Where is he getting this info? He mentions the forums but I don’t remember reading anything about this.

 

Some folks in the social media groups have said that the pink fluid could be the cause of the deterioration of the valley plate sealant. Think the theory stems from the fact that Lexus switched at some point from Pink to Red..

Seems like a pretty simple/cheap thing to do just in case. I am considering making the switch myself, it cant hurt.. My 2011 does not have the valley leak (yet)..

 

I want to read up on this issue. Who discovered this? I had the leak on my 08 ISF but now I’m thinking of doing it on my RCF if this is true. Just need to research to see if this is just speculation or there is some valid reasoning to it.

 

There is a private Facebook group called "Community F" - there is a thread started by a member on October 30 about the topic.

There is some discussion about the sealant used and a few people chime in stating that the vehicle's with red coolant do not suffer from VP leaks.

There is no discovery - it is pretty much all speculation.

 

What are these claims based on? I replaced the pink coolant with Toyota red coolant on my car at 52k miles simply because i had 2 gallons (concentrate) on hand and figured it wouldn't hurt anything since I was doing a full flush anyway. I'm at 73k miles now and i don't see evidence of a valley plate leak yet but i wouldn't necessarily claim that these leaks are caused by the SLLC pink coolant either. Not sure there is any evidence to support this theory since most of the valley plate design engines came around after the change to SLLC (in the mid 2000s, if i recall correctly), and none ran the red stuff from the factory.

 

Isn't this the same guy who destroyed the side of his car because he didn't know how to properly jack up his GS-F?? I wouldn't put much faith into what he has to say.

 

Exactly. I’m curious as the reasoning to this theory.

 

must be smoking crack with this theory lolz

 

It's a cheap theory to test out and your not losing any $$ except the new "red" coolant pricing........I like his videos and he puts his content out there on YT and with that comes criticism and praise for trying something new or he's not afraid to put it out there and let his audience on his channel decide or forums decide whether or not to choose to do this

 

Waiting on Lobux’s 2 cents. He’s been neck deep in Toyota lore for years and wondering if this has been an issue with any Toyota models

 

I think the true issue with the valley plate leak has been the sealant (or lack thereof) from the factory. Everyone ive read (or talked to) that did the repair themselves said there was hardly any sealant residue when removing the heat exchanger plate from the top of the engine.

The red coolant theory I think is just another theory that people are pointing to because its an easy one to test out.

I put pink back in mine after my radiator failure a few weeks ago (right at 80k lol). Valley plate was resealed at 68k with the black FIPG sealant (that is supposedly compatible with the pink coolant).

I think coolant flushes should be done more regularly as like any automotive fluid, they break down chemically and can become hazardous to the health of the engine. Idk thats my 2 cents, im no mechanic lol.

- I did not know that Lexus/Toyota is switching back to red. When i went to get more coolant, toyota was still selling the pink stuff.

 

im considering doing the valley plate reseal (should have done it during the valve check ) and replacing the radiator at that time since im at 130k. and started reading about this red vs pink. but i need some concrete evidence that shows this to be fact, not opinion.

 

I'm one of the guys that somewhat bought into this theory and switched over to red. But I didn't just completely based my decision on what others have said. I have a 2014 ISF (recently just acquired) and a 2015 RCF. I printed out some documents through toyotatechinfo when I first got my 2015) There's a note that says the cooling system uses slllc (pink) and only use such when changing it OR equivalent non amine, non borate, non silicate, etc. coolant. Well, red is also non-all of those, except its not super long life, it's also not organic acid based? I figured that's what makes pink super long life and lasts 10 years or 100K miles. It may also what deteriorates the valley plate seal? I don't know. I switched over to red just last weekend on the ISF with just over 17K miles. I thought it wouldn't hurt to try, I'll just have to flush the system every other year. I'm hoping that I will avoid the valley plate leak and also the radiator may last longer. I just thought the pink coolant is the variable that I can easily change. Whether it is the actual cause of the leaks or not, I don't know. I also made sure that I flushed out most, if not all of the pink out, only used distilled water.

 

Does anybody know by chance what the sealant they used for the valley plate was? Like, its composition and such? I believe the red coolant is probably less corrosive because it is made to deal with copper and lead, copper of which is fairly fragile. Pink was only meant for aluminium. Pink also has Potassium Hydroxide and Sebabic acid, where as red has organic acid salt and hydrated inorganic salt. Red also has more glycol in it, pink has water as its main ingredient then its ethylene glycol, red has ethylene glycol then diethylene glycol, then water. Now, pink having sebabic acid means it is a form of corrosion inhibitor, and potassium hydroxide. All of the ingredients of both don't seem corrosive in any form. It appears they both do a good job at preventing corrosion.
