I remember reading a post about cutting a hole in the heater core case to vacuum out the junk that collects after time in a Sammy. I have tried the search function, but get nothing. Does anyone remember where to cut the hole? I think it was high on the drivers side, but don't want to destroy the core.

TIA

It's over on izook.

Thanks Bob, I knew that I saw it someplace!

Does this work on a Sidekick too?

My truck still blows out some good heat, but the air flow aint as good as it use to be.
