I watched the video again, so if i don't have a temp gauge. Would be okay if I let the engine idle for 30min and just wait for the cooling Fan to Turn On and Off TWICE? is it safe to say that there are no more bubbles?Thank you again.
Yes that should be OK. Sometimes may take longer than 30 minutes. But if the cooling fan cycles on and off at least twice during the bleeding procedure then you should be OK after that.
I have a few questions. First, there's an auxiliary drain plug located on the bottom of the block. Is it necessary to open that up to get a more thorough drainage? Second, what are your thoughts on flushing the coolant lines out with regular water before refilling it with new coolant? Third, I remember flushing the cooling system of my old '95 Ford Contour and I had to replace the thermostat because for some reason, exposing a used thermostat to open air caused it to become permanently stuck in the closed position. In fact, that happened more than once. Is that normal?
Hi, I have an 03 Corolla with 150,000 miles & have never drained & refilled the antifreeze coolant. Should I do it with this current mileage? If so, would you recommend a flush or just a drain & refill?
You could do a drain and fill if nothing is clogged up. Otherwise, you can flush the system out with a garden hose or fill with water and run the system for some time and drain and fill with coolant in the end. There is no harm in doing it now. Better to do it now rather than never.
So..I had the coolant drained & refilled at the Toyota dealer & they messed up my radiator!!! I bought it home & it was leaking! They offered to replace it, but my question is, when you do this do you have to replace the water pump & thermostat as well? I have an 03 Corolla with 150,000 miles..
It is not necessary to replace the water pump and thermostat if they are not leaking and/or if the water pump is not noisy. But say you replace the water pump then it doesn't hurt to do the thermostat as a maintenance item with that mileage and age. Unless you are having problems with those parts I would leave them alone.
@moosemobileautorepair how many jugs did you fill it with, I was gonna drain and fill it twice with two jugs but it looks like you used two just for one drain
Oh mann !! I have become your 500th follower haha 😂 if you want to buy me food please let me know 😆 thank you for sharing your video it is very helpful for me who doesn't know how to flush the radiator, I also saw your mistake which is that your car has a lot of dust 😜 love from Malaysia 🇲🇾👍
1 gallon should be enough. You can get another jug as a spare just in case if you need more coolant. You can suck out the reservoir with an extractor tool or syringe of some kind or just drain it from the hose at the bottom. Realize that this procedure is a drain and fill only. It just drains the coolant from the radiator and reservoir itself and it is not a complete drain of the entire cooling system as there will still be some left over coolant inside the engine block itself. You may need to top up the coolant in the reservoir later down the road in a few weeks or so to adjust the level after completing this service.
I noticed that you also posted a video for 2009-2013 Corolla with the same engine 2ZR-FE as this one. The procedures in your two videos are slightly different. Do these differences matter because of different years even with the same engine?
Same procedure for both. You can follow whichever video as long as you bleed the system out properly of air and that you are getting good and strong heat in the interior of the vehicle.
You can, but coolant will spill everywhere while bleeding the system when it warms up. You have to make sure to keep topping up the coolant as you're bleeding it. You really should have the funnel kit as it helps to eliminate any air bubbles in the system because it can hold reserve/extra coolant in the funnel while bleeding. The whole kit costs probably 40 to 50 bucks for the funnel and adapters off Amazon.
No, not at this age maybe when the vehicle is 10 or more years old. The thermostat is a little harder to get to on this vehicle and may require the alternator to be removed for access. I'd probably replace it if say you are doing a water pump or something related then it would be okay to do it. Normally, if you are not having problems with it I'd just leave it alone in most cases.
thanks bro Toyota try to charge me $250 plus other fees with it to do this ! I can do for under $40 if you have a brake fluid change video let me know. thanks.
Thank you for the video! If we just drain the fluid from the pet cock valve will it drain all the coolant out or will there be some fluid in the engine?
Hi, thanks for your comment. This will only drain coolant from the radiator only. You will still have some left over coolant in the block. You would have to remove the radiator hoses if you want to flush the system out with a garden hose or use a coolant exchanger machine. Ideally, if you change your coolant often enough then flushing is not necessary.
😂 There are renters next door and so the previous neighbour next door moved out and so a cleaning lady came to clean the house and she asked me if I was a mechanic and had some questions to ask. That's right. Thanks for picking that up.
@@moosemobileautorepair thanks! I am color blind, not sure if my 2016 Corolla eco has pink or red coolant, I purchased used with 60k miles on it, does the color make a difference?
Yes, the colour makes a difference. Before 2004 Toyota had Long Life Coolant which was dyed a red colour and had to be mixed 50/50 with water. After 2004 Toyota introduced Super Long Life Coolant which is pre mixed 55/45 do not add water for this coolant. Toyotas now all use the pink stuff.
@@moosemobileautorepair thanks again, need to top it off but didn't know what to get, level is low, low enough to not see the antifreeze color, can't tell the difference between red and pink just looking at the reservoir, Google didn't help none and the guys at the auto parts store will sell you anything. Could have just done a flush and replace to know where I stand with the vehicle but with such low mileage and the process required I didn't feel like that was necessary when a simple top off is all that's needed. I'll grab the super long life pink thanks a bunch.
It's the customer's money, not my money and not your money. The thermostat is close to a 2 hour job on this model. Unless you want to pay extra money out of your pocket then so be it. These are customer's cars and these customers are not going to pay extra labour and fluid for me to do a full flush. You can use a coolant exchanger machine to do a full flush, but all of that costs money and space to keep and do. Most people just want to do what the basic maintenance service is. As stated in the title this is a "Drain and Fill." This is not a flushing coolant video. This is just the basic drain and fill which gets most of the coolant out you will probably have 1/3 of the coolant left in the block. You don't need to drain the block if you do regular service at regular intervals.
That is why the first interval is 10 years 100,000 miles and the interval changes to 5 years 50,000 miles for the following changes. I personally drive it a couple weeks and then do it again. That removes the majority of old coolant.
