Cooling system overhaul part 1. 1987 Cab over Freightliner Big cam Cummins Low Flow.

[@stanleyflory6702]

Retired O/O trucker from Illinois, living in Lampang, Thailand now! That valve on the heater core line is how you regulate the temp inside the cab on the Freightliners! It hooks to your slide on the dash, and they are notorious for leaking, and only lasting a couple of years! I went thru many of them on my FLD 120! If you bypass it, regulating the heat will be near impossible, as you will have to jack the cab and close the valve a little, if too hot, etc.! They don't cost much, so i would just replace it! I was glad to see you put cardboard in front of the radiator to protect it, it only takes 1 slipped wrench, or a nick from the fan to make a bad day go really bad! I see so many guys not take the time to protect the radiator, because "they just don't have the time" Good Job!

The engine has 2 thermostats, I would replace the hoses with silicone hose and clamps the rubber grommets for the tube are available at Cummins or Kenworth dealers. The radiator hoses at the bottom does not create a hot spot, as there is a baffle in the bottom of the rad tank, water goes in, goes up to the top then over to the other side than goes down. I’ve worked on many of these engines and still have the manuals for the low flow cooling systems, there are 2 thermostats, if you don’t have any info on the thermostats and housings don’t do it unless you have some info on them there is an update to the housing that should be done. Formula is a low torque engine horsepower rating, most were 300 H P.. the after cooler is like a radiator that has water running through it. The air goes through the core and keeps the air into the engine at lower or higher temp. The coolant filters are not the same, get a filter with dca precharge, then after the next service use a dca maintenance filter. Wish I were there to help, we’d make short work of doing your engine. I’m up from northern Alberta and still work on these engines. Not many people know any thing about the old Cummins engines. I like these old engines, were easy to work on and were very reliable. Good luck my friend.

[@NOT_FOR_HIRE]

Thank you for all the info and clearing that up for me! I already ordered the thermostats and took the housing off. What is the update I'd like to do it before I put it back together?

[@gerryspang5917]

@@NOT_FOR_HIRE a book explaining the Optimized Aftercooling and low flow Radiators Bulletin Cummins 3387315 explains the whole system, I still have mine from 1985. Then their Low Restriction Thermostat housing. Cummins service and Parts Topics 87T8-8has the info you would find useful. The old style thermostat cover needed a larger hole drilled in the housing, newer thermostat cover 3042624 takes a stat with no spacer, all others use thermostat with spacer, bottom line make sure you get the same thermostats, exactly the same . The engine runs fairly hot compared to others at this time. Many of these engines and rad combinations were misdiagnosed and the rad was replaced with a normal rad and the front water rail/thermostat housing and water pumps were replaced, basically turning them back to big cam 3 technology thanks for asking, took me a while to find this stuff, at 78 years I’m still repairing the big cam engines, not many people know how to work on these engines, and there’s not much info on the manuals as they’re all electronic manual now and the old manuals were never put on network.. good luck my friend.

The Formula 290-350 Cummins came out in the mid to late '70's. It was a variation or improvement on the previous engines. I think they were High torque, low rev engines and they were marketed as fuel saving engines. Detroit were marketing the Silver 92 engines as the 'Fuel Squeezer' around the same time.

Least that screen wasn't plugged up with silicone so hopefully the radiator is still good. Couple things don't forget the DCA or the liners will pit out quick.

Wish I was there to help set the over head and roll in some bearings.

Always look forward to the next installment in this series. You're doing a great job.

[@morgansword]

I surely would open the heater box area as you will suffer some awful heat from those heater cores as they just seem to pump heat from there. I do believe it has a vent to the outside up there that will pull the heat out and keep the engine running cooler in some of the places that you travel and the heat of the day is in the nineties. The fan in the front there should come right off with the four or five bolts holding it. When you take it off, you will see that its designed to be reversed for pulling air or pushing air. I liked to push in the winter and pull in the summer and its actually easy after you do it once so those belts become a piece of cake compared to taking half the front out to get to them. I don't remember the name of the goofy pipe fitting that crossed over on top but know it keeps it from air locking itself. Very important job for it to do. I don't have any Mitchell's Manuals for Cummins but if you do find them, they are the gods of information. My memory is so feeble as I'm 73 and been a while since I raised the hood even on the family grocery getter. Best of luck from alaska... a state so big that it should be its own country!!

It was an old FedEx truck and in far better shape as far as the rust you have been running into !! Having said that I have gone through most everything like you are doing and yes it gets pricey !!! Mine was a tractor when I bought it and now it has a rugged flat bed on it and is set up with Pintle hook hitch and air for a 20 ton Interstate equipment trailer which I use for Dozer, Backhoe and paving equipment. I have used the truck daily for the last two years with very little trouble but I only use it pretty much local.

If you get a chance to- The fins of the cooling fan need cleaned and waxed, if possible. Filthy like that will barely move any air.

you have one of the first series Cummins BC IV low flow cooling. If you take the T States out look for a small hole 1/8 drilled down into the housing, the top housing should have been updated as well. Check the water filter check valves as well. Low Flow cooling was good if the system was maintained. Formula Cummins were the Fleet 1900 RPM governed engines. Kyser Cadillac built coolant systems. Your Alt pulley looks really corroded. The coolant filter number changes per the amount of DCA charge within the filter.
