Why Would Some One Do This?

[big blue]

We have a 2000 MK1 Diesel Auto - with a heating problem.

Temp normally is very low (white section on the gauge) takes ages to move off the bottom stop but some times has gone into the red (once on holiday), no heat into the cabin and the pipes that go to the rear AUX heater never got warm.

 

Having read a lot of the heating/cooling posts on this site i decided it must be 1 of 5 things

1.. Airlock

2.. Thermostat

3.. Water pump

4.. Head gasket

5.. All of the the above.

 

I thought i got rid of the airlock about 4 weeks ago (removed the rubber from the AUX heater - loads of brown water then nice blue stuff - refilled - then next day did the same with the pipe that go into the front heater matrix), it worked for a week or so, then back to square one.

 

So number 2 on the list was the thermostat.

Got one off E-Bay and while i was at it got a water pump (just in case).

 

So this weekend i got to work................

 

After a couple of hours i found this..

 

 

 

At this point i decided i would replace the entire water pump - so several houre later i got this out....

 

 

 

so.. why would some one pull out the thermostat - rip it in bits and then glue the pump back together.

 

The car now runs at a contstant temp ( middle of the gauge) - we got a lot of steam / misting on the windows once the heater came on - i hope this is just water / moisture from the heater matrix housing (as its not been used for a long time so water could have got in there i hope) and not a hole in the heater matrix - but i am still getting a lot of pressure in the header tank.

 

Any thoughts......

Because they had absolutely no money at all and improvised to keep the car running?

dodgy dealer saving costs? or mate down the road?
