While working the mpg out I realised that I'd gone past my 6000 oil change interval by a few hundred miles, when I checked I found that the alternator belt only scored 2.5 on the AR tension gauge, so I retensioned it while I was under the car. The picture of the dipstick is after running the engine...

The Zemco fuel computer is still not 100% right on the fuel used side. I did put a lot of effort into calibrating it, but suspect that when idling/on overrun the tiny amount of fuel going into the engine may be more tiny than that going through the return, the journeys with most traffic jams seem to...

Not too bad, wheels easily sorted and emissions might just be crappy fuel, can be a horror to get right if tester is a bit picky tho'...

That would make sense, they would have to make a different one for the diesel, but could use it on everything by altering the top hose , which would be the cheapest part..

One thing you might like to consider is using Evans Waterless coolant, when the waterpump is off you can get most of the water out and clean the sludge out of the bottom of the block, you'll still need to use their 'prep fluid' to get the water out of the heater matrix. It is quite expensive, but should...

Unfortunately the petrol and diesel ones are different, on the diesel the little breather pipe on the top comes out of the front of the tank, as the engine mount is in the way of it coming out of the side. This can be very annoying as they are identical apart from that. I might have a spare second...

GRD 983 is the right one for Maestro 1.6 from 1986 on, it is the same as the Montego, you did well to find that!...

A couple of 'proper people' that are worth trying ahead of ebay are https://www.xjrover.co.uk/ and https://bestofmgrover.co.uk/ . If all else fails you could use an MGF radiator (I think Jeff put a post on here about this). only problem with using it on a 1600 would be that you'd need to extend one...

As far as I remember 1600 radiators are not that easy to find, the early ones were a different size to the later ones and are the hardest to find, later ones come up on ebay sometimes. It might be worth trying to find a local radiator specialist, they may be able to recore it, or find a replacement...

Not long before it is up for sale then, someone is going to have a nice car,

Have you got an accurate means of checking the temperature? If it isn't really too hot it could be faulty temp sensor, ECU, or (unlikely but possible) gauge. Other things worth checking are blocked or corroded fins on radiator and that the water pump is pumping well (heater working well and rad hot...
