Hello All:
I have a 2016 F350 6.7
Installed the SPE intercooler along with their higher flow lower temp coolant thermostat. they also recommended removing the thermostats from the secondary radiator so I did.
Truck runs great and with outside air temp of 55 to 60 degrees and pretty flat terrain the truck runs consistently close to 185. with rain it has dipped to 175 slight grades up to 190. I recently received the limp mode warning (exhaust) and had the shop look at it. they performed a static region. its been operating ok, about 500 miles put on it and it has performed an exhaust filter cleaning in that time
My question, will running the truck at these temps effect the exhaust temps and prevent regenerations and cause problems with the exhaust system

It shouldn't prevent regens as they should be mileage based IIRC, BUT they likely won't be as effective or will take longer since I believe your truck uses the injectors in the engine to bring exhaust temp up (I don't think you have the 9th injector like newer trucks do). I would suggest, as I do to many others, to get out on the expressway once every couple weeks and take it for a nice long drive, get everything heated up good, maybe pull a trailer with a load on it while you're at it.

thank you for the input. The truck is not a daily driver and is for the most part all highway miles. the shortest trip we make is from LA to San Diego, about a 2 hour hop. rarely in traffic as we arrange travel times to miss it.
Is it feasible to put in the later generation injectors if the 2016 does not have them and is a periodic static regen worth doing. If so how often?

Can't tell you if the later gen's 9th injector can be retrofit into a 2016, but there would be programming required to activate it.

For peace of mind, I would say a static regen might be worth doing. Can't tell you how often though.

 

RGR
thank you so much

 

You do not have the 9th injector on that truck. The after treatment system likes HEAT to work properly. I would have waited to make your mods until the truck was deleted if that is your goal. Easy to activate static regen capability with FORscan depending on your trim level.

 

THX Boaterguy, I live in California and always wanted a diesel however the wife hates the smell, so the new systems allowed me to finally get a diesel truck. the two factors of living in a communist state and keeping the wife happy I intend to keep the truck as stock as possible. As it is turning out it seems there is going to be a trade off between running hot to appease the emissions issue or maybe more frequent static regeneration episodes. This crusade started when my engine temps hit 245 coming down the 95 out of boise Idaho. Hot day long grade and towing our Bronco. So just trying to get handle on what will work best.

 

Oil temp in the 240s is normal when towing heavy up a long grade. The fan will kick on when it hits that level, and the temp will stop climbing. It will drop fairly quickly when you start going down the other side. Absent emissions systems, would cooler temps be better for the engine internals? Probably, but the truck was designed to run on the hot side to keep the emissions happy. You don't hear a lot of stories of these engines failing internally, so they seem to be able to take it.

 

Went to Ford today. bought the OEM thermostat, I think I will go back to the original operating temps. I think the lower temp higher flow stats are for the guys that run deleted trucks. I believe my emissions will give me bigger problems if I don't and I definitely don't want the limp mode crap to pull up on my dash while in the middle of a cross country trip.
Thank You all for your input, you have helped me big time to make an educated decision.
And of course the people selling the lower temp thermostats tell you it's fine no problem. So there you have it

 

Yeah when it comes to aftermarket (or any market, really) it's buyer beware. It's always better to do some research on if an idea is worthwhile or not. At one time, lower-temp thermostats were a great idea, especially when chasing performance. Today, with higher levels of emissions systems, you can't just slap one in and not expect problems if you haven't done other supporting mods (such as a delete).

 

I have a 16 as well. I wanted to buy PPE's CAC (intercooler), but the more I think about it, the SPE looks overbuilt, not cheap but pay once, cry once... I obviously see higher temps in the late spring/summertime here in WNY but nothing crazy... UNLESS I have my 8' Meyer commercial sized plow on, then she runs a little hotter as it's hard to find the right height to carry the plow in as having a big curved piece of steel hanging off the front of the truck will affect air flow into the front... anyways, it's already 51 degrees today and supposed to get a little warmer. I'll keep track of the oil temps and the trans temps for comparison for you.

My truck is a daily driver and do no hauling at all. I have the terrain help me keep my emissions happy. The altitude climbs (on the way home) as I head south on the expressway I take to work everyday... it gets the EGTs up some to keep the regens out to at least 400 miles. The last regen I did was triggered mileage as the dash said 90% (and not FULL). The regen went live at 518 miles (IIRC) since last one... but sometimes with more stop and go driving and lower speeds, the truck will go under 400 miles. The hotter you get EGT14, that's Bank1 sensor #4 that I just call EGT4 which is the temp of the exhaust gases coming out of the DPF, the further out your regens will go because the particulate filter will passively burn off soot in the filter at 572 degrees. So, either pulling a load or driving uphill, or a combo of both, will allow the truck to passively regen soot which will allow the active regen cycles go out further than just a stop and go local driver.

I also use additives which help to rise the cetane level in the fuel I buy, so more cetane, better burn.

What would help you would be a digital monitor to monitor when your truck goes into regen and to monitor other things. Our gen trucks do briefly display the "CLEANING EXHAUST FILTER" but it is easy to miss because it briefly displays for a few seconds and that's why I run two iDash units.

Going back to the original thermostat will probably help your regen cycles... unless you were loading your truck to the max and working the heck out of it, I don't think you need that low temp thermostat, but the high flow capability is nice though.

What are your trans temps with the thermostats removed in the secondary system?

 

I have a think car 689 scanner that will monitor all that and do regens I believe but I have to learn how to use it. Having the info on the dash sounds super appealing because your right about the regen notification, its there then its gone and you never know if it stays in regen or when its done. As for the Trans temp, it came way down as well. I did install the mishimoto trans cooler that helped a lot, (like I said I already bought all their crap). The trans has been running 10 to 15 degrees over the engine temp at about 195 to 200. Although all that will change when the original thermostats go back in the truck I'm sure. so to do work with the trans temp alone I am thinking of the SPE trans cooler to help the Mishimoto air trans cooler. I is a bit larger than stock and supposed to provide more cooling. I think that is about all I can do to help the transmission temps. I will give you more accurate numbers once all the stats are back in the machine. And thanks for the I Dash tip. I am going to look into that.

 

FWIW, mine is completely stock, and I've never seen the transmission temp go over 205, even when towing a 13k lb 5th wheel up long mountain grades in hot weather. When driving long distances on the highway, the trans temp stays remarkably steady within a few degrees either side of 200, whether I'm towing or unloaded, and pretty much regardless of outside temps. Perhaps individual trucks are different, but for my truck, I don't see a need to spend money on aftermarket transmission cooling.

 

Yesterday on the way home from work, ambient temp at low 40s, altitude climbs on expressway and hills to climb when off expressway going home... ECT was 187 to about 192 degrees, EOT (185 to 187) averages about 2 or 3 degrees below the coolant temps. Stock thermostat and stock CAC. And my trans temps are usually hotter than my oil temps, not much, but I do maintenance on my 6R140 by dropping the fluid and filling up new Mercon LV, changing filters and I use Lube Gard additives. I have done 4 fluid changes now, 3 filter changes and the truck has 148.4k miles.

Personally, don't think it's your engine temps as it is your flat terrain you drive on that affect regens when it comes to how far out there are... for me, driving on a 65 mph expressway while climbing hills gets mine fairly hot because the engine is working harder than just stop and go traffic.

I think because you have not been monitoring the regens, your truck was not completing regens and the DPF filled up past the safe limit, so the PCM put it in derate mode to protect the filter was filling up more. And to note, the nice thing IMO about the Banks iDash is that I can command a static regen from the iDash as long as the parameters are met. With a digital monitor, you monitor the active regen so the truck completes them and the DPF will not overfill.

 

What is the model # of the Banks Dash ? So you can throw it in the regen mode while you are driving or do you need to connect it to the truck when turned off ?
My drives between LA and San Diego are pretty flat however our deserts have some long grades. Willibe has numbers that are crazy good, don't know what to say about that. before removing the secondary thermostats and installing the cooler on. my truck ran right around 210 consistently with the trans temps about 10 degrees over unless on long grades then everything climbed from there. I picked up the new stock thermostats yesterday and have the SPR oil cooler on the way. I will do an oil flush when and change when it arrives and reinstall all the proper thermostats. Will check into the Banks Dash system, sounds like it really keeps you informed as to the engine operation. Can you get oil pressure out of the Dash ?
