Thread: Disco TD5 overheating

It sounds completely logical and about right for a TD5 10P engine that hasn't had a head job.
That said the quote for $6500 should include a new head.
There are some dodgy businesses in Perth that will maximize their profit at your expense.

Feel like going up to Geraldton? Whyatts are one of the few honest dealers /specialists that I have found in the West.

Typically the head has moved thus pressurising the cooling system causing most of your issues the next thing is if the wrong coolant was used the oil cooler will be corroded causing its own isssues.

I've recently replaced the head on my D2 following a blown head gasket but did the changeover myself.

The indicators I had were:
small amounts of coolant loss - maybe 1 cm in the expansion tank after a couple of days.
pressurised top hose after a hard acceleration - puddling around town didn't seem to cause this. The top hose was much harder and even looked more inflated than usual.
hose leaks - initially from the bleed hose from the radiator to expansion tank. Once that was fixed the next leak was at the water pump outlet.

When I realised that I was just chasing leaks around, and the system was obviously pressurising the inescapable conclusion was the head gasket was gone.

Based on that experience I'd say from your problem list that your head gasket has failed. There are a couple of other worrying signs there - if you aren't seeing creamy oil on the dipstick after driving there is a good chance you are getting diesel in the sump. This could either be just the injector o-rings or it could point to a cracked head.

Looking at the quotes you've got I'd cross number one off the list. These guys are just messing about.

Quote two sounds reasonable IF they are going to replace the head not just skim the head and replace the head gasket. A new head is around $3500 if sourced locally. Factor in $7-800 for head bolts, gaskets, consumables plus labour on top of that. A full set of hoses is around $300-400.

Quote three sounds like a bit of a joke. You mentioned the radiator and heater matrix were replaced in previous work in the last 1000km - why on earth would you replace them again???

You can source a new Td5 head with fitting kits from Turner Engineering in the UK for around $2700AU landed - that includes paying gst and handling charges to courier company. I had the parts within 4 days of ordering.

If you wanted to try and save yourself $1500 you might want to ask if the mob that gave you quote two would be prepared to work with a head and parts you supplied. They might not be keen but it's worth checking.

If they are happy to do this have a look at the Turner site here:
TD5 engine parts TD5 cylinder heads, pistons, bearings

I bought the following items which left about $50-60 of assorted gaskets, bolts, and o-rings to do a "by the book" head change.

LDF500160 TD5 Cylinder Head - early
TD5 Cylinder head fitting Kit (you need to check what gasket you need by looking at the front right of the head - you should be able to see a flange on the gasket and there should be one or more punched holes visible. You would order a kit with same number of holes)
LBF500020 Kit cylinder head

Overheating continued. Leaking heater hose disconnected and blocked off.

Perhaps not much to do with your overheating, but, when you disconnected & blocked off the heater hose, does that mean you bypassed the heater, or just plugged the hose. The reason I ask is, if you just plugged the hose, you have interrupted the coolant flow to the fuel cooler, and disrupted the coolant flow in your vehicle. could make a difference to the systems efficiency.

The lines immediately after the one you've quoted say:

300km later

New heater matrix fitted.

I'd imagine the hoses were reconnected after fitting a new matrix
