Modern Vespa

Hi Guys,
I have a 300cc IE LT mp3.
My fan kicks in alot more than it used to is it posible to add coolent to the radiator system?

tes and also bleed the air out

Are you certain that it is actually low? I have never had to add any coolant to mine. And while I do not know where your coolant reservoir is, mine is on the dashboard underneath a small cover.

If you do have to add coolan- there has to be a reason. Either it boiled out- or you may have a leak. Also how old is the scooter and coolant?.

thanks Guys for your replies.
Hi Maksor where is the bleed nipple? and how do I test it?
The scot is less than 2 years old and only done 3500 miles on the clock.
Hi FentonFred, don't know where my reservoir is.

"Boiling out" would be the result of a leak, no?

Boiling out could be a result of a stuck/bad thermostat, or the cap could be defective. Get the scooter up to temp, then put a piece of cardboard under to see if any leaks. If you have access to an IR non-contact thermometer check the temp at the radiator, the cyl head where the coolant hoses connect. You are looking for 195-210deg. F. The fan should come on at approx 190-195deg. F. Anything higher than 220 deg. F , I would look for "why". It would be running that hot. ( restricted air flow@radiator), possible poor flow @ water pump, stuck thermostat, other issues. DO NOT open the rad cap when hot- you could get severely burned!!!. You can buy a non-contact Infra-red therometer from Harbor Freight for $ 20-30.

today I put about 3 cups of a 50% to 50% mix of deionised water with antifreeze in the expansion chamber which is located to the left of the speedometer under a small flap. Also the colour of residue inside the cap and mouth of the chamber is orange / red. looks like I have a big problem, unless that the colour of the original mix. I will have to speak to the shop where I bought the trike.

My coolant is also a pinky colour.

Different types of anti freeze have different colours. The instructions on the bottle I have say that different types should not be mixed.

+ 1 on not mixing coolant. There are too may variations of additives. A Qt from a Vespa shop should not be much more than $8.00 Just be sure it is/says recommended for Vespa,Piaggio. Your yr model etc. If possible use a sringe with a small piece of hose to evtract some of the coolant from the radiator (cold only-don't get burned). Take it to a couple of M/C dealers for opinion. If it looks like rusty water-not good. And remember if you have a total refill use only the correct stuff for Vespa/Piaggio. If it comes concentrated-dilute ONLY with distilled water (50 cents/gal @ Wal-mart) mix 50/50.
