The thin oil cooler nut can be a challenge to get a good grip on. I sand off the taper on a cheap socket to get full grip on the oil cooler nut. Merry Christmas! Thanks again for the MK2 content & TDI content!
@@RestoDesignsnando But be sure to replace the fan switch in the coldest and windiest of the days so when you remove it all the coolant blows in your face and drips in the jacket sleeve
Hi Resto, thanks for the great video. I have a question. I own a MK3 VW Golf with a 1.9 TDI 90hp 1Z engine. During long drives, especially in high altitudes, I've noticed that my oil temperatures rise up to 120-130°C. I typically push the car to around 140 km/h. I've already replaced the water pump, radiator, added new coolant, and installed a new fan switch. I've even put in a thermostat that opens at 85 degrees Celsius, which helped a bit, but the temperature still climbs up to 130°C on extended drives. Do you have any suggestions? Should I consider fitting an oil cooler from an AFN engine since I heard they are bigger? What could be the cause of this problem?
Hi there, 130ºc is high for normal driving, it could be a few things, but first how high altitude are we talking about and what's the outside temps? 1: It could be your oil cooler is partly blocked so not working 100%, yes the AFN 110 oil cooler is slightly bigger but I've heard that the bolt is also slightly longer also. 2: It could be the make and grade of oil you are using? 3: The turbo which is oil cooled, your EGT's could be high due to a blocked exhaust system? or a boost leak and so the turbo is over working to hit it's boost. 4: Again your EGT's are high due to a remap and too much fuel (black smoke) or you have a faulty maf or coolant temp sensor making it over fuel.
The average altitude of Bulgaria is 470 m. I have tried different brands of 5w40 505-spec oil, but there's been no difference. I don't have a DPF filter and EGR, and I'm running a stock software with 90hp, producing almost zero black smoke. The pump timing is in the sweet spot, and the car runs very well with high responsiveness, so I don't believe the issue lies with the MAF. However, I will check how to diagnose the MAF and coolant sensors to ensure they are working properly. Congratulations on the website; I really like the workshop papers section.@@RestoDesignsnando
@@ChefKolyo Thank you 👍🏼, maybe it's just the oil cooler then, if it hasn't been replace, then it is almost 25+ years old. Here in Portugal we use 10w40 due to the temps, see here 👉🏼 oilincar.com/volkswagen/golf/3-1991-1998.php

That's a great tip! Thanks for sharing, it's been a joy bring you guys some mk2 content, hopefully I'll be able to keep it coming.
The fan switch is a 30mm, good video.
Thanks for that, I never did workout the size 👍🏼

Thanks, same to you 🙏🏼
Motor 1.9 AFN?
Yes from the Golf mk3 110
Pal, I’ve ordered 2 parts from you..nothing
Hi there, yes they have been sent, I'll update the tracking number on your order.
Yep all undated, sorry about that, Thank you for your order 👍🏼
I've emailed you this morning, please check your spam. thx
