Thread: ENGINE GONE 172000ks ANYONE ELSE??

Correct me if I'm wrong

but isn't there a design issue with the sensor on either 200s or 300s? Maybe both?

Basically its very high in the system. Any coolant loss & its running in vapour, & won't detect rising temp quick enough?

My memory from when I had a 200 is that TDIs have head gasket issues about every 160,000 kms normally, and any overheating just compounds the issue.

The TD5 apparently has the sensor near the water pump

Alot of problems in my opion can be avoided by simple maintenance.Parts in vehicles don't last forever and it's like the thread about the serpentine belt going after 100000km's it should never have got there.Belts are cheap,thermastats are cheap,radiator hoses but all do a very serious job,if they stuff up it's a nightmare and for what,a couple of hundred bucks.LR don't have a service sheet for nothing.

You are right there Pat, however most of these parts don't have a life against them or fail to meet that life.

Serpentine belts going to 100k is great and changing them at 80k is recommended however if you do change the belt, I found that the tensioner would then stuff up and kill the next belt early. Water pump seals shouldn't fail and these aren't listed with a life. I will agree on the parts price though, cheap enough to replace with gen parts. I got my water pump for $88 and lower hose for $94 and these were from LR. People also tend to forget the heater and ancillary hoses.

Land Rover listed the timing belt at 100k but most say change at 60k and I change mine at 80k. Ford did the same with lower ball joints until 6mm play was within spec's.


Simple maintenance? I go through the car each week checking things like oil's, water, lights and a general look over at the hoses etc. However I still failed to notice the water pump seals leaking and there wasn't water under the car when I pulled up. Mind you there aren't oil leaks either

Not having a shot Pat but most of those items aren't listed in the book.

One of the best things I have is the Haynes manual.Step by step on servicing and what to check.The other good thing is this Forum.How many things has everyone learnt on here? Pat

I had a persistent leak somewhere in the cooling system that would only rear it's head on really hot days overtaking or going uphill. The temp would slowly but obviously start climbing until you backed off.

Turned out that there was a small leak from behind an alloy casting (someone will no doubt be able to explain this better!) which the water pump etc bolt through. Apparently this was added to the 300tdi to make changing timing belts easier.... (Hmm already suspect were they? LOL) anyway turns out the water pump basically holds this on and there is a gasket behind it which if the water pump isn't tourqued up correctly and evenly (yes... quilty as charged) it can crush this and leak. Not easy to see looking over the engine until someone points it out to you. Just a warning to others if you can't find where the water is going or fix an overheating issue, might be worth a check.
AND GET A LOW WATER ALARM..... NOW

cookiesa you are talking about the pistol gasket I think.Every 300tdi owner has replaced one of them.Get ultra blue sealant and new plated bolts when you replace it and do them up evenly. Pat

My Landy man was the one who told me about it after I told him about the persistent tiny amount of water it was loosing and the running warm under specific conditions. He knew straight away where to look. Unfortunately he is nearly 400km's away so don't get to let him look often enough
