I think the water pump is one place I haven't been yet. Thermostat is new - changed it on Saturday to an 82 degree unit as I thought the 92'degree one in there was a bit much, but found out afterwards the gauge was up the **** as well.
Might run some restore (or the car equivalent of it) through the system, flush everything out, drop the water pump, fan and radiator and see what I can see.
Thanks for all the help and support guys, I really appreciate it. :)
For cleaning the cooling system on the brown Merc, the Merc gurus recommend crystalline citric acid. The Merc is a all alloy six.
Works well too ;)Quote:

Well, back to this for one more crack before I put a match to it... 😉
Put some fresh fuel in it, connected the battery and it fired straight up after sitting for 18 months, so that’s a good start. Drove around the block to get everything free - all good apart from no tacho and no charge - not sure what’s happened to the alternator but that’s just one more thing to add to the list. 😁
Gave it a quick hose down to get rid of a few spiders and I’ll make a start at getting the radiator out and everything accociated with the cooling system out as well - water pump, thermostat, fan, hoses - everything. Bit of a PITA job as I need to remove a very heavy bash plate first to get the rad out, but it must be done. If I can get it sorted this time I’ll make the effort to finish it off and start driving it again.
Well didn’t the planets align tonight...
Putting a list together of everything I need - Altenator, stepper motor (mines been stuffed for a while), water pump, etc, etc and a chance text ended up with me at another forum members place looking at a Disco he’d bought for panels. I ended up buying the whole engine, rad, etc, etc off him so I have a spare motor as well all for around what I’d have paid for the bits and pieces I needed. I do need to liberate it from the engine bay however, so have a days work to do in the next couple of weeks, but it will put the Rangie back on top of the list now. 👍
Can you drive it ? You might be able to just stick the entire thing straight into your car if it runs really well!Quote:

At least I'll have a couple of options now. [emoji106]
Rear main ... urrggghhhhhh.... I suck at fitting seals, so I'm always wary of rear mains as if I don't get them cleanly installed..... I'm doing everything all over again the following weekend including a new clutch :(Quote:
