long life coolant test results

Well, I just completed a long term study in the use of long life 5
year engine coolant using my trusty 97 VFR750 as a test subject. I
changed the coolant to the long life stuff way back in October of
2000, just before I moved to Los Angeles and haven't touched it
since. Today I decided it was time to drain it and see what it
looked like. I have heard horror stories about it turning and
causing massive problems internally. I was pleasantly surprised when
I pulled the drain plug when it came out orange and clear just like
the day I put it in. I was surprised because when I put it in, I
didn't bother to do a proper flush, I just drained the green stuff
and replaced it with the orange stuff. I did however, use distilled
water to attain my 50/50 mix. So, I'm gonna do the same thing again
and I shouldn't have to think about the coolant until the bike dies
as I've got 90,000+ miles on it and it is my only form of motorized
transportation. I've never had an sort of overheating problems and
it has never run hot. Even stuck in traffic for long periods the
needle never got more than a hair above halfway. Sure the radiator
fan ran constantly, but the bike never came close to over heating.
And this was in 100+ degree weather. So, to all that have had a bad
experience with the orange long life engine coolants, I'm sorry to
hear it. The only thing I can see as being a problem is using tap
water, which has many impurities in it, that probably reacted with
the orange stuff causing the problem.

So, use distilled water and use the orange stuff and forget about it
for 5 years.

No problem man.

Good to know!

How many miles did you cover in that time?

I have done many long term coolant and oil tests. I've always just
called it being lazy. It's nice to know now that I was being scientific. BTW I've
never seen any damage traceable to these tests other than the damage to my
parts suppliers bottom line, and the damage to my credibility when the "true
believers" find out I'm a heathen.

VFR Doods:

I changed to the 5 year orange coolant formula in my 2000 VFR nearly three
years ago (summer of 2003) when the original T-stat stuck open @ 14,000
miles.

If you do make the switch to the Orange 5 year formula, make sure the
formula does not contain silicates. Silicates can erode cooling system
components.

The Prestone brand stuff I got is silicate and phosphate free. Use
Distilled Water to achieve the 50/50 mix and you'll be in like flint - it
contains less contaminants than tap water.... A quick flush-a-roo with the
cylinder and waterpump drain bolts out is not a bad idea.

I too can attest to the "orange stuff" I changed to Texaco Havoline Dexcool mixed 50/50 w/distilled water in 2000. I only kept it in for three years though. Second change in 2003 and due again next month. Close to 148,000 miles on the two coolant changes and excellent results. Never had a overheating problem and has the original water pump.
I'm a happy camper and will continue to use it.
