerned.

overheating safetybsprings are wore out. they either got over heated or reached their limits

you have wasted money on fixing what has not consequence on the oproblem
overheating is from 4 things
1--- no/insufficient water in the cooling system--air lock in system- fill radiator to cap level and bleed air out
2--blocked radiator cores -- have a radiator shop do a flow test
3-- fan not working--no power from relay, ECM. coolant temp sensor , fuses-- have an auto electrician check the circuit
4--- blown head gasket /cracked head-- have a compression test done

Is the back of the T.V. unusually warm/hot? If it is your T.V. may be overheating. If it's not in an open area, move it to an open area to allow more air flow. If it is try directing a fan at it. If one of those helps then your T.V. might be overheating and you may need to replace the cooling fan in it.

bad water pump or air in system??? look for bleeder screws

it's overheating... maybe your heatsinks aren't making contact... they should be quite warm after 30 seconds of the console being on.

it is overheating. first thing to try is ****** the timing, to run cooler, as you have just replaced the points.-plz rate -bozcro

cooliant sensor is bad ,you have two,one for cooliant temp and one for cooling fan both are in therostate housing or in some of the cooliant ports,

How many times has it got hot? You better do a cooling system pressure test. Sounds to me you got more problems than a cloged radiator. Do you see a puddle under the car? Its got to be going someware. Do the test.

The use in modern engines is not recommended because of the high temperatures encountered by the coolant. Etylene glycol or other antifreeze products also raise the boiling point of the water, to better avoid overheating. you will get it in professional garage shops or car repair shops but taske care you do not use water only object in plase of cooland if they suggest as it will damage the part.
