OK here's my dilema. Now i feel pretty stupid for doing this but i had to make do with what i had. I have an 05 CBR 600RR. i went to change the oil on this thing and well....didnt have a Filter wrench to remove the filter. So i did the old fashion (Ghetto) trick of using a screwdriver and going thru the filter and cranking that thing off. Well..i did just that and unknowingly went too far when driving that thing thru and puntured the Engine Oil Cooler next to it (i know, i know.. what a dumb ***) Well 180 dollars later i replaced the engine oil cooler but now the bike is overheating. It goes up to 245 when riding and i know normal operating temp is 170-180. Does this thing need time to circulate itself? I know some coolant & oil leaked out when i replaced the Cooler but ive refilled them both. It seemed pretty straight forward replacing this thing. No leaks have been found. The O Ring inside replaced. I'm almost wondering if i received a Faulty part. If anyone has ideas - that'd great!

 

are you sure the temp gauge is on farenheit

 

My bet your problem is with your coolant. You said some leaked out, and if you refilled it with out "burping" the system air pockets will not allow the system to cool the engine properly. Run the engine so you it get up to temp like 220F, the temp the coolant should start to circulate. At that point fill the reservoir to the fill point then put the reservoir tank lid back on.

Give us an update on how this works.

 

I hope he is not seeing 245 C. That would be 473 F.

 

My bad. I should have thought before I typed. That would be a little warm wouldnt it

 

Forget about letting the engine warm up to 179C.

Here are the steps to properly fill your coolant system.

1.) Shift the transmission into neutral. Start the engine and let it idle for 2-3 minutes.
2.) Snap the throttle three to four times to bleed air from the system.
3.) Stop the engine and add collant up to the proper level if necessary. Reinstall the radiator cap.
4.) check the level of coolant in the reserve tank and fill to the upper level if it is low.

Install the radiator reserve tank cap.

 

thing is i did run it a little after installing the Engine Cooler. came back and filled the Resevoir to the Upper Level. I went and rode around the block and thats when the temp came to 245 at idle it shot to 250. The gauge even started flashing at 250. before refilling the Resevoir tank - the coolant was at the half way mark between lower and upper. Ill try your suggestion out and ill check the reserve tank again. Last time i checked after riding around the block it was still at "upper". Thanks for your help.

 

Does your cooling fan come on at around 179F ?

 

Yea it does

 

OK so i checked the coolant level again when i got home from work and it did go down halfway. Thats a good sign indicating the coolant's circulating. I filled her back up to Upper but its still shooting to 252 at idle. Im assuming since quite a lot of coolant spilled out its goin to take a few more bleedings to get this thing circulated fully (I HOPE). Ive been doing the procedure to bleed this thing so hopefully this thing will eventually start cooling down. Ill keep ya posted - thanks!
