Ford Focus LZ Sports Heater Core replacement

[charliedelta]

I have had a minor coolant leak on the 2015LZ. I replaced the coolant tank and cap.
Then a local mechanic indicated that the heater hoses were leaking and he changed them.

Now 1 year later I am getting this slow coolant leak again. Along with hearing the gurgling water noise like there is air in the system from behind the dash when starting. I did bleed/burp the coolant. The leak requires a top every couple of weeks depending on how many K's I do.

I am told that the heater core is a major job. I cant find moisture inside the car on the car on the floor nor can I see any leaks. I bought a pressure tester kit and when I pressure tested it it was static. When I put the car the ramps I can see coolant drip streaks on the underbody splash shield.

Anybody have further ideas that I can explore. Doing a heater core and hoses is beyond me.

Any suggestions?

Thanks

I would also check the water pump as they can leak from the shaft seal

Thanks I never thought about checking that.
