Good to hear!!

Appreciate the kind words. More are on the way! With 3 of these cars in the family, there is always something that needs work.

@@OlisGarage Lol feel yah. I call my mk1 jetta the never ending project.

@@json8172 oh they definitely are. But that’s the fun in it. I did all the major mechanical things in the beginning of ownership (belts, hoses, water pump, axles) so now it’s really reliable and I can focus on smaller upgrades and such.

@@OlisGarage Being they are so easy to work on compared to new cars. Yah, its not so bad. Just 40 year old parts starting to fail.

Flush it well. It might take a few flushes to get it clean, but it will be well worth it.

@@OlisGarage I may have discovered a bad head gasket... got any tutorials on that? Lol.

Not yet..I did the job on my 84 before I started filming.

Good question. I need to make a video on that. It’s from a mk1 scirocco. Part number 171121253. Just make sure that the one you buy has the little feet on it and the coolant temp sensor hole on the side where you fill it.

The steering column has a bearing that usually fails (well the plastic race fails). I will be making a video on that eventually as I recently ordered the parts. Low compression....that requires the typical low compression fix of either new valves, rings, or both. I do not plan on making a video on either of those repairs anytime soon.

@@OlisGarage I will love to see the steering column video when it comes out! your videos are super helpful to watch

@@javanking8681 glad they are helping people!

Alright, you’ve convinced me. I’ll try to film it tomorrow and upload it on the 1st. No promises, but that’s the goal! I’ll let you know tomorrow how far I got with it

Hey Zander Brand, I just got the video completed and uploaded!

If you add the flush additive with the thermostat installed, then you have to make sure it gets hot enough for the radiator fan to cycle. Otherwise it will not flow through the whole system. (Radiator fan cycling indicates thermostat opening). If you can get to everything without removing the power steering pump, go for it. But I definitely recommend replacing your thermostat because it is a mechanical item, and there is also a rubber seal in there. Additionally if you don’t remove the thermostat, you will not be able to fully flush the system with distilled water as it will not be able to flow through the system (thermostat is closed when engine is cold). Hopefully that answers your questions!

Understood. Thank you Oli, I will wait for the power steering removal post...plenty other things to do. Thank you for the fantastic videos!

@@kwilson9828 you are very welcome. Glad the content is keeping vehicles running on the road! More content is on the way. Filming and editing just is a bit time consuming. But my goal is to have a new video on the 1st and 15th of every month. Tomorrow you’ll learn how to properly adjust your clutch cable!

Hello K Wilson, just wanted to let you know that I just got the power steering pump video uploaded. Enjoy!

I’ll get back to you on how high to fill it. I think I have a copy of three scirocco manual. I think. Fantastic question!! I like your thought process. I would do that, and then buy a refractometer. It is a device that can be used to measure ethylene glycol (and also alcohol) content in water. People use them often when they brew beer. With that device you can precisely figure out what your mixture is. I would recommend a 50/50 unless if you live in Alaska or somewhere really cold. But absolutely, use that chart in the Bentley once you figure out your concentration via refractometer. I just recently bought one from Facebook marketplace for $5. Don’t forget, you can always remove a little coolant from your radiator with a small hose and then adjust with water or antifreeze. But then to mix it properly you have to run the car until the thermostat opens. Just something to keep in mind

@@OlisGarage I ended up finding it in my Bentley. One the outside of the fill tube, there are two lines, starting at around 1.5" below the rim. The bottom is min, the top is max. On the inside of the fill neck are corresponding marks, none of which are very easily seen, nor are they explicitly marked "Min, Max, Full, etc." By those marks, I was VERY low on coolant, which would probably explain most of the issues I have been seening (I just bought the car a couple of weeks ago). Thanks for the reply, and the awesome content!

I now use G13 because it’s fairly easy to buy, and then my mk4 and mk1 have the same coolant, so less to keep around the house. Obviously the stuff I removed was g11. I’m not sure what VW changed in coolants from g11 to g13, but I know the engine construction is still the same (aluminum head, cast block, rubber hoses). VW specs their g13 to last “lifetime” so I change it every 3-4 years depending on maintenance and all. Nothing lasts lifetime in my opinion. The VW dealership sells g13 by the gallon and I think it was $50. Search online and you can get a gallon g13 concentrate a bit cheaper

@@OlisGarage Using Pentosin Pentofrost G11 is still okay, though, correct?

@@tchikosh it definitely is. The manual recommends replacing it every 2 years (manual was written for G11).

@@OlisGarage I used G13 for about 2 years and noticed some of the hoses had swollen and started to "sweat" a little despite not being very old, also i noticed sometimes when i turned on the heater it smelled a little bit like coolant ( it does have a tiny seep ) So i flushed it out and switched it to G11 and so far it's been perfect, i changed the hoses and they are still like new, and it doesn't smell like coolant anymore when i turn the heat on, it lasts less than G13, 2/3 years vs 5, but i'll definitely use G11 from now on. Some of the inhibitors in G13 and other modern OAT coolants seem to cause problems with the rubber hoses and gasket materials used in older engines, G11 also protects copper solder and brass better than the newer stuff.

Sounds like the fan isn’t coming on. I have a video diagnosing and replacing the thermoswitch. Check that one out. Don’t get a lower temp thermostat. It won’t fix your issue. If you’re overheating in traffic but not on highway, then I know your thermostat is opening. The airflow through the radiator just isn’t sufficient in traffic. That is fixed by a properly functioning thermoswitch

@@OlisGarage Wow, That was fast. Thank you! Yes, I changed the thermostat on the Radiator. that fixed the radiator not working properly. Now the temperature light flashes occasionally for like 30sec.-1 min. and stops again. Doesn't mater if I just started driving or if the temp is around 90.

@@felixweindorf4773 oh sweet, then you’re already a step ahead. Don’t pay attention to the light too much… what does the needle on the gauge say? Also if you let it idle for about 10 mins, does the fan come on and then turn off when the gauge is indicating around the middle?

Multiple people have told me that the light sometimes randomly blinks or blinks all the time. I’m not exactly sure how it’s supposed to work or how to fix it. That’s why I usually just pay attention to the needle in the gauge.

@@OlisGarage Yes, fan comes on and the gauge is right in the middle. That blinking light was my "overheating Problem". That realy helps. I was wondering about that blinking light. So I'm going to stick to the gauge. thank you! I would love to see more Mk1 videos. maybe about the shifting reparier kit. that's my next project;-) Your Chanel is by far the best content! thank you again!

Whichever method you use, you should make sure that in the end the system is 50% coolant and 50% distilled water. My method explains how I achieve that proper ratio after a flush without guesswork.

@@OlisGarage I used the Green antifreeze in previous fills, is that not recommended or does it not matter as long as i use the same glycol based concentrate after the flush?

@@juulin2567 don’t mix coolants is the rule of thumb. Some people say the green stuff isn’t for VWs. I honestly don’t know as I never buy the green stuff for my cars. I only use the green stuff in tractors.

@@OlisGarage Hey, was looking for a radiator for my 1989 cabriolet that fits?
