Re: wierd cooling system problem noise ?
garyd1961 i did try the heater core plumbing like you siad and GM them self said when i called them . it cut down 90% of the noise /smell but didnt NOT fix it for good .
so i plumbed it with the bypass hose as someone else did years ago on the link i posted and so far 20-30 miles in 2 days of driving we are good .
and the pics posted show why you need the bypass hose as the heads are not cast and setup for the flow like old .
