Happy Tuesday! I went out to my new-to-me F-Type this morning and was greeted with a low coolant warning. It was an unseasonably cold morning here in California ( low 30s ). I decided not to drive the Jaguar just in case, and jumped in the Land Rover Discovery 5, also got a low coolant warning which I've never had before on that car in over 60k miles of driving.

Is this just a huge coincidence? Or are these cars sensitive to this warning when the outside temperture drops a lot?

Regardless, I'll check the coolant levels tonight ( didn't have a chance this morning as I was running late for work ). I'm hoping to pick up some coolant for the F-Type on the way home from work...is there anything I can buy from Autozone / O'Reileys / somewhereelse that is the correct coolant for a 2016 F-Type V6 S? I'd like to get it back on the road asap.

Thanks as always!

 

You can use any coolant that meets JLR specification, such as DexCool. Just make sure you don't mix different types to avoid the coolant gelling.

Check your vehicle's Owner's Manual for the correct coolant/antifreeze type and concentration for your location.

 

Thanks for your help.

In case anyone here in the USA finds themselves in a simialr spot I found this at NAPA autoparts that perfectly matches the OEM coolant spec.

The coolant was super low ( see below )...seems unlikely it was this low without a leak of some description. I filled it back up to the MAX level and will see what happens next...

 

Be extremely cautious. There are several coolant pipes and the thermostat housing which are well known to fracture. One of my pals suffered hydro-loc catastrophic engine failure when coolant spewed perfectly into his air intake system. It was only a SC V6 in an XF so he was able to source a salvage engine at $8000 plus shipping, plus installation, and so much more. We in F-Types will be hit much harder.

I casually tell everyone I meet to never pour coolant into a Jag or LR built prior to 2020. Just exit and wait for a tow. Sure, a tow will cost, but it's only 3 digits.

Seriously, if you see or smell anything coolant like, anywhere near your engine, you should discon the batt and haul it in for repairs.

It is very difficult to spot the cracked pipes while the cracks are still small. Once it is fully split, the only thing left to do is cry.

 

These two cars may have coolant pipes made of the same material. I found the new parts from Jag are made of a different polymer, and some are also redesigned. They fail due the polymer characteristics are not sufficient for a 10-year lifespan in this application.

I'd guess that if both engines have the same materials, and they were both exposed to the same environmental challenge, then both could certainly fail due to the same cause, the same day the cause was encountered.

 

If you aren't checking the coolant level every week then you have no frame of reference. It could have been going low for some time and only just now hit the mark that registers with the level sensor.

 

Yes no need for expensive "dealer" coolant! It's just plain ol Dex-Cool that you can get anywhere.
