165 degree transmission cooler bypass valve

When the engine oil temperature exceeds 160° F. at least a portion of the oil is directed by the valve 10 to the cooler 18 by means of the line 20. Get the latest diesel news, mods & reviews straight to to your inbox! 4. 2 toward a location remote from the valve seat 44. While we expected transmission temp to rise as the truck came up to operating temp, we didn’t expect it to go 118 degrees over ambient (for those that don’t know, 100-degrees over ambient is considered the ideal operating temp for most transmissions). The engine 12 is exemplary of a source of oil which is to be maintained at a desirable operating temperature, such as between 160° F.-180° F. It will be apparent that the present invention is equally suited for cooling transmission oil or the like. Once the retainer is in place, the two legs on the air box can be forced into their respective grommets. BACKROUND OF THE INVENTION 1. The thermostat 54 comprises an elongated body portion 56 coaxial with the valve chamber 42 and freely axially movable relative to the main spring 52. While lowering the factory air box into place, be mindful of where the mass airflow connector is, make sure the coolant bleed-off hose is out of the way, and avoid damaging the charge air temperature sensor. This type of modulation makes it possible to more precisely control the degree of oil cooling. A major selling point for LinCo’s bypass valve is that you don’t have to break any transmission lines loose to install it. Unfortunately, the bimetallic valve commonly fails in the closed position, causing hot transmission fluid to constantly circulate right back into the transmission, never, or barely, passing through the cooler at all. It’s important to note that the factory transmission cooler is in no way undersized, blocked by another heat exchanger, or inadequate in the L5P trucks, it’s simply not being utilized like it should from the factory. So long as the O-rings are lubed, it reduces the chances of rolling or tearing them during installation. The present invention relates to oil cooler bypass valve actuating means, and more particularly to actuating means of the type utilizing a thermally responsive element to effect valve actuation. The LDP L5P trans cooler bypass valve! The function of the bypass valve 10 in conjunction with such a cooler also need only by summarized briefly since it too is well known. Simply put the blade between the two ears of the snap-ring and twist. Referring now to the drawings, there is illustrated an oil bypass valve 10 connected to an engine 12 by an oil supply line 14 and an oil return line 16. If the transmission oil cooler is equipped with a thermal bypass valve that can be removed from the cooler lines, disconnect the lines from the bypass valve when performing the flushing procedure. Part #: 91306ERL. Transmission Cooler Bypass Valve - Read online for free. Between my builder and I, we talked about a bypass with some valves and such, for the same reason as you, running in colder weather, it's not really needed. Engine bypass flow from port 34 to port 36 is blocked by the seated flange 50 so that all the oil goes through the cooler. This will help break both internal O-rings loose. a main spring engaged between said valve housing and said valve member and operative to urge said valve member toward said warm-up position; a thermostat having a main portion and a pin extensible from said main portion in response to an increase in the temperature of oil in said valve chamber, said pin being engaged upon said valve housing; a relief spring engaged between said valve member and said main portion for moving said valve member toward said cooling position upon extension of said pin relative to said main portion, said main spring being compressible to enable movement of said valve member in one direction under the influence of relatively high pressure acting on one side of said valve member, said relief spring being compressible to enable movement of said valve member in the opposite direction under the influence of relatively high pressures acting on the other side of said valve member. 3 is a view similar to FIG. LinCo Diesel Performance’s transmission cooler bypass valve is CAD-designed, CNC-machined, and features smooth radius’s for optimum flow. Unfortunately, the bypass valve is extremely restrictive and doesn’t allow adequate flow to the auxiliary cooler, even when the auxiliary cooler is needed most. It only kept climbing. California Proposition 65 Warning From 1999-2003 the Ford 7.3L Automatic Transmission (4R100) had an external cooler bypass tube that redirected transmission fluid from the pump output back to the return line of the transmission. 708-4739P6, UPC 621859000111 As you can see here, the factory bypass valve (top right port) hinders fluid flow tremendously, forcing ATF to flow through what is maybe a 1/8-inch gap at best. 4, but illustrating the components in a warm-up position. Thanks to its one-piece design, which is void of the factory thermostatic valve capsule and spring, the orientation of the LinCo bypass valve isn’t a concern when installing it. Product Description. Needless to say, this is where we began the second test drive—and it was the highest temperature we would see with LinCo’s bypass valve in place. HOME OF THE PATENT PENDING L5P TRANSMISSION COOLER BYPASS VALVE PLUG! With the air intake reinstalled and the clamps at both ends of the intake tube cinched down, the mass airflow sensor can be plugged back in and locked. If desired, the ports 34 and 38 could be combined into a single port )not shown) for suitable connection to the lines 14 and 20. Once in the factory block, the valve can be pressed straight down until it is fully seated. XDP Transmission Cooler Thermal Bypass Valve (TBV) Upgrade XD343 Compatible with 2013-2018 Dodge Ram 6.7 Cummins Diesel Automatic Transmission (68RFE & … It acts like a thermostat, staying closed until the temp reaches approx 190 degrees, then opening to allow fluid to flow through the cooler. However, as previously indicated, such extension is accommodated by compression of the relief spring 66. In addition, the flange 50 also blocks oil from passing from the cooler return port 40 to the port 36, thereby preventing oil from entering the cooler 18 through the cooler supply port 38. The owner runs a roofing business and hooks the truck to a trailer every day of the week. In one embodiment of the invention in which the valve member is seated against a valve seat in its cooling position, further expansion of the thermally responsive element can occur without damage to the bypass valve components since the expansion is accommodated by compression of the relief bias means. Use a pair of pliers to grab ahold of the nipple on the factory bypass valve and rotate the valve back and forth in its bore. At the end of the test loop, the Allison was running a cool 107 degrees—a 49-degree drop from where we were with the stock bypass valve in the equation. After unlocking and disconnecting the mass airflow sensor, the two Christmas tree style retaining clips that secure the air box have to be extracted (one is on the air box itself, while the second is below it on a coolant line). Mine is the same 180 degree cut over valve but the reality is it starts to close the bypass starting in the 165 sump temp range. We use cookies to optimise our website and give you the best experience on our website. Following some before and after testing, the bypass valve dropped transmission fluid temp by 49 degrees, and it did so on a 38-degree winter’s day. 4R100 Cooler Bypass Delete Kit. FIG. I've been able to monitor this effect on other cars I've had with a diagnostic interface and always had to restore the radiator cooler because the transmission temps would soar above 220 degrees with just an aux cooler alone. The present valve actuating means for operating the valve member 46 includes a main bias means or compression spring 52 which normally urges the valve member 46 away from the cooling position of FIG. Installing a transmission cooler can prevent transmission burnout. In every case this substantially reduces transmission temperatures. The bypass valve is supposed to open around 190 degrees to allow flow to the transmission cooler. The result of the bypass valve not functioning as it should is excessive heat in the transmission—and the problem only gets worse with increased line pressure in the mix, such as is often the case in built transmissions. 180 +-. Then the upper section of the bypass valve assembly can be lifted out of its bore slowly, so as to allow fluid to drain back into the bypass port while you’re removing it. Starting in 2014, GM started installing a Thermal Bypass Valve on the transmissions. Such a thermally responsive compound in a thermostat 54 of the type described is well known in the prior art. Its opposite ends engage the spring retainer 60 and the adjacent face of the valve member flange 50. This is one mod every L5P owner should be considering. UP TO 60 DEGREE TEMP DROP FOR $59.99! As previously indicated in the description of the prior art, the purpose of the bypass valve 10 is to receive engine oil from the engine 12 by means of the line 14 and return the oil through the line 16 during warm-up periods, such as when the oil is at a temperature of 160° F. or less, for example. The LDP L5P trans cooler bypass valve! & Terms of Use. Excessive pressure drops across the valve member wall 72 cannot occur because one or the other of the springs compresses to allow movement of the valve member 46a in a direction such that fluid from the high pressure zone can escape through one of the valve ports. The Next Frontier To Duramax Drivability: Duramaxtuner ECM/TCM Matched Tuning Software. Once the snap-ring is in, it’s wise to use a small flat head screw driver to ensure the snap-ring is both fully seated and spread out. A thermostat 54 is located in the valve chamber 42 and is responsive to an increase in temperature of the oil in the chamber 42 to move the valve member 46 from the warm-up position of FIG. When the truck was dropped off at LinCo Diesel Performance’s Troy, Missouri facility, he reported seeing transmission temperature climb higher than 210 degrees on a daily basis. Thus, any movement of the spring retainer 60 to the left, as viewed in FIGS. Oil Cooler Bypass Valve • For high-performance and Bowtie Big-Blocks with 4-bolt main bearing caps • Must be installed in the rear hole behind the oil filter adapter bolt to route oil through the cooler. I pulled this from an AMSoil site. I get my PML pan tomorrow so I might throw that on first. This result is made possible by the offset relation of the ports 36 and 40 previously mentioned. Once free from its mounting fasteners, the air box lifts up and rolls out of place. Use of this site constitutes acceptance of our user agreement and privacy policy.
