Bleeding the System


IF YOU CAN ELEVATE THE FRONT OF THE CAR ON RAMPS OR JACK STANDS IT WILL HELP

Start the car and let it idle until it reaches operating temperature (usually about 1/3 up the temperature gauge). Rev the engine to 3,000 RPM and hold for 10 seconds. Repeat 2-3 times. Check for any leaks.

Stop the engine and let it cool down. Let the engine fully cool, as you'll be opening the radiator! If you don't wait long enough, you'll scold and burn yourself! After the engine is cool, pop the radiator cap (be sure to use the quarter turn to relieve pressure first, then open fully method), and refill up to the neck if required. Refill reservoir tank to MAX level line with coolant.

Repeat the above steps of running the engine and let cool cycles until the coolant level no longer drops. Be sure to check for leaks each time.

Now warm up the engine, and run the heater in the car. Check for noise in the coolant system (noise will be air going through the pipes) and rev the engine up to 3k RPM. Repeat this 3 times. If you continue to get noise in the hoses, start again at the top of the process for bleeding.

You're all set! Problem signs you should look to know if you've screwed anything up
- Leaks
- Sudden rises in water temperature in the car
- Heater failing to get hot

 

man i no this might sound crazy but i had a problem with overheating and the heat blowing cold for about 6 months..ive changed t-stat,cap,bleed the crap out of it useing one of those spiecal funnles and i still was haveing heating issues..well 2 days ago i brought it to the shop to get my clutch checked out and get some new belts installed and when i went picked it up i turned the heater on and for the first time it blowed hot air while idleing..ive only had my car for 2 days cause its back in the shop getting a new clutch and for those 2 days i didnt have any over heating issues or cold heat..so maybe the new ac and drive belt fixed my heating issues(?) i hope it did

 

Its a miracle. Belts don't have anything to do with it. Did you ever try using the air relief plug on the heater hose?

 

hallelujah lol
yea did just about everthing had the mechnic also do a compression test to see if the headgasket was messed up..
it only dose it everynow and then in the morning for the first 15 mins of driving thru the city the temp guage will start clmibing up and ill cut the engine off for about 5 mins and itll go back to normal.the fans are working cause i hear them running

 

You use OEM parts? Are you sure BOTH fans are running?

 

before the new belts when i use to turn my heater on the belt will make a loud screching sound for about 2 mins..so u sure the belts have nothing to do with it?

 

yea both fans where running for sure

 

They have pretty nothing to do with the cooling system. The water pump isn't drive belt driven.

 

OEM parts?

 

No they were autozone parts lol probably why..it hasn't overheated since I changed the belts but I've only had it for 2 days so when I get it back ill see if still overheating and if it is I'm gona replace everything again with oem parts

 

Ok question: when I turn the heater the ac belt turns..right?or dose the ac belt just turns when the "ac" on cold?

 

The A/C belt is always moving because it's connected to the crank pulley. The A/C itself won't kick on unless the A/C LED is on. You can hit the A/C button to turn it off and just run straight heat.

 

Had this similar issue...it was due to not having a OEM cap.
After OEM cap was replaced, it solved the problem.
