Cooling fan should turn on at least once in 15 minutes of idling.Did not check for cooling fan operation. What's protocol there?
I have a CVT that the original owner dropped a LOT of money chasing a cooling problem. The cooling eventually led to overheating and a head gasket replacement at great cost as well as other issues.
As part of the cooling system servicing, ensure that the black tube descending from the coolant capture reservoir is in place. This tube fell off on this car causing air to be drawn in instead of coolant when the car cooled down, and was the core cause of the overheating problem. This has been reported on at least one other car in this forum.
The tube slides onto the cap and there is no barb to keep it on. I modified the cap to create barbs and then used wire to secure the tube and make sure it does not fall off again.
It probably is a good idea to use a marker to mark the coolant level in the capture tank when the car has cooled overnight. The coolant level should rise the same amount every time when the car is hot and fall back to that same level overnight. If it drops below this, and you find yourself filling it more than once or twice, you should consider looking for the leak. There is a possibility that air that may collect in the top of the cooling system may be one of the factors of cam failure (though a plugged VTEC screen has also been found to be a likely factor).
