No cockeral switch here either I changed it for a lower temp range

i think you mean you changed the thermostat? I dont have one at all!!! Scooby engines dont like being to warm, so I like the peace of mind that I can if I want throw the fan on!

No mate the switch.. off a rocco I think

The temp transmitter to the fan stopped working. All fixed, I guess that's why it wasn't so warm either

Glad you got it sorted Roger, but this bit (that I put in bold) is a bit confusing (well to me anyway )

Just as a matter of interest, what wasn't so warm ?

This is interesting. I discussed this before. Many folks say that, when the low coolant circuit kicks in the gauge does not move over to the right. I read somewhere that it does, apparently so you can clearly see the red led.

My 89 van does not do this gauge moving thing, I cannot remember if the 85 van does (it is STILL at the body shop - long story)

I wonder if there are 2 versions. I do know there are 2 versions of the circuit (that looks like a relay) number 43 and also can be numbered 42, so perhaps that is where this difference comes from ? Our "Angeloeves" (sp) seems to know about this...

If you bridge out the plug from the temp sender on the t/stat housing OR touch it to earth that will send the needle to max, the plug on the header tank just controls the level sensor LED and should need to be reset by switching the ignition off and back on again. The 'Overheat' LED control is through the mysterious relay 46 or what-ever it is called.

Yes I got that Ian, but it seems on some folks vans (like Roger's), that when the low coolant sensor kicks in it moves the needle to the right.

p.s. "relay" number = 43 or 42 on earlier vans

Could somebody translate.....cus I haven't got a clue....what did he do to fix the problem...something to do with flange receptive clips or was it double overhead underhangs...something technical anyway...

I understood that the radiator fan switch was buggered (no surprise there then !) but ....

Basically yes it was the fan switch. I think the confusion here from my early replies might be when the cable pop's off my header tank that sends the needle to the far right, nothing else.

I don't know why but the plug to the cable that links to my header tank doesn't seem to fit too well. Maybe it's none standard or something. But that's a separate issue than what I started with.

I would get that low coolant sensor sorted. Until then I would check the coolant level in the left hand header tank often. Reason = by the time these vans get to the age they are, coolant loss (from a variety of places) is always a possibility. In addition, if you do run low and get airlocks you can easily damage the motor

I check my low coolant sensor about once a month as I had a narrow escape (a few years ago - long story)

I do just that I had a nasty incontinent last year where my v-belt popped off and I couldn't stop anywhere at the time. By the time I stopped a pipe had burst, I decided to sort quite allot of my coolant system out then. I replaced the pipe of course and the header tank. Also I read on here about popping some milton in my expansion tank for a good clean out. Also I brought a new sensor for the header as the seal had more or less gone which was when I noticed the previous owner (or someone) had chipped a bit off the plastic. I thought nothing of it. I now realise this is so the cable stays on.. I might have a look for another plug. I don't want to modify it as per the last owner.

But since then i've not had an issue with my coolant.. Oh I also cleared out my whole coolant system into various vessels and then re-cycled it by filtering it though some old pants (clean pants).

Could I just ask you why when that happened you couldnt stop anywhere?

Bank Job?

I guess the answer is you can always stop.. But I was on the A34 and there was no hard shoulder, approaching a roundabout. So I basically thought I'd aimed to get to the other side of the roundabout where I knew there was a bus stop and I didn't make it in time.. Ah well..

And the swag was weighing me down..
