coolant

[charleslong]

when the coolant in the top up tank is cold the level is ok but when hot the level is high is this ok or is thare a problem in the radiator

That is the point of having a "recovery tank." As the coolant heats up and expands it can overflow into the reservoir. When it cools off it will suck some of the coolant back into the radiator. If it seems to be happening too much (like overflowing the recovery tank) it may be that the radiator cap's spring (or seal) is bad allowing too low of a pressure before relief. You could replace the cap easy enough if in question.

Hi Charlie.

Have you ever flushed and changed the coolant?

As far as I know, mine has never been changed, so I am going to do the '********' https://fjrtech.net/getdbitem.cfm?item=43. Seems a little 'over the top' to me, but it's a procedure that comes highly recommended.

Cheers.

I never understood the point of the "blow-job" coolant change method. As long as you are using the same stuff, drain the system, empty the overflow reservoir and refill with antifreeze diluted 50-50 with distilled water (or premix). If you are changing to a different coolant, I would fill with distilled water and run it long enough to cycle the thermostat, drain and refill (using something a bit stronger than 50-50 to account for the distilled water remaining in the system). I used half the stated system capacity of full-strength AF and topped off with distilled water after a distilled water flush.

A bit of residual old stuff isn't going to hurt anything. Would you open up your engine to get ALL of the residual oil out when you do an oil change?

+1 - You are starting to sound just like me, Ross. (I don't know if that is good or bad for you)

The only possible reason to do the full Flush and ******** is if you will be switching to a different type of coolant, such as the OAT Dex-Cool that is recommended in the ******** Procedure write up. Personally., I would never use Dex-Cool in my FJR, but other folks have apparently done so successfully. So, YMMV

The main point here is you do not want to mix OAT coolant with conventional coolant, as they are incompatible, so the flush is required.

 

[RossKean]

I did a 2x distilled water flush when I changed to Dex-Cool a couple of years ago. I did a little reading about the stuff with its potential problems and elected to change back to the green stuff. Again, I did a 2x distilled water flush before changing back. I change coolant once per year - not because it is in any way "worn out" or contaminated, but because it is easy, inexpensive and makes me feel good.

 

[SkooterG]

Yup. Just drain and fill. Follow the KISS principle.

 

[kamal]

Thank you! Sort of what I thought so, as I'm sticking with Prestone 'made for all motorcycles', I'll just do a mini flush.

Hope this helps you Charles? (to stay on topic

I'm also a 'drain and fill' guy but if you buy a gallon of the the concentrate, not the 50/50 premix, you get enough for 2 drain and fills. So I change the coolant, run it for a month or 2 then change it again. Sure it's a little overkill but it's simple and gives me something to do on a crappy weather day. I'll take a couple hrs that day to check over my winter work, especially for leaks, loose fasteners, etc. and it's a feel-good coolant change. The added plus is that the wife won't bother me for at least a couple hrs.....

Don't believe the OAT long-life coolants are incompatible with the older coolants. You can combine them but the long-life characteristic will be lost with the mixing. But, can easily meet the recommended two year replacement schedule specified by Yamaha.

"Prestone® Extended Life Antifreeze/Coolant is compatible with ANY antifreeze/ coolant – regardless of color – for use in ALL makes and models of cars and light duty trucks."

I've been using Peak Global. It's an OAT2 blend if I remember right. It too is compatible with all other brands and colors. It doesn't have the issues that the Dexcool stuff has either.

Oats in the cooling system? Whats next, wheat?

Gotta have it - reduces cholesterol in your cooling system.

I put pravastatin in my coolant.

I'm a 10,000 mile per year guy and I change the coolant every two years. Bike is garage kept where it never gets very warm or cold. I use the Honda 50/50 coolant. It is readily available and not that expensive. The ******** is not hard to perform and it will get most of the old coolant out of the system. If you are a high mileage rider then change the coolant every year. Coolant contains important additives to lube the water pump and an anode to prevent errosion.

I'm confused. I drained the coolant from my FJR then told my wife an easily performed ******** would be needed to get the remaining fluid out. She said no, now I don't know how I'm gonna get the rest of the old coolant out.
