SOURCE: tcc solenoid code

I don,t reccommend doing this your self as the k-frame will need dropped and the trans case will need split to access the solenoid also when I have to do this I will not do it on the ground I use a lift or I dont do it.

if there is an access plate you can remove then yes. but generally you have to drop the tank to get to it

first disconnect the battery then check how the serpentine belt is lined up so u can take it off and put back on. Then the pump should be on the side of the motor with 9or12 bolts there could be more! after taking out take razorblad and skrap the old gasket clean wipe of then put new gasket and pump back on dont over tighten the screws cuase the pump my be aluminum.

SOURCE: need diagram of engine to replace fuel filter on

The fuel filter is located inside the frame rail, just ahead of the passenger-side wheelwell opening. It has a threaded fitting on the forward end, and a quick-release clip on the back hose attachment.
Caution! The fuel is under pressure. Wrap a rag around the quick-release fitting as you release it, to catch any spray. or first relieve the pressure at the test port on the injector fuel rail (under the plastic engine cover), again using a rag to catch the fuel spray. Wear safety glasses, and only do this when the car is completely cooled off. You WILL spill some fuel while doing this, so have a catch container, and/or spread oil-dry/cat litter on the ground under the filter area. After changing the filter, turn the ignition "on", which powers up the fuel pump, but do not start the car. Now check for leaks at the filter, and at the test port, if you used it to bleed off fuel pressure. If everything is dry, you are OK.

SOURCE: no heat in 2003 buick lesabre but engine overheating

The first thing you need to do is check the cooling system coolant level. If it is low or empty, there is not sufficient coolant to cool the engine or to transfer through the heater core to supply the cabin with heat. Fill it up and check for leaks. Once leaks have been repaired, change the thermostat, engine oil and oil filter. If it is full, you may need to change the coolant due to its age, as well as the thermostat, engine oil and oil filter. The reason for the oil change is due to the thermal breakdown of the oil in overheating conditions. Also inspect the water pump to ensure it is being driven by the belt. You may also have air in the cooling system that is causing all your problems. Generally only happens when the cooling system is improperly filled. Make sure you add the correct mixture of coolant and water. Incorrect ratios will cause you similar problems.Coolant protects the cooling system and the water dissipates the heat.
