Assuming you've already replaced the heater t's but just a reminder to remember they may be in bad condition. Hook up the garden hose and flush until all clean. Stick it on the heater hose closer to the passenger side of the vehicle between the t and the motor. If you search my name for posts on Coolants you'll see some more in depth replies I've made on the subject. I found that I could allow the open end of the hose to rest in the raised position and then turn it down towards the catch container every 5-10 seconds to remove another splash of old coolant from the engine block.
I know Toyota red and Toyota pink are compatible with each other well, it really depends on who you ask, but let's just stipulate that it's settled , and I know there may be other suitable coolants that can be used in the Toyota system. Hopefully you can get your local dealer to come down. The manufacturer guarantees it for as long as you own your vehicle if you do a flush and fill. My 2004 V6 calls for the pink Super Long Life coolant, for example. I will check for leaks first. I would just make sure it is the Super Long Life Toyota coolant, which has a lot more anti-corrosion additives and water pump lubricant in it.
Did you remove the engine block drain bolt, but nothing to speak of came out? The quantity depends on the model. First I will recommend that you find if there is any leaks causing your coolant to go down. Finally, is there anything special about the inverter coolant? Rear Brakes You should visually inspect them every 5,000 miles or 6 months and measure them every 30,000 miles or 36 months. See if your local dealer will price match Toyota dealers who sell online. You've contaminated your system with the incorrect coolant by placing a generic silicate coolant in your vehicle. I don't think that mixing and matching is recommended. The oil filter element kit includes new filter cartridge, two new gaskets, and the temporary oil filter drain pipe.
Refer to pages 50~51 of the 2016 Prius Warranty and Maintenance Guide. I need to top off both my engine coolant and my inverter coolant. I'll know it's 100% compatible. Some people would recommend draining the entire cooling system and flushing it out with distilled water. Double check that the lower radiator hose is attached securely to the radiator by pulling on it firmly to see if it moves. If you do a proper flush there won't be enough of the old antifreeze to even matter.
Others say no, the Toyota red isn't compatible but with certain other brands Peak Global seems to be the most often cited brand. The best you're going to get is opinions. I don't think that mixing and matching is recommended. Re-Torque Propeller Shaft Bolts You should do this every 15,000 miles or 18 months. Also remove the cap from the white plastic radiator overflow tank in preparation for topping it off with new coolant later on.
And why go with another brand? Almost as important: it's pink, and all the other stuff is green, it'll end up some strange colour, lol. I don't think using the Peak Global Lifetime in the inverter would be any different than using it in the engine. Here in Europe we don't really have access to organic acid coolants with phosphate because of hard water restrictions. Also the coolant system is a closed system. Failure would be a major expense. I don't want to do that with the inverter since it will be 60,000 miles before I need to flush and fill.
Let the old engine coolant drain out of the radiator and out of the engine block from the open end of the lower radiator hose. When you see the level begin to drop down out of sight, use the funnel to add a little bit more new coolant into the radiator. They both use the same coolant. So far, the few times I have had to go to a physical dealership, they have all come down considerably from their asking retail price, a couple times they have price matched. Do they both take the exact same coolant type? It is always best to take your truck to a mechanic in the event you are unsure of what you are doing.
I purchased a gallon of the coolant with free shipping on Amazon. What I haven't been able to find is many who have used it in their Prius. Drain the radiator and drain the block or pop one of the hoses off the lower oil cooler to be able to drain at least a couple of gallons. I suspect it is sealed and is meant never to be self-serviced. Carefully and slowly pull off the lower radiator hose from the spout on the radiator. We are getting away from the big picture here though. Most aftermarket stuff that's branded to be compatible should do fine.
