africa twin - in africa - over heating!? please help
First advise is….STOP
…. The may be nothing wrong with your bike the gain there might be.
All things at the moment seem water related. If there has been a gush of water and steam from your overflow you may very well have a blocked radiator and these needs to be serviced immediately if that is the case.
Low temperature may be that there is no water around the temp sender unit …..running bike without water is not good for it.
…Stop it is time for maintenance all machinery needs it you don’t need to blow up another bike. Servicing may not include the removal of and cleaning of the radiator 199to 2010 is 15 years and the radiator my not have been removed in 15 years
In the spirit of trying to be of help to you I would suggest the following
The interoperation of extreme heat conditions should be interoperated as though the bike were in heavy traffic conditions stop start traffic or on the other hand the climbing of high mountains put the engine under extreme load or working conditions and causes friction … heat!!!
In your e-mail you say on the way down the temp gauge stuck on 0 for 500k
Did you not go up the mountain first and perhaps the engine overheated and disgorged (threw up) out the overflow. How often do you check the water?
On the way down does that mean from UK to Morocco????
Your bike is water cooled so water surrounds the cylinders and head to keep the bike cool
This is what I would do:-
·Importantly the radiator must be working properly and the fins must not be blocked externally by mud or other contaminants.
·The internal part of your radiator must not be blocked one and one only blocked tube can cause overheating. It is a small radiator …. …..Take the radiator to a radiator specialist and have it cleaned.
·Now the fan switch this must be working properly as you the driver can not take the place of the sender/sensor unit and turn the fan on and off when the engine requires it. the fan will turn on automatically when the engine reaches a required temperature the fan will turn off when the engine cools to the right temperature.
·To Check if the temp gauge is working properly obtain an aftermarket temp gauge that can be fitted to the bike and do so this is not meant to replace the gauge that you have but is a piece of test equipment to check all is going well
- Firstly check the engine oil and see if there is any water in the oil: check by draining a small amount of oil from the drain plug…..If it is milky then you may need some other answers. Water nay be keaking into your engineThrough a head gasket or crack I certainly hope not.
- The coling system is very importantv to the running of your bike
- Yes by all means remove and check the thermostat …. If it is jammed open this should be obvious the top part will be raised from the bottom part not so bad except to get your bikre to correct operating temp
- it can be jammed closed as well…….this can cause overheating which is not good
- Test… Place in boiling water and observe that the thermostat opens if not …. It is an important part to keep your engine operating at the correct temperature; if your engine is not operating at the correct temperature then it will cause problems
In all fairness to your great Africa Twin do the servicing procedures before you continue and let us all know the outcome? If you’re not sure take the bike to a mechanic or ask questions on the HU site there are some people here with a lot of experience and you can judge for yourself.
NB…..After you have drained any water from the bike flush the engine part wit a hose of high pressure to wash out any scale or junk that has accumulated in the water jacket and when all is back together refill the cooling system with a good quality recommended inhibitor/anti corrosion and anti freeze if in extremly cold conditions
Low power at altitude is kinda normal
But overheating is not
Thanks for the opportunity of being able to help and look forward to your reported outcome
