Draining Radiator

[Cyril]

Help!
Wanting to drain the radiator to renew anti freeze but it I cannot find the draining tap on it or neither on the block?
Could there be another point of drainage?
There is a nut screw at the bottom right side of the radiator (as your facing the engine), could this be the drain point?

That should be the drain plug. The block plug is under the manifold towards the rear of the engine.

Danger Danger !! Don't touch the drain c0ck/nut on the radiator! And the block one is likely not worth worrying about (probably blocked with silt). Just pull the bottom hose off the water pump and let it run.

That's me told!

Thanks Folks

[bmcecosse]

Just because - it is VERY easy to rip the tap (better not refer to c0ck again ) or the drain plug, out of the radiator when attempting to open it......

LOL
Just managed to do it as you suggested no problem.

Also... (just in case you are not aware) advisable to only use the old original 'Blue' stuff ( Ethylene Glycol) for the Morris Minor cooling system.

Why?

[les]

I've heard similar things regarding the unsuitability of this 'new' 5 year life antifreeze, can't fully recall the reasons behind it, but just in case and so as I don't have to think about it anymore I use the blue stuff!

[bmcecosse]

Only 5 year life??

[Cyril]

The bluecol I bought wasn't blue in colour, but it stated that its Ethlene Glycol

[Cyril]

Jeeeez Mark motors back to the garage to buy the correct ant-freeze and do it all over again
Seriously though, thanks for the advice. This forum has been worth its weight in gold!

Why?

"Long life" (often stated as up to 6 years!!) OK and specified for the modern trend of 'new fangled' plastic radiators and modern spec robot built engines apparently.
It is convincingly argued that this O.A.T "Organic Acid Technology" based liquid (orange and red ) primarily eats away at old style radiators, particularly those with various types metal soldered joints and other older style metals within older engines. The leaving in the radiator for this extended period is also a temptation with this new technology fluid rather than the absolute maximum recommended changing of every two years for the Morris Minor .
(I for one would rather stick to the original comparitavely safer non invasive blue glycol stuff myself !)

Many years ago I remember exciting 'colour change' anti freeze was introduced - started off yellow - if it changed to red you needed a new engine....
