Dashboard lights not working

Hello. Here a non-photo diagram. Hope this helps!!!

The thermostat is located on the side of the water pump, the water pump is located just above the a/c compressor, the thermostat is fed coolant from the radiators lower radiator hose.
Thermostat :
1. drain coolant and tighten drain plug ( easier method : remove radiator cap, get big drain pan, place drain pan under lower radiator hose to radiator connection, remove clamp, slowly remove hose, allow coolant to drain into pan, now is a good time to remove radiator hose and clamp from thermostat housing )
2. remove thermostat cover / cap ( easiest to get at this when front of car is supported by jack stands and right hand side lower cover is removed ).
3. thermostat cap is held on by 3 bolts / remove thermostat.

You will notice that the thermostat's air bleed hole is pointing up and lines up with notch in water pump housing,,

ATTENTION :failure to install new thermostat in the correct location will cause engine to overheat.

1. install new thermostat to water pump, make sure air bleed hole lines up with notch, install and tighten bolts, install a new lower radiator hose, fill cooling system.

thermostat # 17670-77E00
lower radiator hose #17854-65G20
hose clamp #09401-36403
upper radiator hose # 17852-65G20

Instructions

1. • Drain the cooling system. Draining the cooling system will prevent toxic engine coolant from leaking into the passenger cabin of the vehicle during removal of the heater core. To drain the cooling system, simply disconnect the lower radiator hose from the radiator by loosening the hose clamp and pulling the hose off. Be sure to drain the fluid into a sealable container and dispose of the coolant at an appropriate disposal site.
   • 2Pull the dashboard six inches rearward. In order to do this, you must remove the following parts; the center dash bolt (located under the defroster vent cover), the bolts under the driver and passenger kick boards, the bolt connecting the dashboard to the radio mount, and the the bolt connecting the dashboard to the rear of the glove box. The locations of these bolts are immediately apparent upon looking under the dash. Once you have removed these bolts, you can pull the dashboard rearward and secure it.
     
   • 3Remove the heater core box. The heater core box is a black plastic box that surrounds the heater core. This part should be visible when looking down into the dashboard from the passenger side seat. Remove the two bolts on top holding it to the firewall and another on the bottom near the foot well. After removal of these bolts, the heater core and box are attached to the vehicle only by the coolant lines, which you can now disconnect by reaching into the box and pulling them off of the heater core (you may have to loosen the clamps first).
     
   • 4Install the new heater core. This is accomplished by applying steps 1 through 3 in reverse order; re-connect heater core coolant line, re-install heater core box (be sure to apply silicon sealant to the edges of the box, hermetically sealing it), replace the dashboard and install bolts, and re-fill the cooling system.

open the hood and inspect for leaks. if you smell it, theres a leak. check radiator hoses,caps on radiator and plastic overflow resevor . a flash light may help find a small leak as the hoses run into dark places. the place that installed the radiator may not have done a good job. the caps should be checked with cold engine and the hoses with hot engine. donot remove caps when HOT. good luck

Well I would start with the small things and work my way up. Make sure your radiator is topped off with the manufacturers recommended fluid and ensure there are no torn hoses or leaks. Next you might try purchasing a new thermostat. They are inexpensive and easily changed.

To Replace a Radiator check this procedure...

Tools:
1. Combination Wrench Set
2. Screwdriver
3. Flashlight
4. Cooling System Pressure Tester
5. Needle Nose Pliers
6. 3/8 in. Drive Ratchet
7. Socket Set

Supplies:
1. Coolant

Steps:
1 Open the hood and locate the vehicle’s radiator.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.

2 With the engine off and cold, remove the radiator cap.

3 Place a drain pan under the radiator. Remove the drain plug or remove the lower radiator hose to drain the cooling system.
o Tip: Twisting the hose or using a screwdriver may allow easier removal.
o Tip: Lifting the vehicle will give better access to the lower radiator hose.

4 Remove the upper radiator hose.

5 Remove the radiator fan shroud or remove the electric cooling fan assembly.
o Tip: Transmission cooler lines will need to be removed when replacing the radiator.

6 Remove the radiator.
o Tip: Some older metal radiators can be taken to radiator repair shops for repair.

7 Install the new or repaired radiator. Make sure it is aligned.

8 Install the lower radiator hose and clamp.
o Tip: Replace the hose and clamps if necessary.

9 Install the radiator fan shroud or electric cooling fan assembly.

10 Install the upper radiator hose and clamp.

11 Fill the radiator and radiator reservoir with a 50/50 mix of coolant and distilled water.

12 Install the radiator pressure tester and check for additional leaks.

13 Re-install the radiator cap and start the engine.

14 Monitor the engine temperature.
o Tip: DO NOT allow the engine to overheat.

15 Road test the vehicle, maintaining supervision over the temperature gauge.

16 Verify repair by inspecting for leaks or overheating.

Check this procedure to how to replace a water pump (DIY Complexity: Moderate / Time: 3.5 hours):

Parts:
1. Water Pump

Tools:
1. Screwdriver
2. Scraper
3. 3/8 in. Drive Ratchet
4. Cooling System Pressure Tester
5. Needle Nose Pliers
6. Socket Set
7. Radiator Hook Tool

Supplies:
1. Coolant
2. Silicone Sealant

Steps:
Step 1 With the engine off and cold, open the hood and locate the vehicle’s water pump.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.
o Tip: Before removing the radiator cap, squeeze the upper radiator hose to verify that the cooling system is not pressurized.

Step 2 Remove the radiator cap.

Step 3 Install cooling system pressure tester. Apply the pressure indicated on the radiator cap or in the owner’s manual.

Step 4 Inspect cooling system components for leaks.

Step 5 Place a drain pan under the radiator. Open drain valve or remove the lower radiator hose to drain cooling system.
o Tip: Depending on the vehicle, lifting the vehicle may be required to gain access to the lower radiator hose.

Step 6 Remove the drive belts or serpentine belt.

Step 7 Remove any hoses connected to water pump.

Step 8 Unbolt water pump from engine. Remove the water pump.

Step 9 Using a gasket scraper, clean the mating surface on the engine block.

Step 10 Install new water pump and new gasket. Tighten bolts to manufacturer’s specifications.
o Tip: You may want to use a light bead of silicone designed for water pumps.

Step 11 Re-install any hoses and belts that were removed.

Step 12 Re-install drain plug or lower radiator hose.
o Tip: Squeeze the radiator hose. If it feels soft you may want to replace the hose at this time. Always use new hose clamps.

Step 13 Refill radiator with a 50/50 mix of coolant and distilled water, then pressure test the cooling system and check for leaks.

Step 14 Fill overflow reservoir with same mixture.

Step 15 Leave the radiator cap off, start engine and let it idle. You should see the system“burping” bubbles of air. Refill the radiator to the top.
o Tip: Most air is expelled after a couple minutes of idling. Be cautious of potentially hot fluid overflowing.

Step 16 Install radiator cap.

Step 17 Road test vehicle, keep an eye on the engine temp gauge if vehicle runs hot, there still might be an air pocket in the cooling system. The cooling system should be topped off after vehicle has fully cooled down.

Good luck.

It is not the thermostat since it only overheat on stop n go situation. Most likely cause is a bad radiator fan. Turn on the AC and see if both the radiator, and the condenser fan works. They should both be working when the AC is turned on. Lets stick to this for now. Let me know what happened. I don't want to confuse you with too many possiblity.
