960 Sudden Idle Surge: ECT Sensor Failure. Symptoms: sudden very high idle surges (2500-<br />

3000 RPMs) while sitting at idle and hot-start problems. See the fix.<br />

960 Engine Swap. [Inquiry] I just purchased a 1995 960 with a B6304 engine 150,000 miles.<br />

The block is leaking coolant and is clearly porous. I'd like to swap this engine with one from a<br />

1998 S90. Will this engine be a direct replacement or will it need modifications or not fit at all?<br />

[Jim Bowers] The S90 engine will be a direct bolt in <strong>for</strong> you. Just keep all the electronics and<br />

wiring harnesses from your present '95. 19'95 was the last year they made any "improvements"/<br />

changes to the engines they put in the 960 chassis. '96 got the OBD-II electronics but no other<br />

changes. The S/V90 got another external ambient temperature sensor <strong>for</strong> helping optimize<br />

control of the AC but no other engine related stuff. [Patrick McGinnis] I have pulled the 960<br />

motor three times and always with the transmission...up and out of the top of the hood opening.<br />

Transmission Problems:<br />

960 Automatic Transmission Questions. See the FAQ file <strong>for</strong> Auto Transmissions AW<br />

30/40 <strong>for</strong> more info. 960 cars have experienced a far higher rate of transmission troubles due<br />

to overheating.<br />

960 Won't Restart: PNP or Harness? [Inquiry] My '92 960 wagon will not start after short<br />

trips. The gear shifter will lock when placed into "park" and the car will not make a sound (other<br />

than the "click" when I turn over the ignition) when I attempt to re-start it. Usually, after sitting <strong>for</strong><br />

about an hour, the car will start normally. However, today it refused! Could this be the PNP<br />

switch? [Response: Etherman] Put the trans in PARK. Turn the key to #2. Step on the brake<br />

and attempt to shift out of Park. Does it happen? I think it will. If so, your PNP is working. In this<br />

case, look to a bad battery and/or voltage drop in the batt cables which may or may not exhibit<br />

signs of corrosion. Check the voltage drop on both cables. Greater than .40 volts is bad. $5.00<br />

says your positive cable needs to be spliced or replaced. [Quick Fix Tip] Cycle yourshifter back
