EtherEg Posted August 27, 2009 Report Share Posted August 27, 2009 I have a 98 gsxr and it overheats...I have a problem after driving for a little while, it will rise to around 178-205 ish driving, but if i sit at a light for long it might reach 210ish, then go down when i take off.if i then park my bike or sit on it for more than a minute or so, it will rise to 220ish and up to 235, the bike will start leaking coolant out of the overflow, and the overflow will be full of boiling coolant.I didnt hear my fan turn on, maybe a fuse? or ECT is bad? or bad wire? but am not sure if its my fan since the bike seems to climb while im riding pretty quick, (because my friends 02 and 97 gsxrs arent at the same heat as mine, they are usually 5-10 deg lower.Thanks for any helpEthan Quote Link to comment Share on other sites More sharing options...
gixxie750 Posted August 27, 2009 Report Share Posted August 27, 2009 Have u changed the coolent recently? The fan should kick on around 220 range and 235 is border on motor damge if it keeps happening. Check ur fan by plugin it in to a 12volt batt and see if it works.

EtherEg Posted August 27, 2009 Author Report Share Posted August 27, 2009 (edited) ive heard the fan kick on once since ive owned the bike, but i didn't hear it when the temp rose the past 2 times this happenedi shut it off right when i saw it reach the high tempNo i haven't changed the coolant lately, its bright green, not dirty, so i assumed it was previously done since ive owned it 3 months so far Edited August 27, 2009 by EtherEg Quote Link to comment Share on other sites More sharing options...
jermattak Posted August 27, 2009 Report Share Posted August 27, 2009 run it on a battery like brandon said, changer your coolant if it does work and see if that helps...either way, i would recommend modding up a manual fan switch Quote Link to comment Share on other sites More sharing options...
EtherEg Posted August 27, 2009 Author Report Share Posted August 27, 2009 So you think a manual fan switch would fix my problem? i was going to do this anyways, but didn't know if it were water pump, or thermostat going out?As far a coolant do i use anything special or just good old ethylene glycol, (green stuff) 50/50 Quote Link to comment Share on other sites More sharing options...
Tonik Posted August 27, 2009 Report Share Posted August 27, 2009 Gotta be a thermal switch on it that is supposed to kick the fan on. Find it (screwed into the radiator somewhere) and turn the key on and ground the wire that is hooked to it. That should start the fan. If it doesn't then you have a bad fan or fuse or wiring to the fan. If it does start the fan you have a bad thermal switch or a low coolant issue. If you have to pull the switch you will be changing your coolant, which as the other folks said is a good idea at this point. Quote Link to comment Share on other sites More sharing options...
Kahooli Posted August 27, 2009 Report Share Posted August 27, 2009 warping of the mating surface between the head and the cylinders could cause this as well. Quote Link to comment Share on other sites More sharing options...
Cheech Posted August 28, 2009 Report Share Posted August 28, 2009 So you think a manual fan switch would fix my problem? i was going to do this anyways, but didn't know if it were water pump, or thermostat going out?As far a coolant do i use anything special or just good old ethylene glycol, (green stuff) 50/50I've heard a product called water wetter works great for coolant. Not sure of the mix, but definitely look into it. Quote Link to comment Share on other sites More sharing options...
gixxie750 Posted August 28, 2009 Report Share Posted August 28, 2009 Water wetter is greatfor the motor! It however will freez and destroy your motor. If the head is warped look for antifreeze in the oil or the overflow bottle will bubble while motor is running cold. It could be a couple things,but its all very simple to do yourself. PM me if u want to call and ask anything. Quote Link to comment Share on other sites More sharing options...
EtherEg Posted August 28, 2009 Author Report Share Posted August 28, 2009 theres no trace of oil in the coolant, or a bad head gasket it ran today and when to 225 fan kicked on, and then dropped to 216 and fan went off, but once i saw my fan worked i turned it off to make sure it wouldnt overheat while it was sitting, with me checking the Coolant temp sensor, and fan Quote Link to comment Share on other sites More sharing options...

Catman Posted August 29, 2009 Report Share Posted August 29, 2009 Check your overflow tank and make sure the return hose isn't clogged. Sometimes there is sludge in there and wouln't let the coolant return to the rad. Quote Link to comment Share on other sites More sharing options...
EtherEg Posted December 4, 2009 Author Report Share Posted December 4, 2009 sound right>?was riding the other night and temp gets to 220ish when im at stop lights or have it ideling, or moving slow it will be in the 200 range, (with high 30deg weather) Quote Link to comment Share on other sites More sharing options...
magifesq Posted December 11, 2009 Report Share Posted December 11, 2009 Perhaps the thermostat is the culprit? Quote Link to comment Share on other sites More sharing options...
oldschoolsdime92 Posted December 11, 2009 Report Share Posted December 11, 2009 ^ what pops said. I would drain it and put new in. Get it to the proper level, and that way you know the mix is right and the right amount is there. and start there, expessially if your fan is kicking on.
