Make sure you only have 1/3 of the overflow tank filled with antifreeze when the engine is cold. After a drive and the engine fully heated if it overflows after being shut off you have a head gasket problem.
You will see several tanks under the hood. One will show a windshield with a wiper blade, this is not the Radiator tank. Another should follow a small rubber line from the Radiator and may say "overflow". This is the correct tank.
If the Antifreeze is LOW you need to pressure test the Radiator and system for leaks. The Antifreeze should not get low. It means there is a problem.
There is a fill line for Cold and Hot on most tanks. It is normal for the level to fluctuate.
If you are really in doubt, go to Autozone, Advance, or Oreilys and they will show you where the tank is.
I'm not completely clear on what you mean, but here are some things to check. 1. Check the hose from the radiator neck to the overflow tank for cracks or leaks. If it's leaking the tubing can be purchased at an auto parts store. It's very inexpensive.
2. If it's leaking a lot into the over fill tank this could be an indication that your radiator cap is leaking at the seal, allowing coolant to bypass the spring on the cap and through the hose into the coolant overflow tank. Replace the radiator cap, these are about $10.
First check hoses and water pump while car is hot and running. If you find nothing then let car cool down and fill overflow container. Get engine hot again. When engine is hot turn off car and check the overflow tube coming out of the overflow tank. If it is spitting antifreeze then you have air in the system. Bleed system by opening the 7mm bleeder. You may have to do this a few times until all air is out of the system and overflow stops spitting antifreeze.
Look at your overflow tank, these caps have a psi rating and if the seal gets old the cap won't hold the pressure and releases small amounts of antifreeze. Sometimes the overflow tank will be a powder looking in spots from the hot water leaking out.
I would check for visible cracks and leaking at the overflow tank when the engine is cold, then when the engine is running and at operating temperature and not running and at operating temperature as well as during cool down. Also check the coolant overflow hose for leaks or obstructions inside the hose or if the hose is kinked. Check to make sure that the overflow tank cap is damage free and securely fastened.
A rubber pipe isn't sealed properly by its metal collar, probably because it has aged. Tighten all the collars and plan for a close future replacement of all your water pipes.
Yes, oil in the antifreeze typically comes from a blown head gasket. To verify, start the truck and watch the overflow tank you should see what looks like a back flow or bubbles. By the time the truck get to normal temp, it'll be obvious.
