![]() ![]() If the material is not flushed out completely, it acts as sandpaper as it flows through the coolant system, negating the anti corrosion properties of coolant. I think the issue is with neglected cooling systems where the flow of coolant caused by a flushing machine can dislodge matter that can get trapped in the water pump or thermostat. Follow the manufacturer's instructions and you will not go wrong. And to replace the coolant timely, as Lugnut points out above. The important thing is to flush out the old stuff as much as possible. All my other Toyota products have SuperTech universal coolant. At 230K I had the water pump replaced as preventive maintenance - van has never had cooling issues. At 90K, I switched to a universal coolant (Prestone, I think) in our 98 Toyota Sienna. It's OK to trust the label of a reputable coolant manufacturer if they say their coolant is compatible with your vehicle - they wouldn't be in business if their product was snake oil. Universal coolants are formulated to be compatible with a wide range of coolant systems. The purpose of these chemicals is to protect the metals in the cooling system and inhibit corrosion. Specifically, a coolant with phosphate but no silicates, borates, 2-EHA, or nitrites - I might be missing a chemical there. Toyota specifies a P-HOAT (phosphate hybrid organic acid technology) type coolant for current models, back to mid 1990's. (12,500 miles) or every 2 years (depending on what comes earlier).Click to expand.I say phooey on the the Toyota coolant. ![]() It is necessary to change the fluid in the CVT (in this case, Aisin fluid is indicated, since it is they who produce the CVT for Toyota) every 20 00 km. It is written in Japanese, but everything is clear. Here is an example of a Toyota Corolla with a CVT. Maybe for this reason, Japanese cars with CVTs do not require repair? (12,500 miles) or every 2 years (depending on what comes earlier). I can't imagine not ever changing the coolant on a 1800. I do have a 1500 and it is recommended that the coolant be flushed every two years. So, on the back of all these Japanese cars there is a nameplate (sticker) on the frequency of replacement of transmission fluid. Don't have an 1800 so I imagine someone with one will be along shortly. We have a lot of cars from Japan in Russia (which were originally sold with right-hand drive inside Japan, and then bought and brought into Russia by used vehicles). Japan has interesting transmission fluid replacement standards. Therefore, I have a mileage of about 40,000 kilometers per year (that's about 25,000 miles). I myself occasionally travel by car from Moscow to Europe (to Poland, Germany, Austria). On average, people travel 25,000 to 30,000 kilometers a year (15,000 to 20,000 miles) per year. More detailed information (with diagrams, photographs) is here. The volume during the shift is 3.7-3.9 QTS (this is 3.5 - 3.7 liters). The laying of the pallet (Gasket, oil pan) - 21814-RJ2-003Ĥ. The fine filter behind the oil cooler (Filter) - 25450-P4V-013ģ. And behind the oil cooler (it is on the side of the variator, the diagrams below explain and show in detail) the variator fine filter changes.ġ. The variator (cvt) pan is removed, the pan gasket, the coarse filter (in the pan) are changed. If you regularly drive your vehicle under these conditions, have the transmission fluid changed This requires transmission fluid changes more frequently than recommended by the Maintenance "…Driving in mountainous areas at very low vehicle speeds results in higher transmission temperatures. ![]() In the instruction manual (in the manual - ) it is written verbatim: Oil change intervals are once every 40,000 km. Frequent oil change in the variator (CVT) - significantly increases the residual transmission resource. ![]()
