REMOVAL & INSTALLATION


CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

  1. Note the radio security code and station presets.
  2. Disconnect the negative battery cable.
  3. Drain the engine coolant into a sealable container.
  4. Remove the fasteners from the thermostat housing, then remove the thermostat.

To install:
See Figures 1, 2, 3 and 4

Fig. Fig. 4: Always install the thermostat with the small pin at the top. The rubber thermostat seal is installed around the thermostat

  1. Install the thermostat using a new seal. If the thermostat has a small bleed hole, make sure the bleed hole is on the top.
  2. Apply an anti-seize compound to the threads of the fasteners.
  3. Reassemble in the reverse order of disassembly.
  4. Set the heater to the full hot position. Set the heater to the full hot position.
  5. On Odyssey models with 4-cylinder engines, locate the coolant bleed valve near the thermostat housing and open the valve 1 / 2 turn.
  6. Top off the cooling system and overflow reservoir with a 50/50 mixture of a recommended antifreeze and water solution, and bleed the system to remove any air pockets as necessary. Simultaneously squeeze the upper and lower radiator hoses to help push any captured air pockets out of the system.
  7. Inspect all coolant hoses and fittings to make sure they are properly installed and if previously opened, close the bleed valve.
  8. Connect the negative battery cable.
  9. Install the radiator cap loosely and start the engine. Allow the engine to run until the cooling fan has cycled two times, then turn the engine OFF and top off the cooling system as necessary.
  10. Install the radiator cap and inspect for leaks.
  11. Enter the radio security code.


WARNING The manufacturer does not recommend using a coolant concentration of greater than 60% antifreeze.
When mixing a 50/50 solution of antifreeze and water, using distilled water may help to keep the cooling system from building up mineral deposits and internal blockage.

I HAVE A 1998 DODGE CARAVAN AND i NEED TO REPLACE THE HEATER CORE WHAT ARE THE STEPS AND WHERE IS IT LOCATED?


It can be amessy job. The core has to be drained first by disconnecting the hoses at the firewall. You will most likely to remove the glove box and trim around the blower. It will involve alot of working from the ground under the lower dash i.f youre handy and can work without being messy it can be done. One note of advice if you spill coolant into your floorboards and it gets into the sound deadener pads the smell will be there a long long time it really stinks.

I have a Honda accord 2.4 exec on an 03 plate. The heated seat switch lights on bothe seats but neither get warm. Is there a relay that needs replacing? any help would be appreciated.


According to the factory wiring diagram for a 2002 Honda Odyssey, the seat heater switch hi/low indicator lights won't light up unless the seat heater relay is good. The seat heaters have thermostats and circuit breakers that limit power to the seat heaters under the following conditions:

Thermostats: On below 93F and off above 109F

Circuit breakers: On below 86F and off above 122F

The breakers operate in series with the thermostats and serve as backups to faulty thermostats.
