Coolant questions
It have been frequently said here to use silicate free coolant to prevent wear, particularly on the water pump. I understand this statement and agree with it. My question is: if this silicate is so much harmful on motorcycle's water pumps, why aren't they on car's units also?
Honda make a motorcycle dedicated coolant that is free of silicated but why not for their cars also?
Finally, do the coolant need to be silicated free? My motorcycle dealer have a coolant that say "low on silicate". Is Honda's totally free of it or "low" like that one?

I just went out and looked at my jug of coolant I use to top off our cars and it states silicate free. I thought the reason we needed silicate free was to prevent corrosion of the aluminum parts.

Is there a coolant WITH silicate?
I had never even thought about it. I've been using Prestone's 5 year coolant/antifreeze(the orange stuff). Just went out to the garage and found out it was silicate free.

I got to Canadian Tire store (kind of Pep Boy equivalent for you, south guys) this afternoon and found two brands that were written to be silicate and phosphate free. And both of them were labeled as being "long life" (5 years) coolant. So, Redelk, yours is probably silicate free because of its long life statement. That's all I know about coolant...

IMO, the bike anti freeze thing is kinda like the bike oil thing. Virtually all late model cars use aluminum heads and radiators. The water pump seals in all vehicles are nearly identical. I can't see why a bike needs a specific type of antifreeze. I don't doubt the new permanent or extended life antifreezes aren't better than the old green stuff although I've had the green stuff(plain ol Prestone)in one of my bikes for a few years with no problems. I'll probably switch to the new stuff next time I tear into the motor.

Alumacool is what I use. Why risk it?
