hi to everyone.
first, sorry for my english.
A weeks ago, my civic started to overheat, only in uphills (freeway). I had a new Radiator so I installed, bleed the coolant system, changed both radiator hoses. Flush the coolant but it still overheating.
I replaced radiator cap, thermostat, waterpump, timing belt, timing tensioner pulley, valve cover gasket, set timing.
And then, my car started to overheat in city traffic or when I turned on the A/c.

I did the head gasket test (cilinder compresion, leak fluid etc), and showed that the gasket was fine, but with this video, people said me that it must be the head gasket.

I replaced the head gasket with an OEM part. Rebuild head (new valve stem seals).
Everything like in the FSM says.

And the water in the radiator still flows like in the video. So. I did it wrong?

Now, the fan it is direct, no thermostat, and my civic still overheating.

The fan works fine. Flow enough air. The radiator is new. So, i dont know what happened.

please help me.

 

in the video, it doesnt seem like you, filled and bled the coolant correctly. you should have coolant to the top of the neck and in the overflow tank to the correct marking on the tank.
did you replace the head bolts or use the originals, i've seen some headgasket leak, when using original bolts. check your torque specs, fill and bleed coolant and make sure its 50/50 mixture coolant and not straight coolant.

hope it helps...

 

In the video, I'm looking for a head gasket leak. Thats is the reason for the coolant level.
I used the originals bolts with some oil like in the FSM says (torque spec, loose and tight order)

 

Help please

 

you might have a warped/cracked head or block


and what steps did you take to bleed it?

 

Does the radiator fan come on?

 

yes

 

 

agree with the possibility of a warped head and or block. try running it without the t-stat. lack of bleeding wouldn't do that at least I've forgotten to bleed it and never experience that.

 

its a cracked head or block for sure atleast only thing i have ever seen blow coolant out like that

 

Did you have the head milled?
Also, the orings in the water pipe along the back of the block could be leaking and sucking in air causing cavitation of the water pump. This would also cause foaming and overheating.
Otherwise your block surface may be warped, eroded or have defects on the top of the cylinder sleeves causing leakage.
The block and head should be refinished to a specified roughness (Honda has a spec for this). If you don't resurface (refinish) these mating surfaces your chances of a successful seal are lowered.
