GSF250 Bandit coolant and misc.

[Lissa]

I am not mechanically minded at all, so please bear with me. Just need some questions answered, that no one seems to be able to answer for me. Wasp.. help??

I just got a GSF250 Bandit not all that long ago. I know how to do simple maintence checks such as tyre pressure, checking brake fluid, oil, chain.... but I have no idea how or where to put the coolant, or to even check the coolant. If anyone could help me that would be great. You can pm me if you like.

Also I am reving the bike at about 11000 rpm on average, and wanted to know if that is suitable for this bike.

Thanks

Melissa

I think, if its like it's big brothers the 1200 & 600, that it doesn't have any coolant other than it's oil. They are Air/Oil cooled having lightly finned head an block combined with an oil cooler (radiator).
If eleven grand is less than the red line then...go on enjoy yerself..

From memory, they red line at 16000... 11k is no worries, in fact they like it! I thought they are air cooled too...

Just got this out of Wikepedia;

All engines are DOHC inline four with 16 valves. 600, 650, 750 and 1200 models employ SACS (Suzuki Advanced Cooling System) cooling that is combined air-cooled and oil-cooled; these engines are derived from older GSX-R models, either sleeved-down from the 750 (apart from the 750 itself, obviously) or bored-out from the 1100. The 250 and 400cc models are water-cooled.

and this site has all the guff on them too.

So it looks like it could be liquid cooled..? Dunno where you stick the coolant though..?

Ok... I dont care if I sound like a noob.. but do you have to put water in the radiator?

When I look at the specifications for a GSF250 it says..
Engine oil
SAE 10W/40, API SE or SF
Change: 2,700 ml
Filter change: 3,000 ml
Overhaul: 3,400 ml
Coolant including
Reserve tank: 150-250 ml
Engine: 1,700 ml

So I dont have to add any special coolant at all?

Yea red line is about 1400rpm... I dont red line it much

Thanks

Yea I know they like being revved high, just wanted to make sure they had a limit... well thats red lining I suppose.

Yup I change my mind, it is liquid cooled . Possibly under the seat or somewhere near the radiator..

More Info:

Suzuki Bandit 250 (GSF250) Naked commuter / semi sporty thing. Two main types the GJ74A model (early nineties to 95 I think) and the GJ77A model 96 - present. All models up to 1999 are gray imports in Aus. The GJ77A model comes with optional variable exhaust valve timing to boost midrange. You can tell these models by the red cam cover and the distinctive noise when 10,000 rpm is hit. All 250 bandits sold by Suzuki domestically have the variable valve timing. The engine is derived from the GSXR250 inline water-cooled 4cyl, 4 stroke. Engine parts are not interchangeable with the Across. Engine produces ~ 40 ps at ~14,500 (can't remember the exact peak but redline on mine is ~ 15,500). The GJ74A weighs around 156 kg and the GJ77A weighs 147 kg. GJ74A has 14 +3.4 L tank and GJ77A has 15 + 3.4 tank. Both have single front disc. Yellow is the best color and gets plenty of comments (all good) both from drivers and riders.

Very definitely liquid cooled, Lissa. The 250 Bandit motor is more advanced than the bigger ones, until the 1250 came out recently. My wife had one from new, but I can't remember where the coolant header tank is. If I happen to see a 250, I'll have a look for you, failing that, try the local Suzuki dealer, they should be able to point you in the right direction. Bloody awesome little bike

[Lissa]

Thanks for that guys. I think it must be under the seat or something like you said terbang, cant see where else it could be.. there doesnt seem to be anything near the radiator. I will take it into the local Suzuki Dealer sometime and get them to show me, as I cant find anything on the net about it.

Cheers!!
