Gilera sp02 cooling oil

Post by mari0 » Sat Feb 08, 2014 2:31 pm

Hello!
My name is Mario, and I come from Slovenia. I have gilera sp02. It's in a very bad condition, so I've decided to fix it. And now I have one question, and many problems :lol: I don't know which oil is good for cooling? Can I use the one that I have for mixing with fuel, or is some special oil for that? Thanks! In a few days I'll put some pictures of my "project" :mrgreen:

Is this a mistake in translation or some confusion ;)
Usually you will have to use *water* for the cooling system.
Mixed with some kind of alcohol to prevent freezing.

A second place to put in oil (beside the engine itself) is the gearbox.

It's not a mistake... I got this gielra from my friend, and it was in a very bad condition. There is a one small white tank under the fuel tank . My friend wrote on that tank something like that: cooling oil/oil for radiator . Now I don't know if that is right or not . That white tank, is connected to the radiator . usualy, as far as I know, you put water in. So now I'm really confused :mrgreen:
Thanks
And here is a photo of that tank:

that's the compensation reservoir for the cooling system.
When your system ist full of liquid and you heat your engine up, the liquid expands.
The inner lid oft he radiator opens and the amount of liquid which is to much flows to the reservoir.
Cooling down sucks the liquid back, so the colling system always is full.

For cooling systems you should use water (some swear on distillated water). Not oil!
To prevent this from freezing (and destroing your engine) you should mix some cooling fluid in.
Here we call it 'Glysantin'. It's some kind of alcohol (Monoethylenglykol).
This one is from BASF, but you can also use something cheaper from other brands.

The cooling system of your Gilera should have about 1,1 liter of volume.
Take care that you fill up this amount.
Air locks in the cooling system may end up in a sized engine :(

I thought it was strange to use oil here, and that sticker confused me a lot. So i decided to ask :D Because as I said, that was very strange to me.
Thanks again! ;)
