Running hot in reservoir - 1996 kawasaki VN 750 Vulcan

water and coolant mix is wrong

You must have a coolant leak. If there are no signs of a leak, you may have a gasket on the engine that has gone bad, and the coolant is being pushed out the exhaust system. The coolant expands when hot and cools when the engine cools. During the cooling stage the cooling system creates a suction on the coolant in the reservoir and draws enough coolant back into the system to keep it full. Apparently you are loosing enough coolant somewhere that the reservoir can not fill the system before going dry.

Here are the instructions to de-scale your Cuisinart SS-700, taken directly from the unit's manual, available here (www.cuisinart.com/share/pdf/manuals/ss-700.pdf):

1. Empty the reservoir.

2. Disable the AUTO OFF and OFF TIME features.

3. Making sure there is no K-Cup in the brewing chamber, fill the reservoir with 60 oz. of undiluted white vinegar.

4. Place a large mug on the drip tray and run a Hot Water cycle. Select the 12 oz. brew size. Discard contents of mug.

5. Repeat the hot water process until ADD WATER is displayed on the control panel and the reservoir lights will flash.

6. Let the Brewer stand for at least four hours while still on.

7. Rinse the water reservoir thoroughly and fill with fresh water.

8. Run another Hot Water cycle. Discard contents of large mug.

9. Repeat hot water process until ADD WATER is displayed on the control panel and the reservoir lights will flash.

10. You may need to perform additional Hot Water cycles if you detect any residual vinegar taste.

Note: If DE-SCALE is still displayed on the control panel after completing the procedure, repeat the de-scaling procedure above.

How do you know it gets hot? Are you going by the temperature gauge on the dash? Or have you checked under the hood and found out the engine really is running hot? ...Reason I ask is, something just doesn't sound right in your description. After just 5 minutes from starting and driving away, the engine would not yet be at normal operating temperature. That would explain the heater not yet warm. But the temp. gauge says hot?
If so, I would replace the temperature sending unit on the engine. the one for the dash gauge, and see if that was the problem-not reading the temp. accurately.
Couple of other things: Are you sure you got all the air out of the coolant system? Start the car with the radiator cap off and let it run until the engine is warmed up fully, then shut it off and install the cap. Does your reservoir tank stay about half full where it should be, between the full-hot and full-cold marks?
If your problem persists. I would have the coolant system pressure tested, and see if you could get a true temperature reading of the coolant when it seems to be running hot.
Good luck.

This can be caused by an insufficient coolant (aka antifreeze) level. Look at the coolant level in the reservoir under the hood. There should be two marks on the bottle "warm" or "hot" and "cool" or "cold". If the engine has been running for a while as in the case when the car has been driven few miles, the coolant level should be up to the "warm" or "hot" line on the bottle. If the car has been parked without the engine running for a couple of hours or more, the coolant level should be at the "cool" or "cold" line on the bottle.

Never remove the radiator cap when hot or if the engine has only been been stopped for less than 2 or 3 hours.

If the hot coolant is at a level that is below the warm or hot line, you should add more of the coolant / water mixture only to the reservoir - not to the radiator. If you are only able to check the coolant level when it is hot - you will have to repeat this procedure until the coolant level of the reservoir is maintained. Checking the hot coolant level can only be done when it has been allowed to cool between hot checks. The cooling period is the only time when coolant is drawn from the reservoir back into the radiator.

If the cold coolant is at a level below the cool or cold line of the reservoir you should add more of the coolant / water mixture to the reservoir and to the radiator, too. Fill the radiator to the top of the neck where the tube from the reservoir connects to it.

If you're still having widely fluctuating temperatures while driving at normal operating speeds, there may be a problem with the water pump, thermostat or other portion of the cooling system.

I hope this helps & good luck!

The black rubber hose may be bad and needs replaced. This hose should connect to the radiator at the radiator cap and run along the firewall to the coolant reservoir. Also the coolant reservoir might be cracked and leaking on to the rubber hose, if this is the cause just replace the coolant reservoir which may be a dealer only item, check at you local auto parts store and they will tell you if it is a dealer only item. If you have to replace the coolant reservoir, make sure the car has not been run and the coolant at the radiator is cool, cause when the engine is hot the hot coolant runs into the coolant reservoir till it cools and returns to the radiator when engine is turned off and cools.

Assuming that it's used in an open-air spot so that the intake air is cool, hot compressed air means the head is running hot.

Most small-to-mid sized compressors run warm after a few minutes, and some run fairly hot after 10 minutes.
If the hose is too hot to hold after 20 minutes, the first suspect is friction within the compressor's head.
This could be caused by poor circulation due to a low-quality oil.
It could also mean a blockage in the air-delivery system (ie: oil-dust gunk at a fitting causing restriction, making the motor work harder than normal.

Flush the oil reservoir, pull the feed lines one-at-a-time and flush out. Pull the intake filter and blow out the head & valves.
Refill the reservoir with Craftsman compressor oil.

check your radiator cap seal for damage, because it can let the coolant to enter the reservoir at low pressure

take the rediator cap off and add water there...

you need to have a pressure check don on the radiator. this will pinpoint the leak if you dont see any leaks externally it could be a head gasket or a manifold gasket but the simplest thing to check is the thermostat. it may stuck in the close position and not letting you antifreeze circulate
