2003 GX470 with 150k miles. Pump and belts done by PO at ~120k, and I just replace the thermostat inlet housing o-ring which I though was causing the leak due to visible seepage.
After filling the reservoir to the full line, the next day it's back to half full. Coolant is visible on the front passenger side of the engine where the head mates to the block. I removed the PS bracket and the belt cover but can't really tell if the leak originates further up. I can also see wetness on the block under the manifold on the same side so assume it's related.
This has been going on for a while but the leak is getting more prominent. Any thoughts on the source? Hoping it's the water pump and not a head gasket.
Don't know if the engine ever overheated but it runs great and temp is always at mid-point on the temp gauge.
