Coolant leak help.

[Stuzu]

Recently found my engine temps creeping up. Coolant reservoir empty and radiator thirsty. Topped both up and still am losing coolant. No obvious leaks on heater ts not new radiator cap but from this spot on passenger side firewall?

Any input or experience with what I’m looking at? This is my first time dealing with coolant issues since ownership.

That looks like water out of the A/C drain, not coolant.

Lots of places to check for coolant leaks, and they should be obvious if you’ve been using Toyota red or pink coolant.

You're looking for liquid coolant leaking out and you're also looking for crust buildup, which is also a leak.

How many miles has it been since you last looked?

Old cracked hoses will cause this. You reach a point where they all need replacing. They're cheap and are the last thing procrastinate about.

I once had a radiator with sneaky leaks.

Recently I was losing almost an inch of coolant from the overflow tank every 75 miles and the only sign of a leak my half panicked searching found was a little crust on the front half of the thermostat housing on the top of the hose. I then went to look at my parts rig, which has the same mileage and it had a little crust in the same spot, so that housing was also pitted. Come to think of it that one lost Coolant too, but slower.

So I removed it and where the hose fits over was severely pitted. Aluminum. So I got a new front half of the housing from the dealer for $60 and replaced the thermostat and gasket while I was there. New OEM hose clamp for $5 too!

I didn't think this was 100% of the problem but it was. 1000 miles later I haven't lost a any coolant whatsoever.

I hope your fix is as easy as mine was!

I secondd the crust on the thermostat, cleaned with a wire brush and rub grease on the thermostat housing if is still usable. Check if any heat hoses are rubbing onto something else. I had one rub a hole onto the hose rubbing on the "splash" cover the went to the oil cooler.

Take it to a shop and perform a coolant pressure test if you cant find any crust around hoses.
A friend had a small leak in front of the rad and behind the condenser that we couldn't see at plain sight.
