200k+ miles 4th gens have you replaced your radiator?

[94toy22re]

i currently have no issues with my cooling system but i do a lot of driving in remote areas where their is spotty cell coverage, just wondering has anyone had their radiator fail and or just replaced it as ware item. And did you buy a OEM , Mishimoto or something else?

Did a Napa lifetime on my '09 at 105k, it sprang a leak.

In the lower 48 I'd wager few do them as a maintenance item, only when they fail. Short change to do it at home in the driveway, opposed to having one flown in along with antifreeze to do the job.

edit: Remote? thought you meant Alaska, still though, if it worries you do it.

Mine failed at around 90k I think. I got a Denso from RockAuto.

Still original at 217,000.

Not quite 200K, OK only 185K on 03 V8 2WD. Recent trip to Vegas in 115+ degrees heat with AC full blast at low and flying freeway speed (uphills at times) and engine was still running cool with the original radiator. The engine temperature needle remained halfway mark, always. Love my 4Runner.

I decided to replace my radiator when I replaced my timing belt and water pump at 200k for good measure. I think it was about $350-400.

I had the radiator replaced along with the timing belt, water pump, a/c condenser, hoses, etc. I had only 144k miles but the truck is 13 years old and I'll be keeping her for a while. Btw I was told all the original parts were in decent shape when they were removed.

Mine sprung a leak just before it 100k, but the leak was minor i still drove the runner for 10k until i got around to change it

I'm at 188K miles and still on original radiator and hoses.
I drain the coolant in the rad once every 2 years and only use Toyota Red mixed 50/50 with distilled water.
I also changed the rad cap at 90K and 180K

I'm at 188k and no issues. (knock on wood)

I believe you should be using Toyota Super Long Life "Pink" not Red shouldn't you??

I think the Pink is same as RED. Pink is already pre-mixed, where as Red is concentrate that requires 50/50 dilute.

 

[lightfreak]

There's a lot of debate over Toyota Pink vs. Red.

I ditched the factory pink at around 70K and have been using red mixed with distilled water ever since. that was over 118K miles ago.

My V6 hasn't had any of the water pump leaks or head gasket problems common with this engine. Knock on wood.

My opinion is the Pink is just a diluted version of the Red, a cost cutting measure by Toyota, labeled it Super Long Life , claim it's good for 100K , so consumers think they're getting something better. That is until something goes wrong a year or 2 year after the warranty expires.

While it maybe fine to use the red in 2004 and newer T4Rs, other than the water in the pink the last 2 ingredients are different.

"Toyota Red Long Life ingredients from jug: Ethylene Glycol(107-21-1),Diethylene Glycol(111-46-6) Water(7732-18-5) Orangic Acid Salt(532-32-1) Hydrated Inorganic Salt(1310-58-3)."

"Here are the ingredients from the back of a gallon jug of the Toyota Super Long Life Antifreeze/coolant ( Pink ).
Water (7732-18-5), Ethylene Glycol (107-21-1), Diethylene Glycol (111-46-6), Sebacic Acid (111-20-6), Potassium Hydroxide (1310-58-3)."

 

[lightfreak]

I've seen that posted before. There's a TSB stating red and pink can be interchanged so they are compatible enough. I totally flushed out the pink and replaced with Red, didn't mix them.
The sebacic acid in the pink , while a great corrosion inhibitor , is a plasticizer and will soften seals and gaskets. Makes you wonder , Could this be the cause of the V6 gasket problems? Toyota redesigned the V6 head gasket with new material to withstand this ingredient? GMs Dexcool used a similar inhibitor which destroyed alot of engines and triggered a class action lawsuit.

I found my leak at 164k. I was suspicious from my overflow bottle always being low.

 

[AdmiralAugbar]

When I bought mine last August with 127k it had just had the radiator replaced (along with water pump, timing belt and transmission fluid changed). I'm at 138k right now.

 

[zonianbrat]

About to replace mine at 200K. Have a small leak.

 

[Deth527]

Just about to pass 195k. had a worry bout 6 months ago but haven't filled since. Seems that cold weather gets mine to leak. but it's very slow when it does.

 

[ecally]

2008 V6 had to replace mine at 120K
