Thread: Another 300 tdi overheat!

Loving the visual of "funny noise, car seems to be dying - so put the boot in "
Hopefully the loss of power wasn't the pistons starting to make friends with the bores or you will be up for replacing more than a head.

Expect the worst but hope for the best.

Replace the offending part, fill her up with water and start her up (no pressure cap on) and hope for the best.

Don't call her bonnet a hood again though, you know how fussy these pomms can be, especially if mis identified as a yank. She might crack a woobly and spurt water around.

By that I assume you mean seizing? I have got to the car and checked, I still have free rotation of the crank so no seizure thankfully.

Yes - that's what I was meaning. If its turning over OK then its not seized solid at least.

As Deano said - sort out the hose and see how you go.

Surely with loss of coolant at 100kph it would have overheated and the head gasket will be stuffed?

ALL 300 TDi's should have
engine monitor needs to be fitted
$149 would have saved $900+

Should be all tdi200/300 over 300k need the monitor. In hindsight the early signs should be overflow tank split or a little higher heat on the gauge get the bloody thing checked.I wonder if this would be a problem on a non-turbo engine with the lower egt's???

Nothing to do with having a turbo, but everything to do with aluminium head and cast iron block in my opinion.
Blow a hose on a 80's/90's Falcon and you've got exactly the same result. Same deal with the old Nissan Bluebird I had 20 years ago.

Run out of water on an old 60's vehicle with cast iron head and you pull over, let it cool down a bit while you find some water to put in (creek, roadside puddle etc), in with the water and away you drive.

Also, the youngest production 300tdi's are nearly 15 years old now, so if they still have the original coolant hoses......
