Thread: Which hose to drain coolant?

Try and trace the hose that goes to the bottom of the radiator, I will be tackling my D3 TDV6 next weekend which looks just as painful also have rear HVAC.

I use the quick connects on the drivers side that go up to the fuel cooler. That drains pretty much everything bar the heater core. I use compressed air to blow the FBH and heater core out.

Thanks for the replies! I spent more time with the workshop manual to find a pic of the thermostat housing. I've labelled the hoses (see pic) as I think the are connected. Will have another attempt at the coolant when the weather stops crying.

Because they can. Anyone masochistic enough to own and work on a Land Rover must be competent (or stupid I suppose). Simple is for Asian makes.

Simple for sure,but also way better thought out.

LR put no thought into maintenance,maintenance costs,etc.They couldn't care less,as we all know.

There’s a small cooler hose down near the front cross member - pull that and everything will drain nicely.

Thanks Tombie. I did that (removed the quick connect from the transmssion oil cooler) but only 9.5 litres came out (with all bleeders open). I also removed the heater return pipe from the thermostat housing and that drained another 0.5 litre i.e. 10 litres total. Since the dry fill capacity is 15.9 litres (w/o rear heater) that's a lot of old coolant left behind. What did I do wrong?

I attempted to remove some of the other connections from the thermostat housing (in case some more coolant was 'behind' the closed thermostat) but I "chickened out" when I was using nearly enough force to break the plastic housing. I can't have the vehicle disabled in the driveway until the shops re-open...
