Today dawned with some time to get started on the cooling system overhaul.
Drained the old blue coolant out and removed the old radiator - stain visible;
Then I set about some of the other pipework. I've been following tuonokid's excellent thread where he mentioned that the water block below the coil pack seems to be a common weeping point, so I removed the pipework and found this crusty mess;
Took quite a bit to remove it all from that and the other tail! All cleaned up and then reconnected.
Next I moved on to the thermostat housing took a bit of effort with the aux belt tensioner but got there in the end. Replaced the old thermostat - the seal was pretty knarled up;
And replaced the housing and bolted the alternator back up.
I also removed the heater control valve to purge the old coolant from the heater matrix. I found the best way was to attach a length of hose into the hose to the matrix and put a catch pot under the other matrix pipe. Then you just blow the old coolant out, attach a funnel to the length of hose and refill, rinse and repeat until the water comes out clear.
Then it was a case of putting on the new radiator and filling the system up. It all went pretty well and it's piece of mind to see the correct coolant in the reservoir;
All done, bled, took most of the day but pleased with the result!
I seem to have another issue though which may actually be the power-steering leak that bodger-garage mentioned. It's along the front of car slightly to the right behind the bumper. It's thin oily stuff and stops soon after the engine stops. Anyone know if this is the power-steering line and, if so, what's involved with fixing it?
