VW T3 TDi Overheating FIXED! What was the problem? 

Thanks! Yeah we're finally at the point where we're planning a trip in it now! 😁👍

He will still watch it. You can bet your left cahoona on that.

Thanks very much!

Thanks! I had the pump timing dialled in perfectly when the spanner mishap happened. I was just tightening everything up! I did check it again after doing the head though. I believe the pipe clips are to do with them keeping even pressure on the hose, and that they don't work their way loose over time. I just find them annoying though.

Thanks! That's the plan! Fingers crossed.

Thank you! 😁

Thanks! Glad you like it. I thought it turned out well myself!

Thank you! I'm confident it was the thermostat. I didn't find issues with anything else as I went through it.

Thanks! 👍😁

I usually just put a small smear of rtv on the seal to help it cause I've had leaks before when I didn't. I just went overboard with it this time.

@@Endfloat I like to use a bit of silicon grease on o rings, I reckon it helps lubricate them so they settle into position properly.

I often do that actually. It depends on the application. It's rare I'd use RTV where there's an O-ring, but in this instance I did because I know how prone to leaking they are.

Thanks! I would have ran the engine without a stat until I got a new one if it had turned out that the one installed had gone bad and needed replacing. Luckily that wasn't the case. I didn't explain the thing about the golf well in the video. There's this thing where people with DSG VWs modify a setting that cuts the ignition at every gear change which means it pops through the exhaust on every gearshift. It sounds ridiculous, and is generally being driven by someone who looks like they replaced the driver's seat with a sun lounger.

@@Endfloat ahhh a pop corn limiter thing 🌽😂 they do sound dumb 😂

@@davidhenderson7722 ahh there's some knuckle draggers of "car enthusiasts" around my way. DSG farts are only one of a number of things they seemingly do just to impress their other knuckle dragging friends.

@@Endfloat lol.🤣

Glad I could help!

Is the insert that the plug goes into turning or is it the threads pulled? Either way, see if you can pry up a little while turning it to see if it comes free.

@@Endfloat yes it’s turning, thanks for the reply I’ll give it a go

Is the radiator getting hot?

Jump the fan switch connector and see if the fan is working on high and low speed. If the fan works its faulty wiring or a faulty fan switch.

They do work. They're just a pain to get on and off.

They eventually fail, as they loose their "springiness". They were used because of costs, not efficiency. With the average Vanagon being over 35 years old, they need to be replaced, before they allow leaks.

Yes, either that or the dirt wedged in the stat itself.

That's an old one my dad says! I always thought it was funny.

That's just what I said! 😁

I really do not understand it!

@@Endfloat Me neither, I could never understand the 'dump valve' craze from years ago but now it sounds like the Engine is going to explode @ 4000 rpm.. In 30 years time they will probably think to themselves 'what a dick I was'..

I surely will, thanks!
