There's not much information on the FVP AF, but if I had to speculate, a universal Dexclone. I wouldn't add it. Before I'd do that, for a cup or two, I'd top up with some distilled water.

Buy a jug of Purple premix at the dealer. Failure to adhere to this may well turn your coolant into jello. Tap water is fine in small doses.

If it is indeed OAT, I'd use the new Peak 10X. I'm replacing my Honda and Toyota fluids with it. Discussions of it here: https://www.bobistheoilguy.com/forums/ubbthreads.php/topics/5230145/peak-has-a-new-antifreeze and here: https://www.bobistheoilguy.com/foru...e-this-peak-in-uh-everything#Post5305645

Agree completely.

You'll be perfectly fine adding that FVP Multi-Vehicle coolant into your Fiat 500E. The FIAT came with the purple Chrysler OAT coolant which is essentially Dexcool with a different dye, the FVP Multi-Vehicle is just another OAT dexclone dyed yellow. If you add it to the Chrysler OAT nothing will happen, your coolant will stay purple because the universal coolants are dyed yellow to not change the factory coolant colour even if it is different. And before somebody barges in and says the Chrysler OAT has no evil 2eha, to that I say the FIAT was designed in Italy to run on a G30 type coolant (Paraflu UP) which is also known as Dexcool with 2eha included.

Pretty sure that's not correct. My Alfa came with Paraflu UP from the factory and the SDS makes no mention of 2EHA.

Stick with OE coolant as there isn't an exact aftermarket match. Many many close formulations, but not exact. If you need to make a quick top off, add some distilled. Maybe 1-2" above the add marks.

Preface by saying, I don't own an FCA vehicle but my advice as above be the same either way. I would not run DexCool or a universal Dexclone using 2eha as inhibitor in it's formula. That would include FVP if it is a Dexclone using 2eha. When FCA switched to the OAT AF in 2013, an SAE paper on the then new Mopar AF OAT was published and has been oft posted this subforum. Unfortunately now to read it all, one must subscribe. However a preview of article still available linked*, and if interested subscription free for 30 days. A relevant except from the paper has been saved on this subforum; "Neither Chrysler nor Fiat has released the complete composition formula for their antifreezes. They reportedly are cocktails of three organic acids, featuring sebacate, but no 2-ethylhexanoate (2-EHA). The latter is a cost-effective but controversial additive that softens plastics, particularly silicone, leading to leaks from affected sealing materials, which means that silicone cannot be used in gaskets, O-rings, and hoses if the antifreeze contains 2-EHA." Two different Motor Mag articles over the years on 2eha in AF basically said similar. Of course what others choose to do with their vehicle, their call. https://www.scribd.com/document/375...T-Antifreeze-for-Longer-Service-Interval

Thanks folks! I am in Chandler AZ, where it rarely hits freezing. I'm thinking I should fill to the max line with distilled water and call it good. If it gets below that again, maybe I need to head over to a Chrysler or Fiat dealer and get a jug of the purple 50/50… Doig

Well the FVP has 2-EHA in it (https://www.fvpparts.com/application/files/7915/4457/5504/FVPMV50-50-GAL.pdf) so the conservative choice is not to use it, yes? Does mean it shouldn't be used in anything? I already topped off an ‘07 Subaru and ‘13 VW with it eek Thanks again, Doug

Well, as far as i know, neither Subaru's or VW's OEM coolants use 2-Eha so if you only topped off a small amount it's probably ok but i wouldn't do the same again if necessary.

VW has been using coolants with 2-eha since 1996, when G12 coolant was introduced on the MY 97 vehicles. A '13 VW would come with G13 coolant which has 2-eha, so your gaskets are safe. http://www.worldpac.com/tagged/ANTIFREEZE_G013_A8JM1.pdf Subaru doesn't discloses if they use 2-eha, but it is assumed that being a typical Japanese P-OAT they use sebacate instead of 2-eha. Sebacate just like 2-eha is also a plasticizer, so again ypur gaskets are safe unless you think the factory coolant is eating they away right now.

Sebacic acid and its derivatives such as azelaic acid have a variety of industrial uses as plasticizers, lubricants, hydraulic fluids, cosmetics, candles, etc. It is used in the synthesis of polyamide and alkyd resins

https://pubchem.ncbi.nlm.nih.gov/compound/sebacate The irrational fear of 2-eha is linked to the introduction of Dexcool in MY '96 GM vehicles, and the problems they where having around the time with failing intake manifold gaskets on the revised Buick 3800 V6 engines. GM had started using revised plastic intake manifold gaskets on the 3800 that failed at a high rate right around the time they switched to Dexcool, and everybody attributed these problems to the new coolant and it's new organic acid corrosion inhibitor 2-eha. In fact the new plastic gaskets failed regardless of what coolant was used, as some of the new 3800 engines left the factory with the old green IAT (2-eha free) coolant and suffered the same problems. GM revised the gaskets, and the problems largely went away, however for many people Dexcool and 2-eha are still linked the 3800 leaking gaskets. GM's then heavy use of the now largely obsolete iron engine blocks (which rust when run low on coolant) and wet type intake manifold gaskets (which can leak coolant), as well as quality control issues with radiator/coolant reservoir caps also unfairly tarnished the reputation of Dexcool and 2-eha.

How can you ascertain or quantify the aggressiveness of 2-eha or sebecate to plastics? And where did this 2-eha or dexcool destroys solder myth start, and why do people keep perpetuating it? If you look at the PDS of various OAT dexcool/dexclone coolants that use 2-eha you'll see in the industry standard ASTM corrosion tests they have no issues with eating away solder. For instance Zerex Dexcool corrosion results for solder are 6 mg/specimen using ASTM D1384 (spec min value is 30 mg) and 5 mg/specimen using ASTM D2570 (spec min value is 60 mg). It's a similar story for Havoline Xtended Life (a typical generic dexclone) that has a solder corrosion value of -2 mg under ASTM D1384. https://sharena21.springcm.com/Publ...bd3/5a76d5fc-0cbd-e711-9c12-ac162d889bd1 https://cglapps.chevron.com/sdspds/PDSDetailPage.aspx?docDataId=428420&docFormat=PDF The only coolant I could find that has a increased amount of solder corrosion under the ASTM tests (but still passes them easily) is Zerex G40 which scores 24 mg of solder corrosion under ASTM D2570. Zerex G40 which is the newest Mercedes coolant contains no 2-eha. I would of liked to compare the ASTM test result values of other manufactures like Peak, Prestone, Comma, etc but only Valvoline/Zerex and Havoline publish their test ASTM test results in their PDS or PI sheet. https://sharena21.springcm.com/Publ...bd3/68cbf343-0dbd-e711-9c12-ac162d889bd1
