Hi all, My van drives like a dream but of late the temp light comes on when starting (as it should ) but instead of settleing down to just before half way the needle go's to the far right (as if over heating) After about a mile or two it settles down to half way.

this is new to the van as it's always done the quick red light flash (as it should) and settled down after about 5 - 10 seconds.

I drove over 300 mile last weekend with no problems (after the temp gauge and Red light had settled, 1-2 mile)

Sorry to sound long winded. Any help would be great as im a bit crap on the tools. Sherlock

A quick update ive just been out in the van and the light seems to come on for even longer periods before settling down. And for no reason shoots up into the red again for 5 mins or so before going down again.

What the blithering heck is going on ????

any help would be great.

check coolant level or sensor in expansion bottle.
thats what it does when the coolant level drops......

its either a airlock, or a electrical fault.....
does the heater go cold about 3 mins after the gauge shoots? or before?
well 17litres after?

check the coolant level is correct..... the light works from both the coolant level and the temp......

are you loosing coolant?

also make sure the connectors on the senders are not furred up.causing a bad connection.give them a rub with emery cloth...

Thanks to all. no im not loosing any coolant.
Mocki... not sure if the heater goes cold 3 mins after gauge shoots to the hot (will check out in the morn)
Coolent level is still up ( in the top up pot)

Sukhoi27...where are the connectors on the sender (in fact where is the sender) if I can find them I will give them a clean up.

very greatfull to you both for your help. Thats what makes this a fantastic site. Cheers again. Sherlock

P.S in the words of david Soul...dont give up on us baby.

Top of the expansion tank. can't miss it. Black thing in the recess in the top of the tank.

Mine has developed the exact same symptoms over the last week

Tonight I started her up, and ran her with the coolant tank cap removed. After about 15 minutes she was warmed up and there was such a glug which I presume was an airlock, the coolant level dropped and so I topped it up.
I put the cap back on and ran it around for another 20 mins or so and all seems well

It may help you

Smiler, Sound to good to be try, but I will give that a go first thing in the am. Cheers

Fox. cheers mate I will check that out as well. Local man I see. Hi

Ah. Local, I am. to the point I have seen you a few times out and about

Hiya,

I had the exact same symptoms in a van last year...

Turned out to be an airlock caused by a faulty pressure cap on the resevoir.

I'd bleed it, it would be ok for a short time then recurred until I replaced the pressure cap.

After that, all sorted.

Silly answer I know but worth a check... The waters not freezing is it? Would give you those symptoms exactly from what I can work out. Check antifreeze levels to be sure.

Most of you guys said check the water level. And my reply was checked it out and all is good. But all I did was check out the top up tank and not the main water tank. I always thought that if you keep the top up tank topped up thats all you need to do. I opened the engine hatch to find that the main water tank was only half full(however the top up tank was looking full) so I topped up the main tank and all was sorted within seconds. Is that right ????? or should the top up tank keep the main tank full at all times ???

Sherlock

No mate - you have done the right thing now. Lets hope thats sorted it.

However, if it happens again soon - follow everyones advice and bleed the system....

Good luck!
