Think I may have cure it double dosage of Radweld Gold seems to have done the trick. From what I could see last night, I'm pretty certain its not core plugs. Tracing back water ascbest as I could it seemed to be coming from that block that mounts on the block/head

Hi
A pressure test is the way to check if you have an invisible leak, and if it doesn't hold pressure, you need to locate the faulty hose. If it's the waterpump, you need to check with the engine off, and you'll often find traces of a drip when cold. You'll need a VERY bright torch to find the pump ...

Getting back to the OP. It's a 2.5td. Will do the standing test tomorrow. I'm hoping it's not worst case.......,......

Seems to be roughly a litre per journey to work and back, so approximately 35 miles ?

Hey there people
I have a strange and mysterious case of coolant fluid going missing on a regular basis.
No sign of leakage anywhere, no oil in the fluid when I top up, no sign of water in the oil, etc etc.
Any ideas gratefully received
