Expert Answers about Engine Oil Coolers


  • How to Figure Out Which Transmission Line is Return Line 1997 Chevy S-10 for Transmission Cooler
  • The best way to determine which line on a transmission cooler is the return line from the radiator is to use the following procedure: 1. Start engine while engine is cold 2. Place transmission shift lever in drive for no more than 10 seconds 3. Place in Park, stop engine, and remove keys 4. Identify the oil return line by feeling both oil lines. The coolest line is the oil return line. On the aftermarket transmission cooler the ports are not input specific or output specific. It is not...

  • Can I Reuse Temperature Gauge with Derale Transmission Pan Cooler
  • I spoke with contact at Derale and he said if your existing temperature gauge is the Derale Temperature Gauge Kit for Transmission or Engine Oil # D13009, or another model that fits into the drain plug hole (1/8" NPT thread size) on the transmission pan then you can reuse it with the Derale Transmission Pan Cooler # D14207. The replacement oil filter is # D13092

  • Oil Filter Relocation Kit for a Perkins 4.236 Diesel Engine
  • From what I could find on your Perkins 4.236 Diesel Engine, it has threads that are 3/4"-16 for the oil filter. As long as that is correct the Derale Oil Filter Relocation Kit for Multiple Engine Thread Sizes # D15748 will work with your engine. The Derale Oil Filter Relocation Kit for Multiple Engine Thread Sizes # D15748 does not include a filter. The new filter that you install on the filter mount that comes with this kit must have 3/4"-16 filter threads.

  • Options For Replacing A Tie Down Turbo Lube 48394 Clear Oil Bath Cap
  • Though we do have the Bearing Buddy # BB2441T-SS that is a direct replacement for Tie Down's Turbo Lube oil baths, this will require you changing over to grease instead of oil. With that said, we do also have the Kodiak XL ProLube Kit # XLPROLUBE2440KIT (or # XLPROLUBE2440 as a single cap) that will measure the same, but the end that sits in the hub is not threaded. To get this to fit, you would either need to have the ends of the caps threaded, or have the threads turned down on your...

  • Can Factory Trans Cooler in 2005 Jeep Grand Cherokee V6 Be Bypassed with Aftermarket Derale Cooler
  • Usually an OEM transmission cooler will be located inside the radiator where engine coolant will work to lower it's temperature before routing it back through the transmission return line. In such a situation a failed radiator can cause leakage of coolant into the transmission, a fairly common problem on some Nissan vehicles. Some do use two separate cooling assemblies that can be stacked together or that are made as one unit but I am not aware of auto makers actually routing the trans...

  • Can a Factory Transmission Cooler be Bypassed by an Aftermarket Cooler
  • You can bypass your factory cooler if you wanted to, but typically people use our coolers like the popular # D13503 as a supplemental cooler installed downstream of the factory cooler. To bypass yours though would only require you to run the lines of your factory cooler to the # D13503 instead.

  • Replacement for OEM Transmission Cooler in 2006 Ford Crown Victoria Police Cruiser
  • The aftermarket oil and transmission coolers we offer are intended to supplement OEM coolers that are built into vehicle radiators. These supplementary coolers are typically employed for towing applications. Products like the Derale Series 8000 Plate-Fin Cooler that you referenced, part # D13503, and others that we offer are not intended as replacements for original equipment components. A police-spec vehicle usually has heavy-duty components in the braking, transmission, electrical and...

  • Correct Replacement Thermostat for Derale Hyper-Cool Remote Transmission Cooler Kits
  • The correct replacement thermostat for the Derale Hyper-Cool Remote Transmission Cooler Kits like part # D13960 or part # D15660 is the Replacement Thermostat for Derale Fan Controls part # D16728. The thermostat has spade connections on one end where the wires go so carefully pull the wires off this end by the connector and then thread the old thermostat out.

  • Parts Needed to Upgrade to Disc Brakes for 7,000 lb Trailer Axles
  • Yes, you can definitely upgrade to disc brakes and an oil bath setup like what we find with the Kodiak Disc Brake Kit # K2HRCM1337-9DAC, which is rated for a 7,000 lb axle. You will need the Bearing Kit # DBRKHW890 for each rotor. This comes with the inner bearing # 25580, outer bearing # 02475, and an oil seal that has a 2.250" inner diameter. You also need some bearing oil which you can find on our site as part # XLPROLUBE. Then for a brake line kit we have a few different options. I...

  • Recommended Replacement For A Tie-Down Engineering Disc Brake Hub
  • I will start by saying that your TDE 11033L hub uses the # L68149 inner bearing and # L44649 outer bearing, which means you have a pretty standard #84 spindle on a 3,500 pound axle. With that said, we do not carry Tie Down Engendering products, so the actual hub will cause some difficulties. Especially being oil bath as hubs for this size axle were only ever really done by TDE. Just as an example, if you look at the Kodiak Trailer Hub # Q-HUB84545 that will fit the Kodiak 10" Rotor # KR10D,...

  • Replacement Hub For Obsolete Tie Down Engineering 3,500lb Hub 11033L
  • I may have a grease hub option for you, but as Tie Down Engineering doesn't make parts anymore and hasn't for a while, there just isn't a replacement 11033L hub for your trailer. Verify that your hub uses the standard 3,500lb bearing combination of # L68149 inner bearing (1.378" spindle diameter where bearing rides), and outer bearing # L44649 (1.063" spindle diameter where bearing rides), you can check for the bearing numbers stamped on the bearings or the use digital calipers # PTW80157...
