Hi!

Along with the 4C I also have a Jeep Renegade Trailhawk, and both cars are low on coolant. Also in both manuals they ask for coolant that meets MS.90032 standards. Looking online, it seems everyone is confused on what coolant they should use.

I've bought the Mopar 10 Year/150,000 Mile Coolant 50/50 Premixed which all sources indicate it's a OAT coolant, like the manual says. However, there is nothing in the bottle that says MS.90032 but it does say MS-12106.

I took some of the coolant that was on the Jeep and on the 4C and they are both orange. The liquid in the bottle I bought is pink. Searching for this online is yet another confusing factor. Some people say "the color indicates the grade, don't mix different colors". Other say "the color has no meaning; the factory might have a different color for their coolant"

I also looked at this catalog, and none of their coolants say it meets MS.90032. Yet both car manuals again ask for " MOPAR® Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT (Organic Additive Technology)".... *sigh*

Halp!

Thanks! :)

Just use 50/50 mix or -- if you're in a non-freeze climate -- drain it all and use a bottle of water wetter and distilled water.

Cooling systems are pretty straight forward.

I would say exactly the opposite.
Using the wrong product may cause issues.
They aren't likely doing this just for kicks and giggles. And everything these days seems over-engineered.
Whether it be for the longevity of the hoses, water pump seals, thermostat, heater core, sensor accuracy, or perhaps even lubrication, I wouldn't go against the manufacturer's recommendations unless you were in a bind and there was no option.

Hurla, is the one spec perhaps European vs N. American? I don't have any constructive answers for you, but it is a great question.

Just did a google search on MS.90032, and guess what - every other forum for Chrysler vehicles is asking the same question!
Time for a dealer to chime in.

EDIT:
Found this resource online at moparinternational.com, with US and international part numbers and specs for FCA fluids.
http://www.moparinternational.com/assets/maintenance/english/pdf/Cross_Reference_Guide_19Dec2014.pdf
My search, above, lead me to that chart, but nowhere do I see the MS.90032 specification listed.

For the MS-12106 spec coolant, it does say:
Ethylene glycol based formulation to prevent freeze-up and boil-over while inhibiting corrosion. Must not be mixed with any non-conforming antifreeze. OAT (Organic Additive Technology). Developed for newvehicle technologies.

This is perhaps why my local, convenient Dodge dealership refuses to top up coolant on my Ford and GM vehicles when I send them there for an oil change!!!

The sticker on the Trunk mentioned Petronas Paraflu. What i believe is that they mean Paraflu UP (See info below). However, it only says "MS-12106", not the MS-90032.

Not sure what to do.....



PARAFLU UP is a concentrated protective fluid for radiators. It is a Monoethylene Glycol base fluid, formulated with organic inhibitors based on O.A.T. (Organic Acid Technology). Also suitable for professional use. PARAFLU UP is a specific protective fluid for the cooling systems that contain innovative light alloy materials.

CHARACTERISTICS
Advanced stringent laboratory tests by PLI show that PARAFLU UP meets all requirements even in extreme running conditions. PARAFLU UP mixed with 50% water allows:
The maintenance of the protecting characteristics of the inhibitor agents.
Optimal heat removal from the engine combustion chamber.
The maximum protection against: - Cavitation and electrical discharge; - Freezing (down to external temperatures of -40°C); - Limescale formation; - Boiling in the warm periods, traffic, city journeys (circuit temperature up to +125°C); - Excessive swelling of rubbers and plastic in the circuit; - Formation of deposits in the circuit also in conditions of exasperated exercise.

Specification
CUNA NC 956-16
FIAT 9.55523 CONTRACTUAL TECHNICAL REF.N°F101.M01
ASTM D 3306 Type 1
CHRYSLER MS 12106
Lotus Reference PE-00140

Facing the same type of dilemma on my Evora..... It's impossible to find the exact factory recommended coolant here. Some people have simply flushed the system and replaced with the Toyota red coolant used in the Camry (as that's the same engine as in the Evora). However, the 4c doesn't have an American equivalent that uses the same engine.

Hey, @Cpl_Punishment , I see you are online. Can you shed any light on this?
I assume the MS-12106 is the right spec for us to use here?

Thanks, but it is the highlighted part that we are unsuccessfully trying to find.

Still, the part numbers you quote do point to the MS-12106 spec cross-referenced at the link I posted above.

I think part of the confusion is that there is no Mopar coolant I/we can find that meets the material standard.

The 68163848AB does not say MS.90032 anywhere. I also can't find a photo of the 68163848GB to check whats on the bottle.

Hey guys, reviving a dead thread here as I need coolant for my Alfa as my radiator was damaged and needs replacing. The coolant that was suggested 10yr 150k miles would be the correct one. As you can see the concentrate meets that 90032 spec, and the non concentrate is the same formulation, except for it being at the proper dilution already. Hope this helps.
