It can work okay when a blender keeps everything balanced, when done in a less controlled fashion the results can be disastrous. https://bobistheoilguy.com/forums/threads/the-us-armys-search-for-a-universal-extended-life-coolant-specification.368833/

You wouldn't think chemistry works that way, and yet it can: https://www.jstor.org/stable/44581254 I'm not saying that it will, there's too many variables to say for sure, but unlike homeopathy the effect can be very real.

If that's what they used (you should call and ask like @JeffKeryk suggested), then yes, it's safe to mix with Toyota SLLC. If they did a proper flush I would probably just stick with Prestone going forward, it will provide acceptable performance. It's still annoying that they didn't use the...

Toyota coolant is Phosphated Organic Acid Technology (PHOAT), the green stuff could have been anything. You would need to send a sample of your coolant to a lab to find out. The potential problem is that the green coolant might contain silicates. Silicates and phosphates can interact with each...

We run a bathroom exhaust fan 24/7 when it's warm enough, started doing it after a member of the household caught a virus one summer. Just that small amount of air movement makes a huge difference in comfort levels.

The PDF of ISO 4925 is just a preview unfortunately, not the whole document. All the Class 7 fluids have very similar numbers, which makes other sources of information necessary. For the BASF / Bosch fluid the name and marketing copy are suspiciously similar, and BASF lists a Bosch approval /...

The "GS" mark is a German Geprüfte Sicherheit voluntary (VPA) certification, I think the actual ODM of the tool is this Taiwanese company Parget Industrial. Most of the results on Google for the YYT1 have HellermannTyton branding, and they list as being for insulated single grip terminals. If...

I found the Holts stuff on their France site, they have a whole lineup of vehicle specific coolants including one that claims to be for Ford / Opel and meet WSS-M97B44-D (should be D2 as it's pre-mix) / GMW 3240 (should be GMW 3420). The SDSs for the -30C versions of the product that have codes...

Can you post some more pictures? That doesn't look like an insulated terminal double crimp die.

The smaller area half of the nest is for the conductor barrel, the larger, typically more oval shaped half is for the insulation barrel, the wire should be sticking out of the side of the die that has the dot on it. You also need to have some bare wire (brush) sticking out of the conductor...

ELC is a hybrid OAT with nitrites (NOAT), some OEMs (Caterpillar, for one) insist on nitrites. XLC is a straight OAT, no Nitrites, some OEMs don't like Nitrites. ELC Advanced is a 'lowbrid', less nitrites, and it's safe for use in cooling systems with Controlled Atmosphere Brazing (CAB)...

Ford Super Plus Premium is Ford spec WSS-M97B44-D (or -D2 for the pre-mix), in the US the name was Motorcraft Orange before it was discontinued in favor of Motorcraft Yellow. WSS-M97B44-D is a copy of General Motors spec GMW 3420, which superseded GM 6277M, aka Dex-Cool / DEX-Cool / DEXCOOL /...

The Defense Technical Information Center (DTIC) hasn't updated Discover (the database where the research was posted) in a good while, they used to have a banner up saying they were going to update in December but now it says this quarter. A brief Google search didn't yield anything either, as...

So per Kohler's sell sheet were looking at a blue Si-OAT ELC. Turns out Kohler sources it from AMSOIL, which is interesting given that AMSOIL has a very limited lineup of coolant, with no Si-OAT or even anything blue... However the style of bottle and the phrasing of a number of lines in the...

Interesting, I wonder what's going on at HUSKEY that's holding them up from supplying 3M / Mission... Sil-Glyde is castor oil based with just a bit of silicone, AGS have a silicone dielectric product but there's no tech data for it. Synco have a straight Silicone Super-Lube but it's a thinner...

I used Isopropyl Alcohol as I recall, with good results.

The NTSB has released their preliminary report (PDF): https://www.ntsb.gov/investigations/Documents/DCA24MM031_PreliminaryReport%203.pdf

A number of these have already been touched on, but some considerations when choosing a coolant are: Pressurized / unpressurized overflow bottle - Dexcool does not like oxygen at all Elastomer compatibility - 2 EHA eats silicone Diesel engine liner type - Wet sleeve liners need anti-cavitation...

You're welcome. You have to buy a copy of ISO 4925 if you want to read it unfortunately, but it's not really worth spending the money on IMO. The table looks to be accurate, except that while DOT FMVSS 116 does not recognize "Low Viscosity (LV)", "Super", or "Plus" fluids, the ISO 4925 / SAE...

ISO 4925 Class 6 fluid effectively is all the same, there's no indication that BMW has any real specific requirements that go above and beyond DOT 4 LV (Class 6). BMW buys components and parts from ATE because ATE own the Intellectual Property rights to the designs that BMW want to use. ATE has...
