This is why you don't use AU green coolant in your 7M

[LilMissMkIII]

The green coolant was only in my car for a few days... As soon as we realised the workshop has used it, we dumped it, however, this had already done this to a BRAND NEW water pump:

In comparison, this is the water pump (of unknown age) from another 7M we have that used Toyota Red:

Now... Which pump should I use (if either)?

 

[AndyMac]

holly shit!

is that stuff contain an acid of sorts! haha

 

[AndyMac]

does that stuff*

engrish good much morning early

 

[LilMissMkIII]

And I specifically told the guys to use Toyota Red, and even provided a brand new bottle of it.

This is just one of the reasons why I no longer have an affiliation with ESP.

 

[adampecush]

thats also an aftermarket cast impeller versus the stamped OEM toyota...

 

[jdub]

^^^ I use ONLY OEM water pumps for that exact reason

Whatever the Generic Green formulation is here it does a number on Cast Iron for sure, I had quite pronounced pitting on the deck of my 4000 Km old block using it, changed to Toyota red and it went 30,000+ Km's and looks like the day I bolted it back together.

 

[Mikael_7m]

phew....I changed my coolant a few days ago and decided to stick with the red stuff! lucky me!:aigo:

 

[LilMissMkIII]

So... Either of them suitable for use, or should I go purchase (another) new one?

 

[IJ.]

I'd use the steel one as long as the bearings are smooth.

Cast impeller = only known true waterpump failure I've seen on the forums. Never seen a stamped impeller fail.

 

[grimreaper]

All from fresh green coolant? that seems a bit excessive for a few days... if they didnt use the coolant you supplied, maybe they didnt use your pump.

I have green in the car I just got... it has been there about 5000 miles according to receipts i was provided

change ASAP?

 

[LilMissMkIII]

I ordered the pump for them and had it delivered to shop, I know 100% that the one I ordered was used, however what I didn't know was that it wasn't an OEM piece.

Not a HUGE deal, as the car hasn't been driven, thanks to all the other fuckups they made whilst they had my car, but just wanted to get peoples' thoughts on it before one of the pumps goes back in

 

[AndyMac]

that really sucks, so They totally disregarded what you asked them to do?

what work do you have them doing?

 

[LilMissMkIII]

Mate, I know you're good friends with them, so I won't be ranting about them on here.

Quite alot of people are happy with their work, however there is an equal amount who are unhappy.

Unfortunately they fucked up way too many things on my car and have lost my business for good.

 

[IwantMKIII]

will red undo some of the green's damage? ie rid of existing rust from it.

 

[AndyMac]

no no I totally understand, that really sucks!

especially when you pay a premium price for the best work, I guess its not unacceptable to expect you get what you pay for....

in your case you didnt get that!

 

[CyFi6]

I dont really see what exactly is wrong with it? Only thing i can see is a little surface rust which probably happened after it dried

Green coolant is not going to destroy your moter..Its just not as good as Toyota red. I dont think it can do that to your moter in a few days....If it did you would not have a impeller at all in a few months..And last i checked most people do not spend the time or money to go to toyota to get there coolant and its not a problem.
