Fuel Cooler
Just been under our defender and noticed a slight drip from the fuel cooler..... it's the coolent pipe (orange fluid) that pushes on I presume?

Question is will it need a new one ? I'm not sure if I remove it if I'm going to loose all the coolant, or can new connections be purchased

Best

If you clean the surrounding area and then unplug it, you will drain approximately 6 l of coolant. You can catch it in a clean container and reuse it if it is in good condition.
Before doing that I would try to figure out where from exactly it is leaking, once drained that’s a bit harder unless you can see something obvious.

You will loose almost all of your coolant as that’s the recommended drain point for a coolant change.

Edit - Johan got there before me Very Happy

Hi.

Looks like it's weeping from the push connection. Pipe looks ok, seems to be pushed on ok , unless it's worn and needs to be a tighter fit

You can always take it off quickly and refit, but be quick and keep a clean container present ready to put it back in if you need to.

There is indeed and incoming / outgoing fuel pipe there, and the same for coolant, as it’s coloured as you say then it’s coolant, it might just need reseating.

My guess is someone has been at it, trying to pull it off before without unclipping it properly, possibly.

Personally as a drain point I prefer the thermostat drain hose, it might not quite be the lowest point but drains faster, when I later used the cooler I found nothing there to have worried about anyway.

OAT Coolant lasts well with a very long life, so luckily not a job to have to do often.

I have Motul Autocool (orange) in mine, meets LR specs. _\Hennessey|Venom| F5/___

Most of the push type connectors seal with an o-ring and these go flat over time.
If you take the connector off and remove the o-ring you should be able to match the size. Defender Td5 Commercial 2002
