One week ago, I tried to do a regular maintenance including oil change and the tires rotation. Floor Jack slipped a little before I placed the stands. I have a rule that never lie below the car without the floor stands. Therefore, I was not injured at all because it is a minor slip and I was not beneath the car. However, the jack slipped into the drain faucet of the radiator. So the coolant was leaking from the cracks around the faucet and pouring on the ground. I stopped the leaking temporally by paste some epoxy but it was never a long term cure to the leaking. So after I changed the oil and completed the tire rotation, I order the genuine radiator (Part No.: 16400-0P370
RADIATOR ASSY) from toyotapartsdeal.com for my 2017. It cost me a fortune but I would rather purchase a genuine part for 100% fit. To remove or to install it back was not difficult for me. Also, I took this chance to rinse and wash out the bug bodies out of the AC condenser and even zip Stainless Steel Mesh under the grill to protect the condenser and radiator. It is not so bad given what I have done.
easy to disconnect
Bugs...
drain first
remove the tranmission hose
