Evening all,

right then, after many years of fantastic service, all of a sudden my baby starts letting me down :(

Latest saga was car threw another coilpack, but never fear - thanks to Fezboy I had a spare!!

So my mate (who is an absolute gem, ta Steve:thumbup:) says, bring it round, he'll check if it is actually the coilpack and look it over.

So, after 10 mins, car all done, tea duly drunk then off to get snotnose and bogeyface from school.

Driving to get snotnose and I notice temp gauge nearly off the clock and then the pinging sound and red temp gauge!

Stop, ring my personal recovery service aka Steve, organise getting kids picked up and Steve follows me home (ta to nice Volvo driver who towed me off the roundabout), stopping twice to let the lump cool down.

Steve, after fiddling, draining and flushing the car on my drive, suggests it could be the thermostat. So he kindly replaces that when I've got the bits a couple of days later, but on idle the car does get warm - the gauge sits at 90 normally (I went through a stage thinking it was faulty as it stayed in exactly the same place whatever I did to the car!) but now it gets up to just shy of the red before the smaller fan kicks in.

Anyway, I'm not over confident that we have nailed the problem - I'm thinking serious stuff now, water pump?

Thoughts and suggestions please guys/girls?

Cheers

sounds like the water pump to me..........

I agree -watepump. Time for a cambelt change and a new water pump.

I would guess it's the water pump too. Next time the guage heads past 90 towards the red, turn the heater to max and the fan on max.

It should be blazing hot.

If not then it's almost certainly the pump.

If it is and the temperature starts to drop then look elsewhere (the heater matrix is nothing more than a fan cooled radiator).

Surely a fan should kick in before then?

I'd have hoped the cooling fan should kick in just about normal operating temperature so that if you're sat in traffic it will move air and keep the temp down.

Worth checking out why the fan comes on so late before putting a new cambelt and water pump in, but obviously don't be driving it around until you're sure it's good.

How many miles etc has it done on the current waterpump?

Another vote for the water pump. My first Octavia RS did similar (thankfully under warranty). The garage said that the thermostat jammed, resulting in the waterpump to burn out. The plastic impellor on the water pump is known for being prone to disintegrating, and should be replaced at the scheduled serice interval.

I got a metal impellor water pump fitted when I got the cambelt changed on my current RS.

I would think that if the pump isn't moving the water effectively the radiator fan switch would take longer to get to a temperature that would trigger the fan to kick in.

my tdi did something similar the other day. Tootling round Huddersfield after dropping SWMBO off at uni the temp guage went upto around the 100degree mark, it did rise a little more but then went back down to 100degree's. It hasn't done it since and no errors show up within VagCom. The car has done 109,000 miles on the original waterpump and it had the Temp Sensor changed about 20,000 miles ago due to the temp guage dropping and rising erracticaly.

I have a feeling it is the waterpump but am going to keep and eye on it for the next few weeks and if it doesn't happen again then it's happy days.

I have to admit that I would be more nervous if my temp guage went into the red. Hope you get it sorted soon.

As said the fan wont kick it. With the water pump not working you have very little circulation so the hot water doesnt get to the switch to turn them on.

Best bet is pop the return off the header tank, give it a rev up, you should have a good steady stream of coolant coming out, if you dont, water pump has fallen apart.

I'd get that sorted sooner rather than later mate. Sods law means it'll probably pack in at 3am in the rain on a road in the middle of nowhere, when you left your mobile at home!

Got my belt/pump done at the Skoda dealer in Huddersfield for £270...

I'm booked in for a service next month, I'm thinking about bringing the 120k service forward 10k and doing it next month.
