I've got a coolant leak from the hose that goes from the left hand side of the heater matrix when you look at the engine, to the connection to the engine under the thermostat housing. It could be just the hose clamp but I was thinking I might change the hose as well to be sure. There are no other hoses connected to this one so I was wondering, can I just buy a length of hose the correct diameter and route it from A to B or should I buy a hose that is formed in the right shape? If I have to buy a shaped hose is there a way of getting a part number so that I can shop around on the net?

If you can get a hand to it, give it a wipe down with a damp rag, there may well be a part number printed on it.  Phone cameras are handy for reading part numbers from places you can't get a line of sight at.

Heater hoses tend to be ¾"/20mm ID but can't guarantee that'll be the case here. If the run is reasonably straight you may be OK with a length of non-shape-formed hose.

The parts diagrams in ETKA for coolant hoses are usually pretty vague, but if you can supply your engine code and year of manufacture of the car, I can show you the relevant diagram on 7zap.com.

Hi Wino, thanks for that. I looked at 7zap.com and found the engine. It is a 1.6 litre AVU. I rang a few motor depots but they didn't seem to be able to help. I then rang a Skoda dealer who sent me this link which is the same as 7zap  https://www.partslink24.com/vwag/skoda_parts/illustration-mailing.action?mode=K0LWRGBGB&lang=en-GB

 

They said I needed assembly number 19 shown at the top left near the expansion bottle. Price £117 plus VAT. I'm going to see what I can do. The leak is coming from the connection at the thermostat end so I am looking at just cutting the hose back by about 25mm and reconnecting it with a new clamp. The other alternative is to buy a metre of 20mm hose and try and route it without kinking it.

Well worth trying.
