Good morning.

By revealing myself as being very senior citizen, and probably not the only one, who loves his 'pocket rocket' as much as I do, there are only so many things I can do myself. What I would like to do is to completely drain the system of all the now very murky water. Keep running clean water through it till I'm satisfied. Then finally replace the cap. Is draining the system and refilling a job I could have a go at or get someone else to do. Be honest. I won't mind.

Hi,

It's easy enough. I'd recommend getting a bottle of rad flush and put that to work first.

Use a hose pipe to flush in the opposite direction to normal flow

If you're lucky there will be a drain plug at the bottom front corner of the radiator. If not the other way to drain the radiator is to remove the lower hose from the bottom rear of the radiator. 

 

I would try and disconnect the heater matrix and radiator and flush them through both directions separately. You don't want all the chunky bits ending up stuck in the cores

To drain the system I usually disconnect the bottom hose from the water pump end, and the heater matrix

Thank you!

A challenge but I'll have a go over the weekend.

There's also a Drain Plug on the back of the Engine Block (unless you have a late SPI / MPI Block), it's up near the Clutch Slave, around the back.

 

While this will allow for draining of the Block (unless the Block is choked up), it is too high to drain the entire Cooling System. When Draining the System as you are considering, I remove this one and the one from under the Radiator (if fitted).
