how do u bleed or flush your coolings system b/c i have air in my system that is keeping my heater to not work

 

you have to park your car on a STEEP (like, 45*) hill, pop the radiator cap off, and let it work.


or do like I did, and get one of these:

a good place to find steep hills is at industrial buildings with truck loading docks. find one that doesn't operate on the weekends, and go park your car there during the day on the hill and let it cool down (i guess have a friend with you that can take you somewhere else so you don't hve to sit there for a few hours bored out of your mind) and then do what he said. make sure your climate control is set to heat.

 

open the radiator cap and turn ur heater all way to HOT and start ur car wen ur car will start to warm up u wil see bubbles coming outta ur radiator cap and finnally the coolant will start to come out and u have no air in ur system den....its not really the recomended way to do but ya u can try it....wat engine u have, vg or VE? ( please be specific for the engine nex time as i have no idea wut u r driving neither it says in ur profile)

edit: oh and for the flush u jus dont wanna drain the coolant from radiator and put the new one...thats not called flushing...u will need the machine to flush which will flush the coolant through the engine and radiator and that machine is pretty expensive. You better off going to the shop and have them flush for u plus they will bleed the air too and u might wanna put new thermostat too to be on the safe side cuz u wont need to worry about ur cooling system for atleast 3 years then....but if u only wanna bleed the air do wat i said.....

 

what me and Ben said was more than enough. doesn't matter which engine. and you forgot the part about having the car at a madcrazy incline. not all cars need that sort of incline but ours do.

 

I'm not sure what "machine" is required up there, but here in the US a garden hose is readily accessible. If you don't have one and can't borrow a neighbors you can pick one up for $10.

 

ya, i was trying to point the guy to the right direction instead of looking for a truck docking yard and i think he wanted to flush too and thats really not possible at dock yard LOL o ya and u r right about incline thingy. BUT it does matter for the different engines cuz there is a different bleeding procedure for every engine i mean principal is the same but way is different o well lets jus not create our own debate here but try to help the guy out lol

 

i just want to bled my cooling system how is that done

 

it is done by reading the posts above yours

 

You don't have a modern GM that doesn't have a filler cap on the radiator. Just remove the radiator cap, turn on the heater and wait till you start to see the coolant circulate once the thermostat open and continue top off until the bubbles stop and the level is consistent. On those modern GM's they must be vacuumed down then sucked in....you don't have to worry about that kinda of BS system....

 

It takes awhile for my heater to even kick on. What do you mean about GM

 

I have the VG SOHC

 

gm=general motors

park it on a hill open up the radiator cap, run the engine with the cap off and top it off as air leaves the system and the fluid level drops

 

why? its a great engine. it just has some... temperaments that have to be worked around...

 

either way, you left out the part about putting it on a hill on your first 'detailed' post. which is really important. we didn't put matt's car on a hill (he was in a rush to go see his gf so he said "whatever i need to go NOW, i don't care if the heat works" and now it's winter and he's eating his words ) and his heat doesn't work at all, even tho i ran the car with the cap off and heater on and squeezed the upper hose and STILL no heat.

as for the "you can't flush at a truck yard" there's an easy way to fix that. Flush it where you can, then fill it up as best you can on flat land, THEN go park it on a hill (truck yard is just one example. if you are in the mountains then finding a a hill is no problem at all.)

 

say what?
we have no issues refilling a GM with bleeding other than the minivans, which suffer from the same malady as the max does. The heater core is higher than the cooling system fill point.
the raising of the front end is a way to make the fill point the highest point in the system so all the air can escape.

 

 

General Motors

 

I think your defending them (GM) for their older products, not their newer, nonradiator cap designed coolant system with no bleed ports and only a reservior/overflow tank with plenty of hiding spots for air and self destruction.

 

nope even the new systems apply the same rules.
unless you are refering to 2005 or newer (haven't seen any in the shop yet)

 

Friend of the family been running a radiator shop for over 20 yrs, in which my dad worked @ for about 2 -3 yrs and always complained about the late model domestics and how you had to vacuum down the systems in order to fill them completey and avoid the air pockets that get trapped inside the block + heads, since there are no bleed ports @ the highest point nor a radiator cap nor a highly elevated recovery/reservior tank.
Thanks for the conversation and info.....

 

so u heater workin now?

 

Vaccuming is the easy way. it would work on the max as well.
it is not NEEDED though. you can jack up the front end just as well or get creative. we tend to get creative.

 

have = hate?

 

silence.I had just woke up

 

i did the hill thing and the bleeder valve and gave it gas. a lot of air came hissing out of the valve gurgled air and coolant then finally just coolant.
