Coolant system recomendations

[german]

Tiger users,

IÌm Fixing a tiger 02 22,000 kms , it did not start, during the inspection the gasket between the Eng and fuel ejection / air body  was burned (I replaced the gasket) after this action the eng started but the eng light was on, I verify the wiring between the sensors / valves, the plus / injectors function and all was ok. When the eng was running I observant that the temp indication was very low (cold) , I verify the level of the coolant  and it was between the low and max  marcs, I removed the temp sensor without spill of coolant (no liquid in  the system) I  found an internal damage inside the sensor/thermostat/ stopper manifold.



I recommend you to verify the liquid level in sensor / stopper manifold, it has a drain port in the top, apparently we cannot trust in the reservoir indication.

Hmm, I'll get right on it, just as soon as I've worked out what all the fuss is about oil level, tyre pressure, etc. :D

Have you run the bike through three heat cycles since you put it back together? If the ECU picks up something has been disconnected while working on it it will show a fault code. Three heat cycles of the engine with no fault should put out the light. Let me know how you get on mate.

Let me comment you, yesterday I replaced some pipes in the coolant sys after this I trying to run the Eng, during this process I found a water leak from the exhaust in the low part of the system, apparently I need to replaced the head shim.



Jim, you have some technical manual of this eng?

i will appreciate if you can tell my if I can interrogate the  ECU without scanner.

[Jim S]

You said the engine light was on? I thought you meant the ECU warning light on the dash? Sorry, I've no service books as yet but I am working on that!



The ECU fault codes can only be read by the Triumph computer I'm afraid. I have found you can make up your own maps and install them using a Tuneboy.



As I've only had the Tiger for three months I'm just learning about them for now. I believe someone else on this forum has a manual though and could help you possibly?

I have a Manwell but I'm away from home for about a week.  Will certainly help then if still needed.



I like the idea of doing own maps, do keep us posted :twisted:

I just discovered the same thing in regards to the coolant.



On the way home from a two day ride yesterday I noticed the temps of the engine were quite high.  Up hovering in the 3/4 - 7/8 part of the guage.  It has never done that before.



Babied it home and looked at the overflow bottle and it showed it was full.



I pulled the tank and popped off the cap, no water visible.  I drained the system and it had water in it, but it was not full.



My best educated guess is that the cap failed.  It alowed overflow, but did not suck back in when cool.



I replaced the cap, totally flushed the cooling system, washed down the motor (it was filthy), modded the air box (another thread), and refilled with new coolant.



Runs nice and cool now.

Modded the airbox :?:

hola fiends,



Sascuash,

I recommend you to verify the thermostat case inside only you need to remove the 4 pipes, the cap, temp sensor and 2 bolts.

This manifold has an O-ring between both parts, you wont have any leak if you disarm this part.



Brother,

Thanks for your help, you can tell me which manual do you have, because I am looking the triumph service manual but I do not know if it has a repair section.



best regards.

Modded the airbox :?:

Check the modifications forum, I'll write something up shortly.

best regards.

I have the Triumph manual; very expensive so it had better be very thorough.  I won't be back home till the weekend; I'll check then.

Please find attached the damaged part.

Sasquatch, I hope you know by now that your overflow tank has the rubber hoses reversed. Factory screwup. When the overflow hose is connected to the side of the tank it will allow overflow but will not suck up fluid when the engine cools, thus wasting fluid and depleting the fluid volume in the radiator/engine. See my thread today on this subject.
