I've had to replace the rad on my 2010 ZX6R9P.
Using the Official Kwak service manual I have done the following:
Slowly filled the rad to the neck.
Filled the reserve tank to full mark.
Run the engine with the rad cap removed.
Initially I got small bubbles.
Then coolant started coming out of the filler neck faster.
I gave all the hoses a good tap to dislodge bubbles.
Then the level dropped back down and coolant couldn't be seen in through the filler neck. I assumed that meant a large air bubble had worked its way out. In the meantime the level in the reserve tank had gone up by nearly 1". I was summed that was just coming through the overflow take off on the rad cap neck.
I topped up the rad, and ran the engine again, and coolant started coming out of the neck faster than before. When this seemed to get worse I stopped the engine. Again I can't see coolant through the rad cap neck.
I can't poor the coolant in much slower, so I'm wondering ...
Is this normal?
Get hold of a Haynes manual - they'll help you out.
:rofl:
is the temperature coming up as normal?
let it cool down again then with all the rubber hoses give them a good squeeze, to push air out, top up the rad and run the engine up to temp (keep a close eye on the temp) the allow it to cool down again then check levels if all ok take it out for a short bimble and then check levels again.
Thanks Moz. I ended up with a Kwak manual. It's quite heavy. A lot heavier than a Haynes. I reckon it would hurt quite a lot if you accidentally hit your head on it. Feel free to pop over some time and I'll show it to you. ;-)
Thanks Green. At least it sounds like I'm going in the right direction.
Come to think of it, I think only 1.5L of coolant has gone in so far and the system is supposed to hold 2.5L, so that's a bit of a clue to how much air is in there!
Is there a bleed valve at the Water Pump...failing that loosening a hose to allow air out and water in.
I put a large funnel in the in the rad inlet so you are increasing the capacity of the "open" radiator and run the bike until it starts to overfill the funnel, stop the engine, let it cool and start again...........
Also as Alzo said, look for bleed holes.
