While the engine is cold, take off coolant cap. then fill the coolant tank to proper level, start car ,let it idle when thermostat opens then you will see air bubbles in tank. wait till they clear up then replace cap. you can feel to see if it is heating good, by feeling the top radiator hose. if above gives you a problem you can squeeze top hose a few times by hand with cap off. this will remove any air that is left in system. try above first. have a good one!!

    i know on some vehicles its a big pain, i had the same problem on a jeep cherokee last year. and it took about an hour to get air out of system. try this, refill cooling system, and raise right front corner of car with a suitable jack. set heater to max, and leave the fan off. with radiator cap off start the engine. when engine reaches normal operating tempuature, open the air bleed screw until coolant flows in a steady stream. lower the car, fill the coolant reservoir. close the cooling system and verify if it works! thats all i can say. sorry for the first info, but that usually works. but the procedures are different on all cars. good-luck!! not all cars have bleeder valves. look for bleeder anywhere in cooling system. if no bleeder, then follow above, but leave bleeder out.

My engine temperature fluctuates from normal to overtemp. I fitted a new thermostat and it ran perfectly initially then stareted fluctuating again sfter about 10 kms. What is wrong?

I agree that it is probably due to a bad headgasket. Combustion gases leaking into the water jackets of the engine cause overheating. The easiest thing to do is top up antifreeze and have the rad cap off, bubbles should eventually stop coming out if it is only air stuck in the system. If it continues..... you have a bad headgasket. At times the air bubble coming out of the rad/reservoir will even smell of exhaust fumes. Good luck!

Put new radiator in,and no heat comes out,Could my hearter core be froze up.

You might consider bleeding out the air you might have in your cooling system after you opened it,drain it to replace radiator.Let it cool down open rad cap start engine watch the burps of air come up when air locks are out coolant starts to swirl as it circulates might drop fluid level to have coolant on hand to top up after wards shut it of with rad cap off let it sit for as long as you possibly can any remaining air locks will burp out.Once coolant completely down put your rad cap back be sure fluid is full reservoir as well.Now see if you have heat.

Replace ther fan rad water pump even put elec fan on still heating up

Have you replaced the rad cap or the thermos stat? If so you may have an air lock within the system which would require you to run the car for 10 to 15 mins with out the rad cap on this should remove the air lock..

I am hearing what sounds like running water when I accelerate since I installed a new radiator. Could this be associated with the radiator?

yes, you probably have some air trapped in the system. if you are getting good heat in the car and it is not overheating, there is no problem. if you want to bleed the air, idle the car with the rad cap off (put a bucket underneath the car, some coolant will spill out). turn the temp knob all the way hot and turn the heater fan off. as air in the system bleeds out, you will see bubbles coming out the rad. usually takes around 15 minutes. if it is a stubborn air lock, try revving the engine up and down a bit while you are doing this.

Vehicle needs to purge all the air form the radiator. Jeep Grand

Start vehicle when cold. remove rad cap, start engine & put heater on (not defrost) and let it run for a while & top up rad as coolant goes down, to about an inch or 2 from top of rad. If you have electric rad fans, watch temperature gauge and around normal operating temperature or slightly above, they should come on for a minute or 2 then shut off. If not electric fans, just watch in top of rad for increased flow through rad, indicating thermostat has opened & coolant is circulating. Rev engine slightly every once in a while for 5 or 10 seconds just to help increase flow etc to help assist bleeding air out faster. Watch for increased flow in rad, 2 or 3 times at least, or listen for fan to go on & off 2 or 3 times before putting rad cap back on. As your doing this, keep topping up rad if it needs it. Make sure rad cap on all the way, check coolant return bottle level & add to mark if required, and you should be good to go. One of the things people forget to do the most, is to turn heater on while doing this, and that is usually what causes a lot of airlocks in the system, so don't forget that step.

No heat on a 1994 4 cyl. Dodge Caravan

Pretty common on those. I used CLR and disconnected my heater hoses & with a small pump, I ran CLR only, through the heater core, and let it sit in there overnight, flushed it through again next day, back flush as well. re-connect hoses, run engine with heater on, and rad cap off until the rad fan comes on 2 or 3 times, then put cap back on, to bleed air out of system. Cleaned it out enough to get the heat flowing again. If you changed thermostat and didn't let it run with heat on, and rad cap off for a while as described above, then do that first, just to make sure you haven't just got an air lock in the system.
