Prestone 50/50 for dirt bikes

Recommended Posts

what bike ?

personally i run engine ice , bike has never boiled over since i started running it . evan's coolant is also a good coolant .

if you do run prestone buy pre-mix or if you mix it yourself buy distilled water , don't use tap water in your dirt bike .

again from personal experience prestone eats some yamaha water pumps .

im yet to replace the water pump on my 03 450 , maybe i just don't ride enough .

thats a pretty good price , its probably more then double that up in canada . if i found it for 5.99 i think all my vehicles might get a coolant change .

My dad just bought a jug from autozone yesterday (he missed the sale) and it cost him $12.71 so thats one heck of a deal they had on that stuff. And i called my friend an ediot for buying 10 jugs...

I work at a Radiator shop.The Prestone stuff is based on Dexcool. I would not run any Dexcool or Dexclone in anything I own. Any coolant that says long life or Any color, any car is a Dexclone.

When Dex goes bad it destroys everything that it touches and GM just lost a lawsuit over the stuff.

I've used Prestone 50/50 in my last 3 bikes with no problems. $8.99 gallon with a $3 rebate at the Wal Mart. Not going to be in my bike for anywhere near 5 years/100,000 miles so no worries about any Dexcool issues.

Works for me.:lol:

Ok, I've been around cars, bikes, and radiators for a few days now myself and figure there's a little more to the story of those pictures (the second one is a battery after all:smirk: ) than Prestone anti-freeze, but..

Since your in the business, if not Prestone, what do you recommend?

I was told to avoid DEX-Sludge at all costs and to also avoid coolants with silicates in it, which suposedly will eat water pump seals?

The other thing to keep in mind is that some of these coolants DO NOT offer freeze protection so if you live in a colder climate beware...

I did a little reasearch and found out that the long life toyota coolant (red colour) was fairly well suited for bikes and i am trying that since i always have some around, (2 older POS cars) so its free for the takin..

I recomend regular green antifreeze. Nothing long life or any car any color. Don't have to buy the MC stuff thats $9 a qt at the dealer.

A-Zone has it in their Valucraft line.

PB has it as Proline.

Csk has it... http://shop.oreillyauto.com/ProductDetail.aspx?MfrCode=ORY&MfrPartNumber=GAL&CategoryCode=3219

Mix it 50/50 with DISTILLED water and change it every 2 years.

Naw that rumor is overated. My 1990 KLR250 is still on it's original WP seal using Silicated coolant. The swap to non silicated coolant started around 1996 with the move to long life coolants.

Before that all coolants except for toyota Red was silicated and water pumps last just as long with or W/O Silicates.

Silicates are basically sand yes. But they are so microscopic that it's a non issue and Silicates are a great protector for Aluminum parts.

OK, I'll check O'Reilly's stuff out. I've used Wal Mart's house brand green anti- freeze (not 50/50) in the truck and other cars for a lot of years now with no problems. The Prestone 50/50 never stays in the bike for more than a year anyway before being drained for one reason or another and replaced with new.

the walmart brand universal coolant rocks! cheap, mixes w/ any color, is the best bang for the buck. if using the concentrate then mix 50/50 w/ distilled water. change bike coolant at least every 150hrs, no matter what. and you won't have any coolant issues in any climate.

The WM stuff is a Dexclone.:lol:

Any car, any color or Long life is a Dexclone or Dexcool.

the additive concentrations are much less then whats in dexcruel, frequent changes, (defeats the purpose:bonk: ) are the key, the lubricating additives are the only advantage of the whole mess otherwise its acidic, abrasive stuff ITS THE COOLANT OF THE FUTURE :lol:
