Good morning,
I have to top up the radiator fluid of my x-type 2.5 V6, from 2001! Should I take the original liquid or not?
What equivalent can I get? Thanks

 

Batman9393, in short, there are 3 kinds of coolant out there right now. You have green, orange, and a pink/red coolant. They are all different and protect the coolant system in various ways. Unfortunately, the colors are not really interchangeable. So, I would look at your overflow bottle and see what color you have. Most of these coolants are good for 10 years, 150K miles (250,000 KM). So, if it has been awhile since you replaced the coolant in your car, it may be advisable to simply do a complete drain, flush, and refill. That way you can make sure you get the same coolant in the car. If you do the drain, flush, and refill, then you can fill with whatever color coolant you want. But, if you know that the coolant has been recently changed, then going with the same color is about the only thing you can do.

Of note, coolant comes in 2 styles. You have 50/50 mixes and you have the concentrates. The 50/50 mixes you can pour straight into the car. No extra steps are needed. If you get the concentrate (will say on the front of the bottle), then you have to add equal amounts of coolant and water (highly recommended to add distilled water, but you can add distilled, spring, or tap) to get back to a 50/50 mix. I mention the water. While you may think water is water and what is the big difference, ask some of the guys that have had to replace their radiators. Distilled water is 100% water with nothing extra in it. When you get into spring water and tap water, there are certain chemicals that are still in the water (chlorine, flouride, salts, etc) and when you add these to the coolant and then add heat on top, it can cause reactions with other metals. Due to the radiator being aluminum, it is the "weaker" metal for interactions and it will get eaten/rust/corrode first. This leads to holes and in general, problems.

If you have more questions, please ask.

 

Specification: WSS M97B44 Extended Life Coolant (usually coloured orange)
Concentration: 50%
Frost Protection: -40°C (-40°F)
Change Interval: 5 years or 156,000 miles

I found both the concentrate and the 50/50 at an Advance Auto store. I DID NOT rely on asking a store worker but, read the specifications printed on the bottle myself to ensure I got the correct speced fluid.
