Td5 turbo problems [Archive] - Australian Land Rover Owners

Hi guy's, a friend of mine with a Td5 has had a problem. We were on the sand loaded up and it very suddenly got very hot, coolant spilt from tank, the coolant was green(problem?). After we got off the beach we also noticed that the turbo has cracked on the exhaust side around one of the bolt's that hold it together. Performance is still good and they drove home from Port Macquarie to Newcastle without further problems.
It's a 1999 TD5 disco auto, completley standard.
Any thoughts on what to do with the turbo? , coolant?.

G'day john

Coolant sounds fine bein green as that is the normal colour of glycol coolant..

As for it suddenly overheating id be susin the cooling system and get it pressure tested and have the rad man put his sniffer in the rad to check for combustion gasses to see if the head gasket is leaking ...

Do you know if the head dowls have been replaced as im sure the std jobbies are plastic and have ill effect on the head gasket seal ...

As for the cracked exhaust maniold/turbine housing that has probably happened with the heat from it cooking and spewing all the green coolant ...

Id be verry sus of this eng now and would have the rite people look at it as this could be the start of a major problem if not sorted quick well worth a drive to dungog or else were with knowlage of the td5

cheers

TD5 engines are supposed to have OAT coolant, not green glycol.

I can't comment on the turbo crack but as Chris says, it's possibly due to the coolant quenching it.

Ok wats tha difference between OAT and Glycol:D:D:D

As i thought the green stuff was rite for the td5

No expert here but from memory if OAT and glycol coolants are mixed together it will make the radiator rust away.

Same think that happened to george 130 isn't it?

Yes,
TD5's are supposed to have OAT which is Red.

not sure on the differance either but its the same in our cummins engines.

only allowed the red stuff??

it is possible to get the crack welded up, but! it wont be easy and the ongoing problems could cause a pain in the bum..

as for how the crack got there?? sounds like something might have been loose? this could have caused the overheating? and or the crack?? exhaust gasses escaping at the manifold, making the ecu feed in more fuel???

Mixing them or using the Glycole will kill you cooling system. It will cause electrolosis with the aluminium and once the head goes the combustion gasses will speed the process up even faster. I would suspect the turbo cracked due to sudden temp change and may be weldable but probably better to replace it, Try talking to a few mechanics on that one. With the coolant if it's not OAT get it out ASAP and flush the system till you are certain and then flush it even more, This is a must. After that test its performance with just water and if things are OK fill it with the OAT.

PS
I took 12 months to find the real cause of all my woes.

if thats the case why do you buy them brand new with green coolant??

Some OAT coolant is green but most are pink. You must have OAT or you will pay the price I did.

sorry to be PITA, but if its pink is it definitely OAT, I'm having a ****load of trouble sourcing new coolant.The only place anyone seems to have heard of it is on this site, cant get any satisfaction from any franchise within a 3ookm radius.And on another point, mine has been running green stuff since new, so can I assume its OAT and just flush it and add the pink, or should I assume LR predelivery is as good as their warranty and fear the worst, that Ive been driving around for 50000kms on the wrong coolant??

Crump just be 110% sure the old coolant is completely out of the system before you replace it. The electrolosys not only permits rusting but also creates a goo inside the cooling system that blocks it.

For the record I have heard of some Japanese manufacturers having the same problem.

Supercheap has Nulon OAT which is ok

Normaly would agree but The tank is on the oppisite side of the engine bay. They had a new radiator put in recently by Natrad, would they know what they are doing with the Td5? Engine is not making any strange sounds? are Td5 turbos Expensive?
Thanks for all the replies guys i'll pass on the info.

OAT coolant is Organic Acid Technology. Most of the big names sell a coolant of this type now (eg Castrol Antifreeze SF-O).

As for a radiator place knowing... not necessarily, depends on how on the ball they are. Whilst this coolant isn't just for Td5's its not as common as the old Glycol and so they may just have gone with what they thought was right.

or......

if it came to our workshop it would have got the green stuff......right up until shell took over from castrol.....

from that date it would get the red stuff......

what im saying is......some places just dont care......and the customers usually have no idea.....

the mechanics may know what should be in there....but dont have a choice as to what is actually used......
they just have to use what they are told to use.....and how much.....
i see it every day.....and am forced to do it myself.....

red and green even get mixed together because the system doesnt get flushed.....just drained and filled......
yes this sort of thing happens all the time.....the boss says you have half an hour to do the service and coolant.....the drain plug comes out of the radiator.....
the sump plug comes out of the sump and the oil filter is replaced....then when the liquids finish draining....the plugs are refitted......
and the cooling system is filled with a couple of litres of coolant(if enough drained out )....if there is more room...it is topped up with water.....
doesnt matter what colour came out or what goes in....the sump is filled with oil and its all done...

as far as the customer knows.....its all been taken care of....the mechanic knows what needs to be done
but has no choice if he wants to be paid........and any damage to the cooling system wont be evident for a year or so.....

ok...now you get the picture....ill say it in plain english.....

if you want to know what goes on with your vehicle....you need to do it yourself......
or find a mechanic that actually cares......usually one that works for himself......

this is fascinating. In the TD5 engine life thread we saw that radiators typically died causing overheating after a few years. Reading this it sounds as though the real cause is people putting in the wrong type of coolant. Fascinating. :eek:

OAT, I'm having a ****load of trouble sourcing new coolant.
HAVOLENE from caltex DISTRIBUTOR,
around $40 for 4 litres,,

though I only bought it for a top-up
not sure if ONE is enough for a complete refill:angel:

and yes,, V8s and TD5s use the same--;)

I know the Canberra NatRAd guys who recored my radiator had never seen the TD5 radiator before. They even thanked me for letting them do it. I droped it of and colelcted it as the rig was at home so I chose the replacement coolant but the guy did warn me that they found a lot of gunk from mixed coolants in it.

Isn't it incredible that so called professional's will happily tell there staff to do the wrong thing. Even before i came to this site and never knew the difference between coolents, you would never catch me mixing two different types, not even two different brands of the same type without flushing the cooling system first. Very disturbing to hear.

If you are not sure whether you have OAT or glycol coolant, there is one available that is compatable with both.
It is Prestone brand and I believe sold by the majors.

Hi Crump
Do you have a Shell dealer in town!!!! Shell to an OAT coolant as well as Caltex.

Interesting, I presume they give a written guarantee that covers an engine recondition ------------------------------------------------------------------if it doesn't work?

Hi guys, well it appears that the problem is oil in the harness, Landy andy i have searched for your thread on flushing the harness but can't find it. Do you have a link as we might be able to give it a go. Do you need to still replace the injector harness or can you flush that too.
Around what kind of $ should they expect for the harness.

LandyAndy

2nd February 2007, 06:29 PM

Hi Wortho
You have PMs.
You need to get the new injector harness,its causing the problem.$300 MAX depending on supplier,check the site sponsors,dealers will sting you BIGTIME.
www.karcraft.com.au (http://www.karcraft.com.au) are my favourites for parts ex east.

I now need to get my glycol coolant out but can't do this until Friday - car is not being driven at the moment so can I expect any damage if it is left until Friday?

glycol can be used in the td5 BUT its a lot more maintenance intensive than the OAT.

you must thoroughly flush the engine's cooling system when you change OAT or if you dont know what is in it before you put OAT in. all the bad things mentioned above can happen if you dont..

I personally use the Nulon OAT that comes in a concentrated 5l bottle that you mix down with distilled water. when you mix it to the maximum reccomended percentage it leaves you just enough in the bottle to make up some premixed ready to go OAT coolant and the ability to (if needed) add up to about 2l of distilled water to the system to get you out of trouble if you have a minor leak.

some words of warning.

Pure H20 is better than
glycol that is too strong
glycol that is too weak
OAT that is too strong
OAT that is too weak.

so..

IF you are in an emergancy situation and have lost your coolant you are better off to flush the whole system out with as much water as you can before filling it up again. Last time I did big red it took 3 fills/drains to get the all the coolant washed out so I could refil it.

soz to ask if some one allready has, but castols blue coolent, witch is that, ??? is it a good coolent

I was getting my Disco II serviced at Range-Rov, and one time (when they were running late) it came back with water in it, no coolant. I took it back soon after (for other re-work as usual) and they tried to tell me it wasn't water, then when they worked out I wasn't blind, they tried to say someone else did it (no else touched it), then they got frustraated and said they would look at it.

When they returned it, there was coolant in it (amazing), which they charged me for, and, the icing on the cake, they charged me for disposal of the old coolant.

What can I say......
Thats when you go off your rocker in the service department and if you don't get what you want and it's a dealership you go up into the show room and start yelling at them over it.
Demand written guarantee that they have not damaged the vehicle and a full refund for the service.
Thats if your nice. Other wise take it further and do your best to send them broke. If they are nice you play nice. If they lie and cheat then fight back hard.
Mistakes happen but hew they deal with it says a lot about their customer care.

You could do what I do and take it to a specialist who will do a chemical flush that will remove all contaminates and old coolant from the cooling system including the heater matrix and replace the coolant and pressure test and do the job right.I do all three of my vehicles every year without fail and have never had a cooling issue,long life coolant be damned,every year and the D1 and fender get green Glycol and the L322 gets OAT.It costs me $110 each time or if the rad gets rodded,every third time,it's $240 and $24 for the thermostat..I have no idea why people on this forum risk thier engines for that amount of money.
