black smoke coming out of my exhaust and is running hot

What is your question?

after I left work last night my needle was reading hot way up there and after 4-miles into my 8-mile drive home massive black smoke was spewing from my exhaust pipes and smoke from under the hood and it died out about 2-blocks from home it started back up after about 10-minutes I just had the Heater Core and Blower Motor replaced 2-weeks ago
