If the car engine get hot it starts to boil all the coolant out of the water bottle and that then causes the car to over heat. its a 2004 lumina ss 5.7L V8. Please let me know on my E-mail at [email protected] Thank you
Don`t sound good, but i would see if water was circulating in radiator when warm,and check if fan comes on like it is supposed to to cool it ,if water does not circulate check hoses to make sure the suction does not restrict flow ,if no circulation you could try replacing thermostat (cheapest fix ) anti-freeze dilution (second cheapest ) or uh-oh maybe blown head gasket......
SOURCE: engine is over heating and blowing air into coolant resivor and boiling coolant
1. Do you have a cooling fan system for your car, if you have , please check it, sometimes due to the wire overheated short problem and fan doesn’t work and cause the engine over heat.
2. If the head gasket leaking, you can check you oil steak see if there is white steam oil bubbling ,if the oil has steam and the radiator has oil mixed with coolant , that means the head gasket leaking.

Double check that your rad cooling fan is operating as it should, but after that, I'd be looking at a good rad flush, or rad replace. Believe it or not, your heater core is like a small rad, and when you turn the heater on, it actually cools the circulating coolant, slighly,and therefore shows a difference on your gauge. Like I said, make sure the rad fan is coming on when engine temperature is at normal or slightly higher, and if it is, then I'd be taking a close look at my radiator, especially if it wasn't replaced when headgasket was done.

I have a 2004 4.7 dodge ram that the coolant gauge goes to 3/4 when towing my bass boat in the afternoons on hot days,I had the water pump replaced because it was wobbling at the pulley,covered under 7/70 power train.Acouple of weeks later towing again had the same problem,the turn on the heater and all is well after 2 to 3 minutes,replaced thermostat and saved and re-used coolant dealer put in and problem still there.At this point I contacted the techs at the dealer and talked with them and we all agreed radiator.Removed the radiator and took to rad shop and had it checked,found radiator plugging up,Now as to why.The antifreeze that chrysler uses is a HOAT type antifreeze,hybrid organic acid technology,with silicates and friction modifiers,this antifreeze CANNOT BE USED WITH TAP WATER OR WELL WATER OF ANY KIND,as it states in the owners manual.Only 1 dealer in this area apparently knows this but this is not the dealer that i took it to.The silicates in this antifreeze when mixed with the wrong water type will seperate and and become heavier and then start to gel and plug the passages in the radiator.This truck only has 46,443 miles on it and mostly used just to tow the boat.Hope this helps everyone else with this problem.Will be contacting Chrysler about this and the improper repairs that are being performed at their dealerships.Lester [email protected].
1st, test the water pump and make sure with the belt off, that it turns freely now that you've installed it. Sometimes the impeller is not pressed on completely, and these don't turn properly.
Maybe you did this but just in case:
Always free spin anything installed , IE: water pump, oil pumps, alternator, generators, camshafts, crankshafts, etc., before moving to the next step.
2nd. Verify the belt installation. With today's serpentine belts, a wrong turn may cause the pump to run backwards, but seem correct. There should be a specific diagram under the hood or on the fender.
3rd. If the Belt's OK, Pump's OK, and you have properly installed the new Thermostat. (I have seen them installed upside down and they won't work that way.) If you filled it properly, making sure it was 100% full, then you may be dealing with a blown head gasket, cracked head, or a cracked cylinder wall.
I hope this helps & good luck!
