Radiator drain plug

[benjmer66]

Hi all 

I am having a go at changing the coolant and the van i have a citroen berlingo 1998 DW engine has a radiator drain plug, but i can't seem to see it anywhere, has anyone got any idea where it could be hidden ?

Many thanks for your help

May not have one - removing the bottom hose is the alternative option.

Hi, thanks 

the bottom hose is literally impossible to remove as you have no room to pull it off as there is something in the way looks like the chassis, is there any other way you know of ? Thanks 

Kind regards

There's probably a drain plug on the block (somewhere...), but this won't drain all of the coolant in the system.  If you want to strengthen the anti-freeze mix that you have in the system then draining off the coolant at the thermostat housing will allow you to top up with fresh anti-freeze, but clearly won't remove all of the existing coolant.
I have a cheap antifreeze tester and simply keep the coolant in place and top up for winter. 
Bleeding the system afterwards can be a bit of a pain after any draining.

I guess there are different radiators fitted but the 2001 Dw8 I'm working on has a radiator drain plug on the N/S bottom corner. This isn't the original radiator though.

Hi thanks for the reply 

Have you got a picture of what the drain plug looks like

You can't really miss it on this one if you look at the bottom corner on the passenger side, I guess yours must not have one or be different. I just went outside and had a look at other options for draining the system. Failing taking the bottom hose off there is a small diameter hose that goes from the bottom o/s corner of radiator where the bottom hose is to the oil cooler (where oil filter is) if this was disconnected at the oil cooler and lowered I think it would be nearly as good.

This is what the drain plug looks like, N/S lower corner, with a fitting to add a plastic pipe. However mine has, I think, been broken as it probably should have a paddle tap, as per the top bleed on the R/H side of the rad, and there's now just a stump in the hole!

Mine looks exactly like that on the bottom, but there is no tap, it just seems blocked off, how do you drain yours if you were to ?

Yes the tap on radiator is not very good. I think to open it you turn quarter turn then pull it out a bit. The one on this car is parged up with thread tape to seal it.
