Narrative:

During climb the fire warning 'fault' light flickered. Captain tested the fire warning and determined we had a bad 'B' loop on #2. Retested with selector on 'a' and got good test, moments later we observed a #1 engine overheat. Proceeded with the engine overheat procedure. When the light did not go out, captain started a turn back to alb and proceeded with the engine fire/severe damage or separation checklist. As we were about to start the checklist, the overheat light went out. We continued to alb, declared an emergency, and landed uneventfully with both engines running. Callback conversation with reporter revealed the following information: reporter stated that the postflt inspection found some grease on the loop connectors on the #1 engine. The passenger were protected on another flight. After maintenance was completed the aircraft was repositioned on a non revenue flight to bos, the original destination airport. The airline said that they did not want the first flight after corrective maintenance to be carrying passenger. A modified ferry flight so to speak. The loop on #2 engine was in proper working order. There was no common anomaly that created these separate indication problems.

Title: B737-300 EXPERIENCES A #1 ENG OVERHEAT WARNING ON CLBOUT FROM ALB. SLOW ENG FAULT RESPONSE TO CHKLIST USE. RETURN LAND WITH EMER DECLARED. FAULT FINALLY CORRECTED ITSELF. LANDED ALB.

Narrative: DURING CLB THE FIRE WARNING 'FAULT' LIGHT FLICKERED. CAPT TESTED THE FIRE WARNING AND DETERMINED WE HAD A BAD 'B' LOOP ON #2. RETESTED WITH SELECTOR ON 'A' AND GOT GOOD TEST, MOMENTS LATER WE OBSERVED A #1 ENG OVERHEAT. PROCEEDED WITH THE ENG OVERHEAT PROC. WHEN THE LIGHT DID NOT GO OUT, CAPT STARTED A TURN BACK TO ALB AND PROCEEDED WITH THE ENG FIRE/SEVERE DAMAGE OR SEPARATION CHKLIST. AS WE WERE ABOUT TO START THE CHKLIST, THE OVERHEAT LIGHT WENT OUT. WE CONTINUED TO ALB, DECLARED AN EMER, AND LANDED UNEVENTFULLY WITH BOTH ENGS RUNNING. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT THE POSTFLT INSPECTION FOUND SOME GREASE ON THE LOOP CONNECTORS ON THE #1 ENG. THE PAX WERE PROTECTED ON ANOTHER FLT. AFTER MAINT WAS COMPLETED THE ACFT WAS REPOSITIONED ON A NON REVENUE FLT TO BOS, THE ORIGINAL DEST ARPT. THE AIRLINE SAID THAT THEY DID NOT WANT THE FIRST FLT AFTER CORRECTIVE MAINT TO BE CARRYING PAX. A MODIFIED FERRY FLT SO TO SPEAK. THE LOOP ON #2 ENG WAS IN PROPER WORKING ORDER. THERE WAS NO COMMON ANOMALY THAT CREATED THESE SEPARATE INDICATION PROBS.
