not if the airlock is where your sender is , generally speaking if there is no water around the sender they will read normal temperature as they require water to create the contact !
also the engine (petrol)will usually ping (as in pre ignite)if it gets too hot
i know this from experience as the brumby did it on the way home one night but the temp guage read normal!
Clarkie, I just had a look at pick-a-part and picked up a volvo one as in the bottom pic, the pressure cap is only 75 kpa about 10 lb, I grabbed one of a SAAB, that was 110 KPa, that's just under 16 lb, I know your the Volvo guru, so do they come in 15 lb also? Going to fabricate a bracket and if it works it's only cost me $13 instead of the $120 odd for LR.Quote:

I didn't want to spend $120 on a LR tank so took some forum advise and wentr to the wreckers and picked up this $13 Volvo tank.
I also scored a SAAB pressure cap.
With a little modification to the bracket here's the end result.

I remember an article from approx 6 years ago where we found that there were four different types of expansion tank available as spares.
The best one was the 'natural' semi-transparent plastic type.
Original Black plastic was rubbish.
Opaque white was rubbish.
Can't remember the third.
Best was given above.
Get an O2 check done on your system to confirm a leaking head gasket. I think it's a fool proof method when deliberating the subject.
Fitting a new cap is also a good way to ensure built up presure can reliably escape.
15lb caps on Ovlov's, not to my knowledge.....
Now that ive seen your mod i'm going to do exactly the same in the county.....
That is neat and being part of the Ford Stable, it suits...:D:D:D
And they're cheap and compact enough to carry as a spare. Since they have the same diameter hose outlets as LR, one could carry a spare and use an occy srap or 2 in an emergency to get one out of trouble. They should last, they seem to out last all those Volvos produced.Quote:

the header tank failed on the defer last night it was an old black one. bottom hose looked a bit tatty so i got one of those too 400 bucks later:mad: im on the road again what a real peice of crap these tanks are
Maybe someone who has changed them could do a 'pour test'.Quote:

Best to know this before we all take off to the nearest "Dismantlers".:D
The LR one in my Disc. looks a bit bigger especially on the firewall end, but it's hard to tell by looking at them due to the odd shape.
The Landrover one is a bit bigger.
I took it for a run today in 30 deg heat with the aircon going, Parked for 20 mins with the engine running and aircond going ( did the soccer mom thing picked up kid from school.) and it appeared to be ok.
Is size really important, would have thought if there is room for expansion and a reserve of water then It would be ok. Interesting whilst in the wreckers that most vehicles including V8s only had small expansion tanks. Would be interested in what size Toyos, Patrols etc have in tank size.
I haven't actually compared the volume of volume of liquid in the Landrover one up to its '+' inside the tank to the Max on the Volvo one.
