Coolant leak poossibly heater related help.

[killj0y]

Ok so, not too long ago my heater control valve went out and after I replaced it. Now I don't see any coolant leaks anywhere and the truck runs fine, no signs of engine damage or anything but I do have to top it off every so often, ie a gallon of coolant has lasted me a few months from just topping off a cup here a quart there every month or so. The only thing I've noticed abnormal is that when i run the heater I do smell sweet like antifreeze.

Before I go ripping into the dash/heater core is there any tips where to look or just general troubleshooting to avoid ripping everything apart?

No one can chime in?

Any hose clamps that need tightening? JW. Or, clean out heater core and try liquid solder, let dry and check for leaks. Doesn't sound like a huge leak, but it's starting...

Yah , First thing I would look at is the stuff I just worked on. I dont know much, but I do know I have a mind like a sieve.
