Hello I'm new. 

I've recently bought a Zil 131 and its a lot of fun. 

Its developed a rattle I think around the radiator or one of the belts and cannot discern where its coming from. It's also got a coolant heating temp light showing. 

Little film of the rattle here: https://wetransfer.com/downloads/8d5d596c3fa1978e324e6e820801ea3820180311133300/3f32dc095852be75256cf1827022380b20180311133300/dbeca7 

Any thoughts or help would be gratefully received. 

Thanks 

Will

While I can see why you’re worried from the video, my experience of Zils is the only bit not rattling is the steering wheel (while you are holding it).

Does the rattle sound as soon as the ignition is turned on, or does the coolant warning come on when you turn on the ignition and stay on when the engine starts? Trying to work out if the tempratue warning is wrong  because you know it is on when the engine is cold having just started. That would suggest a wiring fault or the temprature sensor is not working. Stupid as it sounds, try putting a bit of butter or margarine under the fan belt, see if that stops it temporaily.

if the noise is there when cranking it over why not remove the fan belt then if it disappears  it has to be one of the items not turning also does the radiator have a cowl once we found that the cowl had come loose and caused it to rattle only a sugestion

We found this in the end. Not what we were expecting at all. 

We began by removing section by section anything that could be rotating - water pump, fan belt and so on. When this was fruitless we determined it was coming from the engine. We took the carburettor off when looking down into the engine there was a rod that had used to drive the mechanical fuel pump. 

At some stage it must have bounced out of its slot started to rattle about. Problem solved.
