notacop Antifreeze?, we don't need no stinking antifreeze.

Slogow Notacop: Are you talking airhead or oilhead? I never could figure where to add anti-freeze in my R1100s also. LOL

It may be because replacement parts are astronomically expensive compared to the cages. My last bike had a tight clearance between the radiator & air horn I had mounted. I must have bumped it out of alignment when I removed the front wheel for a new tire install, and when I got it back together, the first big suspension compress caused the tire to catch the lip of the air horn and drive it into the radiator. I couldn't find anything used because the bike was only in production for one year, and the cheapest radiator I could find new was over $400. For my Strom, I did end up buying a non-Suzuki coolant yesterday, but only after alot of research. Oil & filter also non-OEM, but only after alot of research on those too.

DesertBike Yep, that's the usual story.

I don't get how there came to be a problem. Why on earth would those building motorcycle engines use water pump seals that were incompatible with existing engine coolants?

There sure is a lot of BS and snake oil around.

notacop Funny I never had that problem on my old Boxer Beemers.

The usual story is that once upon a time, motorcycle water pumps - specifically the mechanical seals - had a problem with coolant containing silicates as a corrosion inhibitor.

Not sure why that didn't apply to cars as well. A coolant pump is a coolant pump, isn't it? Don't know the answer to that.

The question of silicates or not is almost a non-issue today. Car-world started moving away from silicates and toward OAT (Organic Acid Technology or Organic Additive Technology, depending on who you ask) as corrosion inhibitors in coolant, as early as the 1990's. Today, there are plenty of "car" coolants that don't contain silicates and are otherwise perfectly suitable for use in motorcycles.

One local independent shop talked themselves out of any further business this way. They foisted a totally unnecessary coolant flush on me when I had the Vstrom in for a valve clearance check.

You guessed it, these so-called "professionals" insisted that "car coolant" would somehow "damage" my engine.

Of course, the owner was unable to state any specifics, when asked.

Big Boy My Experience

I was wondering about the basic Prestone Antifreeze available at the local Wally World and whether it would be Silicate Free and safe for the bike. Sent an email to Prestone Customer Service asking that very question. Here's their response below.

to me

Good Afternoon Harry,

Yes, the Prestone Extended Life 50/50 Prediluted Antifreeze/Coolant in the yellow jug is silicate-free and recommended for use in your motorcycle. Please let me know if you require anything further.

Sincerely,
Aaron Jones
