Banks says that Turbo Cool Down is a myth!

[JRagland]

There is a lot to the story Rman says.



Most farmers in north Arkansas that drive one of these trucks swear by it. They think they are the greatest, most reliable trucks they have ever had.



My dad's 2001 gets driven hard and cold, a cattle trailer is behind it at all times, his farms are up and down 10 MPH gravel hills, he luggs the crap out of it, shuts it down to open a gate, I have to go home to change his oil (every 6-8,000 miles), air filter?, fuel filter?, anti-freeze is an immortal liquid to him. These guys all use the cheapest filters they can find and never see the dealer. In fact the nearest dealer barely carries tools for these things.



I in no way agree with this after joining this site and seeing ways to keep my CTD running longer and better, but most people can abuse these engines and never see a failure secondary to it.



Dad's engine is an experiment in longetivity for me to watch and see what happens. :-laf

I got a chuckle out of that one. :-laf :-laf

I'm with JRagland. Before I joined TDR and learned about all the tender-lovin' care these delicate trucks need :-laf , all I ever saw was hordes of farmers, ranchers, and cowboys roaring all over the highways in their CTDs in Texas summer heat hauling heavy loads - no gauges, no idling, no TLC at all. Before I bought my truck I looked at dozens and dozens of their trade-ins and never saw a single one that had any noticeable engine problems.



I am not one to abuse my truck and I do let it cool down a mite before shutdown, but if hot shutdowns were a big problem I'd think we would be seeing an epidemic of turbo replacements from the stock heavy haulers with no gauges. You wouldn't be able to buy an aftermarket turbo because the entire turbocharger mfg sector output would be devoted to filling Chrysler's replacement supply chain... !

Before my gauges (back in the Fram oil filter days ), I would let my truck "cool down". Now that I see how long it takes to cool down, I guess I had a lot of 500* shutdowns. Not saying that was good, but I would think the VAST majority of CTD owners don't cool down, don't know (or care) about TDR, etc. and their trucks are running fine. I'll cool down from here on out for peace of mind.

I Have seen 320 just pulling My Triple-axle. I always wait when pulling ,I usually see 240 empty. The other gauge is rear axle Temp 130-170 pulling,100 empty.

TWest; where did you locate your engine oil temp sensor?

Where is your probe? I have mine in the center port on the oil filter housing, I see about 200-215 empty running around town, highest I have seen is about 235-240 towing my 5th wheel on some big hills running in 3rd about 2500rpm in 90 degree weather with the AC on.

 

[TCDiesel]

I have it in the same spot, When you start to mod oil temp can be overlooked and consider not necessary, not so if you want some longevity out of it ,I tried other programmers and could hit 340 easy. The Six gun is always on level six. when set back to stock it ran about the same as you guys.

Engine Oil Cooler

So based on your experience, oil temps are running between 200 and 240 degrees. Does anyone use an auxillary engine oil cooler to keep the oil temp between 180 and 200 degrees?

 

[Hohn]

All I can say is. why is hot shut down, still in all faiure analysis cataloging from all maufacturers. I can post them if needed. They can hot shut down their trucks if they want but i will still wait until pyro temps are below 350 deg.

True, but what is the definition of "hot"? Tooling around town empty may not meet the requirement.



Putting it on a load dyno probably does.



For the most part, Banks is correct, imo. I'd let it idle for a couple seconds if I've been running it around town-- longer after hwy usage, longer still after towing.

I have very different oil temp readings than you are reporting. I have oil presure and temp in line to my turbo and have never seen more than 165. and that was with no fan shroud or fan about a month ago with incorrect timing and new injectors. I got on the back roads and idled home to make adjustments. I have not towed anything substantial in warm weather yet as I installed the guages around halloween last year. I hope my picture shows up.

Myth # 12



You can make power without decals.



There is no truth to this period! Only those who know facts believe this, avoid them at all costs.



P. S. we give decals with our products.

Hey that's neat! Why didn't you just put the probe on the other opening in on top of the oil filter housing? You may have future mods planned I guess.

I was under the impression you always wanted the oil hotter than the boiling point of water so it gets rid of any condensation that may develop in the engine.

 

[rbattelle]

(Off topic)



Heepdriver - my oil readings are very similar to yours, and I believe it's precisely because we don't have the oil temp probe sunk down into the port on the filter housing. I made up a special fitting for mine that gets it closer than yours, but still too far out of the main oil flow to measure temperature accurately. Some day I'll find a way to fix it. On the 2003-up trucks there's a coolant line that's in the way of one of the oil ports, so you can't get anything in there.

I check the temp before turbo and after 220/240 in 300/320 out, The new cooler drops it down to about 130 in 230/240 out the over all temp remains about the same 210/240. With the new cooler I have not reach 270, before I could hit 320 easy with hard long pulls. Also look at the pic with the ALT the positive cable is rubbing against it ,it wore through the loom covering .

 

[rbattelle]

Wow, nice cooler! It's a little hard to see where it's plumbed into the oil system in the pics...

It is plumbed from the feed line to turbo, I replaced the the little braid hose with the one"s you see in the picture,If you attempt this you must use a plate & fin cooler (DO NOT USE A TUBE AND FIN),About $160. 00 in materials. 1 Hr install. Stock cooler is fine until you start to increase HP/TQ and pulling or use commercially.
