LCR Owners - Important Regular Check

[storeyd]

My secondary water pump went off recently and I think its quite a common problem. I noticed that I could not hear it after I turned off the ignition.
For those who don't know, its an electric pump located near the radiator on the drivers side. The problem with mine was a loose connection that was solved by bending the connector to ensure good contact. When I did this the RPM of the pump was higher than ever before.

So always listen for the pump as its easy to hear. If you don't it could be of for months and lead to premature turbo damage.
It may even be worthwhile checking the connector by wiggling it when the pump is running.

would this apply to a basic 1.6 sx LEON 53 REG ?

 

[panholio]

Can't see it being of much use seeing as you don't have a turbo.

Thanks for reply. I thought so, just checking !!!!!!!!!!!!!!!

yes mate

think i better check mine, where should i be looking for this, i dont here all to much noise going after the car is off, all be it i normally leave a bit of cool down time after driving hard or long journey, maybe min.min and a half on idle on the drive before turning it off!

I've also noticed recently that my electric water pump has been silent, but only intermittantly. I've tried testing the feeds to the pump, but it seems to be always a very low voltage that's unchanging...
Could some one enlighten me as to whether this pump is ECU controlled?? I want to be sure that the supply is good to the pump before I go ahead with replacing it.

how much for a new one

 

[BCM]

does this look like a can of coke size silver bit! moved my wire about and its seems to make no diff, just wanna make sure this is the right thing!

 

[richybigman]

Good tip mate, i always listen out for mine.

 

[phatchoonz1]

how much for a new one

Been quoted just over 80 quid plus vat today for the pump itself. Hence why I want to make sure the one i've currently got is definitely getting the power it should do!

 

[m.r.davies]

thanks for the heads up

so long does the buzzing sound go on for ? i hear a short zzzzzzzz for about 1 second, is that it?

 

[richybigman]

I think about 10 minutes

 

[phatchoonz1]

This is the pump in my LCR incase anyone's wondering what it looks like...

and

 

[stpete]

the controler for this is I believe under the battery?

 

[phatchoonz1]

really? under the battery?
i've been hunting for a wiring diagram for the car, but not had a lot of joy really. Considering just taking the plunge and buying a new pump now, as it's probably going to end up being that, and i'm now getting a little concerned about it not working and the problems that will potentially cause...

I know there were differences with the VR6's in that some run everytime you turn the ignition off, and some would only run over a certain temp. Might be worth looking to make sure its not the case with the 1.8T too.

LCR pump will run regardless of engine temperature after switch-off.

Is this true for 1.8T's can't say have ever noticed the sound after switch off myself,but then again not been particularly looking out for it either.
