Hi

This is my first Honda that I will be working on by myself. I have one major concern and two minor questions. Thank you in advance and very much appreciated for any guidance’s.

Major Concern:

During a heavy rain, I see small amount of water dripping from the interior fuse box cover underneath the steering column on the drive side carpet flooring. I pulled the cover off and I don’t know where the water is coming from.

And, I also see large wet spots coming from the Fuel Fill/Truck Door Release/Valet Key area. So, I pulled the up the carpet around the Fuel Fill Release and I can’t find where the water is coming from. Also, I do not see water between the driver door and frame, inside the door panel, and the door/window seals are good. The moon roof is dry, no water build-up, and the drain plugs are not clogged. I also sprayed air into the drain plugs. Putting a heavy thick towel near the release/valet key area soaks up much of the water.

Two minor questions:

I’m going to replace the front disk bake pads. I don’t feel any pulsation during braking, so, do I need to resurface the rotors? I hear no, but, I also heard its best to resurface because of the front wheel drive. Any thoughts?

Is it better to just drain and fill or flush coolant?

When leakages occurs during heavy rain, there must be somewhere that is allowing water to gain entry. Since the carpet is wet, remove it to dry out and perform a water test with a garden hose to locate the leak. Without the carpet, it would be easier to locate the leak. Water getting to internal components is going to short something some day so it is best to get it rectified asap.

If the rotor is fine, I do not see any reason why they should be refaced.

If the coolant is in bad condition, it is best to flush before replacing. Likewise, if you do not know the brand of the coolant in system, it is best to flush before replacing. Mixing different brands of coolant can have dire consequences if they react badly.
