I wonder what the harm would be if I disconnected the hot water lines leading to and returning from my heater core.??? My maro has been getting really hot lately and i'm thinking that if i do this the coolent will get circulated quiker and help keep me running cooler....
.
Does anyone have any ideas on this????

if you still have the vacume valve hooked up, it shouldn't be circulating coolant to the heater core anway.

Another thing to consider, is that with the heater core, you have more coolant in the system, and the heater core also acts like a small radiator, your cooling should be better with coolant flowing to the heater core.

what he said ^^

now if u want to keep the engine cool turn your heater on full blast. only bad part is u might die from the heat

if it is getting hot, i would start by making sure the cooling system is in good shape. Pressure test it, and flush it. Also, make sure your fan(s) are working and that the shrouds are there, along with the air-dam.

are you running it without a t-stat? if you are, put one back in.

No t-stat causes overheating. Coolant flows through the radiator so fast that it is not cooled by the air movement. Spend a couple bucks on a 160* stat and some orange goop, and you're good.

I honestly wouldn't go that cold. I would get like a 180-185 ish. Also, make sure you have the air dam on the car, and that your fan is working, and that you don't all the air out of the system. maybe a new radiator cap, if you aren't holding pressure.

What temp is the t-stat you pulled out?

The air dam is a plastic 6" x 2.5" plastic piece that hangs below the radiator to force air up into the rad.

Bypassing the heater core wont cool anything.

Not enough timing will cause you to heat up too. Also a worn out water pump can cause over heating.

My 89 has been missing the air dam underneath since I bought it. I've only overheated it once and that's when the fan motor ate itself. It indirectly forces air through the radiator by creating a low pressure area under the engine. I need to get off my butt one day a go get another.

My '85 IROC hated the freeway without the air dam. Especially on 90º+ days. Suprised yours doesn't! Mine even had the goofy hypertech chip that turned the fans on at like 100º.
