this is a good video, but I disagree with the statement that if the core is plugged worse it needs replacement. I have successfully cleaned them by putting Calcium-Lime-Rust cleaner or something similar the in core and letting it sit for an hour or 2, then flushing. Works every time, though a dex cool plug might need something stronger.
@r3g3d17 "though a dex cool plug might need something stronger." i have a 97 malibu and both radiator hoses get hot n feel harder (with pressure) then regular....
@r3g3d17 CLR sounds like the best/no brainer solutiuon-- but as the bottle warns against using that product on brass, aluminum and copper-- how long can it sit before you "melt" solders etc.?
@Metakythera I DID forget to mention that you use 4 to 1 parts water to clr, and only let it sit for a long time if its totally clogged. If liquid can still get through, you only need 10-15 minutes. I've used clr on several heater cores in my own cars, both aluminum, one was over 20 years old and the other only 10, and haven't ever had one or heard of one leaking or failing after having this done to it. I guess it could happen if the core was on the edge of leaking anyway.
@r3g3d17 Thanks for your reply! Here's from the CLR website: Can I use CLR to clean out my radiator? No. CLR should not be used on a car radiator for two reasons. First, CLR may not be compatible with the internal metals of the radiator. Second, it could have adverse effects if the CLR is not rinsed out completely. But that may be just a sort of legal precaution- at other places about aluminum it just says it will take the finish off- I bought some- I think I'll try it with the 4:1 mix.
@superhawkn I have had excellent luck with BG's flush kit. I have had systems so full of chunky rusted coolant that I never thought they would unplug the system. We do a manual flush of the system with a garden hose after 30-45 minutes of the flush it going through the coolant system.
@easyworship The sloshing sound could be either heater core restricted, low on coolant or liquid coolant in heater box which would usually end up with coolant on the floor.
hey im no car guru. i tried looking threw other posts, but couldnt findanyone asking this. yesterday my heat was really bad all of a sudden and it was fogging up the windows and steaming up the whole car. i assumed it was the radiator cuz it had been leaking. but it was full. in this case should i try to flush it or do i need a new one?
@BellumSacrumBellum28 odly enouf it stoped and the heater is working fine and leak stoped. weird... maybe it was just a clog that worked itself out? it only did that for like 4 days
@BellumSacrumBellum28 Check to see if there is any change when you switch from hot to cold on the dial. It's probably a blend door stuck on the cold side.
@csrichardson1 I got it working. I disconnected the core hoses and back flushed it several times. Blows good and hot now. I never really suspected the heater core was bad because it never leaked or put fog on my windshield. Thanks.
I know it's a late reply but most of the time you won't get a check engine light if your car's thermostat is gone. The thermostat car malfunction in an open or close position. In open position you'll experience under heating like what this video is about and it closed position the engine will overheat and that's even worse.
Newer GM with a V-6 pushrod motor? Nothing came out of the hose? The coolant was just a little low. Heater core is the highest point in the system, first thing starved when the level drops. Of course flushing it fixed the problem, because you refilled it afterward. Good job jamming the customer for an unecessary repair, you incompetent turd.
I've got a question... can using a hose directly into the core cause damage? This demo uses quite a bit of pressure and I'm hesitant to use that much. I know you need some in order to flush the core, but I also know it doesn't take a whole lot to cause damage.
@Toodlem I would say that risk is always there however I have never had one blow out in 15 years of doing this. I personally feel if it happens it was either already leaking or would have been soon. If the cooling system is really nasty then I would be more concerned due to corrosion. I would not use compressed air in combination with the water pressure. Most of the time if they are that badly plugged they end up giving you quite the shower!
@MGiants82 The best way is too fill it up with the vehicle off and cap off radiator. Rev engine too around 2-3000 rpm and fill radiator with coolant at the same time. May require two people. Once you have filled to top, install cap and let idle. If vehicle tries to overheat shut down and let sit for couple hours to cool down. Remove cap and fill with rest of coolant needed. I have had to let them sit over night before. This can be difficult for a customer to understand.
@mafia8985 If they are going to pull it out they might as well replace it!! I would just flush it in the vehicle and if that does not work then replace it. I have a customer who's vehicle plugs up every year! He comes back every fall to have me flush it for him. He won't pay us to flush the whole cooling system.
@profleetautorepair I own a 1998 Chevrolet Malibu. I got a problem with my car The heater is not working, it started heating less every day and now it comes air from the thing, but is not hot anymore, and with this temperatures here in Alberta Canada its juts frezzing. Does flushing the whole cooling system will help ? Thanks in advance !
@nikksan First our YouTube handles are almost identical! Second you should manually flush the heater core first then flush full system with heater core still disconnected. If not then the debris will restrict the heater core flow very soon there after.
@profleetautorepair I had my 98 Taurus radiator flushed @ Jiffy Lube, & I've had no heat ever since. I can't afford a mechanic, so I'm hoping to watch enough of these to narrow down my problem. (vent door/motor/heater core plugged etc.). I've had no leaking, but windows now fog up if I turn on the heater.
My heater fan only works on the highest setting, which I've seen is another problem the Taurus seems to have often.
@twistedsledder Yes it did fix the lack of heat. The funny thing was my buddy did not even know it was plugged. He told me afterwards that the vehicle did not have good heat prior to us flushing it out.
@JDMGTP The vehicle only had 50,000 miles on it. The spring style clamps are a thousand time better than worm gear clamps. We have had nothing but problems with cheap ass Chinese made worm gear clamps. We try to reuse them whenever possible.
