I changed my clutch springs and decided to change my coolant over to Engine Ice. What is the proper precedure to refill it? Do I need to flush it?

 

Jmann, the procedure isn't all that difficult. By yourself a gallon of 50/50 mix and start filling the radiator. Go slow as you'll see the hicups as you fill. You'll get to the top of the radiator a couple of times. then it wont take anymore. Leave the cap off and start the bike. The level should drop. Turn the bike off and then refill to the top. Cap the system and then move to your overflow/res. bottle and make sure that it is at the MAX line. Once you run your bike and the thermostat opens, if any coolant is needed (it wont be much) it will take it from the res. and you'll still be within the safe operating lines.

Not that difficult. I've built probably 60 atv motors over the last 2 years and I've NEVER had a problem.

Good Luck

 

I was reading another thread that Mudinuri started, he said the manual stated:

Do I need to do this? BTW, I already bought engine ice, do I need to flush the system before I add the engine ice?

 

They say that Engine Ice doesn't mix well with 50/50 mix. I would flush it out. But that is me.

 

And how would I do this? Sorry for the newbie question, just never messed with radiators before.

 

I think it would be as easy as taking off the bottom radiator hose and putting a garden hose on the top and turn it on and flushing it out like that for just the radiator. You said that you have a friend with the shop mannual, then just follow that, and you shouldn't go wrong. If you don't have one, then send me a private message, and I can email you from there and help coach you there.

 

I always ran it 50/50 with Anti-freeze in my race car with no problems. I did see a trick on there website engineice about using vinegar to clean system. Never heard of that before but sounds like a goo idea.

(from website)
How often do I need to change it and are there any special requirements?

Most every coolant product will work best when changed somewhat regularly…at minimum, we’d recommend once a year.

For racing applications, we actually recommend twice per year. The cleaner you can keep your cooling system and the fresher you can keep a fluid, the better it will perform.

There are no special requirements for using Engine Ice.

For any coolant and anytime you are changing coolant, we recommend a simple solution of distilled water and white distilled vinegar, both available at your local grocery store.

1. Mix the water/vinegar at 50/50

2. Fill system with the solution

3. Run engine until warm

4. Let cool

5. Drain

6. Run clear water through to rinse out vinegar.

7. Fill with coolant of choice.


This is the same as cleaning your coffee maker. The vinegar is acidic enough to clean out and contaminants and residual coolants, yet it won’t harm your seals and gaskets

 

the shop manual refill procedure

- remove fan sensor on top of the thermostat housing
- fill radiator until fluid comes out of fan sensor hole
- install fan sensor
- fill rad until full
- run engine
- check rad fluid level, add if needed

 

Missed the Engine Ice thing... but definitely get that out. The lower radiator hose off and a garden hose on low will do just fine.

As far as the top sensor goes... you guys are making it to hard on yourself. But if the manual says it.... feel free.

Not flaming just trying to make it easy on ya.

 

According to the manufacturer of Engine Ice, it will react with traditional coolents and cause it to gel.
I switched over several years ago and followed the flushing directions others have mentioned.
I drained, filled w/ distilled water and ran the motor. Did this several times until I was confindent that I had all the old coolent out.
Filled with Engine Ice and have never had an overtemp problem.
You can drain most of the coolent by loosening the lower Allen Head Screw on the water pump housing (where the coolent hose enters the motor). Be careful if you remove this screw as it has a crush washer on it.
