Hi, I've just fired my car up for the first time this year and she ran well apart from their was coolant leaking from the top water neck, you'll have to tilt your head when looking at the picture, I did replace the thermostat about 6 months ago, but I don't think I've started her since, anyone know what it could be? ( I've got red coolant and its a new radiator. )Is there a gasket in this spot? And should I have replaced it when I changed the thermostat? Anyone know a part number?

Any help is appreciated.

Thanks

Yes mate. There is two small o rings there. Easily break if you remove the neck and will cause a leak like that.

 

I had one of the two break on me when I removed that pipe.

 

Only a few quid from MrT but don't have the part number to hand.
