I've also saved a few D2's with basically the same line aka previous owner dumped $$$$ into it and still overheated. Popped the hood and found the original thermostat clogged with dexcool goo and the thermostat wouldn't open...... 2k in HG work and no one bothered to replace a 35.00 thermostat. I've seen it many many times! It could be something simple or it could be a fried engine.

 

well will see I’ll check for basic signs I’m not sure where he took it to get this work done but sounds like they did everything and it’s still overheating.
here is the ad and what he says


Runs rough and overheating after a few weeks
Black leather, 7 seater
New thermostat
New radiator
New radiator fan
New clutch fan
Tune up
Oil changed
New hoses
Spark plugs
Air filter
Machined head
New head gasket and bolts

Give me an offer

 

New water pump is missing from that list. You should be able to tell something about the pump function from the flow back into the reservoir bottle.
If the current owner is relying on the dash gauge to say when the engine has overheated, bear in mind that there may be some issues that have arisen related to that after the head gasket work was done.

 

yes good point. He did say the gauge on dash is what’s telling him it’s overheated.
I’ve been trying to ask if coolant drips on floor or just disappear but he’s not answering
I find these days people that are selling used Cars don’t provide information your asking and get annoyed

 

Disco even with cracked block or blown hg will not overheat if there is coolant in it and the cap is one turn loose, except when the thermostat is stuck or radiator plugged.

 

kinda hoping it’s a stuck tstat if it’s a cracked block I would think the coolant would be spewing out to overheat in 15 min.
