The Honda PCX / Forza / ADV150 / SH Forums

So, just about near my 600 mile marker, and I noticed my coolant was extremely low, as in hovering at the low mark on my reservoir.
I read about bleeding and during the break-in this can happen, so not fretting it.

Should I replace or top off.
The scooter was an unused pcx150 2016, that was sitting at the dealers for quite some time.
I must presume its Honda Blue-2, but should I replace it out right, and if so, any one have the service manual I could have to help me along, or have been gracious to create a how to guide/video?

If I top-off should that be distilled-water only? <- I wanted to confirm that as right/wrong.
Or should I just drop in more HBlue2?

Thanks!

If you are going to let the dealer do the 600 mile service, remind them when you drop it off. Otherwise, buy the 'recommended' coolant from the dealer and top it by way of the overflow tank. When I purchased some they sold it by the quart, I believe. I have 2013 model and my overflow tank is accessed from the storage compartment. I am not sure if the newer models access it the same way.

And here's how-to Top-it-off EZ, do read the whole thread. Cheers!

Take it to the dealer and have them inspect it.
Then they can determine why its low and repair accordingly before any further damage is done.
Its what the warranty is for....

Forget that. Get the dealer to sort it under warranty

If convenient to ride to the dealer and wait several hours ,or dropping it off then getting a ride to get it works for you then that would be best.However you can also add a few ounces of 50/50 mix antifreeze to top off and go merrily on your way.Just watch for any loss or abnormalities.You did not indicate you observed any abnormal leakage or any overheating.If you observe continued losses then you will need to pursue further diagnosis and then your warranty should be utilized.

Can you explain how you would detect overheating on a scooter with no temperature gauge before it becomes a problem...?

The scooter HAS to go for a proper check by an expert to see exactly what the problem is. Or isn't.
Could be the usual crack in the expansion tank or it could be absence of a cylinder head gasket.

None of us can accurately diagnose it from a forum post.

If it was a crack there would be spillage,if it was no head gasket which is doubtful it would run badly because liquid would foul the engine spark plugs,and he said it never overheated and if the res was just a little low then it would not overheat.There was no water coming out of the exhaust.Sooo it is up to the owner if he has the time ,loss from work,or needing a ride or trailer..may all be for nothing if the reservoir was not filled properly.You may be right and it may need some serious repair but doing some DIY checks may save the person a lot of time and inconvenience and expenses.

However you can also add a few ounces of 50/50 mix antifreeze to top off and go merrily on your way.Just watch for any loss or abnormalities.

I'd do this first. Just fill the overflow tank to the proper level and see if it continues to drop. With only 600 miles on the engine, the overflow tank may have simply done it's job and filled an engine / radiator that wasn't properly full from the factory.

If you've already done this and the coolant level has continued to drop, that's a different story and I'd get it to the dealer to resolve the leak problem.

This is most likely the case. The last new cars I have had have done that. Coolant dropped in the first couple of hundred miles and then remained constant.

Ok, went down and picked up some Honda Blue-type 2 from my local dealer. Topped her off. Checking her before and after each ride and no changes so far! Thanks for the help and advice, I'll update here if anything changes!

Sounds good so far!

If it's going to show a problem, it will be after the engine has had a chance to cool down and fluid contracts - and thus "pulls back" the antifreeze from the overflow tank into the engine/ radiator.

If the overflow tank level rises a little bit when the engine is hot and then falls back to a constant cold level after several hot/ cold cycles it means your system is purged of all air, and the overflow is rising/ falling just a bit due to fluid expansion/ contraction as it's designed to do.

quick update here, no change to the coolant level since topping the scooter off with the Honda coolant!

Good news, and thanks for posting that update !
