Gardner antifreeze change

[Tonyw200]

Hello All 

Can anyone help with the correct way to drain the old coolant and refill with fresh on a gardener 2 L 2 

Can i refill using a vacuum tool to prevent air locks.

 

Thankyou.

You won't get an airlock if you bleed from the screw on top of the thermostat , bleed the skin tank, and have a higher mounted header tank.

Draining will depend on how your system has been plumbed in, they are all different, you might have a drain tap , you might just have to pop a pipe.

Thankyou for your help.The antifreeze that's in the engine @ the moment is blue.Do gardeners take a certain type or can I use any that are good quality.

[matty40s]

You are best to stick with the blue one you currently use, I stick with the blue one.

Dont top up with a different one with your existing fluid,  it can clog up and form a jelly suspension if you are mixing old types. 

Most modern ones are inter changeable, so doing a complete drain of system , flush and refill will allow you to top up with most other modern coolant/Antifreeze solutions.

Your credulity is lamentably lacking. Must try harder.

 Surely "credulity" means an unwise eagerness to believe.

 Matty's unwillingness to believe is a rational position so perhaps attempting to lead him away from it is initself lamentable.

As an aside and not engine specific 

I used  some ready mixed antifreeze and it simply did not work from a corrosion protection perspective resulting in the coolant becoming brown rusty coloured.

 

I have since thoroughly flushed with water and used  concentrated coolant so I could control the coolant to water proportions.  This was recent and the results have yet to be seen after the engine has had some use.

 

The lesson learned being to avoid ready mixed coolant.

No doubt you meant TO the moderator. Accepted, of course.

just to expand on this. The anti freeze to use is Ethylene Glycol, referred to as 'IAT'. The longer lasting 'OAT' anti freeze which is usually a reddish colour provides protection for upto 5 yrs as opposed to 2yrs for the IAT (Blue). However, I've been informed in the past that OAT will not protect the brass/bronze components within the engine & will also react adversely with any IAT (Blue) anti freeze still in the system, as mentioned above cab turn to a jelly like substance. I use Morris MEG mono-ethylene glycol at a 50/50 mix for my 2LW.
