Coolant?
Permalink  
 


Hi,


I've just bought a 04 DTRE, never had a bike before and my mechanical knowledge is comparable to that of a small blind child.  My bike came with no manual or instructions either so I'm in a bit of a predicament.


I've found the 2 stroke oil reservoir, but on the other side of the bike is a smaller reservoir.... I've read up on it as much as possible and think it's for coolant.  If it is, should I use pure water or do I need to mix it with something?  If it's for something else, what is it?


Any other tips or things I need to know would also be greatly appreciated.  Thank you!

Sounds to me like you're describing the coolant expansion tank. It should max and min levels on it. Provided the system is full (engine been run then when cooled if you remove the radiator cap it's full), you should top up the expansion tank to the max mark using a solution of water and antifreeze/summer coolant which you can get at any garage or hellfrauds etc.

the coolant expansion tank is the small plastic one under the seat/seat pannel

never had to touch mine, but im sure i read in the haynes manual it said the level had to be in the middle of the min and max lines,not filled up to max

you should check the manual

also...as i should check mine tomorrow, whats the ratio of water/anti freeze to mix ? is it just normal car antifreeze ?

im just gonna check mine in a min, do you ever change the radiator coolant/topp that up ?

ive never even opened the cap on mine, the temp gage never goes above half way odd so presume all is well, but just wonderd what intervals it should be changed or topped up or whatever ?

i think the one under the seat is an expansion chamber, - ie it pump excess coolant in to there or something , im not 100% sure !

how do you know what the rad level is at and if it needs topping up ?

Just drained and refilled my cooling system 50/50, (distiled water if you live in a hard water arear as I do)

Make sure you get coolant/antifreeze for an aluminium engine.
