If you are talking about the overflow bottle that mounts on the fender well they are still making them. You can get a new one from the dealer or you can get a used one from the salvage yard.

How to remove air pockets in the cooling system.

when the car is cold, take off the radiator cap. Start the car and let it run for a while. While the car is running, watch the radiator opening for the antifreeze to start circulating. add antifreeze as the level dips down, when the antifreeze starts to spill out, (A Lot) put the Radiator cap back on, as the antifreeze was circulating, it was pushing the air out of the line,through the cap opening and when the antifreeze starts spilling out, it means the air is completely out of the line.

My 2003 ford taurus overheats when driving around town, stop & go, but on highway temperature goes back to normal

I had the same problem with my 99 ford taurus. My ford taurus did exactly did same things that your vehicle is doing. runs cool on the freeway because the air is going through the radiator and cooling the water down.I checked the cooling fans, radiator and hoses for leaks also replaced my thermostat. nothing solved the problem. turns out that the new antifreeze does not come with a lubercant property any longer. you have to buy the lubercant additive separately and then add it to your cooling system when you replace the antifreeze. the lubercant protects your freeze plugs, water pump, radiator, thermastat from rusting out. Meanwhile because of the absents of the lubercant, my water pump impellers rusted out and dissolved. so the water pump had no fins to circulate the water. Luckly for me, I discovered that my car was still under warranty due to an extended warranty I had purchased when I bought the car. ford dealership replaced the water pump. Problem Solved.

Antifreeze is coming out of the transmission

Only way antifreeze can enter the trans would be through the radiator. The coolant lines on you trans connect to your radiator circulating the transmission fluid through a piping inside what is called the tanks of your radiator - the black plastic ends. It is the only plausible explanation I could imagine with 35 years fixing, though never saw it happen.

I have a 1989 f 250 truck.i brought it to a machanic and he just said that the tempature is running hot and i dont want to mess any thing up so how do i go by fixing this and what could possible be the...

Hello, That sort of sounds like he did not want to work on your truck because it might take big money to fix it.

Here is how to check a few things. When the engine is warm, not hot, take off the Radiator cap and use a flashlight and look at the water inside the Radiator. The motor should be running. You should see good flow with antifreeze circulating in the top portion of the radiator. The antifreeze should not have oil or air bubbles on the surface. Just flowing antifreeze.

If the water is flowing, no oil, no air bubbles, then the radiator is not clogged and the head gaskets are probably good. The water pump is probably good if no antifreeze is leaking from it. Try putting in a new water thermostat. Put the radiator cap back on and run the engine and look for collapsed hoses when the engine is running faster.

You can get your radiator cap checked for pressure or just buy a new one. There are some tools for checking Radiator pressure and Autozone,Advance, and Oreillys all have loaner programs. Once you have a new cap, if there is a leak, it will probably show up.

At this point, you have only bought a thermostat and a radiator cap. The rest of the needed repairs will depend on observation of the water flow I mentioned and if these 2 simple things solve your problem. I hope my solution is very helpful to you.

Antifreeze light says system is low and car runs hot but antifreeze level is where it should be

Sounds like it could be a thermostat not opening. If the thermostat doesn't open then it will get hot because its not allowing the cooled antifreeze from the radiator into the engine. Your car has two circulations with the antifreeze. While your car is running it is heating up the antifreeze in the engine and when it reaches a certain temperature the thermostat opens and takes the hot antifreeze from the engine and puts it into the radiator to be cooled. At the same time the cool antifreeze from the radiator is placed into the engine to keep it cool. If your thermostat doesn't open your engine will get hot and overheat.

My car runs hot. I have put a new radiator and thermostatic in. It has antifreeze. There is no water in the oil.

You my want to check your water pump.
your water pump circulate your coolant through the radiator and engine block
without the circulation you over heat
IF this helps please give feed back
Hope it works FixYa

My heater does not blow hot air. 1 thermstat has been replaced 2 could water pump be bad 3 water does not seem to be circulating through the hoses. 4 the air mixer under the dash seems to be workig.

If the thermostat was recently replaced, it could be trapped air in the cooling system. First, you need to establish that the thermostat is working. Remove the radiator cap and start the engine. Let it warm up to normal operating temperature on the temp guage. Make sure the heater is set to the hottest setting. Observe the coolant in the radiator. If the coolant is flowing when the engine is cold, then the thermostat is stuck open and the heater won't get warm. If the coolant is not flowing, continue to watch the coolant. When the thermostat opens, the coolant level will drop in the radiator tank, add antifreeze to bring it back to full. Each time the coolant level drops, add more antifreeze. should the thermostat close while doing this, antifreeze may spill over from the radiator tank. No to worry. As son as the thermostat opens up again, add antifreeze to fill the tank. Continue to do this until the coolant level no longer drops. Sometimes it is necessary to raise the front of the vehicle so the radiator is high than the engine in order for the air to escape. Put the radiator cap back on. If the problem was air in the system, then the heater should be warm now. In the old days we would just drill two 1/8 inch holes in the new thermostat before installing it. That allowed the trapped air to escape slowly. Might still be an option.Let me know if this helps.

What would cause it to run hot and the heat stop working at the same time?

I've seen cars run hot and the heater not work for the following reasons:

1. The radiator is frozen solid and the coolant can't circulate.
*** The fix, get the car into a warm garage and let the ice in the radiator melt. Once done, add the correct mix of antifreeze so it doesn't happen again.

2. The water pump is not working and the coolant isn't circulating.
*** The fix, replace the water pump and adjust antifreeze mix.

is the water pump working and circulating the antifreeze. if it is working, I would flush out the system and replace the thermostat before refilling system. you can buy radiator flush at any auto parts store. you can back flush system through radiator. just follow directions on back of flush bottle. have a good one!!

Overheated truck

Your radiator is getting clogged up with mud causing the lack of air flow through the radiator. You may want to install a mud deflector in front of your radiator to keep the mud from clogging up the radiator and may be run your antifreeze ratio 40/60 (antifreeze/water) the higher the water content the better the heat transfer, but your have to keep an eye on the level of the coolant level more often. Water will evaporate quicker but too muck antifreeze will have poor heat transfer and 100% antifreeze will gel when heated causing poor circulation causing overheating. Good luck and hope this helps.
