New Honda antifreeze formulation?

Just changed my coolant today.

Anybody else noticed that Honda's Type 2 premix is no longer dark green,
but is now dark blue instead? I wonder what the difference is?

 

Isn't that the latest Honda coolant suppose to fit to latest model?
Can you mix Honda premix coolant with a regular brand coolant? I ask
this question
becaues I've heard that the Honda waterpump is sensitive to the
different type of coolant. Some say wrong coolant might destory the
waterpump seal.

 

here in california, it's been blue since at least 2000. expect it's
just colorant.

 

Might? No, will.

I've killed 3 of them myself. Takes 6 weeks to 6 months with silicate
fomulations before your pump seal is destroyed.

 

A friend has a 1990 with about 10o0K (miles) onit. He has used
low toxic (ethyl proponal?) antifreeze that is silicate based for
the last 70+K, over 5 years. When I read the horrow stories
I told him he needs to go back to honda AF. He is getting the T-
belt, water pump, etal changed next week. I hope to get a look
at the water pump.

Perhaps EP silicate based AF is safer the EG silicate AF.
I an't willing to test it on my Civic.

it took 3 before you finally learned?

 

ive used the orange prestone from the silver bottle for YEARS in all my
vehicles, and never had a coolant related problem.

Yup. We had two '90 Integras, one auto (ho-hum) and one manual
(vrooom!!). More pumps to kill means you kill more pumps.

Changed coolant in both, and the auto died almost immediately. Both
Acura and I thought it was a fluke. Acura put in a new pump under
warranty, and used Prestone I had supplied. Pump died again. Techline
told the Acura dealer, "don't do that." Meanwhile, the manual Integra
was still going, but did die after about 6 months. All pumps replaced
under warranty.

"Don't pick up a stranger." Yeah, right.

 

The orange is OAT based, like Dex-Cool, isn't it? So there is no
silicate.

Screw prestone.

 

Maybe they used an odd color to help keep folks from confusing it with a
"regular" formula?

 

Same here. In fact I have always used Prestone regular stuff (yellow
bottle with green colored antifreeze) but always diluted with distilled
water. Never had a problem with the stuff in any of my Civics ('83,
'91, '01). And my '91 is just over 156K miles and so far the pumps
(original pump upto 110K and the replacement one, to-date)have been
fine.
