Yep, I usually just check the manufacturers requirements and if the oil I have either is the same or surpasses those requirements I'll use it. There are good mineral oils too of course but I usually use the synthetic one we buy for cars since me and my parents are using the same oil for all our cars so simple and easy to buy a big 20 L oil drum, it fits the requirements for all of them.

Yep, that's where I drained the coolant.

Is that the drain plug on the hose on the right side of the engine? I used that one to drain I meant a drain plug specifically on the engine block when I was talking about not finding a plug. I assume there isn't one.

Yes, mostly. I was just using it as an example not as an idea I'm going to do to my car, that would need a lot of work. I've seen it be used on some tractors though however instead of brake fluid. Yep, I had a citroën previously where I thought hey ill change the transmission oil it's probably never been done and out came some white sludge because water had gotten into the transmission. I'm happy I did that. I usually buy synthetic oils. I usually don't use the original manufacturer's oil either I've got my place where I buy oil from so I use the same brand for all my vehicles. And for cars I've only got one oil for the engine and it is synthetic and should work fine for this one.

I always change my oil every year or every 10 000-15 000 km whichever comes first, and always drive it warm before I drain the oil. The old oil wasn't that good either, probably hadn't been changed for a while so I'm happy I changed it pretty much the first thing I did. I didn't really find a drain plug on the block for the coolant so I didn't manage to drain through there sadly, but I needed to get the car working and it's working fine now actually a little bit better than before even I'd say. But when I have the time I'll do a more thorough service, my biggest priority is probably brake fluid then power steering and transmission oil. I'll have to check up on wheel bearings and brakes, etc. as well when I'm at it but I've got a bit too many projects going on at once but hopefully I'll finish one of them soon.

I've driven it a few times now today and it seems to be working quite well, it's keeping cool and also heating up quickly. So the new thermostat seems to work fine, and the hose that was leaking earlier is also keeping itself sealed which is good. I'll probably change coolant again when I change the oil next time because of all the dirt there was in the old coolant, I did try to flush it out when I changed coolant but I didn't really notice much residue coming out and the water I flushed with looked very clean, so hopefully it got most of it out when I drained the old coolant.

I understood it was a typo and understood you meant dot 5 😁. I'm not using original coolant I'm using valvoline hd extended life coolant as it was what I had on hand.

Yep, I'll have to check if I might change to dot 5 then, I always found brake fluid (dot 4) to be stupid, why would you ever use anything that absorbs water but there's probably a good reason I assume but seems like dot 5 or for an example LHM, although that would require changing the seals.

I'll think about changing it to DOT 5, as I don't have ABS, but you do need to change the seals then right if I don't remember wrong? Because I really hate working with brake fluid because spilling it anywhere is hell. The coolant that was in it I don't know really since it wasn't the best looking the color was a bit off, it probably wasn't original either as it wasn't really blue/green, red or violet. I tried to flush out as best as I could the old coolant out of the system with water and I got out most of the old dirt and I also took loose the expansion tank and tried to flush it out and get it as clean as possible too because it was quite dirty and had some sludge stuck in it. It wasn't oily or anything so I don't think it's a head gasket or anything I just think it was very dirty or some coolants that were not supposed to mix put in there, which was why I wanted to change it and flush it out.

Yep, that's where mine is as well, sorry I was a bit unclear but it's keeping itself around the line in between 70 and 110, just like in your picture. The tyres are good I checked them when I bought the car. Lots of people forget to change brake fluid so I am going to do it as soon as I have time to do it. I've worked on some vehicles where brake fluid was probably barely ever changed and it can get really sludgy and break a lot of things..

I don't know exactly when it opened, but that was when it dropped in temperature, which is why I said so. I might've been a bit unclear sorry.

Yeah, I was planning to change brake fluid and servo steering oil as well, but I'm gonna do those later as those were in better condition and right now I have other projects that I need to finish. I changed the clamp to the thermostat housing as that one was leaking, I also accidentally had gotten some dirt between the hose and the thermostat housing which also helped create the leak. I've never actually experienced a cooling system being this hard to get the air out of, closest I've had to being this annoying was helping out with a Renault Master but that actually went fine eventually. I've been planning to keep this car for a while maybe fix up the rust on it eventually, but that is a project for further in the future as right now I'm renovating a tractor and a bunch of other stuff..

It didn't open at 110, it opened between 110 and the middle line in the temperature gauge, which I assume is 90 degrees at first. Now it's at 90 and is behaving like normal no fluctuations in temperature and staying at 90 when I drive, all hoses and the radiator are the same temperature. It never got up to 110 only in the middle between the middle line and 110 degrees. Also I remembered to gently unscrew the expansion tank cap. I forgot which color the coolant sensor was but I think it is yellow.

Alright, been out driving for a while, first it didn't get fully warm but I finally got some heat from the heater, I kept driving it and it did fluctuate a bit in temperature eventually slowly rising to between the 110° and 90° marks then suddenly it decreased to between the 90° and 70° mark. I drove back to the workshop and checked the heat on all hoses and the radiator. Radiator was pretty cold and so was hose from the radiator but the hose to the radiator from the thermostat was hot and the heater hoses were hot. I pumped a bit by hand on the hoses and went out for another drive and it fluctuated a bit but then the fluctuations in temperature became less and less and finally I thought it was keeping itself at about the same temperature as earlier so I drove home and at highway speeds and it kept itself at the correct temperature. So I finally fixed it, thanks for all the tips they helped out a lot! 😁

Alright, I've checked the system has no leaks now, pressure testing it currently and it seems to keep pressure, had a little leak at the coolant hose to the thermostat housing, changed the hose clamp and it seems to seal now. Will try starting soon after having waited for a bit with pressure to see if it goes down or leaks somewhere.
