Ok, I changed out my coolant Saturday, so I thought I would go ahead and take some pics along the way.

The bike doesn't need to be on a stand, but it makes things easier to get at.

First thing is to remove the tank. Check out Bassdudes link here. http://www.vtxcafe.com/showthread.php?t=33679&highlight=tank+removal

Image


Then remove the radiator cap.

Image


Remove the left side cover, and left side trans cover.

Image

Image
Image



With a pan under the bike to catch the fluid, remove the cooling system drain bolt, and allow coolant to drain completely.

Image

Image


Reinstall the drain bolt with a new sealing washer.


The manual calls for removing the siphon hose from the overflow tank and draining, but I chose to remove the entire tank and drain and clean. You only have to remove the filler neck, and one mounting bolt. There is a rubber grommet that holds the right side of the tank so don’t lose it.

Pull the tank down as far as possible and then remove the siphon hose and hold your thumb over the inlet while removing it the rest of the way.

Clean and reinstall the overflow tank.

Fill the system with a 1:1 mixture of silicate free ethylene glycol anti-freeze and distilled water up to the filler neck.

Image


Set the tank back on and connect the fuel and vacuum lines and run the bike at idle for 3 minutes. Give the throttle a few rev’s to work any air out of the system.

Top off the coolant at the filler neck, and replace cap.

Fill the overflow tank to the high mark (I used a squeeze bottle and filled it before reinstalling the filler neck) and replace cap.

Image



Wipe everything down, check for leaks, replace side covers and you are ready to roll. :choppersm

If I missed anything or anyone has anything to add feel free.

Great info! Thank you! :cheers:
Thanks guys.


Question, after you put in the new coolant, do you leave off the coolant cap when you sit the tank back on and run the bike for 3 minutes? Thanks for the excellent write up and the pics....
Leave the cap off, your only running it long enough to get the thermostat open and purge any air out of the system.

Nice write up there. Great pics!!

How much coolant total did you add to the system?

Now when its done this way, does it drain the radiator, block, and hoses as well?

Could of used this two days ago.....very nice write up.

I removed the entire overflow tank as well. I had trouble removing the overflow tank hoses from mine. They refused to come loose and those clamps weren't going anywhere. I ended up disconnecting the overflow filler cap and removing the entire filler tube with the overflow tank still attached.

Good point Charlie, I did just that, as well as the side stand. Also changed the engine and final drive oil, and several other items.
Installed some passenger grab rails I made up for the wife and daughter also.

This is per the manual. 2.9 qts for the engine and radiator, .25 qts for the overflow tank.
I assume it drains as much as possible without total disassembly.

I used Prestone from the local auto parts store. The main thing is make sure it is silicate free so it doesn't damage the water pump, and use distilled water to dilute it.

The pictures are worth a thousand words! Very nice write-up. I called the folks at PEAK last week because their containers did not state if it was silicate free and they told me it was free. The technician I talked to said they have received many calls asking the same and by late summer the containers should state so. This is something I need to do before summer hits....Again, great pictures!

First of all, thanks for the great tutorial here jstar... I will be doing this as well, I assume that an 1800 is pretty similar in this regard.. Nice write up.

How many miles on the bike or how long in time period that I have to do the coolant change. I did not see it mention in the manual service maybe I over look. thanks
This is my question also.. How often would you have to do this?

I've found that any garage will take it free of charge if you drop it off at night when nobody is looking :icon_susp
Not to hijack this thread, but this is also a great tip. I have found a similar savings with trash disposal.. Convenience stores have big 'ole dumpsters to drop off your stuff after hours. But some locations have camera's, so just be sure to get your "Uni-bomber" hoodie snugged up pretty good and tighten up the velcro on your tenny shoes first.... (I'll try to do a write up with pic's next time I'm out doing a late night dumpster dash... :D )

Thanks for the excellent how to post. If anyone out there has RH Dooleys be ready for some extra work with the crossover pipe and the ignition switch. Worth all the extra work and I got her done.
