Turbo 350 Transmission Cooler Lines Diagram

Turbo 350 transmission cooler lines diagrams show the flow of fluid through the transmission cooling system. The diagram will usually have a schematic that shows all of the components in the system, including the lines going to and from each component. There are two types of coolers: external and internal.

External coolers use air to remove heat from engine oil before it enters the transmission while internal coolers utilize a radiator or other type of heat exchanger to reduce temperatures inside the assembly itself The Turbo 350 uses both an external cooler line routed from a thermostat on top of the radiator, as well as an internal cooler within its own housing. The diagram should also include any additional hoses that connect directly to either side of these two main components for added protection against overheating and wear caused by extreme conditions.

If you’re looking for a Turbo 350 transmission cooler lines diagram, then you’ve come to the right place. Here we will provide an overview of how these lines are installed and connected, as well as tips on how best to maintain them. We’ll also discuss why it’s important to have them in your vehicle in the first place.

With this information, you should be able to confidently install and maintain your own turbo 350 transmission cooler lines with ease!

Th350 Cooler Line Pressure

The cooler line pressure on a TH350 transmission is typically set between 40 and 50 PSI. This pressure helps to keep the fluid temperature steady and also prevents damage to the internal components of the transmission due to extreme wear or heat. It is important to properly diagnose any issues with your transmission before attempting to adjust the cooler line pressure as incorrect settings can lead to further problems down the road.

Which Line is the Return Line on the Th350?

The return line on the TH350 transmission is typically located at the rear of the transmission, but may be located elsewhere in some vehicles. It’s usually a rubber hose that runs from the bottom of the transmission to either an external cooler or directly into your vehicle’s radiator. The return line carries hot fluid from the transmission back to where it can be cooled and reused.

To avoid any confusion, it helps to check your vehicle manual for specific instructions regarding where this line should run in order for it to function properly. Generally speaking, however, you’ll want to ensure that this line is running away from any heat sources such as exhaust pipes or manifolds; otherwise you risk burning out your system due to excessive heat exposure. As with most automotive components, proper maintenance and repair will go a long way towards keeping your TH350 functioning optimally – so make sure you take time periodically inspect all lines connected to this important piece of equipment!

How Do You Know Which Transmission Line Goes Where?

When it comes to transmission lines, it is important to know which line goes where so that the system works properly and efficiently. To ensure this, there are several methods you can use to determine the correct placement of the transmission line. Firstly, when laying out the lines make sure that they are in line with any existing infrastructure such as poles or towers.

Secondly, locate where each end of the line will be connected by mapping out all possible paths and then laying down markers along these points. Thirdly, check for obstructions along your route and take into account any local regulations regarding power lines. Finally, use a multimeter or other device to measure continuity between different points on the transmission line and confirm its connection before finally installing it in its final position.

By using these methods you can make sure that your transmission lines go exactly where they should be and avoid costly errors which could disrupt your system’s performance.

What Size are the Transmission Cooler Lines on a Th350?

The transmission cooler lines on a TH350 are typically five to six inches in length. The larger of the two lines is usually three-eighths inch in diameter, and the smaller line has an outer diameter of five-sixteenths inch. When purchasing replacement lines for this particular transmission, it’s important to make sure they conform to these dimensions so that they fit correctly and allow for efficient cooling.

Additionally, when working with any type of automotive fluid or component always remember to take proper safety precautions such as wearing gloves and eye protection while handling them.

Which Transmission Line Goes to the Cooler?

When it comes to transmission lines, the line that goes to the cooler is typically referred to as a “coolant return line”. This line serves as an important part of any vehicle’s cooling system. It carries hot coolant from the engine back to the radiator where it can be cooled off and circulated again.

Generally speaking, this particular line runs from near the rear of your engine all the way up front around your grille area, then down into the radiator itself. If you look closely at your vehicle’s engine bay, you should be able to spot it easily enough – just follow its route! As with any automotive maintenance task, though, we always recommend consulting a professional before attempting anything yourself – so if you have any doubts or questions about which transmission line goes to the cooler on your car or truck, seek out expert advice first!


This blog post has provided a detailed explanation of the Turbo 350 transmission cooler lines diagram and how it works. It is an important part of any car’s cooling system, as it helps to keep the fluid temperature under control and prevents overheating. Knowing this information can help you diagnose problems with your vehicle more quickly and accurately.

With the right understanding of these diagrams, you can ensure that your car stays running smoothly for years to come.
