99 tacoma v6 overheating

lol

 

Sorry you can’t read.
Your anecdote bad, mine good? Really? That’s how you read that?

how about one anecdote says one thing, the other one, says a different thing.

the manufacturer recommends one thing, so I use that one thing.

not that difficult man.

 

Good question, I bet Toyota chemical engineers have the answer for you.
All I know is I use what they recommend and don’t seem to have issues. By all means, put water in you truck for all I care. That will “work” for a period too.

oh I’m sorry I didn’t know I had to spell it out for you.

 

I prefer yellow!

But VW has this dope Purple one now. BMW uses blue raspberry, doesn't taste as good as it looks.

Bottom line, as long as you don't mix em, green, yellow, red, pink.... they all work fine, the only difference is the interval at which you change them out

 

The answer is Toyota had to go a certain route and went with it - the very same way Detroit engineers chose another route and went with it. There's no magical effect a coolant has on materials which are used for engines spec'd for both.

The use of the 22re anecdote didn't indicate it was shedding light to how anecdotes may serve both arguments - the tone of the phrasing much more clearly gave the impression you thought you were right.

 

Ya. Hence the immediate post I made after. Talking about each being an anecdote.

However, with that being said, one anecdote complies with Toyota manufacturer recommendations. The other does not.

 

You're entitled to your opinion, you're not really making a convincing argument with people having personal experience and reputable sources not agreeing with you.

 

And absolutely none of this talk of coolant types has anything to do with this man's truck getting slightly warm (a complete non issue).

 

I have to agree. I would suspect head gasket leaking. I had a car that was overheating and that was the cause. It was leaking slightly enough into the cylinder, and not mixing oil and coolant, which is a tell tale sign. Get an oil analysis done. That will tell for sure.

 

My 4 banger did that actually, but it would get pretty hot climbing a grade, about 225 or more without even being in the gas much. Ended up having a cracked head. The 4 banger is known to run cooler though so it was more of a tip off. I've seen the 5VZ run at 210 when in perfect condition. Part of the reason the factory temp gauge is deadened in the center. 160-220 approx.

 

It's as if the Toyota engineers are being put on a fairly high pedestal here - almost god-like.

Yes, Toyota engineers are smart, and know what they are doing (if we ignore their lower balljoint design). It's why we all drive them and are passionate about them.

That said, certain things, like the exact brand and type of coolant they recommend in all likelihood are NOT engineering decisions, but management/marketing ones. Everyone likes to play off whatever coolant as being "special" so that people will come back to the dealer and buy it.

But back to the OP's original question. As I said before, 210 doesn't seem all that hot. especially if you're not getting warning lights.

 

Damn, the irony though...

 

I notice you have a non OEM drive shaft\upper control arms.

I thought the Toyota engineers knew best

irony squared

 

You're kind of digging yourself into a hole here.


Anyway OP, 210 is at the upper end of the spectrum of normal operating temp and moving the jiggle valve to the 6 o'clock position would most likely help if it's not already there - I've had temps in that area at idle with mine prior to replacing everything in my engine bay including the radiator and now get 184 at idle but with an all aluminum (not OEM) radiator. Let us know if that helps or if your jiggle valve is at 6 o'clock already.

 

So I guess your argument from personal experience is a valid one

 

Oh you sure got me there!!

So why does prestone make this proper coolant that they recommend for Toyota

Edit: as opposed to their green stuff for other vehicles?

 

You need to let go, it's okay.

They make one that safely mixes with Toyota Red and another that mixes with Toyota Pink because they're (say it with me) SAFE TO MIX. If you've already gone to the effort of flushing the original red or pink out theres no reason to continue with them, they make other coolants that are not SAFE TO MIX (you getting that part ?) that work absolutely fine in our vehicles and have all of the same anti corrosion properties. If I was prestone I'd make the safe to mix ones too cause I can charge more for them on the basis of propriety and then I have something that can be used for people just topping off or changing one component or whatever, Zerex does it too. There's only one major coolant that shouldn't be put in anything that doesn't specifically call for it and that's Dexcool.

 

Okay
Okay, I’ll concede you can do it right with mixing and all that with the proper coolants.. I just assume use the factory coolant and all is good.
But I digress


Aside from all that thermostat stat should open between 178 and 183. And it shouldn’t really go more than 10 degrees above if the coolant system is working properly, from what I understand. So 193-195 I would call okay. But 210 still seems high to me. But what do I know, I use Toyota red
