Mk2 Golf OVERHEATING - Simple fix?

[@only-vans]

I think any VW, including our T3's used exactly the same radiator thermostatic switch in that era and suffered the exact same problem. Easy fix for those who didn't know about it ....now they do. Good Video Endfloat. P.S. here I am, yet again in my covid 2021 solitude, sat once again watching old machinery being fixed by a ... .....!

[@Endfloat]

Many thanks! Funnily enough, it's through t3s that I knew of this weak point, so it was the first place I looked after the level and the fuse.

Thanks! Say hi to everyone in Serbia for me! 😉

Another great video great to see you keeping another Mk 2 going on the road

[@Endfloat]

Thanks Gerard. I do love driving this. It's actually my wife's car! I do the maintenance on it and I can drive it whenever I want so it's a good arrangement! The automatics are rare these days.

Hey Pal, just came across your channel, great video. In the act of learning why does bridging the contacts start up the fans?

[@Endfloat]

The contacts are just on either side of a switch essentially, so by bridging them you're closing the connections that the switch would have been closing.

Nice simply fix expertly explained!!

[@Endfloat]

Many thanks Mick! Please do spread the good word! 😉

[@Krith220]

Nicely explained, just a question, can you also check the switch with two flat screwdrivers if you don't have those plyers around?

[@Endfloat]

Yeah of course. It's just a matter of bridging the contacts.

@@Endfloat checked it and the fan turned on so i need a new switch... thanks alot for the video!

Nice simple fix and informative video.

My Golf mk2 1.3cl starts when cold but then overheats and won't start when hot. I noticed the fan was running today but then stopped, I'm gonna try and bridge the fan switch like you did to see if I have the 2 speeds working. Still strange why it won't start when warm though.

[@martinweizenacker7129]

Regarding it won't start when hot, check the blue temperature sensor with a multimeter for it's resistance. It sits right on top of the thermostat housing, near the ignition distributor (1.3 engine only). Just unplug it, you don't need to remove the sensor for this. When the engine is at operating temperature, the resistance should be around 200-300 Ω. If it is much higher than that (common failure) it makes the fuel air mixture too rich and thus it won't start.

Tell me this, I drove my mk2 Golf Gti 8v not knowing there was too much oil in it, 2 inches above the dipstick too much 🤦🏻‍♂️ car didn’t get too far before stalling, I emptied out the oil and topped it up to proper level, it started but sounded nasty, so I turned it off, waited 10 minutes car won’t start now, just winds. Someone recommended I take plugs out, try starting it again to clear it if any oil, clean plugs put back in and it should start? What’s your opinion mate?

[@Endfloat]

The idea of spinning it over without the plugs in will clear the cylinders if oil got pushed past the rings. Your plugs would be fouled up as well if that happened which might be why its not starting, so clean them. Worst case, you may have blown seals or even bent a rod. Hopefully you got away with it though. Let me know the outcome.

[@liamblack8581]

@@Endfloat Will do, thanks for your advice! Gonna try that tomorrow.

[@anthonym2306]

Great help. Cheers mate

Careful replacing rad fan switch guys. It’s a plastic rad housing. Very easy to cross thread, then you need to buy a new rad. Don’t force anything

[@Endfloat]

Funny, mine is into a brass threaded insert if I remember correctly. Some might be different. Thanks for the heads up.
