The assumption is, the engine is hot and if you open the radiator cap you will be sprayed with hot radiator coolant. If I'm not mistaken, didn't the 95 Buick use the "permanent" radiator coolant? If so, don't change it until the specified time. Just don't open it while it's hot. Do it when the car is cool.
See "Changing the Coolant" on page 16 in Chapter 11 "Maintenance and Service" of your "OWNER'S MANUAL".....
The Fiat Punto has a radiator which receives coolant in order to keep the temperature down. The diagram of this radiator can be found in the owner's manual.
remove the radiator cap, place a bucket under the radiator, open the drain valve located on the bottom/ inside of the radiator, and wait till it stops running out, then close the valve and refill with 50/50 mix coolant and water. check your manual however because you may have extended life coolant that does not need changing up to 100,000 miles.
After radiator has cooled down remove radiator cap. In the center underside of the radiator is a drain plug unscrew it and drain until all coolant is empty. You will have to locate the bleeder screw in the head in order to drain the fluid in the head and not just the fluid in the radiator and lines. The screw is near your throttle body on the head of the engine (top and center). It is hard to explain where without pictures, but I suggest getting a simple Haynes or Chilton's manual. For simple things like changing coolant they really help and the money you save by doing this yourself once will pay the manual off.
Bottom or rear of radiator
Engine coolant in an Alero is used in the radiator. A diagram and instructions for how to properly use the coolant can be found on the package instructions. An owner manual will also assist in proper use of coolant.
Yes, if the coolant is still clean and has not been in the system for long. But if you are changing the coolant at the recommended mileage of your cars manual then it should not be reused.
The Best coolant for your 350Z is the original coolant from Nissan or a coolant with the same color the you have in now in your vehicle. Some cars need a special type of fluid which you can check in your owners manual.
The later models (2003 (I think) on) do not have a drain cock. The manual says to remove the lower radiator hose at the radiator. Nice touch, GM!
No. The expansion tank will not let coolant drain into the radiator. Doing this will cause the whole system to be clogged up. WHO POSTED THIS MISSINFORMATION. OPEN A REPAIR MANUAL BEFORE YOU ANSWER QUESTIONS.
Start with a cold engine.Remove the radiator cap and fill the radiator with Dexcool coolant (I think it's a red/pink color, not the usual green. DO NOT use any other product.)If the radiator was very low, start the car and add coolant as far as you can. Running a cold engine without the cap won't harm anything and allow air to escape from the cooling system.Replace the cap and add coolant to the overflow bottle. I fill it to the "cold line" so that I can see if it needs more over time.Drive the car and check for changes in the cold level. If coolant is still being lost then you must decide if you want to continue replacing coolant or take it to a shop for proper repair.
the radiator is the lowest point in the system also everyone should have a manual for their vehicle, and the library should have a professional manual available...in the reference section, you'll have to make copies of the important sections...good luck :)
