There is a tremendous amount of confusing information on what coolant to use when you change/flush your car. I went up to Ferrari/Maserati of San Diego today to buy some for my upcoming coolant exchange. They use and recommend ShellZone Pre-diluted. I believe 2 plus gallons are needed. They sell it for close to $40 /gal. I went home and ordered 3 gals from Walmart for $9,99 a gal.

I hope this helps with the confusion.

Hi there, I did search the archives when I replaced the coolant on my car, the consensus was use BMW coolant. Which I did. Yes, I did pay way more than 10 bucks. In any case the reason I did write this e-mail, there is a procedure when replacing the coolant and you should purge the system. I did find this procedure on the Maserati UK web site and followed it. One or two driving seasons later the engine appears happy

I am sure there are many good products to use. I just wanted that part of the process to be a no brainer. The parts man said when cars are delivered from Europe the coolant is blue, ShellZone is green. I believe Shell is a major sponsor of Ferrari racing.

I also read the coolant change piece from the UK. I disagree with the authors recommendation about disconnecting the lower radiator hose. The drain plug comes out very easily(14mm). It is rubberized and has a retaining clip to keep it from dropping into the pan. It is possible older cars have the drain plug problem.

Decided to take my chances with the plug and it all worked out A OK

I think it's more of a path of least resistance. If the plug comes out easily with little force, then by all means, go that route, but if you have to crank on it, and there's even a 10% chance it may break, it's best to go for the hose. This goes not just for Maserati, but any car in which a self induced radiator replacement would be tragic in comparison to, at worst case, losing an inch at the end of the lower hose.

My takeaway from this experience. Have an OBD-II reader

I like to save money as much as the next person and I get satisfaction out of being able to do some of the work myself. But the $300 I saved would have been a hollow victory had I not had an OBD-II reader and the software on my iPhone. After sailing through the coolant exchange, bringing the coolant up to temperature with the heater on a couple of times I shut the car off and buttoned everything up. I started the car and the engine light stayed on and the car would not shift in to gear. I recycled power to the car and the same thing happened. Sinking feeling started here. My OBD-II with DashCommand said I had two error codes, P-1670 and P-0460. The first had a worthless explanation and the second was a fuel sensor error. Since I was no where near the fuel sensors I cleared the codes. Engine light went out and the car ran perfectly.

The BMW coolant is blue. Easy way to tell if a BMW or BMW based Range Rover was kept up to snuff if whether the coolant is still blue... Costs more than the green stuff.

I used blue BMW coolant when I did my Heater Core Bypass.

The color of coolant is not an indicator of the quality...It s just a dye..BMW, Land Rover Etc...do not make coolant...They will put it in a gallon jug and charge you like 50.00 bucks for it along with their emblem...All the universal stuff from the auto parts store will work fine..If you want a particular color the Pentosin will work as well...

Agreed, the color of the coolant can drive you nuts but it doesn't always tell you the spec or quality of the fluid. In any case, we offer factory spec coolant in our service kits we sell it on it's own as well. Feel free to reach out if you need anything, always happy to help!

Best Regards,

Questions:
Can the BWM coolant be mixed into factory Maserati coolant (2015 Quattroporte)?

Is that BMW "Gray" coolant actually blue that every-one relate to? I see that BMW made a green one for the 2018+ models as well?

Did any-one used the Audi Antigel Coolant (G13) on Maserati?

They are both in the list of best coolants:


This articles describes various types of coolants and why you do not mix different types (doesn't mention Maserati once though )) )

Bro, drop some phosphate-free coolant in that bad boy.... if it's concentrated, mix 50/50 with distilled water and call it a day.
