Finally, the coolant stays in the engine! Got the new plug in on Thursday, helped with a bit of sealant just in case.
I filled the coolant on Friday, having given the sealant ample time to dry. Unfortunately, having had the core plug out I’d introduced the mother of all air locks. Fortunately, I was able to use the bleed screw fitted to the old thermostat housing on the front. I filled it up but it was too late to start it (there’s a flat above my garage with a small child).
So, today, I fired it up and lo and behold – no drips! Took it for a quick drive and still no drips.
Big test Monday – Stoneleigh…
