Draining The Radiator...losing The Will!
#1
Posted 21 May 2012 - 07:42 PM
all three bolts sheared,
casing and sandwich plate WELDED together,
much pain with a lump hammer and various cautious chisels to split apart
mole gripped the remaining pins out
cleaned engine block surface,
and discovered a tone of crud inside the engine block under thermostat. Decided needed to flush radiator and water system out. Bought some rad clear kinda stuff.
However, I'm down with the whole hosepipe in the top of the radiator thing but after reading that the best way to drain the radiator/ system is to disconnect the bottom hose..
...how the bleedin do you get to it?
I can see the jubilee clip, but cant reach it, let alone the bottom hose?! I understand the long shank screwdriver to remove jubilee, but cant see how I can remove the pipe, or get it back on afterwards?!
Any help (particularly pics, because I'm not confident at this stuff) much appreciated. Thanks

Other than that a lot of patience is needed.
Hope this helps.

I removed the front grill, loosened the mounting bolt for the radiator and lifted it a little clear. After copious amounts of WD40 on the jubilee clip on the bottom hose it came off fine.
Drained, and flushed it with the garden hose,
mounted back, not entirely trusting of my replacing the bottom hose and new jubilee clip correctly -but I'm sure I'll soon find out when radiator is refilled and the rad clear stuff is added!?
Only thing is...in a few days time I've it to do all again to get the rad clear stuff out! AAARGGHHH! MINI's!!!
Cheers again guys!

Now the hose is off, and the water pump gasket replaced...how in Jeebus name do I get it reattached?
The hose doesn't seem to have any flex in it as its a one piece molding to the water pump and some where else out the back of the engine(?)
I've pulled the rad around, removed the bottom mounting bolt, its been in, its been out...but apart from various scrapes, cuts and aches absolutely nowt to show for it!
I even tried a smear of copper grease (lets face it, everything else has it on, going back in!) on the rad outlet but all to no avail. It just wont connect past the shoulder on the tube...
AAAARRRGGGHHHHHH! and Oww me bleedin forearm...

Attached hose and then fully mounted rad. Put whole lot back together (how are you meant to tension the belt by yourself?! Did me best!) and now discovered that the water pump has failed and is leaking water from there!
Gasket fitted so its not coming from there, only thought is water pump.
First name terms me and the bloke at Minispares...kinda

tension the belt by turning the pully tensioner, loosening the pully nut a tiny bit helps, and ease the tensioning nut with wd40 first. The tensioning nut is awkward, but lifting the radiator slightly and using a long extension on the ratchet (so you have the ratchet under the front of the car by the number plate, if you see what mean) make it easyer. I think the belt needs about 12mm movement in it, with reasonable pressure applied between the pully wheel, and the altinater.
have you got a haynes manual? worth getting one if not.

Well I got a new water pump, new gasket for better or worse. Did use sealant the first time but it doesnt seem to be as good as the Loctite stuff ive bought second time round from Halfords.
Trial and (mostly) error with the alternator tightening up. The belt is firm though so fingers crossed.
There's no water visibly leaking now BUT it looks like the Head Gasket has stopped being thanks to the man handling of the thermostat housing.
So its time to reach my limitations and limp it to the miraculous Mike at Miniworld Bilston. I tried me best...bit naffed off to be honest...

I have SPI and I drain the radiator by removing the grille, disconnecting the connections on the radiator fan switch at the bottom front of the radiator, removing the lock tab, some WD40 on the switch and wiggle the switch out. Out comes the coolant.
Reviving a dead thread here but re: the fan switch at the base of the radiator, how do you wiggle that switch out? It is recessed and the only grab points are the terminals? Asking before pulling!
