had a search around the forum but could not find the answer to this?can you help?
when i am driving slow or in heavy traffic temp gauge is running hot and the water temp according to a vdo gauge is about 130c now is this fine or not?
mk 2 16v 1990 spec. 144,000 just had all new belts fitted water pump is working.
heaters are fine fan is kicking in oil temp between 86-90.
-
there's no such thing as water that's 130?C :wink:
-
i know???......... :laugh:
vdo clock out of a audi 80 quat connected tothe temp sender on the side of the cylinder head?? :laugh:
-
isn't the temp on the side of the head for oil pressure or was that only with 8v engines?
your fan should come on before it gets to 100?C anyway. is the radiator scalding hot too?
-
yes mate! its a stange one this as the temp gauge rises with the vdo gauge
-
Coolant temp can reach over 100, thats why its not just water in the system, the coolant actually raises the boiling point.

"need cool runnings!"
you must be able to buy it for a few quid somewhere, you are talking about that film about the jamaican bobsleigh team with john candy right? :wink:
-
YES MATE A CLASSIC FILM...... :grin:

so does pressure, if you get the pressure high enough then 130c water is possible.
gas is gas due to the intermolecular forces and energy given to the system and energy opposing the system, conversely in a low enough partial vacumn you could reduce the boiling point of water aswell.
when i read this i was thinking of silent running with the sad ending, never seen cool running.

:shocked: :shocked: cant believe youve never seen cool runnings!! shame on you!!
are you sure your running the right temp sender?? it should be stamped on the ssender itself you need one that goes to 120degrees. if you have one for 100 degrees then it will make look as if your car is running hotter than it is!!
the reason i think this is the oil temp is normal!
-
she needs to watch cool runnings!!!!! :grin:
thx for the info!
-
i remember the trailer i looked like a good film, but i forgot to see it, will put it on my to watch list.
i had a thought was is you tickover at?. as mine sometime sticks at 1800 and overhaets as the fan cannot cool the engine sufficeintly at high tickovers, (i turn the interior heater on full and this keeeps it down).
just a thought

Wow thats some insight into Physics, I feel intellectually stimulated.
But indeed most car cooling systems do run at pressure enabling the coolant (Water or Anti freeze) to get hotter than boiling point.? your header tank pressure cap has a release pressure whereby if the pressure rises too much (eg say your head gasket blows) then the pressure can escape through the cap to stop your coolant hoses exploding. Did I say pressure enough?
Ive seen Cool Runnings.? But my Valver goes faster than any Bobsleigh, and I would hazard a guess its more comfortable even though ive never been in a bobsleigh.
But to try and answer your question, If your temp guage doesn't read too hot, your cooling fan cuts in and out correctly (should come on mainly at Idle), your interior heater is fine then I would say this is OK, although 130 degrees does sound a little high.? I would have expected around 110.
