Feeling Hot Hot Hot

[mycerbera]

Can't belive it!
Got stuck in traffic last night in pooring rain and Cerby decided to start smoking! Pooring smoke out from the passenger side of the bonnet. Pulled over and let it cool for 20mins, called Steve at Rachtech for advice, filled header tank up to the brim, (a whole watering can full!) blead air out using wing nuts on brass taps, then cap on and off I went home.
Anyone else had over heating props?
Whats the cause of this?
Any precautions and mods to stop it happening again?
I'm now carrying 2 bottles of water with me in the boot, just in case!
(Also found that washer pipe had melted itself on the hot manifold)

Are you sure the fans are coming on ?

Let it heat up and check that they or it (I only have one fan) are running.

Surely the smoke/steam could have just been the washer tubing. That has also happened to me !

Mine overheated when the bleed valve on the radiator sprung a slight leak (a fine stream of water 'p1ss1ng' out and soaking the spring with coolant, nice!) - once the coolant had reached a certain level, the temp gauge started creeping up, then back down to 85 when the fans kicked in. Eventually there was not enough coolant to cool the engine. Fixed with a couple of layers of PTFE tape and some posh water (it holds 5 litres!!).
The steam you mentioned probably found it's way out of the blue pressure valve on top of the header tank, though you should check all the hoses, otter switch, fans, water pump etc..

It also overheated when I test drove it, but that's because the belt 'fell off'!!

The waterpump isn't driven by a belt - it's straight off the same jackshaft that the PAS and Oil pump use - so that was clearly a lie.

Mycerbera - apparently you're not supposed to use those brass bleed nuts at all - the system is self bleeding (at that point) from those two little pipes coming off the back. Check with your dealer?

Mycerb - you havent had any luck have you. Hope it is nowt serious, that the car is now sorted and that you can start enjoying it. Fingers crossed.

Had overheating problems with mine; first time was leaky rad (look at tray underneath rad to see if there is water in it), second time was connections to fans which were not coming on. good luck!!

Mycerbera, i have to say it sounds that you have been extremely unlucky to have all the problems you've had. Has it been worth all the trouble? I do hope you manage to get all the trouble ironed out!
