    I need to known if my radiator is clogged.
    I replaced the thermostat and waterpump. The truck is overheating and blowing cold air instead of heat. I had heat before I changed the waterpump.

      Loss of coolant because of a coolant leak is probably the most common cause of engine overheating. Possible leak points include hoses, the radiator, heater core, water pump, thermostat housing, head gasket, freeze plugs, automatic transmission oil cooler, cylinder head(s) and block.

      Make a careful visual inspection of the entire cooling system, and then PRESSURE TEST the cooling system and radiator cap. A pressure test will reveal internal leaks such as seepage past the head gasket as well as cracks in the head or block. A good system should hold 12 to 15 psi for 15 minutes or more with no loss in pressure. If it leaks pressure, there is an internal coolant leak (most likely a bad head gasket but possibly also a cracked cylinder or engine block).

      It is important to pressure test the radiator cap, too, because a weak cap (or one with too low a pressure rating.

      1. Perform a cooling system / radiator pressure test when the engine is cold - as a first step to locate the leak.
      Obtain a loaner tool / free radiator pressure tester from the local auto parts stores such as Autozone, O'Reilly, NAPA, Advance Auto, or PepBoys. Follow their instructions and pump it to an adequate air pressure 12 -15 psi or the pressure rating listed on the radiator or reservoir cap. Observe the leaks and perform the repair.
      Note: do not over pressurize beyond the pressure allowed by the radiator cap, then test the radiator cap as well.

      2. Air pockets trapped in the cooling system can cause the engine to overheat. Some cooling systems have air bleed valves built into the system to aid in the removal of air pockets. Advice: For many cooling systems, the method of removing air pockets is to start the engine and allow it to run with the radiator cap off or loose until all the air escapes from the neck of the radiator. For some systems this method is not sufficient, and the manufacturer has installed air bleed valves usually near or on the thermostat housing.

    It acts like its not getting a steady stream of gas when I push the gas pedal.
    Sounds like it's bogging down surges when giving it gas to excellarate.

      There should not be any ice in your reservoir. Should be 50/50 mix dexcool orange coolant. Obvious there is not a good coolant system protection level. Sounds like you are burning coolant if you have that much white smoke. Usually you can smell it. So headgaskets are more than likely the cause. The ringing bell sounds like a check gauge or warning message issue. Is low coolant light on.

      no coolant light on car was fine till last night.. smell a burning smell out of heater and turn engine off right away. should i put coolant in, the bell sounds are different sounds all at once.. still very cold here Colorado thought I should wait to try and start car?

      If you know reservoir is froze I would add some straight coolant to strengthen concentration.

    Maybe a case of bad gas??
    I filled my car up and later that night it seemed like I heard a very light knocking sound but the car was still running fine. 2 days later my car started to stall and out of nowhere it wouldn't move when I pressed the gas. I was told I probably had gotten bad gas ...

      That white smoke could be coolant

      Better stop using it immediately

      Could be a failed head gasket
