I knew this was low when I got the car (had to top up with what I had to hand, which was water), so best thing to do is drain the radiator, use a rad flush, and replace the coolant, right?
Oh my god, this has turned into the biggest P.I.T.A I have ever come across in something that is supposed to be a pinacle of engineering.
There's no drain point. Manual suggests to remove the bottom hose. EVERY hose clip is rusted solid. Ok, so take the radiator out. I sheared a couple of hose clips trying to undo them. No problem, I can replace with stainless jubilee clips anyway.
Finally get the radiator mostly out, but the only way of removing the bottom hose is to cut it in half. Joy.
Here's what came out:
Not good.
I took apart the rad cowling. One of the captive nuts in the rad had broken free, another bolt was seized in place, so I decided to cut it free with an angle grinder. At this point, I'd made the decision to get a new radiator and hoses anyway.
Here's the state of the thermostat housing:
Ordered a new one of those as well.
While I was in the strip-down mood, I also took off the fan and water pump pulley, along with a P clip that holds the heater hose in place, and the brackets for the engine shield.
At work, I made good use of the shot blaster by stripping everything back to bare metal.
I then gave everything a coat of etch primer, a coat of grey primer, and then several coats of gloss black.
Forgot to take pics of the finished pieces
