Sounds like you have a hole in your heater core, if its coolant. If its clear water its A/C condensation which is normal even when your not using it as it cycles to keep the seals lubricated.

I have white smoke/steam coming from my air vents and antifreeze leaking from a spout in my firewall. Any ideas/solutions?


Your heater core is leaking steamed antifreeze into the vents and possible out the firewall,where the heater hoses connect to it. Have that checked out.

My 1999 jeep wrangler is over heating, smoking and losing coolant , I replace the heater core, replace radiator, replace thermostat and thermostat housing still over heating


It appears that you have a blown headgasket, a failing water pump, or a cracked block.

There is also the possibility of a freeze plug failing & leaking there.

You can bypass the heater core until you are sure your engine problems are corrected so as not to damage it from excessive pressure.

You'll need to reassemble everything and pressure test the system instead of starting the engine, to see where the leaks are.

Good luck !

Condensation under dash when you use the air conditioning


heater core and evaporator drain tube under the dash stopped up. go underneath the vechicle firewall under hood area. go around heater cores coolant hoses some where below that area you should have a drain tube opening, take a shop vac tape small hoses like vacuum line 3/8 inside diameter vacuum out debris in ac drain tube that should help inside leak problem.

I did perform a pressure test on my 1999 Buick Century (3.1) and in doing so noticed coolant leaking somewhere from the backside (facing the firewall) of the engine. With no access to a lift, it was...


freeze plug or intake. Most auto parts stores sells a red dye you can add to the coolant. Then you need a ultra violet lamp to see where the leak is. The dye will show with the UV lamp with a bright glow

Water leaking on passenger side of 1999 jeep wrangler


If you look on the engine side of the firewall on the passenger side about even with the bottom of the heater box, you will find a short pliable stub hose. you can clear it by rolling it between your fingers or using something soft and inserting it into the hose (using anything hard or long can damage stuff inside the box) Once cleared, you should have no more problems.

HEATER CORE REPLACEMENT!


I have a 1993 Jeep Wrangler YJ...My heater core needed replacement when I bought it about a year ago. I made the mistake of taking apart the dash to get to the heater core. DO NOT DO THIS!!! It is actually 4 screws that you must take out from the inside of the engine compartment on the firewall. Then it will come right out. Have fun!!!
