T25 1983 over heating :(

[Zoe]

Well that would be £100 cheaper than the bloody garage quoted just for the pump!!

[Ian Hulley]

Did they try to bleed any air out of the system at all ?

[Mocki]

ok, its overheating very fast....almost deffo the waterpump....unless its got a airlock..... is the water going round in the header tank?
if you cant do it, get in touch with fullsunian
hes at grantham, but should be able to help you.



DONT drive it . you will cook the engine.........

its a pity there isnt anyone nearer, like say calverton who could do it these days

[Ian Hulley]

Ensure that your cooling hoses resemble this ...

Easiest to see is the pair of large hoses crossing the rear of the engine bay.

Update

Picked the van up from the garage new thermostat in. Drove it 11 miles to a different garage that know a little more about Vw!
Driving there the needle moved between the light and right up high with a needle with to max!
The light came on only once! The fan didn't seem to kick in and the heater blew hot and got red hot when the needle went all the way up and light flashed!!

water pump not working
the belt is turning the pump pulley is it?

Which part of

DONT drive it . you will cook the engine.........

do you not understand ! You may have done irrepairable damage !

[ghost123uk]

the heater is blowIng red hot!

If this is the case then it ain't the water pump.

Thermostat has been changed so (as long as they did it right) it ain't that.

I wonder what makes them think no water is getting to the rad ?

DON'T DRIVE IT ( unless you wish to fork out £1000 for a new engine )

You need to get someone who knows these vans to look at it.
Ask around on here for a person or trusted garage near you.

Hi all, i'm not an expert, i'm just explaining my experience.

My 1.6TD bus went through a phase of over heating, the cab heaters were hot, the temp gauge was flashing, the radiator had bled fine after my new water pump was fitted, the old one I could turn by hand.

We found that the radiator was only half hot, yet it bled fine with a nice flow of water coming from the bleed bit. Also we found the additional water pump didn't work, not sure if na diesels or petrols have this. So both of these were changed, it's now as good as gold.

Hope this helps someone.

Another up date!

Halfords fitted a duff thermostat!
It's not the water pump!
Needs new fan switch as fan is not switching on and rad cap!
Should get it back tomorrow so bus type show here we cone:) fingers crossed for me:)

[Ian Hulley]

You don't have a 'Rad Cap'

[Zoe]

Radiator cap,

it ran fine this weekend even got cool air frOm my internal fans:)

And it was great to meet a whole bunch if the 80-90 lot at bus type had a fab time:)

[kevtherev]

no no
you don't have a radiator cap
it's sealed and has no cap

[Zoe]

sorry no comment been a busy bee

it was the coolant bottle camp which was replaced and still the seal is not good need a new bottle, is that an easy job?
there was an air lock in the system which my fab RAC man sorted for me, the valve in the diagram above at 41 was knacked so he took that out and put a fix in, cant ge them valves anymore! Brickwerks said its not important and to leave his quick fix
Its running like a dream now

Just need to replace the coolant bottle so any hints woul dbe good:)

Thanks
Zoe

I'm really sorry but you're making no sense.

Swapping the header tank is easy, Brickwerks sell them, park it with it's backend up in the air to minimise coolant loss. Check the wiki for details.
