    LB7: slow heat

    I have heard possible air lock, but can't resolve I've tried filling then Turning on heater to Max and go thru gears for RPMs to build up but when it Starts to heat up it goes overboard and leaks antifreeze again

    LB7: slow heat

    It's leaking from reservoir, it passed the head gasket test, it's really weird It seems like right after it leaks out and the low coolant light come on it runs fine, until nextday then I have to rev up again but it won't spill as much!!

    LB7: slow heat

    my 2004 truck takes long time to heat up, and sometimes spills antifreeze,the gauge will stay at 180 for a long time until i rev up engine then it shoots up to 230 or so then calms down, i keep adding DexCool but getting expensive,could use some advise.
