Hey everyone, so im currently in the process of bleeding my coolant, but I can NOT get the air out of the system or get hot air.

Second my fans are not kicking on.
Exactly how long do you have to run the car to get it hot enongh.

My biggest question CAN THE MOTOR OVERHEAT AND RUIN ITSELF WITH BLEEDING THE COOLANT?

im just worried about overheating the engine and not knowing it, ive been monitoring my coolant temp and its at 3 bars.

What exactly am i doing wrong?? Im following the diy coolant change for dummies, but no luck. Any help would be appreciated, thanks everyone

 

Did you run the car for 15 min? Afterwards did you turn the car off? Then did you open the bleed valve? then while the bleed valve was open did you squeeze the top radiator hose hose a couple times until fluid comes out? did you close the bleed bolt with the top radiator hose squeezed so you don't draw air in the system? did you repeat this process two or three times? if you answered no to any of these questions you're doing it wrong.

 

Tomorrow im going to jack the front of the car tomorrow, and when squeezing the top radiator hose, when i do it i can hear it sucking air back in, so would squeezig it and holding it 1 time work better?

 

I used a mityvac hand held vacuum pump to pull 3 containers (about 6 oz each) of coolant out the heater line bleeder and 1 out of the head bleeder to get the air out.

This was after I thought it was bled, and drove it, using a scanner and saw temps going to 220, so I shut it down and coasted (no heat as it got hot). I had to start it and saw 239, and shut if off again. No fans either.

After bleeding it, temps dropped to 180, and the fans come on at typical Honda 203.

 

Yep squeeze it until it's only fluid coming out, do this two or three times and you should be set.

Sometimes running the car at idle isn't enough to get a good flow of coolant. Sometimes you gotta drive it to really flow. Take it for a spin around the block instead of waiting for it to fully warm up at idle.

 

^ what he said.. that what i did i usually do mine a couple if times to make sure all the air is out.. good luck you can do this

 

I had exactly the same issue.
What I did:

Car off and cool, I removed the small cap on the top of the engine (near the windshield)
I put a transparent plastic tube on it and sucked until coolant went out.
Then, I replaced the cap, and followed Billman's instructions:

With this process, you can't be wrong, follow all steps and you will resolve your issue, I resolved mine

 

sometimes idling doesn't create enough heat or flow, and it can take a long time to get the fans to kick on. I often manually run it at higher rpms using the throttle body plate with the hood open, just keep an eye on the temp gauge, I go back and forth checking it during the procedure. That should get the fans to kick on quicker.
