Is Prestone Anitfreeze/coolant 50/50 solution ok for my motorcycle? It says it for light trucks and cars on the front?


Or do I need some proper motorcycle stuff?

Also, it seems a little challenging to change it, is it? Thanks.

 

Make sure on the back label that it specifically mentions it is silicate free and safe for aluminum engines; like so:


I used Prestone Extended Life.

One way to flush the system is by removing the radiator cap, then pulling off the water pump hose. Drain it, re-attach the hose (without the clamp), fill it with clean water, & drain it again. Repeat until the water comes out clear. You can use regular tap water to flush it but before the final fill, rinse it with distilled water a couple of times.



With the reservoir, disconect the hose from it that goes to the radiator, pull it through the frame/engine and hang it down. Gravity will syphon out the contents. Fill it & drain it a few times.



When re-filling the system, re-attach both hoses and clamps (snug but not too tight with the water pump one), fill it up to the radiator neck and start the engine with the cap off. Allow the engine to reach operating temperature so that it circulates the coolant around & removes any potential air pockets. Add coolant into the radiator as needed to keep it full. Once satisfied it is full, replace the cap and fill the reservoir up between the two lines.

 

how would u get to the radiator cap? remove the whole front end, right? and use a tube to get the the rad. cap

 

Although I don't think it's absolutely necessary. Removing the upper, along with the right intake resonator tube would definitely give you a lot more space to work with. After that, the cap is wide open & accessible with your hand.

 

I went ahead it did a partial job, I probably didn't drain it all but there is definitely some fresh stuff in there. Oh well. Those pictures are pretty helpful though.
