Water Temp!!!!!

[checkpoint-direct.co.uk]

Just fitted my new gauge today and wish i never had!  On the way home the car went up to 130c!  and didnt move!  and the worst thing is i think that is the limit of the gauge!  Please tell me this cannot be the case as the car runs perfectly!  Surely the car would self destruct at those temps!  worst thing is turn on the air con to get the fans on and the needle still disnt move.

Any ideas?

faulty gge or sender..where have u plumbed it in and which gge are u using

[checkpoint-direct.co.uk]

its a cheap autogague plumbed in onto the pipe off the radiator using a thingy with a threaded thing in it to allow the sender to be installed.  my worrying thing is it did start at 40 when i started her up but next time i looked it was way up and it did show a few degrees less after i left it for a while?  surely the stock temp gague would show off before it sees 130c!

Is it plumbed into the top or the bottom of the radiator ? Maybe your measuring the temp before its cooled down by the radiator ?? If its that hot i would have thought it would show hot on the naff standard gauge.

standard gge only moves just before u blow up..my guess is deff faulty gge or sender

Teach you to buy cheap aftermarket stuff......................take it off and bin it bro....I\'ve been using VDO for years (old school I know) and it is a not too expensive product but good quality...:Typing

Have you got a Power FC ? If so and you have the commander it can be shown on there.

Sounds like a cheap gauge or sender really. 130 degrees is boiling coolant! You\'d have noticed something wrong if it really was at 130: Like tons of steam coming out the bonnet.

Also, if it had really hit 130, the standard temp gauge actually starts to move off halfway at this point, so it\'d shown hot too.

Might not boil at that point - depends on how much coolant is in there - a strong mix plus the operating temperature may see very high temps before boiling.

I agree though - the stock sensor would move before then - just!

I would have thought the cooling fans should have come on if it\'s really that hot! do they? what year is it? if it\'s a 93 the Thermoswitch is rated at 108c, it is seperate from the (standard) ecu and feeds fan relay no 3 direct.
so sounds like the guage to me,
good luck Bob

thanks guys.  i will swap it over and hope that makes a difference!

Your standard rubbish gauge would move at 120oC so if that is still in the middle when showing 130oC then your new gauge is deffo way off.

130oC is bye bye seal time.

Well, ok. Technically, 130 degrees is the boiling point of water at the pressure it runs in the coolant system. but once you\'ve added anti-freeze, it changes.....but i\'m not sure if the boiling point goes up or down to be honest.

[ro284]

as i understand it the more coolant you add, the lower the boiling point will be

if your gauage has one wire going to it, you may need to earth the block that the sender screws into other wise the outside of the sender doesnt get well earthed.    Just hold a wire on it and attach the other end to the batterie negative and se what happens.
