Anyway I've rode it a few times just locally and the light stayed off most of the time, but coming on occasionally. However I unscrewed the the oil cap to notice a creamy residual around the cap threads. I haven't drained the oil yet, but when I look through the level window it just looks black.
Are the bits in the expansion tank linked to the creaminess around the the oil cap threads....and not additive as he said? Should I be worried ...any advice welcome as when it comes to engines I'm a bit green,,,only doing basic maintenance . Any advice appreciated....

Just bought a k75s with 75,000 miles on it. On the journey home after buying the temp light stayed on most of the time.Don't ride the bike when the temperature light is on unless you are ok with ruining it.
Your bike has a cooling fan which activates when the bike is starting to overheat. The fan will come on and you will not see the light. It will run for a while then shut off. It will repeat that cycle when weather or traffic is liable to cause overheating. Look behind the radiator; that is where it is located. Get a thin dowel or rod and try to rotate it by pushing a blade. It should rotate without effort but it won't spin like a roulette wheel. If it takes effort to get it to move, you must replace it.
Flush the entire coolant system, rinse the coolant reservoir and replace the coolant. Do you have a manual? If not, you can download one from this site in the repair guidance section.
Check the oil level. Replace the oil and filter.
Welcome, wuyang. Please post up some photos of your bike.

Hi all....cheers for your replys ....the bike is k75....Righto. If it is an S, put that in the profile too.

Post pictures of the creamy residue, some times this is a sign of water in the oil. Possibly it could be due to a leaky head gasket. Until you determine what is the cause you are risking destroying the engine by riding it.

If so is this seal located on the pump when removed or the engine block behind the pump?
Cheers
Post by: Laitch on May 09, 2017, 06:53:25 PM
Could it be the oil/ water pump seal?You would see traces of a leak from the weep hole under the pump. Do you have a workshop manual?

First thing I would do is change the oil and filter as well as flush and refill the cooling system. Check the cooling fins on the radiator. On a bike as old as these bricks are, there will be a large quantity of bugs and dirt filling the spaces between the fins. All that stuff will drastically reduce the cooling of an engine that already runs hot. In an extreme case it will be necessary to remove and soak the radiator to get all that junk out.
The stuff you mentioned in the cooling is probably stop leak that the seller put in there to hide a leak, possibly a leak that put water in the oil. If you are lucky, the problem is in the pump which can be a simple bolt on replacement.
I hope you didn't pay a premium price for this bike as it looks like you are looking at a couple hundred right out of the blocks to make the bike usable. It's too bad, but it looks like you got involved with a dishonest seller. The good news in all this is that you have come to the right place to get things straightened out with the least expense and aggravation.

Rebuilding the water/oil pump appears to be very challenging task from what other have experienced in attempting this task.While I would not describe it as very challenging, it does require some mechanical skills that may be beyond regular maintenance abilities.

There is plenty of "how to" information on this site and others places for those willing to take the plunge.

A search on pump repair both here and on the net in general should prove valuable.

I do have a Haynes manual and uk motobins is not too far from where I live. I believe the pumps are £190 ish. I will enquire about the cost of a rebuild if it is motobins who do that.

I'd say that coolant and oil are coming into contact with one another, and this can only really happen at two places: (1) head gasket, or (2) pump.
One thing is for sure -- while investigating this, take heed of Laitch's advice above and do not run/ride the bike with the temperature light on.

Is that a tube of silicone on your left tragkorb? That could be Exhibit "A" in terms of investigation into the previous owner's maintenance approach.

What is the texture of those bits? Are they hard like silicone, or soft like cottage cheese?
Soft like creamy cheese and squashes like a paste.

It's hard to tell what this means until you drain the oil and have a look at it. This could be coolant stop leak, or it could be some kind of oil/coolant mixture that has made its way into the cooling system.
You mentioned that it looks black through the sight glass, but this might not tell the whole story. If you are able to drain it and take a few photos, I think the other Motobrickers here will be able to chime in on the likely culprit.
Post by: Laitch on May 10, 2017, 10:41:46 AM
Flush your coolant system; replace your coolant, replace your oil; replace your oil filter; check your fan to see if it can be rotated manually—all steps recommended repeatedly since post #3. There are other K100 repair manuals on the site you can consult if you get stalled by your Haynes.
Report back.

When the globules are pressed between your fingers what is the consistency like, does it feel oily? With a blown head gasket you would be normally seeing more than just a couple of blobs to quote Alice "this is getting curiouser and curiouser". Have you checked the water pump weep hole yet?
Regards Martin.
Post by: wuyang on May 10, 2017, 03:32:43 PM
Does your bike have a hose running from beneath the front of the fuel tank to the front top of the crankcase?
I get round to checking running short on time at minute.
Thanks wuyang
Post by: wuyang on May 10, 2017, 03:33:45 PM
Your fuel tank cap should be rotated 180º so its hinge is at the rear. As it is now, water accumulating around the perimeter of the cap can infiltrate the tank and mix with fuel. Obtain a new gasket and remount it.

What do you mean?Some oil filters have paper decals or stickers on them with the name of the filter or other information. Those need to be removed when the filter is mounted in an oil sump like it is with the K. If they aren't removed, they'll show up as clumps in the oil that people will describe a brie, mayonnaise, cream or who knows what else, based on the describer's experience with goo.

Ok.
The water inside the bottle is just like drinking water,,,,,not black....
Clear water? no coolant? If that's the case, then the white stuff is either lithium grease from the clutch splines, (haha... jokes) or more likely Stop Leak which has now blocked the radiator and/or the thermostat and/or the water pump.
The absence of coolant leads me to believe there may have been a pesky leak that was being frequently topped off with water only, or someone has already tried to flush the gunk out, or some of those products instructions say to use water only for "treatment" then drain and add coolant.
I found similar stuff in my coolant after purchasing my truck, heater barely worked so I flushed the sh!t out of it leaving a pile of white globules on the ground similar to your pic. Heater immediately improved 1000% and I was still patting myself on the back on the way to work the next morning enjoying the toastyness I had restored to the cabin. When I arrived at work and got out there was an 1/8" stream of coolant shooting straight out of the front of the grill from my radiator. PO had obviously taken shrapnel through the grill and went for the shortcut fix. Had a nice buildup of the same white stuff in and around the hole. (<---Go ahead, go crazy with the jokes) :hehehe
I would remove the fuel tank, top off the radiator at the cap, then drain the system into something I could measure how much came out. The volume and condition of what comes out will be helpful clues.

Back I the good or bad old days depending on your perspective. There were a couple of home brewed remedies for curing radiator leaks. Putting black pepper into the radiator was one. And another one, in which you poured raw egg whites into the radiator which congealed when exiting the hole closing the leak. This looks a bit like that. :dunno Does it taste like egg white?

The bike was kept out side all weathers and said any signs around the plug were maybe from the ingress of water.
Anyway I've dropped the oil this morning and it looks just like any other oil....just black no creaminess at all which surprised me. Incidentally the filter hasn't got any paper attached.....I was given on of those like cup removal tools with the bike.
I just need to flush and refill the coolant and I'm hoping it happy days. I feel like I've made a bit of a fool of myself by expecting the worse.
Post by: Martin on May 11, 2017, 04:57:11 AM
:2thumbup: You might want to find a fix the leak properly then use only distilled water and a good brand of long life coolant.
