2002 Accord V6. 3.0
310000 milesAlways ran great aside from a noise that lead me to adjusting valves
​
​​​​​

I just did a valve Adjustment today and after putting everything back together, it is idling right around 1000rpm and there is a drip of coolant from the hose to the intake manifold? Any ideas? When adjusting the valves I was sure to use to proper feeler gauges and from my opinion there was a slight drag on each one. Now running at 1k idle and small drip from the hose directly underneath the intake. Idk if I messed or what happened.

 

The 1000 rpm issue sounds as though you may have a vacuum leak, disconnected or cracked hose?

Coolant drip would be from moving stuff around in the engine bay, may have pushed something and caused a hose to come loose?

 

I found the hose that the coolant is leaking from. It is connected to throttle body, it must have a hole in it...I wasn't aware coolant lines went through the throttle body. The vacuum leak I will look for that could be valve cover seals, intake gasket or any of the lines I had to disconnect to tear down for the valve adjustment?

 

This is the hose that is leaking...what is this hose? I am going to replace but I am not sure what to tell parts department I am looking for

 

That is the coolant hose for the Fast Idle Thermal Valve / Rotary Air Control Valve. Not sure if it is the supply or return.

I got a new hose. ..it runs from the block upto the throttle body
