my engine has always run hot Done timing changed oil but always the same When I had the engine out I found a baby wipe in the fan ( not mine ) The only time it could have got their is on a test run (2014) before refitting tins and foam seal It was in there long ways round wish I had taken a photo Think it was covering about 20 to 30 percent of the fan So not doing a test drive until it's all fitted Hope that's the end of it running too hot
If you havent touched it really since 2014, I would also go round looking hard for air leaks between the carburettor and cylinder head.. rubber boots, gaskets, unused brake booster hose takeoffs, vacuum feed for hot air flaps, or dirt in the carburettor blocking jets.
Sorry it just seamed hot compared to other vans I have had When on a longer drive and you stop for petrol it smelt hot But could not find anything wrong but I can tell you I have a clean fan now
They always smell hot after a run. Can’t really judge unless you’re measuring something like oil temp.
I managed to fold a piece of gauze wire to cover the fan "hole" to prevent debris from entering. Photo looking down from above.
I can remember my bus when I first had it got to the top of Birdlip Hill out of the Severn Valley towards Cirencester and there was a slight haze coming from the air vents.. Turns out it was running hot and dripping oil onto the heat exchangers and exhaust. but hot was just the way that engine was. Then the j cloth sticks to that and the whole lot gets sucked in ?
I was thinking I was unlucky getting baby wipe in fan I remember being on that test drive and see it floating in the air ( only rear tin on and no foam seal as only a test round the block ) Did not think it had been sucked in Is this more common than I thought ?
I think it's incredibly uncommon, I wouldn't make any effort to avoid it past not leaving such things in the engine bay...which you didn't.
Thank you kind sir! After fitting it, I found a commercially available version which does the same job. I'd twice had disintegrating engine foam enter the housing, but have had 50k trouble-free since fitting the gauze.
No, it's a type-4 fan guard. If you needed one I think VW would have fitted one. On a type 4 it's too easy to drop something into the van.
I've a JK plastic one fitted, but they aren't very robust and deteriorate over time, after a couple of years, you wipe it over and put your finger straight through. Tried to make one with a cheap sieve, but it didn't work...so I too am curious about the metal grill.

My DIY gauze is much more robust than a "cheap sieve", hard work to bend with fingers It hasn't decayed over many years
Understand the picture now...nice work...may have to persevere with the sieve idea as I doubt the one for a 1600 will fit
Whatever you do, don't use anything as fine as a sieve or you'll reduce the air flow too much. I'd suggest any guard on there will have some effect on that though maybe not much. People fit vortex rings to try and improve that air flow, I wouldn't want to add anything to interrupt that. Just gut feeling.
Looking at replacing the degrading centre of the guard with mesh from an old fan, utilizing the existing guard surround which is slightly thicker plastic...the mesh is about the same as existing . Totally get your point and it's a logical conclusion.....you a Vulcan?
