There dnt seem to be any airlook mate

 

Maybe you have air bubbles trapped in the cooling circuit. Maybe there is a post or video on YouTube that shows you the process with your exact engine.

 

Hi guys I'm new to this network I have problem with my astra j 1.6 the heaters are not warming up when the car is stationary if I drive the car the heat stay warm
I have changed the follow parts on the car
Water pump
Both temperature sensor
Full thermostat housing ad thermostat
I have flushed the system out with new coolent all the water pilpes are warming up on the car. The car dose not over heat I do have a smell come in car it smells like coolant but can't see a leak any help would be appreciated
Many thanks shabs

 

My name isn't orange?! Just realised. Got my membership pack last week too

 

pm mollygoogle or mixman matey they will be able to sort it for you :thumbs:

 

just thought of something else unsure if its been mentioned but is the heater flap motor working ok, the one that changes from windscreen to feet etc?

 

Yep, everything mechanical is fine. I did every check I could before I took it to the garage after looking at threads on here and I couldn't find anything. He said a software update might fix it (doubt it but the software does control the heating on this I think, it's got the CID) or that it could be the heater control panel. He said he won't know for sure until he's tech 2'd it.

 

Are the blowers working?

Are the blowers working?

Yeah, blowers are fine. Thermostat is fine, water pump is working, heater matrix is fine, there aren't any leaks and coolant level is fine.

It's currently working and it's not that cold anyway so I'll get over it :lol:

 

great, so you have heating now?

 

Well, I had! It's gone off again! I took it back and he's convinced it's not anything on the engine side and that it's definitely something electrical

 

nah, no warning, best way is to look at the expansion tank, the top pipe 2 pipes are water return pipes and should at most times be feeding water into the expansion tank, which shold be easy to see thanks to the coolant being red/orange.

 

Cheers, it's all working fine :thumbs:

 

this happened on mine when water pump stoped working. check also this.

 

How can I check if the water pump is working? Shouldn't I get some kind of light on or a warning on the CID?

 

Had a squeeze of the two pipes coming out the back of the engine, they weren't warm even though coolant temp was at 68degs.

After squeezing them the air coming from the blowers was noticeably warmer so I'm thinking I've got a blockage. Will do a coolant flush and hopefully that should sort it. Thanks for the help (Y)

 

I think the filter should be alright, I changed it about 8 months ago but the blow strength is fine

 

Is the thermostat near the coolant bottle?

I think the water pump must be ok as after I got to work my engine temp was at 85 degrees and it was a good 45 minute drive including some motorway.

 

if not check the pollen filter it maybe blocked :thumbs:

 

Put your hand on the hose after the thermostat, you should know if its opening if this gets hot.


The last time I had a problem like this is because the water pump failed so it wasn't pushing the hot water through the heater matrix. This also caused the engine temp to sky rocket.

 

Its getting to around 85 degrees give or take a few degrees according to the BC diag screen. How do I know if the term is opening?

cheers

 

what temp is the enigine getting too? it the thermostat opening?

 

I read that it could be an air lock in the coolant hoses, just ran the car up to 73 degrees with the coolant cap off, nothing seems to have changed. Is there another way to remove an air lock or have I done something wrong?
