  1. Document ID# 158416 1998 Cadillac Seville Cooling System Description General Description The cooling system maintains proper engine temperature under all operating conditions. When the engine is cold, coolant in the radiator does not circulate, allowing for faster engine warm-up. The thermostat remains closed until the engine reaches the proper operating temperature. Once the engine reaches normal operating temperature, the thermostat opens, and the coolant circulates through the crossflow radiator in order to keep the engine from overheating. The cooling system includes the following components: A radiator A radiator surge tank and pressure cap 2 electric engine cooling fans A thermostat and housing A coolant pump All related hoses Cooling System Circulation In the Northstar cooling system, the coolant pump takes coolant from the radiator and passes the coolant through the thermostat on the inlet side of the coolant pump. The coolant enters the block at the rear of the engine from the water crossover, then the coolant is routed through the cylinder heads back to the water crossover. At this point the coolant has four possible routes: The radiator The heater core The throttle body heater circuit The generator cooling circuit
  2. Wiring diagram at: http://autolib.diakom.ru/CAR/Cadillac/1997/DeVille/SYSTEM%20WIRING%20DIAGRAMS/9078.pdf
  3. Here is a summary of info from FSM: Document ID# 380671 1999 Cadillac Seville   1 Raise the vehicle and support by the frame allowing the control arms to hang free. 2 Remove the wheel and tire. 3 Insert a drift punch or screwdriver into the caliper and rotor to prevent the rotor from turning. 4 Remove the wheel drive shaft nut. 5 Remove the caliper bolts and support caliper. 6 Remove the rotor. 7 Disconnect the front wheel speed sensor connector and unclip from the dust shield. 8 Remove the hub and bearing retaining bolts and dust shield. 9 Place the transmission in PARK. 10 Using J 28733-B separate hub and bearing from the drive axle   INSTALLATION Important Clean rust and foreign material from the knuckle mounting face, bore and chamfer to allow for proper seating of the bearing and knuckle. Reverse of removal,,,,, Install the hub and bearing bolts to 130 N·m (95 lb ft). Install the caliper and caliper bolts to 51 N·m (38 lb ft). Tighten the wheel nuts to 140 N·m (100 lb ft).
  4. For your info a post that includes FSM procedure for 2002 crossover here. Both pumps should fit. Go to ACDelco and input part numbers for application. Input numbers with a hyphen - ex 251660 as 251-660. ACDelco has several parts lines described here. I can't explain differences - if any - especially with big price differences between lines. I understand that with care the EGR tube can be reused. No 7 is it.
  5. How to pull codes at: http://myweb.accessus.net/~090/resources-cad.html#om
  6. Do an advanced forum search of titles only for "crankshaft position sensor" - all the info needed - one of hits includes a picture.
  7. What's happening with coolant level in resevoir?
  8. Do a forum search for vats - should provide all you need. No need to get fancy - all you need is the correct resistor(s) in the circuit.
  9. The top appears to be part of the replacement cable. Look at instroctions at sellers site - HERE.
  10. Owners Manual is specific on entering feature programming - are you following it? Are you sure your car is equipped to do what you are trying to do? A detailed description what you are doing to turn it on could be helpful. More info could bring responses.
  11. Check for diagnostic codes - how to here. Look up their definition at the same site and post codes and definitions.
  12. The horn relay is not in the seat circuit. It is located in the relay center which is by the circuit breakers. The window and horn relays are both 30A so you could try the window relay in the horn socket. It appears that rockfangd means seats without memory function when referring to base seats.
  13. The horn and seats are on the same 30a circuit breaker - nothing else on it. There is a horn relay in the relay center. I have the electrical schematic but can't figure out how to post it.
  14. If battery is Delco heres some info: In past a date code number hot stamped on the top of the battery. Year (0-9) Month (A-M,skipping I). 8C = 1998, March Now I fnd: The warranty date code is located on the top label of the battery. The first character is either a P or S. The next two digits determine the month, the third digit is year and the fourth digit indicates the manufacturing plant. For example, P 094N means the battery was made in September 2004 in the New Brunswick factory.
  15. Do an advanced search for cabin in titles only - all the info you need.
  16. From FSM - no mention of backup light switch. Backup Lights Circuit Description Battery positive voltage (B+) is supplied at all times to the REVERSE relay coil through the rear fuse block. Battery positive voltage (B+) is supplied at all times from the rear fuse block PRK/REV Fuse to the REVERSE relay switch. The powertrain control module (PCM) sends a class 2 message to the rear integration module (RIM) indicating that the gear selector lever is in the REVERSE position. The dash integration module (DIM) sends a class 2 message that the ignition switch is in the ON position. When these conditions occur, the RIM grounds the REVERSE relay coil. The coil is energized, closing the switch contacts. This supplies battery positive voltage (B+) to the backup lamps. The backup lamps are both permanently grounded, so both backup lamps have power and ground, and then light.
  17. What is history of problem? What codes do you have - how to pull codes here. what
