I just bought my car and I'm going to be changing out all the fluids and filters since it's a very low mileage MY2000 and probably hasn't had much service done.

I guess the DIY for coolant flush has disappeared, but I have a copy of the service manual that says to use liquid gasket for the coolant drain bolt in the engine block. I'm getting Hondabond for doing the oil jet bolts. Could I use that to seal the coolant drain bolt, or will that make it too hard to get out later? I don't know how hard of a material it is once it cures.

Thanks.

you don't need hondabond for either of those jobs. just correct torque.

I meant Hondabond for the oil pan. So I don't need to use anything on the coolant drain? Because there is no washer, right?

I believe the coolant drian bolt on the block does use Hondabond, I've always used it on every Honda I've done in the past and the manual does recommend it. The chance of leaking is small but that bolt is such a pain in the ass to get off, you might as well do it right if you have to good fortune of getting it removed. Hondabond works well.

Thanks. I mainly wanted to make sure that Hondabond isn't something that will make it too hard to get off later, because I've never used it before. But it sounded like a good thing to use, so I'll go ahead and try it.

it is a non-hardening sealant so it won't create any resistance in getting it off in the future, it's good stuff. But that bolt is a major pain the ass to remove, I gave up when I did my coolant change, you might find it easier to pull the lower hose at the block rather than that bolt, sometimes it is just easier.

Yea I would agree just pull the hose rather than the bolt. Made life so much easier. Repiv has a write up on S2kca also on coolant change that I followed and turned out great.

the manual specifies to use honda bond on the coolant drain for the block im sure you could get away without it but why risk it when the manual specifies to use it? its a soft material and can be removed with zero problems in the future.

I pulled the hose and didn't get any more than just a few drops more coolant out after draining the radiator. I don't know if that's normal or not, but I'm not worried about it because the coolant looked really clean, so it probably has been changed before. It certainly didn't look 10 years old. So even if I didn't get it all out, at least what's left is pretty clean.

I think that's the way it works, there isn't much more that comes out of the block if you drain the rad first given the drain cock is the lowest point in the system.
