Airlift for Inverter and Engine Coolant

thanks, great info!

 

Just bought an Airlift and did the same. Exceptional results.
But did not solve the problem. I changed the thermostat as I get no heat from the ICE. Changed the coolant as well.
Still no heat. I will throw a water pump at the problem next.

 

Sure beats the time consuming and tedious Toyota specified revenue generating method that the stealerships use.

 

I did coolant changes on both circuits this fall, third gen but I believe similar, just following the Repair Manual procedure. With the engine, you refill to B line on reservoir (about an inch above full line), install the cap, run the car in maintenance mode till fully warm. During that time the level in reservoir slowly drops.

learned a trick:

I thought it had warmed sufficiently, coolant in reservoir had dropped “some”, so shut it down and crawled under (front was raised and under-panel removed to facilitate the inverter coolant drain), to reinstall the under-panel.

I felt the large radiator hoses and discovered they were still stone-cold. I started it back up in maintenance mode, crawled back under, just lay there, occasionally checking those hoses. Eventually, presumably with thermostat opening, they went from cold to toasty. Done.
