Please help me.my Yamaha Vino 50 Engine Cooler Cooling Radiator is dry when I check during cleaning.Do i need to put water because i have water already in the small container where i always do top up

SOURCE: Radiator fan doesn't always turn on when engine gets hot

check fuses #25 and #6 (both 30 amp)
the fan thermostat is on the left side of the rad.
turn the ignition on, and after pulling back the boot, short across the two terminal with a screwdriver.

if the fan runs, fan and wiring are both good.

if it only runs when thermoswitch is shorted like this, switch needs to be replaced (get the low temp switch to prevent overheating - your temp gauge will not go over the middle position even on the hottest days; also get a low temp thermostat,and ALWAYS get a Saab stat, not an after market!)

if the fan doesn't run when switch is shorted, check for valtage between green wire and ground at the switch.

Voltage indicates faulty fan, if no voltage then check the fan relay J in the main fuse box.

SOURCE: I have intermittant overheating problems with my

Ronnie this soun ds like the thermostat is not opening all the time. this is an easy fix. the part probably cost about 8-15 dollars at autozone, dont forget to get the gasket also.
1-2 dollars. The guy at the counter can show you where it goes

SOURCE: draining radiator coolant

IF it was really dirty before empying the old coolant - you should do a flush before re-fill with the new collant.. You can get it at any local parts store.. Follow the directions..
IF SO - I highly recomend Lucas prduct.. More money - but really good stuff.

If it was not too bad - yes - run some water therough it..

Allways do 50/50.. If you use too much coolant - you risk the cooant gelling..

Also - there should be a Lucus pruduct that is a coolent additive and is also a great lubricant for the system and water pump - to make it last longer..

Please dont forget to rate well ;o)
