How did they conclude you had Gold & Green coolants?

 

When they drained the system they had two colored liquids come out. I think the Ford Gold came out first and then the Universal Green came out. They told me the degas bottle appeared to be green before they drained the system so they initially thought the system had been flushed and refilled with the Universal Green, which they said would have been fine. They said the two coolants do not mix together and could cause blockages at turns or corners inside the cooling system flow path (term gelling was used). The original owner took great steps to document every maintenance point that was performed on the truck up to 72K miles when I bought it. I purchased the truck from a large Toyota dealer in town and we believe they topped off the degas bottle with Universal Green Coolant when they check it over/serviced it (I have spoken to the original owner). The degas bottle was completely full when I purchased the truck. It did have a very small leak on the top radiator hose (almost un-noticable), that hose was replaced when the oil cooler was replaced along with the other radiator hoses.

 

This sounds almost "scammy"

How is there no chemical to clean off some resdue? or film?

CLR flush?

Paint stripper?

ACID?

Abrasive fluid in it and run down the highway for 20 minutes then flush?

There has to be something ....

 

This is maybe all thats wrong with mine, one head is hotter than the other.

We need a real rinse chemical that will eat that crap away...

 

Problem is it is a dealer and they replace parts at any cost. Independent shop may very well have a way to clean out the system for much less money. There is no incentive for a dealer to figure out how to clean the system out.

 

How do you know you had temp problems.

 

I installed the coolant filter when my oil cooler failed at 135,000 miles ($3800.00). It was supposed to solve the problem, now I have problems again at 150,000 miles. Shop said they would warranty part, but not labor ($1500).

 

Just keeping everyOne updated... Pulled about a 6,000 lb load & a 5,000 lb load today. Spread stayed at 3-4. At 70 mph, I noticed they were dead even @ 199 degrees for a good amount of time. With 100 degree outside temp!

 

Just found out my oil cooler and t-stat needs replaced. Went camping last weekend and hammered down unloaded on a 6% grade to pass some slow pokes. Truck was a beast and passed them very quickly. About 10 min later wrench popped up on display followed by reduced engine power and went into limp mode.

Truck is an 08 Job 1 with 66,000 miles. Dealer called this am and said they needed it for 2 days. Haven't had a chance to talk to tech yet about the splits. I dont think they removed my cab. I think they loosened and tilted the cab versus totally removing the cab. I have diesel care plus and premium car warranty. Hope I don't have to come out of pocket much. Told them to upgrade hoses to double o ring, change oil again even though was just changed last week and to replace coolant.

Glad I had the 11B23 update on my truck. Without it, I would have never known there was a problem untill it was to late.

Anything we can do to prolong life of new oil cooler? I Change oil around 4000 and Will start doing coolant every 30,000. Bought truck with 50,000 and radiators were replaced 3 times. Not sure if they used new coolant or reused mine.

Ordering a filter kit tomorrow. Which kit do you guys prefer? The sinister or Dieselsite kit? One mount near bumper and other on frame?

 

I am really wondering what a waterless coolant would work like in these trucks.

It seems like cavitation issues, weird deposit issues on metal, and a handfull of other issues would be averted.

I've brought it up several times, but I can never find a real answer, just "If it worked, more people would do it".

 

I have a Dieselsite. Seems to work pretty good. I did search last year on Grainger and you can buy all the exact same parts direct from them and save about $25-30.

 

Think I am going to order a kit from them. Hope hose is long enough. Prefer black hoses over blue hoses that sinister uses.

Thanks

 

Mine wasn't...

 

Ordered mine from diesel site today. Hose length issue has been resolved thanks to customer providing feedback. Got my truck back from dealer today and installing kit as soon as it arrives. Want to protect that new oil cooler.

 

why did they removed the cab for oil cooler replacement???
