Thank you, really helpful video. I'm getting increasingly braver at undoing bits on my Land Rover thanks to you. we could all do with two vehicles, one to practice on, one to drive. Thanks again for being the 'practice on' vehicle.
hi Use a concentrated flushing agent .Typically 1--2 cans some has to be dissolved prior , drive for 15mins to get properly circulated and to get well agitated . This will absolutely strip out all corrosion and dirt . Needs to be well flushed and radiator core diss-assembled for internal cleaning. Use a pressure cleaner on overflow bottle . Flush heater core .
Great tips there! I am about to do this job on my TDI 300, I am toying with the idea of fitting an alum rad rather than the copper one, would it be worth fitting an alu or just replace it with a copper one?
Quick one. I removed the red coolant from my system, flushed with water twice. So basically filled the system up twice and run the engine both times. Then refilled with millers blue which is the correct coolant. However my header tank fluid looks brownish colour already. Def no oil in coolant, head gasket is fine. Have I flushed the system enough as to not mix the two??
Just dipped the header tank and rinsed into a cup and it is still a very light pink? Old coolant originally came out pink with a few small metal particals. But I did a 50/50 mix, if it was rust surely the coolant would appear murky, where as this was quite clear.
Good question. Unless you live in extreme conditions, there is no point having a larger radiator unless you are doing something really specialist with the vehicle. The best efficiency you can get with the engine is to have it and maintain it at running temperature. Cooling system design is already efficient. Aas long as it is kept in good order should there be a reason to change it?
hi I want to flush my discovery 1 300 tdi coolant system through and replace all coolant. what's the best way to do this please ? through the thermostat? is it just a case of flushing through until all comes out clean. refilling (how much coolant? which coolant?) then running with the heaters on and cap off expansion tank until bubbles stop... squeezing hoses to remove all air? thanks Jesse
hello. I got a 300tdi in a d1. had head off and I'm starting to get heat issues intermiddently. the was a composite gasket on It and when it was scraped off some may of fell in. you think that this would get rid of it?
and yeah. it was serviceable. it first started when I bounced over some crap when I went bush. ive replaced the thermostat and its still on and off. so that's why I reckon its a foregn body in the system
It is a possibility that something could be blocking a water gallery. I could' hazard a guess as to where it would be blocking but the narrowest parts are where the head gasket is Gasket restricts some of the flow to the head.arounf the cylinders.
4 years on this video is still my reference point when I change the radiators on my landrovers. Cheers!

Glad it is of help. That is our main objective.
More frustrating with A/C!!
Great video as usual.

Don’t start the project unless you have o-Rings for the oil cooling lines. Also get a 3/8 hose for capping the oil lines as well.
Great video! Do you happen to know the torque required for the coolant drain plug on the side of the engine?

only cost makes the difference. Copper on can be repaired.
You briefly mentioned the drain plug on the engine block, Can you tell me where this is exactly. Thanks in advance.
th-cam.com/video/R66rW8LO4nc/w-d-xo.html same place as the 200tdi engine. see in video link
Thank you.
Is the thermostat needed for warm climates? located in jamaica
What is the size of the nut on the fan clutch? 36 or 40 MM, perhaps?
32mm on the 200tdi and 300tdi engines.
Why can't I find a good on how to changing and flushing a D1's coolant system!
+Country Brothers Outdoors Because?

Sam Bam not if you have flushed it properly. Could be rust?

Good day ,
Can you upgrade your radiator like you would a inter cooler, and would it make a change to anything?
Thanks

How many coolant i need for my 2800tdi for 50 - 50
Hola amigo!
Quick question 300tdi> always blue coolant? Never red? Thanks a lot
Not red. That is for later engines.

Didn't i say all of that in the video?
I just wanted to check if it was the same on disco...
It sure is. Good luck!

sorry not quite understand what you have written? Gasket fell in where?
have you checked the head condition? th-cam.com/video/oTi6B7VNE7U/w-d-xo.html
in to the cooling system when I had the head off
and yeah. it was serviceable. it first started when I bounced over some crap when I went bush. ive replaced the thermostat and its still on and off. so that's why I reckon its a foregn body in the system

please change the batteries in your smoke detectors all i can hear is the chirping
+matty schofield You should be listening to me! I had to call out someone to replace the whole lot. It was faulty. All good now.
Good 👍👍👍👍
Sorry, it's a 300tdi defender.
