![]() Many postings about Techstream and miniVCI cables over at ToyotaNation. The manual activation will likely be accomplished w/ Techstream software (via min VCI cable, available from Amazon/fleaBay) or a service caliber OBD2 code reader. ![]() The heater control valves and heater pump can also be manually activated too. Many times they will learn doing it on your car the first time! Doesn't this fact make you feel good knowing you are paying a shite ton of $ for someone to learn by doing it on your car?ģ) If OP gets the Factory Service Manual, he can see the step by step procedures listed and determine if he is comfortable to DIY.Ĥ) W/O even seeing the service manual, I forsee the coolant refill process on a RAV4 hybrids w/ an elec water pump actually being a lil easier! How/Why? The elec water pump will likely be activated to force coolant movement, and w/ that, air bubbles. Sometimes at a trade school (not necessarily on a Toyota Hybrid). A design that was eliminated on Gen3 Prius and all other Toyota hybrids in USA and CAN that followed.Ģ) The techs learn somewhere, as they weren't born w/ that knowledge. The Gen2 Prius cooling system is still the MOST complicated and a PITA to purge air due to the "thermos". Can anyone confirm this?Ĭlick to expand.1) I can do better than the dealer! Many stories of overpaid dealer service techs f'n it up on the Gen2 Prius (20004-2009). Below is a picture of the draincock I believe needs to be opened to drain the old coolant. I believe on the Rav4H it's actually connected to one of the hoses. ![]() I believe to drain the old coolant, we have to locate the radiator draincock which is typically found on the bottom of the radiator. Does anyone know how much coolant is needed for the Rav4H? The coolant is sold in 1 gallon jugs and I'd like to know how many I should have on hand before starting the process.I believe the car will take approx. or 50,000 miles (whichever comes first)Ĭoolant: I'll be using Toyota OEM 50/50 Prediluted super long life antifreeze/coolant (pink cap)ġ. Interval: First change should be at 100,000 miles or 5 years (whichever comes first), after that, every 5 yrs. ![]() This information may also be helpful to others when it's time for them to have their coolant replaced. I'd love some constructive feedback from anyone who has experience with DIY engine coolant changes. After much research, below is what I've found. I've been reading a lot of different information about when one should change the engine coolant. ![]()
