Before filling the system, I stuck a hose in the top of the radiator and removed the drain plug to try and flush as much crud out as I could

What colour was the flow ?

I broke my bucket

This is the flow out of the drain plug with the hose in the top pipe - I couldn't turn the pressure up very high because it would just blow back out the top.

I gave the bleed pipe a good blow from the rad side, and I could hear the bubbles in the expansion tank

That look like a restricted flow ...

Take the rad off and lay it flat on the floor and do the same flush ...

It was a bit rusty coloured at first, then eventually ran clear.
I'll take the rad off tomorrow - is it a pain to get out?

No it's actually quite easy, 2 bolts at the top and 2 at the bottom then it slides up and out. You need to take the fan off

Ah I was hoping to leave the fan alone. Someone before me has nicely butchered the nut on it

It should be gushing way more than that feeble drip. In my opinion

Did you remove & test the thermostat at any point ? Also it's possible to get the two smaller pipes on the wrong ports, which does affect the coolant flow.

They are slightly different sizes

I'm sure the pipe from the radiator to the expansion is correct because I can blow through it and hear bubbles, hopefully that means the other pipe is in the right place too

You disconnect from the radiator and the other end goes to the expansion filler neck. You shouldn't be blowing bubbles, it should be clear

Pardon the stupid question, but where is the bolt on the driver side of the radiator?

There's one on the passenger side (although it won't come free because the nut is spinning freely - any tips?), but I can't see one on the driver's side.
I hope I'm interpreting RAVE correctly in thinking that the mounting bolts should be on the bottom side (10):

kermit_rr · Saturday at 14:43

Maybe it's missing? Should be pretty obvious really

kermit_rr · Saturday at 14:44

Looks like the lower thermostat hose is leaking?

blue_cheese · Saturday at 14:58

I loosened the clip and pushed the hose back slightly, that's where the drip is coming from

pwood999 · Saturday at 15:07

Any leaks will cause issues because the system needs to be under pressure (about 10-15psi) to prevent the coolant boiling.

blue_cheese · Saturday at 15:48

No leaks at the moment, just loosened choses while I remove the rad

You have emptied the rad, yeah ?

Drained from the plug on the bottom

Didn't get anywhere today unfortunately, couldn't get the bolt on the rad to loosen without the nut going with it. There's always something small in the way!

Try again tomorrow

kermit_rr · Saturday at 18:50

Don't forget the hoses above the thermostat will be full of coolant

Can you get a screwdriver to lever it up with a bit of pressure while you unscrew it with a socket?

I dont think you will need to remove the fan.
-Remove both coolant pipes from the radiator and try to position the thermostat in an out of the way spot.
-Remove the top portion of the fan cowling.
-Remove the two metal clips at the top of the radiator that holds the rest of the cowling in place.
-There are two plastic pins that i have circled in blue on the bottom of the cowling that allows it to locate, lift the cowling slightly just to pull these pins out of their locating holes.
-Push the cowling back towards the rear of the car so that it hangs slightly over the fan.

-Undo these two bolts on the bottom of the radiator. But use plenty of penitrating spray because their nuts are only held in place by the plastic molding of the radiator. Ive circled them in red. Its hiding behind some plastic cover in green, Im not sure what that portion of plastic is though, it should not be there.

-Then you should be able to just lift the whole radiator out vertically, it will probably need some jiggling to get it free. Also just make sure the cowling doesnt stab a hole in it while you lifting it out.
