First of all you can't get an estimate until you know the problem. Is there coolant on the ground? Is there coolant inside the car? Open the hood and check your oil for foaming ... looks emulsified..Look inside the radiator .. does the coolant look clean after the engine is started? and finally .... turn your defrosters on ,,, is there a residue on the windshield?

Radiator flush is good. . . If you remove your thermostat and it has gross corrosion then your radiator more than likely looks the same. Clogged engine block means insufficient cooling capabilities and you can crack your block. A loose radiator hose will cause leakage and inconsistent pressure in the cooling system and will cause your vehicle to overheat and cause head gasket problems. Make sure your thermostat was replaced properly otherwise it will not work. . If your radiator has been previously topped off with water and caused rust . . . Purchasing a new radiator may be last resort . . . But check the heater core like tom suggested.

One last thing they say it doesn't matter any more but different coolants and brands and types should not be mixed will cause chemical interactions play it safe.

Thank you. I will keep you all informed as to what's going on. Also any idea how much it cost to repair heater core? I no dealer parts is only roughly 130 but labor I'm guessing is ridiculous since it is in dash

Your problem could be as simple as a bad radiator cap or cap not properly on. It would cause everything you listed even the 0300 misfire when coolant gets on and it plug wires

Cars now at shop just waiting for them to call and let us know why it's overheating and why coolant isn't staying in. We already replace cap, thermostat, water housing etc. So now just a waiting game.... too be continued!
