Topping up the oil has very little bearing on engines overheating.
You need to remove the radiator cap and top up the cooling system with anti-freeze and water mixed to specifications. Note that I mention RADIATOR CAP and not the expansion reservoir cap. Remove the radiator cap with the engine COLD. Once you have filled the radiator, you need to run the engine until it gets to full operating temperature. Some of the water will overflow out until the thermostat opens, then the water level will rise and fall. When it has settled, bubbles have stopped, turn the engine off, top up one last time. Replace the radiator cap and then top up the reservoir tank.
There are videos online, Google 'burping cooling system', and look at the images tab. Here you go.
Turn the Key to the 'ON' position, the fuel pump should run for about 1 second. listen for it. Do this a few times without trying to start the car. This should pressurize the system. now try starting the car. There may be air in the system from changing the filter.
first drain the contaminated fluids. replace oil filter and put new oil in crankcase. drive a few days and check for moisture. will be foamy white on dipstick. this could foul the plugs or cause white smoke in the exhaust if you can't see behind the vehicle after a couple days change the oil and dump out the filter. the filter could be rinsed out with some gas.
Hi Manuel, That warning light indicates the coolant level is low. To attend the problem make sure the engine is cold. Open the filer cap and the bleeding nipple. Open the cabin heater control to fully hot and fill until all air bubbles have been evacuated from the cooling system (top up with the required mixture of water and coolant/anti freeze, about 40 percent coolant sixty water) When all bubbles have been evacuated, close the bleed nipple and replace the filler cap. Set the cabin temperature as required. If coolant is at correct level and system has been bled it is possible the sender unit may have become defective. Regards John
white smoke is caused by-- water or anti-freeze entering cylinder . if in radiator or the overflow tank. it will look like a chocolate milk shake. check on oil dipstick for traces of water or anti-freeze. also, a bad head gasket will let water or anti-freeze in combustion area. head gasket symtoms if bad. Symptom #1: Chronic Engine Overheating Symptom #2: Significant Drop in Coolant Level Symptom #3: Mixing of Coolant and Engine Oil Symptom #4: White Smoke from Exhaust Pipe popping of overflow cap Symptom #6: Air Bubbles in Radiator Symptom #7: Engine Lacks Power GOOD-DAY!
Laura, it sould like a valiant effort so far. Have you burped the system? There could be a big air bubble in the heater core that will not allow any anti-freeze to flow through. Never try to pick a car up over the shoulder and attempt to burp it. :) Instead take a 10MM socket on a long extension ratchet and do this: Open the hood and stand right in the middle in front of the engine. Look in and downward to about the first arm of the injector plenum. That's the big, flat black piece of plastic on the engine with six arms sticking out to the left and right side on top of your engine. Look carefully downward and look for a little nipple sticking out just to the right of center on the top-front on that area. As a guide, follow the top hose from the radiator to the aluminum manifold. Look carefully and you can see it looking back at you. Stick the 10MM socket onto it and turn it COUNTER CLOCKWISE to break it loose. Once loose, either air, or anti-freeze or air AND anti-freeze will come out. To avoid a mess plug in a 1/4" clear hose to it and stick the hose into a bucket. Start the car and watch the air and liquid come out. When it runs clear without any air, give the hose a light twist CLOCKWISE to close it up. Tighten with a wrench. In this process make sure you don't get burned from the anti-freeze or make a big mess on the driveway. Dispose of the used Anti-Freeze properly. and GO!
It is possible that your thermostat is bad. If your thermostat is stuck in the closed position it will cause your car to over hear because it is not allowing your anti freeze to circulate and cool your engine. It is also possible that after all of the repair work you had done to it that your mechanic did not get all of the air out of you engine. If you have an air bubble in your cooling system it will cause your anti freeze to basically vapor lock and this will also cause your car to over heat. To see if you have air in your cooling system simply remove your radiator cap when the car is cool then start the car and let it run at an idle for 20-30 minutes. If your anti freeze level drops a little be sure to add some. After you idle your engine with the radiator cap off for the 20-30 minutes it should remove any air that you have in your cooling system if that is in fact your problem. I hope this helps you out, and good luck.
An intake gasket could cause both problem but you would notice a loss of anti freeze. You said you just replaced the thermostat. With that in mind I think you may just have an air bubble in your cooling system. Before you go and spend alot of money try this. When your car is cool take off your radiator cap then start the car. Make sure you keep an eye on the cars temp. Keep in mind that the temp will run a little hot, but don't let it get into the red. Have your coolant in hand. Let the engine run with the radiator cap off. The anti freeze in your radiator will raise and fall as the thermostat opens and closes. If any coolant spills out ad a little more. Do this for 20 to 30 minutes. If you have an air bubble this should get rid off it. I hope this helps you out.
