Screamin_Demon Posted December 6, 2003 Report Share Posted December 6, 2003 My little cousin caused my stock impellor to warp, and eventually sheer pieces off last christmas while riding... (don't ask). I replaced it with a ProDesign proflow billet impellor. I noticed at first it wasn't making as much noise as it used to since the billet impellor wasn't making contact with anything, but I also noticed that my coolant bottle, which was moved up front, was spewing over more, and would barely have any coolant left after the engine had cooled off. I got to thinking this past week about it. What's bugging me is the fact that it seems to run hotter than it did before. Could this be because the coolant is flowing quicker, and it's not spending enough time in the radiator to cool off? Or might there be another reason for it seeming to run hotter? This isn't a major issue or anything, just a thought i've have on my mind for about a week or two... just want to see some other people's opinions and thoughts on this mod.

Nightrider Posted December 6, 2003 Report Share Posted December 6, 2003 Are any of the pieces trapped in the cooling system? Is your radiator cap in good working condition,It should hold a certain Psi before it opens and allow coolant to escape to the overflow.

. Posted December 6, 2003 Report Share Posted December 6, 2003 correct me if i'm wrong, but I believe your aftermarket is supposed to flow slower, to dissipate more heat into the coolant, and go through the radiator slower to get rid of it. Do you notice your coolant bubbling after riding it hard? If he heated up your impeller to the point of warping or whatever, chances are he coulda fried one of the o-rings and its pressurizing your coolant.

raxen Posted December 6, 2003 Report Share Posted December 6, 2003 The pro design impellers are setup to have a larger mass flow rate but a smaller coolant output velocity due to the different blade angles. Quote Link to comment Share on other sites More sharing options...

I took everything off... radiator, hoses ( except one that wouldn't come loose for the world ), and flushed everything out with water, and started fresh with new coolant. I monitored the coolant afterwards, and didn't notice anything in it... looked clean. Within a month, I flushed the system again after a few rides. As far as I now, the cap seems to be in working order. correct me if i'm wrong, but I believe your aftermarket is supposed to flow slower, to dissipate more heat into the coolant, and go through the radiator slower to get rid of it. Do you notice your coolant bubbling after riding it hard? If he heated up your impeller to the point of warping or whatever, chances are he coulda fried one of the o-rings and its pressurizing your coolant. I could see how that could be a possibility. The coolant would bubble out at first, but then once I stopped and it cooled for a bit, it'd take whatever coolant was in the bottle back into the radiator, but it wouldn't leave much in the bottle. I'd checke the level in the radiator, and it'd be near the top. What brought this question up is that I had to add coolant to the radiator itself a few days ago. It's been fine since everything happened last christmas. I didn't think about any of the seals or o-rings. It'll probably be 6 months or more before I could tear into it again and check it out.

SCOTT PRESSLEY Posted December 7, 2003 Report Share Posted December 7, 2003 I got the same impeller in mine,the bottle is not been moved yet but I have fount out that if I fill the overflow bottle to the max line it will spew, leave it at half way between the low and max and it is fine no spewage.Just a thought,if every thing is working right.

. Posted December 7, 2003 Report Share Posted December 7, 2003 Reason I say it is that my buddy blew a head gasket on his 250R and it would just keep pushing coolant into his overflow bottle until that overflowed. Last winter I took it into deep ass snow, overheated it, fried an innner o-ring and it started pressurizing my coolant. From then on whenever I'd ride it really hard my coolant would sound like it was boiling, or my 4wheeler was overheating. It was actually just the pressure being added to the coolant system. I replaced the orings and now its fine. I check the coolant in my radiator all the time, and in the overflow bottle it likes to sit with just a little bit in it, and when it heats up it fills up to add more line, and cools back down to just a little in it. It's weird, if I add some up to the fill line when its cold, or up to the full line when its hot (should still have plenty of room considering where it fills up to when its hot) it'll overflow it the next time I ride it and go back to where it was. Figure that one out Quote Link to comment Share on other sites More sharing options...
dirtclod20 Posted December 8, 2003 Report Share Posted December 8, 2003 What is the o-ring that you replaced. My banshee is always boiling and doing just as you described yours used too. I'd love to get this fixed, b/c I'm always afraid I'm going to burn up my motor. All the details you can give the better. Thanks Quote Link to comment Share on other sites More sharing options...
. Posted December 8, 2003 Report Share Posted December 8, 2003 just replace them all, its the ones on the domes that are doing it. You have an aftermarket head right? Quote Link to comment Share on other sites More sharing options...
dirtclod20 Posted December 8, 2003 Report Share Posted December 8, 2003 Now right now I just have the stock head. Quote Link to comment Share on other sites More sharing options...
fixitrod Posted December 8, 2003 Report Share Posted December 8, 2003 Now right now I just have the stock head. Try this first. It fixed my problem.... the same you are having... Click here. Screamin, as far as your trouble, maybe the tolerance on the billet isn't as tight on the waterpump housing as it should be. Is there exceptional wear in the housing. A pump need to have a tight tolerance to work properly. Quote Link to comment Share on other sites More sharing options...

Is there exceptional wear in the housing. A pump need to have a tight tolerance to work properly. As far as I can remember when I swapped them, there wasn't any wear on the housing itself. It was smooth, no ridges or grooves from anything rubbing on it. That was last winter... so I could be remembering wrong. Quote Link to comment Share on other sites More sharing options...
dirtclod20 Posted December 9, 2003 Report Share Posted December 9, 2003 I've had this done for quite some time. I'm planning on the DIY temp gauge and I'll see how hot it's getting. Until then, I'm still seeking solutions. Marc Quote Link to comment Share on other sites More sharing options...

Figure that one out I have to agree. Maybe you need to pop the head off and put a new head gasket on. It's only $10 - $15. Re-torque to 20ft/lbs and see what happens. Also, like said above, make sure you don't over-fill it. Quote Link to comment Share on other sites More sharing options...
