I'll take a look later but you will probably find they are blocked. Much better to pull the bottom hose off and let the water gush out, helps remove built up sludge in the rad.
First one is on the bottom hose radiator stub
Looking up from under the front of the van
Second one is on the passenger side of the block, halfway down behind the exhaust down pipe.
Here expertly highlighted to show up against Bonnies grotty engine.
Thanks so much panky! I’ll give that a try tomorrow and will take the pipe off to give it a good flush, bit of a tight squeeze in there with the screw driver for the jubilee clip! helpful to know where the drains are for future reference
