Looking to make sure I Bleed the Air From the Coolant System Properly, after changing my T-Stat.

I searched and there seems to be about 100 different answers.....

And I am still a little unsure , so here's what I have come up with:

After T-Stat Install:

With Car Off & Fully Cool:
#1: Open T-Stat Housing Bleeder
#2: Open Radiator Cap & Fill Radiator Until Coolant Comes Streaming Out
#3: Close Bleeder

Run Car W/ Heat On Until T-Stat Opens, Then Shut Off Car
#4: Check Coolant Level in Overflow, Fill As Needed
#5: Open T-Stat Housing Bleeder Until Stream Of Coolant
#6: Close T-Stat Bleeder
#7: Open 2nd Bleeder Until Stream Of Coolant
#8: Close 2nd Bleeder
#9: Check Overflow Level, Fill As Needed

Does This Make Sense??? Is there any other tips / Tricks I am missing???

Thanks,

Eric

 

Sounds good to me. Which I had known about those bleeder screws when I do mine.

 

I would like to know this also...I had my coolant flushed and changed,,,and I still get an intermitent low cooland light...

 

That is the process I normally use. Opening up the bleeder screw on the thermostat housing and filling the radiator up, purges a lot of air just from gravity alone.

Then I close it all up and run the car up to temp. Shut it down, let it settle a few mins, and open the thermostat bleeder again until coolant comes out. To be honest, I never use the other bleeder for anything.


When I replaced the timing cover gaskets, I used a different method. I filled the radiator with the thermostat bleeder open until coolant came out. Then I closed the bleeder and left the radiator cap off for a few days (I was also doing a clutch at the same time) When I went out to the garage for a smoke, I would top off the radiator with coolant. I had very little air in the system when I was ready to fire it up after 2-3 days of topping it off from time to time.

Most likely your low coolant sensor is gummed up, or bad. This is very common on our cars. I just unplugged mine and the light goes out. As long as you are watching your temp gauge, you can tell when it's low. The sensor is located in the pass side end tank of the radiator. Just remove the battery and you can see it.
