Honda keeps overheating fixed gasket leak and I took out thermostat

Good luck!

driving at night on the freeway there is enough air coming through the grill to cool everything,but when you stop at a red light,temperature starts overheating. suspect fans not coming on.if you manually turn the A/C on,both fans should come on at he same time.

How much would repair be and what is a block check if you can please explain and my fans do turn on .

I wont know the repair until we isolate the failure. the testing stops at 60$ , so thats all you would have to pay to find out. The block check is simply looking to see if there is major engine damage from the overheating. You would want to know this prior to spending any real money on repairs or parts.
