Are you sure it needs to be replaced and not reversed flushed?

To reverse flush the heater core there are 2 hoses next to each other that go from the engine through the firewall disconnect them and with a garden hose run water through the nipples they where hooked up to.

Most heater cores don't need to be replaced unless you see water/anti-freeze on the passenger side floor mat.

By drive belt do you mean the accessory drive belt ? Or are you referring to the timing belt ? A broken accy belt should not cause the car to not start unless the belt slapped around and broke something in the engine area. Check all around and under the front of the engine for damaged wires or wire connections to engine sensors that may have been damaged by the slapping belt. If its the timing belt your talking about then you need a mechanic .

One of those secondaries will be the feeder for the ignition switch. The other may be for the fuse box, or may be for something else that is powered at all times-like the headlight switch. Here's how to clean it up:
First take off the negative battery cable-negative first to avoid sparking. Now you can pull off the positive. Most new positive battery cables only come with one "pigtail" or secondary insulated wire. But if you tell the parts person you have a Volvo and the year, they may have a cable specifically for your car with two secondaries. Or you could try the dealer for the right cable.
Barring that, if you just want to fix your old cable without buying a new one, you could take the stripped wire and crimp a new eyelet connector on the end and wrap the bare portion with several wraps of electrical tape. Now put the big cable terminal on the battery post, take off the nut on the tightener bolt, put the eyelet connector over the bolt, and tighten the nut down on the bolt. Now both secondary wires are attached? Put the negative post on and tighten it down. To avoid corrosion at the posts you can smear a little petroleum jelly (vaseline) on the post and cable connections, if you want.
