LML EGR delete coolant hose routing

If you are looking to do an LML EGR delete, one of the first steps is to determine the correct routing for your coolant hoses. There are a few different ways that you can route your hoses, but the most important thing is to make sure that they are not going to come into contact with any hot surfaces.

One popular way to route the hoses is through the radiator fins. This keeps the hoses away from the hot engine and exhaust components, and also helps to keep them cooler.

Another option is to run the hoses along the outside of the engine, but this can be more difficult to do and may require some modification to your engine bay.

Once you have determined the best route for your hoses, the next step is to install the EGR delete kit. This will usually involve replacing the EGR cooler with a block-off plate, and also removing the EGR valve itself.

After the EGR delete kit is installed, you will need to re-route your coolant hoses to their new location. Make sure that they are not going to come into contact with any hot surfaces, and check for any leaks before starting your engine.

With the LML EGR delete completed, you will notice an increase in engine performance and efficiency. Your truck will run cooler and produce fewer emissions, all while saving you money on fuel costs.

What is an LML EGR delete and why would you want one?

An LML EGR delete is a device that helps remove the excess emissions from your engine, thus improving its overall performance. Many people choose to use an LML EGR delete because it can increase fuel economy by up to 5%, and it also extends the life of your engine by preventing the build-up of harmful deposits. In addition, it can also help your engine run cooler, which is especially beneficial in hot weather conditions.

How to install an LML EGR delete?

Installing an LML EGR delete is a relatively simple process, and can be done in about an hour with basic hand tools. The first thing you’ll need to do is remove the old emissions system from your engine. This includes the EGR valve, as well as the associated hoses and tubing. Once this is done, you’ll need to install the new EGR delete kit in its place. This usually involves bolting it into place and then connecting the necessary hoses and tubing. Finally, you’ll need to reconnect any electrical wires that were disconnected during the removal of the old emissions system.

Coolant hose routing for an LML EGR delete

The coolant hose routing for an LML EGR delete is relatively simple. The main cooling hose will come from the radiator and will go to the water pump. From there, it will go to the thermostat housing, and then back to the radiator. There will also be a small bypass hose that goes from the water pump to the thermostat housing. This bypass hose helps ensure that the coolant circulates properly even when the engine is cold. Finally, there will be a return hose that goes from the thermostat housing back to the radiator. This return hose ensures that any excess coolant is returned to the radiator so it can be used again.

Tips and tricks for installing an LML EGR delete

When installing an LML EGR delete, it’s important to follow the instructions that come with the kit. In most cases, these instructions will be fairly straightforward and easy to follow. However, there are a few tips and tricks that can make the process even easier.

One tip is to use an anti-seize compound on all of the bolts that are used to secure the EGR delete kit in place. This will help prevent them from seizing up and makes removal much easier if it’s ever needed.

Another trick is to use a vacuum pump to test for leaks after installation is complete. This helps ensure that everything is properly sealed and there are no leaks in the system. Simply connect the vacuum pump to the inlet and outlet of the EGR delete kit, and turn it on. If there are no leaks, the system will hold a vacuum.

Finally, it’s always a good idea to keep an eye on your engine’s temperature gauge after installation is complete. This will help you ensure that the coolant is circulating properly and that the engine is not running too hot. If you notice any unusual behavior, be sure to check the hoses and connections to make sure everything is still tight and secure.

Remove the factory coolant hose from the EGR valve.

Using a pair of pliers, remove the hose clamp from the factory coolant hose.

Carefully pull the hose off of the EGR valve.

Install the provided coolant hose in its place.

Secure the new coolant hose in place with the provided hose clamp.

Reconnect any electrical wires that were disconnected during the removal of the old emissions system.

Start the engine and check for leaks.

If everything is installed correctly, there should be no leaks. If you do see any leaks, make sure that all of the connections are tight and secure. Also, check the hoses to make sure they are properly connected.

Monitor the engine temperature gauge after installation is complete.

Make sure that the engine is not running too hot. If you notice any unusual behavior, be sure to check the hoses and connections to make sure everything is still tight and secure.

Route the delete coolant hose between the turbo and firewall.

Start the engine and allow it to idle for a few minutes. Check for coolant leaks and make sure the hoses are not kinked or pinched. If everything looks good, you can proceed to the next step.

If you have a manual transmission, put the car in gear and gently rev the engine up to about 1500 RPM. If you have an automatic transmission, put the car in drive and gently rev the engine up to about 1500 RPM. Hold the engine at this RPM for about 15-20 seconds, then let off the gas and allow the engine to return to idle speed. Again, check for coolant leaks and make sure all hoses are routed correctly.

Shut off the engine and allow it to cool completely. Once the engine is cooled, check the coolant level and add more if necessary. Start the engine and let it idle for a few minutes. Check for coolant leaks one last time. If everything looks good, you can take your car for a test drive!

Secure the delete coolant hose with zip ties or clamps

so it can’t move and possibly come off the spigot. You don’t want any coolant leaks.

Remove the radiator cap to help release any pressure in the system.

Using a catch pan, open the petcock at the bottom of the radiator to drain it. If your car doesn’t have a petcock, you’ll need to remove the bottom hose from the radiator to drain it. Loosen the hose clamp with a screwdriver and wiggle the hose off the barb.

Once all the coolant has drained, close the petcock or reattach the bottom hose (be sure to tighten that clamp!).

Fill ‘er up by pouring clean water into the radiator until it reaches the top of the fill neck. Do not overfill it—you’ll need to leave room for the expansion tank.

Put the radiator cap back on.

Now, start the engine and let it run until it reaches operating temperature. Doing this will help flush any residual crud from the system.

shut off the engine and let it cool completely. Now you can remove the radiator cap (carefully!) and check the level of your coolant mixture. Top it off if necessary, using a 50/50 mix of water and antifreeze. Replace the radiator cap and you’re good to go!

Reinstall the factory coolant hose on the EGR valve.

The hose is held in place with a small spring clip. Be sure to reinstall the clip or the hose will eventually come off and cause a vacuum leak.

Reinstall the upper radiator hose to the thermostat housing. The hose is held in place with a spring clip. Be sure to reinstall the clip or the hose will eventually come off and cause a coolant leak.

Fill the radiator with coolant and start the engine. Check for leaks at all of the connections that were disconnected.

Once you have confirmed that there are no leaks, you can proceed to the next step. If you do have a leaking connection, make sure to fix it before continuing. Next, we’ll move on to testing the EGR system.
