Hey guys, yes i did search. The new Search function doesn't seem to work properly. I type in 'overheating' or 'over heating' and it comes up with barely anything.

My NA R33 seems to be overheating when heading uphill. At one point it got close to the H so i had to pull over. It's fine in town however after a long drive and heading back into town it can be a little bit hot. Turning the heater on helps settle it but not when going uphill.

Have replaced radiator cap, thermostat, and flushed radiator.

Note: Car also takes quite a while to warm up.

My money is on failing water pump, but i really hope not.

even if the water pump is failing it should still heat up in a matter of minutes when driving (if you are on of the people who let it sit there and idle until it is warm, then it will take much longer than if you are driving).

i'd say that your radiator is probably quite blocked (which a flush won't do a thing to fix).

you can sort of check. connect a hose as air tight as you can onto one end of the radiator (i suggest fitting your cap and clamping the garden hose with the fitting on it to the radiator hose) then run the water. you'll notice if the water comes out fast enough or if there is heaps of pressure in the radiator hose you connected your garden hose to. thats just a back yard inspection though.

      New fix for low tyre pressure from bmw

      I believe Unimog is the only vehicle that has it (from the manufacturer). I haven't seen aftermarket permanently connected kits, but I haven't looked either.

      Ha ha ha, can't overthink when exhausted... Oh how I wish I had that power! I can be absolutely dead set shot, and my brain will still go "we need a good 3 or 4 hours to just think about everything and anything before you may sleep... My biggest thing is making sure I give myself enough sleep. I don't operate on even 7 hours of sleep! I attempt to give my body 9.5hours sleep a night to be able to function. I don't sleep the whole 9.5, but I need to make sure I offer a big window. I also take a single supplement, which is to help with long term health, and fighting inflammation, and I notice it helps massively. Especially me sleeping, and just less "achey" in the body. Have also kicked sugar, and gluten. A majority of people with ADHD don't go well with gluten. It causes a really interesting natural opioid overdose in the brain, which causes bodily issues and sensory issues.

      Yeah that's what I meant, permanently connected not manual

      Yep. But typically that's just run a hose down to the tyre while stationary.   Oh and the Unimog will automatically air up and air down tyres from the onboard computer for you too.

      There was a good video somewhere, maybe Kurzgesagt that linked physical activity to ADHD/Anxiety/Insomnia etc. Basically the body WILL spend energy doing something if you don't spend it doing anything physical. It isn't fun, but I personally have noticed I've never been overthinky, or unable to sleep if I'm physically exhausted from doing a lot. The musings around it seem to indicate that this is one of the reasons/mechanism that physical activity improves mental health/wellbeing etc, by more or less not using that 'extra' energy to overthink, be anxious, inflammation, etc. There's also the fact that every obnoxious exerciser ever says it's great and helps which is extremely annoying. Like people who say the same thing about travel being the best thing ever. I mean, they clearly are, but blah. I started doing a LITTLE myself (think 3x15min per week) and honestly did notice the benefits, aiming at life quality when older. Which is sooner than you think. Getting something into your routine that you can actually make a routine has helped me at least. This post brought to you by procrastination between sets.
