So Land Rover are telling me that diesel can

So Land Rover are telling me that diesel can get into the coolant via faulty injector seals. Is this everyone else's experience.
Just want to tap into everyone experience
Cheers

Td5? I thought that was into the oil???

**djam1** · 25th April 2018, 07:01 PM

The injectors have 2 seals that fail the copper washers that seal against compression and the O rings that keep diesel from entering into the engine oil
Diesel can enter the cooling system via the fuel cooler or cracked head.
IF diesel can enter the cooling system from the injectors I would like to hear an explanation as to how this happens

Don't see how it can do that. Only place I can think of would be in the fuel cooler.

As djam1 said Fuel cooler or cracked head.
Guess which one is most likely

**Chanoo** · 25th April 2018, 07:55 PM

Yes, I knew you blokes would have a better idea of what the go is. Thanks

Yeah isolated the fuel cooler and still have diesel in the coolant, ☹️
So a new head and a few $$$$$ to spend
Good news is, I told the boss and she took it better than I expected, so it's not all bad

Before you buy a new head.
Make sure it is diesel in coolant and not oil.

Here's my coolant

If that photo is of the diesel sitting on top of the coolant, & the coolant is plain water, then that explains why you have issues with the cyl head.
Critical that you use OAT Coolant in the TD5.
