#2257918 - 05/11/11 02:15 PM Toyota Super Long Life Coolant Question

I have a 2007 Camry Hybrid that is almost 5 years old, and has 99,000 miles. I have had two coolant seal failures so far.

At 80K the water pump seal failed. At 99K the transaxle seam seal failed, leaking hybrid system coolant.

Having two leaks in under 100K miles seems unusual. Is there some problem with Toyota Super Long Life coolant attacking gaskets and seals?

I am not familiar with the hybrid Camry. I changed the pink coolant on my 2005 Camry every 30k(Drain and Refill). I did not have any problem with that vehicle.

The 2az's water pumps are about average, so that's not terribly surprising that you were getting some weeping and had the water pump replaced.

I don't know enough about the Hybrid tranny to comment.

No, I don't think either are common enough to think the coolant is a problem. They are also different seal types.

This may be a fluke or it may be a trend... But i owned an 06 Highlander Hybrid which developed an Inverter Coolant leak at about 68K. Sold it at 112k, and didn't do the 90K scheduled Timing Belt/Coolant Flush/water pump inspection due to the cost approaching $1000 and worries of the longevity of the Hybrid System and potential repair costs.

As an aside to the above. it's probably worthy to note that at the time of the Inverter coolant leak, i was denied warranty coverage for the repair even though the "Hybrid System" warranty is an 8year/80k mile warranty. Reason why i'm done with toyota as a company. In my opinion product quality of late has taken a plunge...

Interesting that you mentioned it. On the RAV4 forums there are many accounts of WP seal failures at low miles under warranty. Some members went through 3 WPs.

Mine is fine so far and will likely fail after warranty is over (in one month).

While I suspect defective WPs, the pink "super long life" coolant concern did cross my mind. I'm even considering going back to the old, red Toyota's "long life" coolant

My mom's '06 Matrix sprung a WP weep hole leak @ only 30K, replaced under warranty-but you guys are making me wonder...
Maybe I should change the wife's '05 xB coolant before it makes trouble?

I have noticed a lot of cars at work leaking with the pink stuff in it.... and its easy to see leaks because it leaves pink powder behind.....

I am a Toyota technician and I have seen an unusually high number of water pump leaks with the Super Long Life Coolant (the pink stuff). Camry 4 cylinder models seem particularly affected. I have seen leaks as low as 15,000 miles on the odometer. I have also changed water pumps on probably half a dozen 5.7 liter Tundras under 30,000 miles. Anybody else noticed this? Myself, I flushed that stuff out as soon as I got my Tundra and installed a mixture of green coolant and distilled water. From there I will change it every 2 years of 30,000 miles. Any thoughts?

Was getting ready to chime in with the same info. My '02 S-10 came with the pink stuff. It needed a new radiator last year and when I requested the pink stuff my mechanic told me that they were now off of the pink and back on the green b/c the pink was causing leaks. I've been running green for a year now and it feels great

I too have seen way too many water pump failures with these so-called 100k coolants.

I drain/refill my radiator every two years and recommend that everyone does the same. With a shortened interval, there is no need for flushes/additives, garden hose technique, or other crazy coolant shenanigans......

Toyota pink is a great antifreeze and will keep your cooling system clean. Problems are that pump lube doesn't last indefinitely, and casting sand and metal debris will constantly be washed into and through your system. The only way to get rid of the debris is to install a filter, or change the antifreeze out regularly.

Peak Global and Zerex Asian are good substitutes for Toyota Pink and about 1/3 the cost. Both are available premixed 50:50. Peak Global is also available full strength and when you mix your own, always use distilled/deionized water.

There seem to be a pattern, unless the red to pink change coincided with cheaper batch of WPs. There is a leaking WP TSB on new corollas with a revised WP part number.

My 08 xb with 2az-fe engine had the wp leak at 20k miles. Fixed under warranty and no problems with the replacement with 44k miles on the odo.

Loc: Burlington, Ontario, Canada 2006 Lexus RX400h also had an inverter leak (new inverter ($7000 roughly for the part only)covered under the hybrid warranty without any problem).

More recently, like the OP, my hybrid transmission was leaking coolant from a seam as well. This was covered under the extended warranty as the transaxle (despite containing electric motors) is NOT covered under the hybrid warranty. Again, though, no questions asked...just replaced it under the warranty ($4500 for a new tranny, part only).

I hope there's not a problem with the coolant causing these leaks...
