1987 Mazda b2600 coolant issue
My 87 Mazda b2600 has a coolant leaking problem, when I start it up coolant seems to be leaking from a weep hole on the drivers side fender well. Not sure if this is from the heater core or what. No coolant inside of the truck on the carpet and no visible leaks from and surrounding hoses

Get a loaner cooling system pressure tester from Autozone or similar. Pump up the pressure to like 15 psi, look for leaks.
Can you temporarily bypass the heater core inlet and outlet hoses to each other to see if the leak stops?

Bypass
I temporarily bypassed it. No leaked out of the fender weep hole. Have not had a chance to pressurize system

If the heater core or in-dash stuff is leaking, you want to see this unless you can live with it bypassed.
Remove the dash???? Are you nuts???
