I run Zerex G05 and have had no issues. I'm sure there is some better option somewhere before the coolant police come after me
I used to be in the g05 camp but now after research i am in the G48;camp Sent from my moto g(7) using Tapatalk
Me too for the G05. However, it is not a 'true' long life (5 years) coolant so I flush mine every 3 years (I used to do it every 2 years during my first 4 years of ownership). The best one (OE recommended????) is Shell Rotella ELC or CAT ELC (not to be confused with Shell ULTRA ELC). For my last coolant change (Nov 2020) it was nowhere to be found in Canada “Shell Rotella ELC is a "fill for life" ethylene glycol-based coolant for heavy-duty diesel, gasoline and natural gas-powered engines. Shell Rotella ELC contains a unique extended life carboxylate inhibitor system and nitrite/molybdate as secondary Shell Rotella ELC meets all the requirements for CAT EC-1, TMC RP 329 and RP 338 o Improved water pump seal life due to low dissolved solid levels o Excellent heat transfer o Reduced overall coolant and cooling component maintenance”
Oem fill and recommended is g48 The shell you mentioned has been some mechanics here and now the new formula is she'll elc nf Sent from my moto g(7) using Tapatalk
This is a quote I copied from 15 years ago when I first joined FChat. Not sure who wrote it here. · What does my Ferrari require? a) Must be free of Phosphate and Silicate and must have Nitrites for the wet cylinder liners to prevent liner cavitation erosion. The BMW grey/green coolant, Shell Glycoshell and Valvoline Zerex G48 all have no phosphates. Mercedes and BMWs do not have wet liners, so G48, Glycoshell or BMW grey/green without Nitrites works well for them. However, the Ferrari 360, 430 & 550 engines also need Nitrites and those 3 do not have Nitrites. Valvoline Zerex G05 is HOAT Technology and is recommended for Ferrari but it is not a true long-life coolant. Type of coolant has always been and continues to be a contentious issue here. Hence, my belief in what was written above
Newer coolants in including the new shell include different chemicals to protect cylinder liners The G48 is called for by some diesel engines with liners Look at the approvals Things have come a long way Look at shell elc nf ..no nitrite and made for commerical trucks That all being said I don't think you can go wrong with G05 - the reason I left the G05 camp was some concerns with it attacking some heat exchangers with 360 already have had some issues Sent from my moto g(7) using Tapatalk
Some fellas in my Porsche chat group has had issues with it as well. In their case it was damage caused to the heads. https://rennlist.com/forums/928-forum/1166719-done-with-g-05-coolant-completely-forever.html
G05 was just reformulated to bring it up to date and now has hybrid organic acid technology. I have been using it for 13 years, mostly with the old formulation, and it needs to be changed every two years. The part I like is the coolant is designed to protect wet cylinder liners from corrosion. Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
Fred- G48 is readily available too, but I prefer the G05. It was not, in the past, a coolant for those who wanted it to last several years since the additives only lasted a couple of years. Since I changed it every 2 years, no problem. Now GO5 has nitrited HOATs, so not sure how long it will last. I will still change it every 2 years.
If I had a 360, I would change it annually just to make sure the heat exchanger had not taken a hike.
Actually Terry when I bought my car here was no maintenance history. So as part of the major I had the WP, Thermostat, all sensors and HX & coolant replaced. That was 2014. The next 3 years I continued flushing the system annually until a few folks here told me that was overkill. So I went to 3 years and last Nov before the big sleep I did one of those complete flushes (Black360's version) with Zerex G05
Link to Black360 flush procedure? I did a search but couldn’t find it Sent from my iPhone using FerrariChat
Mercedes Benz blue stuff. Apparently good for 5 years minimum per trusted mechanic. Used to use G05 every two years.
Well to be completely different has anyone tried Evans waterless? we are considering it ! It is in use by over 1.5 million users ! w/ No credible reported issues it is a real lifetime coolant and used by many racers Jay Leno converted over 200 of his cars i understand ! as it has NO water it will not cause erosion, corrosion , wear,it does not pressurize and as it boils at 375 Deg F it will never boil ! it would stress the cooling system much less . it is said to cool much better and cavitation is virtually impossible . Yes, it is very expensive and converting a vehicle to use it is a bit of a PIA the $ should hardly be an impediment to Ferrari owners .
I did some research a while back and here was my summary: Executive Summary: Even with the advantages I'm way too chicken to try this. Advantages: (1) One big positive is electrolytic corrosion is no longer an issue (2) Evans is unique in that it does not require pressure to raise the boiling point, that reduces the stress on older systems (3) Since it boils at 375 Deg F overheating (engine) should not be a problem (4) No more Thermostat failure as that piece of equipment gets removed (Evans recommendation) (5) Way less stress on the cooling system and so much less chance of blowing a hose, radiator etc On an episode of Wheeler Dealer (Episode with TR6) it was converted to Evans and Ed removed the rad cap on the hot engine with no ill effects Ferrari conversion to Evans: Jay Leno's recommendation: Disadvantages: (1) With Thermostat gone warmups will be longer (affects folks like me in cooler/colder regions) (2) Due to its higher density & viscosity the water pump may not develop the head or flowrate that it would normally. Problem?? (3) Its specific heat capacity is about 65% that of pure water, so it's going to be less efficient at removing heat from the engine. That's why engines with marginal (and sometimes even with upgraded systems ) cooling systems tend to run hotter with it. Damn!
Probably more because of corrosion fears than overheating fears. The big deal on Evans, as mentioned, is that it just does not have the heat capacity of a 50/50 ethylene glycol and water coolant mixture. System should really be designed to run on it from the beginning and not retrofitted.
