Water Pump ?

[csj]

hello . car wet into garage hoping thermostat had gone , changed that but still no heat inside the car ,they are now saying that it could be the water pump . with my limited knowledge of cars doesn't the water pump spin with the timing belt , so how can it be bust . thanks for any help . john

The pump has a plastic impeller and is known to break. A lot of people change the pump during a cam belt change because it is difficult to get to.

[csj]

oh dear sounds expensive so where would the impeller go :-(

[chromedome]

Know idea where the impeller bits go but the pump is not that expensive, around

[csj]

thanks may as well ask em to change the belts as well .

If the impeller does fail it usually detaches from the shaft/spindle that is driven by the timing belt and would likely remain mostly intact in the cavity in the engine block that houses the water pump. Unless it's blasted itself to smithereens it shouldn't be able to go anywhere and cause any additional damage, apart from not doing it's job, which is serious in itself if it's not attended to PDQ!

well I hope it  is this as there sayiny it could be a head gasket . but still pretty expensive

[Russats]

Does it overheat on long journeys up hill??

[csj]

garage rang water pump goosed , gonna cost 400 with new timing belt pump thermo and coolant

[chromedome]

Check he's going to fit a timing belt kit. Includes new pulleys, etc.

 

Still sounds a bit expensive.

[csj]

got back today all done new pulleys etc heat in the car seemed to take a long time to heat up though , maybe working properly now

[chromedome]

Time to check the aux heater is working.

[csj]

[chromedome]

I'm not surprised. Do a search on the forum.

[csj]

I picked one up of the bay and amazingly it worked. Seems to be playing up a bit this year though. I would suggest checking if the aux water pump is working, as I recall when I replaced the brushes in mine it helped considerably with the heat in the car, previously I'd only start to get heat when the engine was at temperature. After replacing the brushes it got noticeably warmer quicker.

 

Actually, seeing as we're on the subject, noted today in the way into work cold air coming out of the front vents. At lunch-time I checked there was coolant in the header tank (there was) but on the way home once again no heat. However towards the end of my journey I realised the heater controls were unusually dark, no lighs on ac button either when on (not that I have working ac). So, looks like the panel is dead, current suspicion is something was dislodged when it was in the garage the other week (they adjusted the brakes under the dash somehow). The fans do come on though, am I barking up the wrong tree?

See other post, the disconnecting heater control unit brought it back to life.
