right - need urgent help before i torchh the golf - or blow the engine
following my recovery, and finding out that my stat and matrix had gone i have replaced them
but i still have an issue
when i fisrt start the engine, the water light goes out.
then after a while it starts flashing.
the level is ok.
the AA man says theres another sensor that can cuase this light to flash
HELP.
-
Level sensor which is part of the expansion tank playing up?
-
no, removed, bridged etc, still the same :cry:
-
further to my last,
I tunred the ignition to 2
all lights flash then the water one goes out.
stays out for about 30 seconds ( same as when engine is running ) then starts flashing again
so this fault is the same with or without engine running :cry:
are the 3 sensors on the end of the block
i have red / yellow, blue / white and green/ red wires going to 3 sensors, all round the big plastic flange.
help please, I dont fancy blowing me engine up :shocked:
-
I think its the red/yellow sensor thats your dash temp gauge. Swap that wire round onto the other sensors to see if the fault clears up?? Perhaps the overheating baked the sensor?
-
cheers dave, fooking thing, thank fook i got a spare lump to nick sensors off :undecided:
-
is it a pre-90, if so the light is controleld by the coolant light control relay, #53 clipped above the fusebox. pop it out and see if that sorts it!
-
erm, wouldnt know, its got the hazard light switch on the steering column. :undecided:
-
90spec then, gonna be down to the sensor, wire or the clocks! as conker says chuck the red/yel wire to one o the other 2 sensors :)
-
cheers both,
job for tomorrow then ,
then i can use one fromthe spare donk,
then finally bleed the system properly,
check the stat and matrix for leaks,
rebuild the interior,
fit the pas pump back on,
and then get sponsorship from savlon, i am cut to shreds :grin:

you have finally passed the initiation! good old heater matrix replacement! :grin:
-
conker had same problem,
changed coolant tank and tried all configurations of the senders and readings didnt change..light still flashing!
Funny thing is, it suddenly stopped flashing in the good summer weeks and started flashing again recently!
Ive left it to the clocks..... :lipsrsealed:
Good luck :smiley:
-
Mine was faulty expansion tank wiring. Bought one from ECP and all sorted.
-
right then, up at 6am :shocked: and started afresh.
changed all 3 sensor wires rounds. STILL the same :cry: engine running ( neighbours will no doubt be round complaining again ) or just ignition on
went out of the garage and chose one of the 2 corsas to kick - daughters was nearest - kicked satis :smiley:
went back in and put everything back to how it was.
started back at the begining. water level good ( still trying to bleed and leak check )
Bridged the expansion tank wire again - PROBLEM VANISHED :undecided: :angry: so I am hoping that I have cured summat by doing nothing or just moved the fault in the short term. Annoying thing is, the tank is only 5 months old :cry:
so it looks like its a trip out this avo for a new expansion tank , redo the bleed and leak check, then complete rebuilding it all so i can take it off the road in 5 weeks .
CHRIS - to be honest, the cuts arent really from doing the matrix, just the hissy fits or the thing not working and me ripping my hands out of tight spots :laugh: :embarassed:

Not 100% sure its that Dave. but the only way to tell is to change it, then get the car run up to temp, bled etc.
Then i will see. spooky how the Stat, the Matrix and the expansion tank all go pete tong together, unless the stat failing took out the tank and the matrix :undecided: :cry:
-
could be dodgy wiring to the header tank, have a good look at it!
-

but but jumping the connector ( which is clean etc ) it cures the fault - wires look ok and i wiggled them and the fault stayed gone.
could the fact the stat was stuck closed cause the float to go tits up ?????
-
yeah, but you said you tried this before and it didnt fix it, hence slightly dodgy wiring ;)
-
new tank time then to be sure, :cry: just popped home and wiring is spot on .
oh well, more expense, etc etc :lipsrsealed:
-
Its only a tenner and you get a nice new shiny one, although I guess yours was new anyway.
-
yeah thanks for that dave :laugh:
-
all sorted, full report in dub rides coming soon :wink:
