Coolant on side panels
on: September 21, 2020, 04:31:39 AM
Hi everyone

Ive fairly recently acquired a 2015 s1000r

So far riding has been excellent, but Ive noticed that on a couple of occasions when going slow speeds through town the engine gets quite hot - dash says 103-105 degrees celcius, temperature goes down again when riding at more speed. 
When I get home there is coolant spray on the side panels and hoses near the coolant overflow tank.
The coolant overflow tank level is good, and the radiator level seems normal.
 
Is this a normal occurrence? or is there something deeper to investigate?

Thanks

Well, you're in Australia, right?

The problem is obvious.  Your bike is upside down.

 221 F temperature for my non metric friends. Is that normal temp?

In traffic temperatures can soar.

Since I live in a similar climate as you - seeing high coolant temps is normal.
Personally I wished I was able to program the fan to come on earlier.

The fan should come on just over 100 or so, and then it will climb to around 105-107 if it is really hot.
It should stabilise and then come down once you start moving again.

As for coolant coming out - that is not normal.
However, if the expansion tank is not at its normalised level it will do this.
So after it has gotten really hot in traffic with some good heat soak - check the expansion tank once everything has cooled down.
If the level is visible through the sight, just leave it be and check it every now and then.

If the tank is dry I would do a check on the cap and maybe do a pressure test for peace of mind.
I got nothing.....

That year bike (I used to own one) has a vent hole in the top of the coolant overflow tank. Not a hose to the ground or up in the air. A kit was make to change the tank so it had a vent nipple that a hose could be attached to and taken about 150mm vertical. (or you could put a longer hose on it and go to ground, but does not seem to be needed.) Many people fixed the problem by inserting a rubber vent hose into the hole in the tank, must fit snug, and taking it up in the air with tie wraps. A known issue.
Here is more information: Seems this was in bikes made before April 15, 2015. UK PUMA # 598542 60/02. USA service, 171150800/1713501.
Part numbers for "repair":
17 12 8 545 627 tank
61 66 7 067 184 clip fo9r hose 619500
17 13 8 562 618 support
17 13 8 562 013 exterior steam hose
Data taken from my notes of 5 years ago. Over flow tanks like this are open to the air, a pressure check would be proper on the sealed radiator system to see it the cap opens at its rated pressure. When this happens it opens to the overflow tank. In the case of a burp or boil over, that would certainly flush fluid out of the overflow tank.

Mr zzgyan

They do run hot stationary and your figures are consistent with my 2018
Your overflow tank may have been overfull and is now finding it level hence the level looks OK.
I have a later model with a drain hose
If yours is the same as mr Beech go with his suggestion would make it easier to see when you stop.
Other suggestion alter the level to half way between min & max when cold see if that fixes it.

What state?

Lucky you

And greetings from the Leper Colony.
Enjoy the AFL GF.
The bike has not moved since April, not worth the grief of being intercepted and does not do it any good with a 5km limit from home.

Stay Safe
