The Honda PCX / Forza / ADV150 / SH Forums

I was changing my coolant in my 2016 Honda PCX and I overtightened the coolant drain bolt causing it to snap off inside the hole.

Obviously I need to order a new screw/cap now...but how the hell do I get the screw out now? I'm so mad at myself right now. I didn't refill the coolant and I'm going to wait until I get this out to do so. Including a picture of how it usually looks too.

Can I glue the top cap to it and try to gently unscrew it?

My other idea was to heat up a flat head screwdriver and press it into that to try and create a "flat head screw". I don't have an electric drill.

If you don’t have an electric drill it means your tools are relatively sparse. Take it to a body shop or an auto repair place and they can have it out in 30 seconds with an EZ out tool. Order a new plug before you take this one out.

It turns out my girlfriends dad has a drill. I'm probably just going to buy a set of those extractors for it and ask him to help me out. Ordering a new plug and a bunch of other little spare parts to have on hand just incase for the future.

If you're getting an extractor (or extractor set), consider getting a matching reverse drill bit (or set) to go with it. Reason being that if you need to use it on a broken steel bolt or stud in the future, the reverse bit will likely back out the bolt/stud by it's heat/torque and prevent needing the extractor. It's a real pain if the extractor snaps off.

It turns out it's a plastic bolt and there's already a little hole going down the middle of it. I asked my gfs dad to take a look and he suggested the easy out tool as well and it'd be a piece of cake for him to remove. Wish us luck. New plug should be here in a week or so and we're going to wait for it to come before we take the old one out. This is what it looks like: https://www.cmsnl.com/products/bolt-drain_90103get003/

Update: I ordered the bolt from RevZilla and they cancelled my order as it turns out they don't actually have the part available. Is there another place I can order from?

Order from your Honda Dealer...............free shipping if picked up at Dealer.

Yeh set off extractors
left handed drill bit
small drill and tap a Allen key ot torx bit in
Very very mild heat with it being plastic and a pick or screw driver to rotate it

For new plug just got to a dealers or phone them i imagine it won't be alot at all

I'm not sure where you're located but PartZilla and Amazon both show the plug is available.

I'm in the US. I ordered from my local dealer and they said the part's on backorder and they don't know when it's estimated to arrive. They gave me another dealer to call, same story. PartZilla just shows "ships in 2-3 days" on my end, but other parts say "In Stock". I'll try Amazon.

FWIW, I have found that PartZilla's estimates of when things will ship are pretty accurate.

I checked their website tonight and it now says it'll ship between April 21st and April 28th now.

My dealer just said he's guessing 2 months as Honda couldn't give them a date...

Based on the photo I provided above...do you think I could just drain the rest of it from the bottom and fill it up with new coolant while the broken bolt's still in there? Then replace that coolant again when the new screws come? I'm not sure if this would work as there's also an o-ring that came off with the top of the bolt. I still have the o-ring and it's in good shape. I'm just kind of nervous about letting it sit for another 2 months because I don't want the inside of the radiator to become corroded or anything.

Guessing that o-ring normally keeps it sealed. Evidently there is corrosion on the inside of the plug holding the coolant back?? If you do what you
mentioned........fill the system and run the scooter............probably a few test runs "local" would give you a chance to test it. If it holds while up to
temperature after several attempts..........might be OK till the plug comes in. I wouldn't flush the system though until the new plug is in.
