Hi, our Blazer started to make a sloshing noise when I turn a corner or
accelerate hard. It sounds like it is coming from behind the glove box. I
checked the AC drain and it is draining ok. I also checked the antifreeze,
it is still full and no wet spot on the carpet. Any ideas before I start
disassembling things?

Thanks,
Mike

Backflush the heater core.

Remove the heater hoses from both ends of the heater core, then hit the core
tubes with a garden hose. Can't remember offhand which line is which, but
basically you want to flush with a garden hose in the opposite direction
that coolant normally travels.

Got it figured out, it was the radiator cap. I'm going to go ahead and
flush and refill the coolant also. Does the radiator drain plug take a
special tool. The drain plug is plastic and looks like an anti-theft screw
end, not a thumbscrew end.

Thanks,

Mike

Mike,

It looks kinda funky but it's just your stardard petcock. It should come
loose with just your hands on it. If the coolant is draining really slow
thru the drain hose run a screwdriver up into it <the hose that is> to
loosen up the junk that might be slowing it down. I've found they have a
tendency to collect junk up in there................
