Hi,
whilst people can and do use high power washing wands at auto washes to clean engines, you can cause problems with your electrics and air filter assemblies etc etc, Even if you use a home high pressure washer eg Karcher washer at home, it can cause problems.
Ensuring your engine is switched off and COLD - A safe method is to wrap plastic bags and tie them off around the alternator, the starter motor (if you can get to it), and potentially your air filter unit and intake (check your user manual if you don't know where these are. Make sure your oil and automatic transmission oil dip-sticks are pushed in all the way. Ensure your power steering and brake fluid reservoir caps are closed tightly.
Buy a can of commercial engine wash / degreaser (pressurized type in a can) or even mix up some bulk engine cleaning wash / degreaser and then apply as per the engine wash manufacturers instructions. Wait the appropriate time (15 mins or more usually) and then gently hose off your engine and engine-bay area with a garden hose trigger nozzle. I suggest you do this in an area where the grease and oil that gets washed off doesn't run into a storm drain or perhaps stain your driveway.
Stubborn stains and oil may need to be brushed and more engine wash re-applied. Once you have finished washing, remove all plastic bags, check the engine bay is all clear of rags, brushes etc and then start up your car. Upon starting your engine, you may get some squealing from the wet fan belts but that will soon pass as the belts and engine area dry off. Have fun!
Cheers,
Steve

If it is a 4.9L it is NOT a Northstar Engine, The 4.6L Engine WAS A Northstar.

Both Engines were available until 1996.

Idles high, running temperature is 225 degrees and have to push on accelerator to start

hi,

are you familiar with the northstar engine?
first generation northstars are notorious for this kind of thing..
the engine is prone for metal fatigue/ warping of the heads, and stripped out head bolts, do you have documentation and service history for it?
these engines need a good mechanic to inspect and replace head bolts which strip out and need fixing. I will post a link at the bottom
once the engine is repaired correctly it should last a good long time
have it fixed correctly. I think someone has turned up the idle knob in an attempt to get the coolant flowing quicker to keep it cool.
its worth repairing if you have the money..
