The coolant seemed to be requiring to be topped up rather more often than usual and I just assumed it was caused by the hotter weather as summer here is on the way. So I noticed the drain out cock looked a bit grotty and it’s hard to clean and service it while the radiator is in place, so I pulled the radiator out and found that there was nothing wrong with the cock and no radiator leaks. Reinstalled the radiator and refilled with coolant and then noticed a green flood heading towards the garage door. Turns out the thread in the block for the smaller bolt for the coolant inlet had failed so there was only one bolt holding the outlet on. There is enough metal to thread the hole out to 3/8 whitworth but questionable as to how long it might last. My question is how any member who has had this problem has carried out a repair and whether anyone has used the Metalock process as a solution?
