This cooler is the factory cooler found in the Ford Superduty V-10 models, but it is a great upgrade for the 1999-2003 7.3L powerstroke trucks. This is a Tru-Cool brand cooler. Tru-Cool makes the OEM coolers.
- The stock 7.3L cooler is a 28k GVW model. This V-10 (Tru-Cool Max 4739) unit is a 40K model.
- This V-10 unit IS THE SAME cooler as the Tru-Cool Max 4739 - with different hardware. Please choose the correct cooler for your needs.
- The brackets on the V-10 cooler shown here make it easy to bolt this unit in place of your OEM cooler. (You may have to splice your own lines in some models- the brackets are an exact match)
- The V-10 model of the Tru-Cool shown here is NOT an add-on cooler to your OEM unit. It replaces it.
- There is no hardware, lines or fittings included in the V-10 model.
- If you wish to add another cooler to your existing one (recommended), then the unit you are looking for is the Tru-Cool Max 4739 shown below in related products. The Tru-Cool max is an add-on cooler with all lines, fittings, and instructions to install it inline with the OEM cooler (with optional install kit).
- You CAN run the V-10 upgrade in place of your OEM and then add the Tru-Cool 4739 for even lower temps. We double up in our company truck. These two coolers in sequence can still pass the OEM flow rate test with flying colors.
FAQ
Q: I have added an additional cooler to my Powerstroke truck and I still see higher than expected temps. How do I check to see what is wrong?
A: IMPORTANT! The temps should be measured in the pressure port in the driver side of the transmission body. If you are measuring temps from a tee in the output line, temps will read about 30 degrees hotter than temps read from the pressure port.
TESTING:
- Bring the transmission up to temperature. It needs to be at least 100 degrees for this test.
- Turn the truck off.
- Remove the rear line from the transmission and place it into a bucket or similar container so that you can measure volume of your flow.
- Have someone turn the truck on.
- At idle (in park), you should measure 32 ounces of fluid in your bucket - in 15 seconds or less. This is an absolute minimum number. A properly working transmission will flow that amount in about 10 seconds or less. You should not see ANY fluid pumping out of the rear transmission port.
TEST RESULTS:
- If you have the proper amount of flow, your transmission pump and coolers are working fine. SO, if you are running hot and have the proper flow (with no fluid coming out of the rear transmission port), you most likely have a mechanical problem causing high heat. This could be torque converter slippage or one of many other internal problems. You may have to see a professional at this point to help diagnose the problem.
- If you do not have proper flow, OR you have fluid coming out of the transmission rear port, you either have a cooler blockage, OR a faulty cooler bypass valve. Here's how to tell.
- Trace the forward transmission line to the front of the truck.
- Remove the line from the 1st place it enters a cooler or the radiator (if so equipped).
- Now, do the same flow test checking flow at this point.
- There are two outcomes.
- The first is that you now have enough fluid flow- this means your cooler /coolers are partially blocked. To determine which cooler is plugged you would perform the same flow test through one cooler at a time.
- The second outcome will be that you don't have enough flow even with all coolers disconnected. This means you have an internal pump problem.
IMPORTANT! The outcome of this test assumes that you have NO fluid exiting the rear port of the transmission. If you perform a flow test with the coolers disconnected and you get fluid from the rear port on the transmission, your cooler bypass valve is bad.
