Default rm125 coolant.....?

     

its a 99 rm 125, and my coolant is a little dirty, (brownish)......and im looking for a place to drain it but im not really sure where?...i searched already and is there suppose to be a water pump on the right side i can drain from?...where is it?...................also about getting it back in, do i just pour it in, and will it just work its way threw the engine and push out any air?......sorry for dumb questions ive never replaced coolant on a bike before...just cars.

Yes on the right hand side look for where the water hose comes out of the engine. You might need a manual to find the right bolt to remove on your bike. My drain looks the same as the rest of the bolts. Once you find it and drain your old fluid refill the radiator to the top let it run till it's warm. After its cooled ALL the way down you could recheck to see if it's needs to be topped off, mine never does.

usually it's the bottom bolt on the water pump cover, it *should* have a copper washer on it. always always always remember to tighten all the bolts and hoses! i've lost lots of coolant from forgetting to tighten a radiator hose enough and it pushes out.... also, when you get the new coolant in, tip the bike really far to the left and to the right, to get any air bubbles that might be trapped out. then re-check the level, start the bike, and the bubbles should be worked out of the system

becareful when tighten that little bolt because you can either strip it out or twist it off.

Also make sure you use bike antifreeze and not car antifreeze. Care antifreeze contains silicates that will damage your waterpump seal and also phosphorus is bad for your radiators.

I use either Maxxima or Artic Cat for around $7.00 a gallon already mixed. Takes about 1.5 quarts.
