Water Circulation Pump

[BRAD]

Can someone explain how it works? I have put a new glow plug in my aux heater as mine was smoking and not heating, this has fixed this and heats up ok. But now heater cuts out after about a minute or so. I have looked on vag-com and one of temp gauges goes up to 270 and faults overheating and the pump is saying off. If I go on a run the aux heater is working but it takes about 5 mile or so before car reaches working temperature.

The car has done 120,000 mile so assume from posts on forum that pump brushes are u s.

 

Is the aux heater working because water circulating through engine and therefore around aux heater keeping it cool?

 

Should you hear pump working when stopped with aux heater running?

 

And if the system is working properly how fast should car warm up just ticking over.

I know how a water pump works. This is a water circulation pump or run on pump that is fitted behind fuel filter against bulkhead on 19 tdi.You will find a few post about them in Faqs, Common Questions And Solutions

I stand corrected then...Was only trying to help.

[mumof4]

well..i have the correct link this time..but hesitant to post it as im prob wrong again....so wont..LOL.

Brad, This aint going to be a detailed story about how it works - read the faq's like the rest of us did.

 

The heater - just like a back boiler will 'kick in and out as rquired to heat the cooling water of the engine. Were it to stay on I rather suspect it would boil the water that passes through it rather tham warm it. If your car is warm after 5 miles it sounds like it's operating well.

 

When 'stone cold it will heat for longer periods than when it nearing its shut off temperature. It only operates below outside temperatures of 10 degrees, and we have had it fairly mild in the last week or two.

 

The pump to which you refer is an after run pump which continues to circulate a small amount of coolant water around for a couple of minutes or so after the engine has stopped.

 

EDIT: your Questions...

 

"stopped"... is that engine stopped or car stopped??? You would need darn good hearing to hear the pump over the roar of the 'boiler

 

You would feel heat after about five minutes if the car has not been driven. expect it to be warm as toast after fifteen minutes or so.

I have to concede Brad that I didn't know what circulates the water through the auxilliary heater, and have no experience with working on the pump :lol:

 

 

 

You say it cuts out after a minute or so - does remain cut out or does it fire up again after a short period?

Yes it does kick back in and stays on but it just seems to take a long time to heat up the car. I would have assumed the car would heat up a lot quicker than it does, having read the posts about putting a new pump on and the car being up to working temperature in 3 minute.

It just seems having replaced the glow plug and getting the heater working hasn

Brad - I'm on my fourth Galaxy. I have never got any up to full working temperature in less than 9~10 minutes - even with hard driving.

If you want instant heat..plug a hairdryer in..far as im aware, you aint gonna get instant heat in a few mins.Failing that..use a hot water bottle and wear thermals.Another suggestion...eat loadsa beans the night before and have yerself a nice warm gasseous interior.will keep yer rear warm aswell.

 

Unless..you on about the engine heating up....do what my dad used to do years ago....wrap it up warm with some nice cosey blankets.

 

 

 

You are asking the impossible of a galaxy!!..instant heat??..i know no one who has it.From cold an engine etc has to heat up...so it will take time to get hot air, besides, the aux dont kick in unless 10c or less.

Oho..hold on there..swearing is nay allowed on this forum, consider your post edited!!

 

We on this forum do our best to help those who need it, we have and are trying to help you and im glad that you have found some bits useful.

 

FYI..my aux hasnt worked in months but i still get hot air out of the vents and the car heats up just a bit slower than normal.No great loss.New glow plug is all that i need and i will get around to doing it one day.

 

Some peeps differ on this forum as to what causes what problem, and not all problems are solved immediately, some of the more knowledgeable members only come on every few weeks...seatkid knows his stuff and has been around a long time.As has wolfie and many others.Some like me havent been here that long and are still learning..it all takes time unless you have bottomless pockets and nip to Frauds.

 

Try useing the search again, you never knw what may come up..instead of searching just technical, search the whole forum.

 

Have a look at this site if you need to know how a part works and havent recieved the answer you require on here..

All I wanted in the first place was an explanation how the pumps works, as after replacing the glow plug (because aux heater not heating and blowing out clouds of smoke) hasn't seemed to make any difference to the car heating up.

I have only had the car for a month (bought it from the auction big mistake) and this site has been very helpful in sorting out a lot of problems that I have had will the car.

If it wasn't for my wife liking the car so much, I would be either selling or burning the piece of ****.

 

 

if folks can help they will - if you dont get any replies the chances are that folk dont know or aren't sure its recent that anybody has tied this pump to the slow warming up problem (I cant remember any other posts over the years)

How will the cooling system in your car work well if not for the water pump? It is one of the vital components in removing heat from your engine and keep your engine temperature in a manageable level.

The water pump is a centrifugal pump driven by a belt connected to the crankshaft of the engine. It circulates coolant form the radiator, through the engine, and back to the radiator. The water pump has a shaft with a pulley on one end and a pump rotor on the other end. When the pulley is spun by a belt, the rotor starts to circulate the coolant.

Car water pumps have an inlet near the center so the coolant returning from the radiator hits the pump vanes. The pump vanes fling the coolant to the outside of the water pump, where it enters the engine.

Auto water pumps have various designs for different purposes. Most include a rotating impeller, which transmits the coolant through the engine block. As for most rear-wheel drive cars, the fan is installed on the end of the water pump shaft. These car water pumps usually have a spring-loaded seal to prevent water leakage around the pump shaft. Some water pumps are fitted with pre-packed ball bearings sealed at each end so lubrication won't be necessary. It is a must to have a fully-functioning water pump to avoid overheating and engine wear and tear engine. The circulating capability of an auto water pump will certainly cool your engine down at a manageable temperature.

I am talking about run on pump to the auxheater not the water pump

[mumof4]

did you look at the download pdf file...im trying my hardest here ..i am searching the ruddy internet.

I am talking about run on pump to the auxheater not the water pump

 

so did you look at the pdf file the (link was posted for you) which is a water pump of THE RUN ON TYPE

 

btw I dont think its the run on pump to the auxheater

You know Brad, a thank you helps every now and then..even if the info posted is not what you were after, we search for you..we look for you and it gets thrown back at us.well, this little gal aint searching no more for you.Thanks cost nothing.

 

By the way..5 miles to warm the cabin sounds bloody good to me.

 

Hope you get the help you need from other members.

[Guest wolfie]

OOOH! STRESSY MARE AINT WE :D you not getting any? :angry2:

[mumof4]

you not getting any? :D

 

 

Now that be telling.. :angry2: :D :D

[Dave-G]

I don't think I can offer you any more Brad, Might be worth considering that the cabin space on a Galaxy is near twice as large as the average car so it takes a tad longer to convert all that cold air. I also run the rear heater on initial warm up if it's especially cold.

 

Perhaps if you ask the author of thread about changing brushes on the run on pump he might be able to take you further. Since you seem to feel so strongly that it may have something for you, instinct being such a powerfull thing - sometimes we just have to go with it.

 

Can I suggest you suck it and see, then let us know? It seems quite a small job. You'll need to be quick about it though otherwise it'll be too warm to evaluate the difference.
