According to the two Tiger owners manual I have
The 2011-2014 bikes have a coolant capacity of 2.4 litres.
The 2015 and later bikes have a coolant capacity of 2.69 litres.

Triumph use HOAT spec. coolant (Hybrid Organic Acid Technology) -- 'net say:
"HOAT is an organic acid that includes silicates as additives. The silicates inhibit corrosion on the alloy parts of the engine.
HOAT coolants have a service life of five years or 150,000 miles, after which they should be flushed out.
This type of coolant is either yellow or orange."
The Ethylene Glycol part of 'permanent' anti-freeze / coolant is quite long-life -- but acids can form, over time, and it's these that can cause corrosion and affect internal parts like head gaskets.
Corrosion damaged head gasket can allow coolant to leak out, into combustion, or into engine oil.

The Triumph labeled HOAT coolant is blue. Is it necessary to change every two years? Questionable, I did it because I needed something to do to pass the sequestered time.

Just changed my coolant as per instructions on the Muddy Sump video below

Thought i would update this link - as my coolant in my 2012 Tiger  had not been changed since new - so 8.5 years !
Came out clear & not discoloured at all.
Good job to do though during lockdown - ready for the spring.
You can order Triumph HD4X coolant on EBay for around £10 per bottle  - 2 should just do it on older models, as long as you don't spill any !

Note - The Haynes manual section on how to do this as far to complicated , compared to Muddy Sump as usual !
Also a Triumph Dealer will charge you around £50 for this every 3 years.

I don't wish to be skeptical here but I find it hard to believe that there is anything you can get done at a dealer for 50BP.

 I found the price here - which is close to me in Cumbria   - as also quoted i suspect as done as part of a full service for this price too - as both front panels etc, need removing ( can be done with Engine bars & Sump guard fitted ) if you have a flexible bucket to catch the coolant.

Easy job & another task which helps you understand your own bike more  - which may serve useful at the roadside one day

However in the New world of PCP bike ownership - this probably is not the case

Only thing I ended up having difficulty with doing this myself earlier this month is the O-ring on the tube at the bottom needed replacing and I didn't notice until I had refilled it.

Then I think I overfilled the overflow cause it was leaking out of the cap for some time afterward but seems to have stopped.  Need to wait for it to warm up so I can run it with the garage door open and not kill myself.

The price for the Triumph HOAT coolant in the USA is quite high. However, I have been using Xerex G-05. https://www.valvoline.com/our-products/antifreeze-products/g-05-antifreeze-coolant as it is an HOAT coolant. Price for one gallon was $20. A gallon jug of concentrate will comfortable do two swaps at 60/40 coolant/water ratio.
