Hey, all i did my radiator flush this afternoon, but i am not sure how much to mix in. I do not have an owners manual so i dont know how big the radiator? 8qt? 10qt? I just guessed and as a result didnt mix in the proper ammount of coolant with water so now my motor is running hotter then it normally should. If anyone could supply me with that information that would be great, since i want to do it 2 morrow and get my car up and running to its normal temp

 

its 50/50 ,make u use the silica free coolant(orange stuff)dexcool.it will protect your engine better.how hot is it running?improper mixture shouldnt cause it to run hotter unless the radiator isnt full.also make sure you bleed the air out of the system after u fill it,this could be your problem

 

bleed air? The car usaully runs between 110-130* when at idle and moveing also it is 50* out. After i did the flush the car has been running hot, 160+. It did hit 210. I do realize that it should be 50/50 but i do not know how much to put in since i do not know the size of the radiator. and yes it is the orange stuff, it is the coolant recomended by GM
