    Default Coolant smell-mist on passengers side valve cover(maybe)

    Been a while

    Got a question-will also post it as new.
    Smelling coolant again-but not losing much judging from radiator level-which is slowly dropping.
    I have noticed the front half of the passenger's side valve cover-is "wet" looking-certainly different-clear demarcation-than back half-like maybe some liquid has been misting on it-
    Now it isn't actually wet-but it definitely has had something wet-misting or spraying on it.
    Never actually wet-but you know what I mean.
    I put paper around that cheezy heater hose to mainfold fitting-thinking it might be spraying leaking-but it wasn't wet after short ride?
    There are other hoses fittings there-any ideas?
    Thanks

    PS 221,800 98 Suburban bought 6 years back 195,000 miles-it has been a winner-only good thing that has happened to us-$$ wise-in the last 10 years.
    Going to do 3000 mile round trip-New Orleans to Flagstaff AZ in 2 months-so got some repairs to do-
    luckily 25 days-first SS payment(still work-took early 62-need the $$-it will be a HUGE help) 1998 suburban-

    Bunch of things-brake shoes 3 tires oil leak(looks like upper ft of oil pan or cam cover) drain trans fluid-probably change coolant-runs well-still gets good mpg-probably should do plugs wires-old owner cheaped out-aftermarket wires-he rarely cheaped out-took excellent care of it.
    Thanks again(yeah-entirely possible intake gaskets again-idiot did work 2-3 years ago-screwed up 3 screws bolts that I know of-so probably many more)

    I would rent a pressure tester from a parts store and pressurize the system. If it is leaking you should find it rather quickly under pressure.

    Thanks.
    Maybe Autozone?
    Now if it is leaking-how will I know-since plenty of the tubing-and top part of radiator-might not be filled with coolant-
    will there be an obvious shhhhhhhh noise-little spluttering of slightly wet stuff?? ?
    Thanks

    Yep, they along with any other big chain store will have them under their "free loaner tool program". You will hear it leaking out.

    Hey charlie good to see ya again.
    I think Pikey hit the nail on the head.
    A pressure testor is the easiest way to check cooling systems without having to deal with a hot engine.

    Pikey TB thanks.
    AZ it is.
    Hey-does a pressure tester work if it is a intake manifold gasket-again?
    No reason to think it is-other than I have no faith in the work the guy who replaced mine did-
    and they leak commonly.
    Seems like it would be tough to hear see it if it was leaking there.

    Hey love the kitten-probably said that before!!(we have 4 cats one greyhound-lotta pets)
    Nice to be back!
