I knew I had a minor coolant leak. It started just after I fitted and sealed up my new water pump which was leaking badly.
All was fine then I noticed a few drops each day on the floor. I suspected it could be core plug or oil cooler hoses or bottom of thermo housing.
Took air filter housing off and found the a big cor plug that looks deteriorated looking damp and leaking.
In this pic it's just above the flywheel/gearbox:
Here is a closeup:
It's partially covered by the flywheel. but there is a recess I think I can use to take it out and replace a new one.
Anyone had this before and if so, what's the best method here?
Shame as I have only recently put new type d coolant in :(
