KY 1.7 Engine in 1985 model

[steveo9007]

OK so i took ownership of 1985 model a week ago, on buying Autosleeper the seller notified me that the engine had been changed from original 1.9 petrol to what is in their now, i checked this when i got home by referencing the engine code on block beginning with KY (KY 1.7cc), anyway i took it away camping on the bank holiday, everything seemed ok(temp reading in normal area, oil light going out when running, electrics all working and starting up ok, with the exception of a slight squeal from the Alternator belt. Getting back i went to check my levels in the engine and was having a look around and notice that i only have one belt fitted from engine crank pulley to alternator, this goes around the water pump swell.

Question i am asking is that should it have one belt for Alternator and one belt for the water pumps the pulley wheels on them have double tracks on them for both belts. I have looked around the web and i can get alt belt and water pump belt. Just wanting some confirmation for this type of engine as i also know this engine is not as common as most.

Thanks for any help given.

yep one belt is correct

Thanks Gary for confirmation.

The benefit being that you get instant notification that the belt has failed with the alternator light coming on, so you know your coolant has stopped being circulated and is about to overheat. With the two belt, if the water pump belt fails, you only know when it overheats.

But of course preventive checking should also be routine...

Thanks Roger for the tip, much appreciated. I will travel with a spare Alt belt aswell.
