Help/advice Needed. Cooling System

[B14RY W]

Finally got my car back on the road on Friday with no issues until Saturday morning.

Since the car has been running again it has had issues with the cooling system. I have replaced the Radiator and Thermostad. After following instructions from some members on here I managed to get it to clear and the car ran perfectly on tick over for a few days and on Friday when going for its m.o.t, and then continued to run perfectly all Friday night on a blast to Falkirk, Dundee and then sunny Aberdeen before returning to Livingston.

Drove the car on Saturday morning and no hot air coming through the heaters and then started to over heat again. Took the car home and bled the system again and the car was fine until it got parked up for more than an hour. This pattern continued all day Saturday and all day Sunday and again today. Its finally got to much and its now parked up and I have my Golf back on the road.

My old boy reckons its the water pump and one of my mates reckons its Heater Matrix related. Can anyone shed any light on this or had a similar problem.

My car is a 97 Turbo 2000

Thanks in advance for any help.

Cheers

Not loosing any water mate.

Thermostat not opening? Simple job to remove and check

Take the cap off the reservoir and see if the return line from the turbo has water running through it when the engine is on. I fno tthen the water pump needs replaced.

could be the heater matrix, are your windows steaming up easily?

Brand new Thermostat mate. Checked before I fitted it.

Thanks for that mate.

Will give that a try tomorrow.

Any idea how difficult/easy a water pump is to change

Cheers

Blowers are working fine in the car and have hot air o plenty when the cooling system has been bled and working.

Blowers still work fine when over heating, but no hot air obviously.

Any thoughts?

Thanks

Are you sure your new thermostat is opening?

Checked it before I fitted it, and the car ran perfectly on Friday night. Popped it in a jug of boiling water before I fitted it.

I will remove it and check it again tomorrow though.

Thanks

Well what do you know, dodgy Thermostat.

Worked fine the first time I tested it. Removed it Yesterday to test again and it was sticking, and closing prematurely. Tested it again a while later and it was fine again. Took the car a run without the thermostat and all was good. The offending part has now been binned and a new one is on its way to me.

Needless to say I will be back to checking all parts three times before fitting again.

Thanks for all the help and suggestions

Nice when it turns out to be a cheap fix.

Could have been alot worse.

Bit of a pain though when a new part is faulty, really leaves you scratching your head.

Especially when I specifically tested it before fitting.
