Can't find where to fill up the water for radaiator

Assume blown head gasket. That's nearly the only thing that will get water into the oil.

It has a pressure cap on the white plastic reservoir where you fill the coolant. It is not on the radiator.

sounds like you have a very big problem, it could be anything from a blown head gasket to a cracked block, any way very costly

1st you need to make sure no air in your system open you radaiator cap and your heater to max and see if air bubles or circulation is going on fill up accordingly otherwise you have blockage in your system or water pump if no circulation ////make sure no bubles all bubles should be gone////look for coolant circulation in your radiator make sure your thermostat is not defective or placed in the right position.

The cooling temperture send unit is send out of range data to the computer (ECU).

The corrective is to buy a coolant sending unit and replace it.

The unit is withing 6 inches from the thermostat housing.


Since your car is a 2002 and probably has around 80,000 miles on the odometer so it's a good time to all of the following on the same time.


temp. sending unit / clean the contacts

drop bottom coolant has and flush radaiator

change 195 F thermostat and gasket + seal with black RTV.

Fill 50/50 mix coolant. /// if you live in aub-zero temp area then read the chart on the bottle for the recommended mix


Please rate my answer if it's helpful to you.

1. Drain the cooling system. Refer to Draining and Filling Cooling System (LS4 Static Fill) Draining and Filling Cooling System (LZE, LZ4, LZ9 Static Fill) Draining and Filling Cooling System (9C1, 9C3 Static Fill) Draining and Filling Cooling System (LS4 GE 47716 Fill) Draining and Filling Cooling System (LZE, LZ4, LZ9, 9C1, 9C3 GE 4771 Fill).
2. Loosen the water pump pulley bolts.
3. Remove the drive belt.
4. Remove the water pump pulley bolts and pulley.
5. Remove the water pump bolts.
6. Remove the water pump and gasket.
7. Clean the water pump mating surfaces
   1. Position a NEW water pump gasket and the water pump to the engine front cover. Notice: Refer to Fastener Notice.
   2. Install the water pump bolts. Tighten the bolts to 10 Nm (89 inch lbs.) .

1. Install the water pump pulley and bolts.
2. Install the drive belt.
3. Tighten the water pump pulley bolts. Tighten the bolts to 25 Nm (18 ft. lbs.) .
4. Fill the cooling system. Refer to Draining and Filling Cooling System (LS4 Static Fill) Draining and Filling Cooling System (LZE, LZ4, LZ9 Static Fill) Draining and Filling Cooling System (9C1, 9C3 Static Fill) Draining and Filling Cooling System (LS4 GE 47716 Fill) Draining and Filling Cooling System (LZE, LZ4, LZ9, 9C1, 9C3 GE 4771 Fill).
5. Inspect for leaks.

Hope this helps

follow the big hose ontop of the radaiator to where it goes into the engine. The thermostat will be under the spout the hose is clamped to

The drain valve is open. it is a "Tee" that can be turned by hand. It is on the "back side" at the bottom of the radiator sticking out towards the back.
Do not over-tighten (don't use pliers to tighten)

Not likely that the valve is missing. Look at the old radiator.

Hi have a pressure test done on the cylinder head to rule out a head gasket failure, also check the water pump, and last make sure the coolant system has been bled properly,

Hope this helps
