![]() The problem is that you cannot ever get all the tap water out of the system before refilling unless you remove all hoses at the lower level and that's definitely not recommended. There are minerals in all tap water wherever you live in the world and these minerals damage water pump seals and can cause other issues. Wherever you live, never use a hose to flush your motor. As you didn't put in very much it's unlikely to have caused any permanent damage. If left, blockages and leaks will often occur but it can take a few months to a year for this to happen depending how much of the new stuff you put in. The issue is one of blockages occurring when the two coolants interact with each other. Get it all out now! If you drain and flush a couple of times that should be all that's needed. As I suspected, you cannot mix Coolanol with existing OAT coolant already in your Vespa. I'd do a complete flush and refill with new coolant. Should I do a complete flush now or is it ok to top it off with distilled water from now on? ![]() Sorry for my previous post that it was ok I was obviously wrong. I just emailed Scooterwest and they said Coolanol is only good for a complete flush.not topping off. I topped off my coolant about 400 miles ago with about 6-8 oz. I think it was Motul.Īnd does anyone fill with water and descaler the way the Hayes manual suggests?įor this change, I bought some Coolanol from Scooterwest, on the assumption that they would have whatever is best for my scooter. At this point, I guess the question of whether it was OAT or compatible with what came in the scooter is moot. I also just bought coolant at the motorcycle shop, (my Vespa shop having closed down). I feel like I just drained the old coolant and put more in the one time I've done it, since I mistrust running tap water through. Would it be better to pour a couple of gallons of destilled water through, rather than flush with a hose? Or, since it's not staying in the engine, except for a small residual amount, is it OK to do a thorough flushing with the hose? Just to add more questions, because I am going to change my coolant again this summer - the Hayes manual says to flush the radiator with a hose, fill it up with the hose and some descaler, run the engine, redrain, and then fill with coolant. You could phone Scooterwest for a chat about it to confirm it's OAT (it probably is but it doesn't say it) and double check it's suitability. I pointed this out to him and he immediately took it down. That is for use in Vespas! It was supposed to be only sold for use in Kawasakis but the site said it was ok for our scooters too. A top Uk dealer here down the road from me was selling a completely inappropriate coolant for use in Vespas without knowing he was selling it. The fact a top Vespa dealer is selling it does not mean it's automatically ok in your Vespa even if they say it is. Unfortunately, the damage can be permanent. The most common issues arising from using the wrong coolant are leaks and blockages inside the motor cooling system. Engines can be touchy about this sort of thing and you won't necessarily know if it's ok for several months after putting it your motor. It's pretty clear what you can use and what you cannot.Įdit: just looked it up on other sites and it's definitely not one I would use in our workshop for a Vespa without knowing more about it. Check your owners manual for the specs required. So I would suggest you can only use it after you completely flush and refill with that stuff. It doesn't state it's a genuine OAT either. That means it's got silicates in it so it's probably fair to say it's totally unsuited to mixing with the existing OAT coolant in your Vespa. Colour doesn't matter but the type of coolant it is does.Ĭannot see what the exact specs are but it states it's an extremely low silicate product. They all tend to be different in some way and this can cause damage.
