▼Parts and Tools Listed Below▼
This how-to video will show you the full thermostat replacement procedure on a Range Rover Sport or LR3. If the thermostat becomes closed or faulty, the engine will be unable to circulate coolant to the radiator, resulting in:
1. Engine overheating
2. Loud fan noise once the engine warms up as it attempts to cool
Make sure to check your coolant level to ensure your overheating is not simply from low coolant.
I have now done this replacement twice on my car over the last 7 years, it's a very common failure point, but luckily it's also extremely cheap and easy to repair. It's entirely possible to replace the thermostat for under 50$ depending on the brand of thermostat you purchase.
➤ Parts required:
Thermostat + O-ring: amzn.to/3lYd6Nq
➤ Tools required:
T25 Torx Bit (for thermostat housing)

This is the BEST "how to" video on RU-vid! You are awesome and your description is very precise and clear. Thank you for sharing your knowledge. FYI the Amazon link for the thermostat doesn't work....greetings from Canada :)

@HazyJay 3 года назад

Thanks I glad you found it useful. Hmmm I think the links act up when they are opened in other countries, let me see what I can do, thanks for letting me know!

@rrshse6704 3 года назад

@@HazyJay Don't worry about it, I ordered the whole thermostat housing assembly from Atlantic British, it will be everything I need because it comes with the temperature sensor as well. I'm not very clear on the bleeding procedure though, I was planning to use the bleeding valve on the expansion tank. Any thoughts? or advice how to do it properly? Thanks!

@HazyJay 3 года назад

@@rrshse6704 Soooo bleeding the cooling system is kind of a subject of contention for whatever reason. I filled the tank to the full mark, ran the engine until the thermostat opened (temp gauge at it's typical position showing the engine is operating temp), then turned the car off, let it cool, then filled again to the cold line. I would check it over the next few days and fill it as needed, I only filled it for about 1 day and I never needed to fill it again and my engine runs at the correct temp. That being said, the L320 manual has a different procedure that I will transcribe below if you want to follow that: 1. Remove the coolant expansion tank cap 2. Loosen the coolant expansion tank bleed screw 3. Add coolant to the expansion tank as required, until the upper level mark is achieved 4. Set the heating system to MAX heat, the blower motor to MAX speed, and the air distribution to the instrument panel registers 5. Loosen the coolant bleed screw adjacent to the charge air cooler 6. Turn the ignition key to position 2 (this should run the electric coolant pump), but do not start the engine 7. When coolant runs from the bleed point bubble-free, tighten the bleed screw 8. Start the engine and allow to idle 9. When coolant runs from the expansion tank bleed point bubble-free, tighten the bleed screw 10. Top-up the expansion tank to the upper level mark 11. Increase engine speed to 2,000 RPM and maintain until no air is seen returning to the expansion tank 12. Switch the engine off and allow to cool 13. Fill the coolant expansion tank to the MAX mark

@rrshse6704 3 года назад

@@HazyJay I filled the expansion tank until the coolant was coming off the bleed screw, (overflowing), the I closed it . I sucked out some coolant from the return tank with a turkey baster until it reached the upper fill level. Then. with the tank cap open, I ran the engine until hot with the blower fan at high speed. However I could see just a few bubbles percolating on the return hose, just under the bleed screw ( little tank). I was so tempted to unscrew it and let the air out , but I was afraid that it would be pressurized and would blow hot coolant and screw up the whole procedure. The truck run fine by the way and hot air comes out and no issues with the temp gauge. I'll check the coolant level tomorrow morning and see... Thanks again!

@HazyJay 3 года назад

@@rrshse6704 Sounds like it worked, yeah if you look online people have a few ways of doing it. I've tried the way the workshop manual says and it seemed to work as good as just filling it intermittently during the week, so whatever works haha.

I just had my replaced due to very small leak from the housing. Was thinking to try stop leak liquid but after thinking twice i took it to mechanic. They charged me for 3.1 hours. I asked for the old part, took it home and opened to see out of curiosity. The rubber seal has already kind of melted (main reason for the leak). A plastic round plastic part inside the housing which is touching the spring was also broken.

@HazyJay Год назад

The round plastic bit that touches the spring breaks ALOT, it's a weakness of these thermostats. I wish that part was made of metal.

@metromotel Год назад

mine is 2013 sport @135000km and I live in mild climate. I wonder if they fail a lot earlier in hot countries?? @@HazyJay

@HazyJay Год назад

@@metromotel I'm not sure, but I know fast temperature changes cause most materials to become brittle, you'd expect more drastic temp changes in ice cold environments where you're going from 32F to like 200F as opposed to 100F to 200F

@HazyJay 3 года назад

Someone asked if you need to exchange the metal/spring hardware once you get a new thermostat. You do not need to exchange the metal/spring thermostat parts when you get a new thermostat, the new housing should come with the thermostat hardware already installed. The tutorial in the video is only for if your hardware comes loose and you need to reinstall it.

What can other coz to heating up And what will happen if you remove thermostat from range Rover sport HSE 2009

@raijong_ 3 месяца назад

Hey, I have a Land Rover 2007 Lr3 it’s still overheating and I’ve replaced the thermostat housing already. What else could it be?

@HazyJay 3 месяца назад

Potentially the water pump, low coolant levels, air lock. I would first check coolant level, and if it's normal, perform a coolant bleed procedure to ensure the air is out of the system. You should see trickling of coolant into the reservoir when the car is running, IF NOT, the water pump is likely bad.

@wesmccullough3985 3 года назад

You mention the temp gauge as reading oil temp. Is that accurate? The gauge doesn't read engine coolant temp?

@HazyJay 3 года назад

That would be a mistake, the temp gauge should measure the coolant temperature. The oil pressure is important and the coolant temp is important, less so the oil temp and coolant pressure.

@theaftermarketSHOW 3 года назад

Replaced headgaskets on my 4.2 SC. Mechanic said that they blew. Started up the car and the initial problem is still there , the water reservoir tank starts bubbling over when the car gets to running temperature while its idling. Replace thermostat , replaced waterpump, not sure what else too replace.? Mechinac said , I should buy a new engine.🙄.... and suggestions.?

@Pil215 3 года назад

I changed the thermostat n the housing but i see a crack on my radiator

@johnnyquid3350 Год назад

Hazy, why did you only buy the small part instead of the entire housing? Mine failed, so I bought a new one and it failed after 4 months, so I'm buying a new one from Atlantic British. But its much bigger than just the thermostat part?

@HazyJay Год назад

The rest of the housing was good, and to replace the housing is much more work and requires removal of multiple components. Because of that I just replaced the thermostat part.

@johnnyquid3350 Год назад

Hazy, i have another question, i accidentally bought a cheap thermostat from amazon and four months later it has failed, leaking at the O ring right on top. So im gonna try and replace entire housing AND the expansion tank at the same time. Any suggestions on what order to do it, what tools i need? Do i have to remove throttle body first? I have thermostat, coolant tank, 6 plastic hose clamps so i dont loose much fluid and hose clam pliers for that bottom clamp on tank. Any tips will be appreciated! 👍

@HazyJay Год назад

The hardest part of replacing the entire housing is reaching the bolts that hold it in place, make sure you have extensions for your sockets. Otherwise it's just removing parts top down until you can access the housing. If I remember correctly you do need to remove the throttle body but that's just 4 bolts holding it in place that are pretty easy to reach.

@johnnyquid3350 Год назад

Hey Hazy, I replaced the thermostat and coolant tank and now I have misfires on start! When it warms up it stops. Any suggestions? Thanks Haze 👍

@HazyJay Год назад

Make sure the throttle body (which is nearby) is connected correctly (the wire harness may have gotten wet) and lines are all attached to it. The cooling system shouldn't have much to do with misfires when the engine is cold since the thermostat is closed anyway to let the engine warm up.

@victorfred5233 11 месяцев назад

What if I take it of completely

@HazyJay 11 месяцев назад

In theory it would just be less efficient because it takes longer to heat up. BUT I tried that (because I didn't want the broken plastic/metal getting in the system) and it overheated... I'm not certain why.

@SaultiBalldeip 2 года назад

The thermostat should have a small & a large spring but yours only looked to have the large one?

@SaultiBalldeip 2 года назад

Ah I see your inset pic showing the small spring lol

@arkivezaj 3 года назад

My temperature gauge is not reaching operating temperature it's going to about a quarter up and not halfway like it usually did. Which leads me to believe that my thermostat is stuck in the open position. Also every few days or maybe once a week I'll have a low coolant show up in my dashboard. Not sure if that's the case but would you think it's a thermostat stuck open?

@HazyJay 3 года назад

I would try replacing the thermostat and seeing if that fixed your issue given it's pretty straightforward and would cause failure to reach operating temp. Otherwise you may have a leak further down like in the housing or one of the lines.

@gagandeepsingh9627 2 года назад

Heyy changed thermostat and Water pump and change the belt and still making the fan noise

@HazyJay 2 года назад

It's possible the fan clutch is ruined and will need to be replaced. When the engine is cold you should be able to freely spin the radiator fan, if not, the clutch will need replacement.
