I've camry 2001 LE, with 149K on it. Recently, I noticed coolant leak from the radiator and replaced the radiator. I still was loosing coolant little bit, so performed coolant pressure test. The upper radiator hose was leaking, so replaced that.
I'm still losing small amount of coolant in the reservoir. I again did the coolant pressure test today, but didn't detect any leak. But the pressure on the gauge dropped very, very slowly.
What would be next best thing to do/replace? Thanks!
