Hi All,

My old radiator core support was pretty much Swiss cheese. I found a pretty good used one that has a few small holes in it. These should be easy patches.

I am impressed by how much of my original core was eaten away and I do not want to have to come down this road again in a few years.

Is there any preventive measure I can take on the replacement care? Drain holes? Spraying wax inside it?

Thanks!

Had mine powder coated. Looks the same as when it was coated 20 years ago, but it doesn't see much rain either. T

I actually drilled some small drain holes in the bottom of the support. On my 78 if you looked at the majority of the rust, it was along the bottom, where 2 pieces of steel were welded together. When I took everything apart it was rusted inside those 2 pieces so I figured water might be getting in there somehow with no place to go. Will have to wait another 20 years to see if that made any difference.

Its JUST a car
You dont want it overheating;a car is NO GOOD if you cant trust it.

Call Dewitss and stop watching your gauges. If anyone buys it no matter what they say they will be happy theres a sweet brand new alum radiator trust me
nothing lasts forever. BTDT stop throwing your money away. Tit job wont make an 80 yr old look any better

core support. not core.

If you want a cheap and cheerful way to minimise the core support rusting from the inside you could do what I did if you have access to an air compressor. I used a shop spray gun like the one in the pic to spray fish oil inside the support through every bolt hole or gap I could find, the high-pressure air atomised the oil and ensured it coated all of the inside surfaces.

When mine was out it seems to me I uses a funnel and poured a bunch of tremclad type rust paint inside a couple of the holes, taped them closed and kept turning the thing over and over to run the paint around inside everywhere then opened the holes and drained out the excess.

I did that will all of the crossmembers as well.

Eastwoods sells a chassis spray kit with a hose that attaches to a spray can with a nozzle on the end that sprays sidesways, works fairly decent (I used on inside of frame) but doesn't ensure that the paint will get inside all the crevices where it needs to
