Where is the block drain on a Honda Accord?
It may not be in the owner’s manual, but it is in the service manual. The block drain is on the rear side of the engine, toward the passenger side. There is a nipple coming out from inside the nut, so you can fit a drain hose on it, then loosen the nut.
How to change coolant in a Honda Accord?
There is a procedure for doing the coolant change, which includes turning the heater up full hot (before draining), and starting the engine with the radiator cap on loosely (after filling), then running the engine until the fans come on at least twice. It’s not as simple as drain and refill. Good luck Good advise from BLCKFLSH as usual.
Is it OK to drain coolant on a V6?
The old stuff is not poison- just fluid that needs updating. But yeah, if you are doing the timing belt (on a V6), do the water pump too and exchange 100% of the fluid! Going through the trouble of draining the block of coolant is absolutely not worth the extra drainage.
Do you drain the radiator or drain the block?
BLCKFLSH is correct. The honda SERVICE manual not the OWNERS manual states to drain the rear of the block in addition to draining the radiator. And as BLCKFLSH stated, a good amount comes out from the rear block drain. It is in a very tight spot. I removed the front passenger side wheel for easier access.
