Changing coolant

[Corringdon]

My CR is now three years old and the service interval manual states that the coolant should be changed every 3 years. I am considering undertaking this task myself and was wondering if any forum members can offer advice. I am loathe to have the dealer do this as their charges are astronomical. Many thanks.

Hi Corringdon, i did mine late last year. Quite simple to do as I had most of the side panels off to repaint the front of the engine which was looking tattie. The rad cap is on the right hand side for refilling. Removed bottom hose to drain out old coolant. Used genuine honda coolant as stipulated in manual. Others are available but for all the cost difference I thought what the heck. Remember to fill header tank under the seat to correct level and check after a few minutes for airlocks.
Regards

Thanks for that info, Goggins. I was wondering if you had any problems with air locks or cylinder head draining as the manual states that special tools are required.

[Goggins]

Nope, no issues what so ever. Whether I got all the original coolant out is anyone's guess. What I will say is when I did reinstate the top rad, i put tbe two small pipes on the wrong way. When the engine was up to heat, it displaced some coolant through one if the 3 pipes that drop down from the bottim of the bike. A quick change over put it to the expansion tank. Hope this helps.

Thank you for your advice, Goggins. You said you had to reinstate the top rad. Did you have to remove it?

[Goggins]

Yes I did, but that was only because I took it off make painting the engine easier. As for the coolant change, I'm sure it could be left on.

Does the manual still stipulate blog the throttle to help remove airlock? It did for previous VFR models.

Also, with the coolant filler cap removed, lean the bike as far over to the left as you can, preferably with the assistance of a strong friend. This often releases a few bubbles. At least st it used to on previous VFRs.

Thanks Goggins.
Skids. The handbook/manual says sweet FA except that the job requires special tools and therefore should be left to the dealer to attend to. Thanks for the advice on leaning the bike to remove extra air.
