Overheating

I think you are mistaken regarding power, the oil pump pumps regardless

Go and get a hand pump. Stick it in a barrel of water, and pump it for five minutes. Then do the same with a barrel of gearbox oil.

Then tell me that oil pumps "pump regardless".

...the oil it pumps is not cold it's allowed to get to working temperature as normal ...

Ian was right
I'm done.. foe list beckons

Ian was right on the mark...

I spoke to Ian 357 days ago (give or take a day) and was perplexed by his desire to jump ship. My puzzlement no longer consists of why, more of which ship he jumped to.......and is there any room left?

but I'm a belligerant bugger and I'll stay on board if only to pi$$ off the iceberg

My problem is resolved. New radiator fitted and she now sits just below the LED even in this really hot weather. Radiator was from GSF and looked to be really good quality with stainless fins rather than aluminium and was a real bargain (thanks to Club discount £117). My son tells me that you get what you pay for and buy cheap, buy twice ! He did agree though when he saw it that it did look well made, time will tell ! Think I will do a post mortem on the old one as it is very heavy. Should have replaced it in the first place having wasted a tenner on useless flushing products.
Oh, come on you boys, stop spitting your dummies out ! These comments on here are intended to help members and we all have different views on things, sometimes right and sometimes wrong. I fear folks will be afraid to say anything soon because they might be shot down in flames. If one or the other was broken down in a layby would the other just drive past ? No of course not, thats what it is all about. RANT OVER X

Sigh... once again, viscosity is relevant, base is not.

FFS ! Fake oil is no good in these engines....NO good! Mineral oil , min-er- al .....not synthetic .....

Sorry to arrive late at the party, but i have just come accross this thread and it made me wonder if my problem was actually my rad. I have been suspecting dash voltage regulator as i seem to be running hot, but also have an over reading fuel gauge. But having changed the regulator the gauges read exactly the same?! I hope you dont mind, but being an anti-typing kind of man, i have copied the text below from my post on the electrics forum as thought i was getting into mechanical terretory... the relevent bit i have highlighted

UPDATE
right i've now been out with a multi meter and unfortunately i have 11.8v on the innermost (to the centre of the vehicle) side, and 9.9v on the other leg, so my new voltage regulator is clearly working as it should. So either the engine is running hot and the fuel gauge is also over reading - too big a coincidence? Or some other electrical component is at fault, although i cannot think what that would be.

I was supposed to be going away on Thursday, but not sure its a good idea now if the van really is running at 2/3 up the gauge. I was much happier when i thought it was just over reading! On the overheating front it does come down to just on the high side of the light when i run the heater flat out and fan full on, but otherwise sits at 2/3 but all behaving normally:
after about 8 mins at tickover the stat opens and the rad starts to get warm after 12-15 minuts still sitting at tickover the rad is fully hot and the fan kicks in, runs for about 2 minutes then stops and doesnt kick in again for about another 4-5 minutes and then repeat...

All the above seems pretty correct to me, although i know little specifically about WBX engines, so im now officially confused! Thanks in advance for any help,
Si

Given that it's behaving normally when there's some air flowing, but not when the fan should be helping, it sounds like the rad's OK - but just to double check, it should be hot to the touch all over, top and bottom, side to side.

I've just replaced the fan switch on mine, because it wasn't working on low speed. It was on high, but that required the gauge to get to a similar level to you.

Take the lower grille off, and you'll see the plug for the fan switch on the side of the rad. Unplug it. One of the three terminals is a permanent live, the other two go to the fan (high via a relay). Find out, using the multimeter, which is +12v. Then bridge it to one of the two. Then to the other. One's much louder than the other. If you're only getting the loud one when the van's hot, that's your problem. Quick and easy to change the switch, without losing much coolant, so you (probably) won't need to bleed.

Ive just been onto my local VW van centre to get some antifreeze. They state that they only stock G13 spec as this superceeds G12 (obviously), will this be ok ?. And its 8.93 per 1.5L bottle!.
