so leaving my work in a snap freeze today, i realized that my car was blowing cold air, even when the heater was cranked all the way up. i was completely out of coolant. i ran to the gas station and grabbed some. accidentally filled up my overflow tank ALL THE WAY, like an idiot. My dad came and helped me, cause he was awake nearby, he bought me another bottle of coolant. we filled up my radiator and let it idle for awhile. the window defrosted, but my car still wasn't blowing any hot air. we decided to drive the car to make sure that i wouldn't overheat. the car did fine, we got it home. it finally blew luke warm on the way home. but nothing as hot as usual. when i looked at it later before work, it still wouldn't blow any hot air. we bled the system, and there was alot of air in the system, but that didn't seem tot fix the issue.

now while the car is idling, the hose that takes the coolant into the block is cool and the hose that takes the coolant out is hot. am i clogged somewhere? is my blend door(i believe its called) disconnected from the switch? is my heater core bad? should i get a full system flush or should i try bleeding it again? any help and ideas would be great.

basic troubleshooting, which you kinda did, should lead you to the thermostat. just my 2 cents, you might want to keep up with basic maintenance on your car better, coolant doesnt just disappear overnight (unless you have a bad leak, and then you would see it on the ground)

andrew.white

I get that. My cap was crooked on the radiator which caused the leak. I don't neglect my car. Simple mistake. Had to go to work, didn't really think anything of the cold air at first until it became really apparent. The car blows luke warm air while driving, its just while its at idle that it gets ice cold.

here is what i would do..... replace t-stat (cheap), radiator cap, and bleed, bleed, bleed, ....

So, I can't tell from your posts but did the engine get to a normal temp? If it didn't its most likely the thermostat. If the engine did get to temp it's more likely an air bubble problem. If you think the radiator cap is damaged, do a pressure test. I am guessing you can rent a pressure tester.

Either way the car is hard to bleed if you don't follow nissan instructions. It's apparently easier if you have a vacuum bleed system, never tried this way, or a , I have had good luck on other cars with this system, along with following Nissan's instructions.

Isn't their a bleeder somewhere in the back of the engine by the firewall... I remember reading something about that, should show up with a search..

andrew.white

yeah there is. i have revved the car to 3k rpms and held it for ten seconds and then slowly opened that bleeder valve to let the air out three or four times. the car warms up during and immediately after revving, but it cools back down after a few minutes

andrew.white

the engine gets to normal temp. where would i get a pressure tester? like o'reillys or auto zone or a specialty shop? what are Nissan's procedures for bleeding the system? cause someone on a similar thread said to have someone rev to 2 or 3k and hold it for a few seconds while i slowly open the bleeder valve.

Follow the tips already given. Jack up the side of the car with the bleeder. Might take a ton of times before all the air comes out. T stat and cap are cheap.

andrew.white

so jack that side of the car up and then follow those steps? run it tile it warms up, rev it, then open that bleeder valve? and just repeat?

There are two kinds of threads you'll find on this topic. A few describing the proper technique and tools required, and then a whole crapload of threads describing failure due to not reading the other threads, or the FSM, for that matter. Guess which type of thread this is.

andrew.white

whats your issue fam? i posted to get thoughts as I'm sure others have had the issue and done other things besides Nissan's SOP for how things go, like jacking the car up, or opening the bleeder valve, which isn't in the SOP. still fairly new to the site. so why don't you link me to the correct procedures then or actually help.

andrew.white

cause there was this post which is of a Nissan bleed SOP. but i mean, i only failed cause i didn't do this right?

Look,at the thread "coolant purge nightmare". There's one of these coolant threads maybe once a week it seems, and before you do anything, you need to use the search function and read everything you can.
