I recently replaced water pump and seal after I noticed that my '02 CRF450R was spilling coolant on easy trail rides. After the water pump swap (which was successful), I noticed the same problem. It's interesting - the bike only spits coolant (I mean a LOT of coolant) after passing anything above 1/2 throttle. The bike makes this weird 'gurgling' noise, like trying to suck through a straw when your glass is almost empty. This is weird because I properly bled/ burped the radiators with coolant, and filled them to normal operating levels. The coolant spills through overflow hose.
anyways - I swapped the radiator because I thought maybe the bike was running hot. I purchased oversized radiators, bought a 1.6 radiator cap (with a temp gauge) and bought engine ice. The bike runs very very cool - the temp gauge allows me to see this. Still, the bike shoots coolant out of the overflow after going above half throttle, making the same weird gurgling noise when it does. Bike has all of its power, top end was replaced not too long ago.
I'm lost and don't know what is wrong with the cooling system in my bike. How do I make the bike stop shooting out coolant, and stop making the weird gurgle noise??? Any advice would help me!!! Thank you!
I live here in Iowa so the winters can get down to -25 or so and the summer heat can sometimes get to 115 degrees. What Anti-freeze would you recomend to put in my bike? Do any of you use Engine Ice? Im thinking about buying a jug. I also just bought this bike so im not sure what anit-freeze he has in it.
Alright so i tried poking around to find a thread on this but couldnt find one.... Swear I saw one before or you'd think there would be. So the Coolant "Engine Ice"...The guy I bought my bike from had it in, and my brother just bought one who also had it in. It claims to be some good stuff... BUT i hear whole lots of horror stories about it, about how it has less lubricant in it and its really bad for your water pump, and that it heats up much faster when you're stationary. So I drained it, ran two loads of standard 50/50 prestone in it to wash out all the old crap, and use prestone 50/50 currently. what scares me is a little dripped on my driveway, and where it streamed down the cement it left these really hard black clump deposits here and there on the cement. sometimes see little black flakes floating around the radiator. IDK if its dirt or corrosion.
So my question would be, For anyone with Engine ice experience, What do you think of it? And might I have a little Radiator issue or is this normal or should I flush it? Thanks a ton guys!
NOTE: I already know the prestone is fine. Ran it in my last bikes and for all summer in this one. Bike is a 2008 YZ250F
What coolant should I use if neither of these? Want my bike as cool & safe as possible
This has been on a thread before but I wanted peoples thoughts on a bike already built with an overflow such as a WR450. I couldn't find much tested data of actual temp changes/improvments at idle or on the move. Has anyone out there done any testing on their own? I see more of a benefit for bikes without an overflow due to fluid loss from puking it out.
