Where's the "Coolantology" Sticky?

Oh I'll change the coolant...probably just not this weekend.

I have no factory 'destruction manual'...but think I found some instructions online...I just don't want an air bubble in one jug or something and cook a cylinder!

Thanx for the fan temp info...I'll check the lady's fan out....make sure it's functional.

I notice this bike has radiator lower grommet problems. I think a previous owner installed a cool aftermarket chrome cover...and left something off. One mount grommet is intact...however the other grommet is toast...Essentially the radiator is just hanging by the top bolt. I'll have to fabricate something as a temporary bushing until I get to a Honda dealership(about 60 miles away)

I definitely want to change mine, but I have not found a good set of instructions. Neither the Clymer manual nor the Owners manual tell you how...

Is there a resource online?

750ACE.com has a maintenance section with some instructions on coolant change.

Not exactly a Spirit...but as close as I could find online for any real info on 750 Hondas.

There is a drain bolt on the water pump itself it's on the left side of the bike right along the frame rail. But I found it much easier to just remove the hose from the pump and drain it that way. The radiator cap is under the plastic neck cover in front of the tank on the right side of the bike. You will have to take the tank bolts out and lift it/slide it back to get the plastic cover off. You don't have to remove the tank completely though. Then just fill it up and run it a bit with the cap off to burp the air out of it. It's really not hard at all, if you can change the oil, you can change the coolant.

Everything spool said..you fill it to the bottom of the neck, so that you can see it, then rock the bike from side to side, until it goes lower than you can see, a flashlight will help if you cant see, then you repeat this until the level stays up, then with the cap still off you run the engine, top up if the level drops, then blip the throttle a couple of times and top up, then while it is running check the overflow tank level with a flashlight, there should be about 1/2" or more in the overflow tank..check the level one last time, shut off the engine and top the tank up to the top of the two lines..I had to use a syphon to do my tank..

I have a VT1100c and it takes 2 litres.

If its Ethylene Glycol based coolant you are good to go. READ THE LABELs. Yes the stuff at the auto parts store or Walmart is fine. I myself buy full strength coolant and mix myself with water out of the hose. BUT, I also flush the system yearly as part of seasonal maintenance, when I could easily run the coolant for many years.
