Pressure washing under hood probably isn't a good idea...lots of electrical connections etc. that hate water...especially high press. water that can get into places it shouldn't be.Originally Posted by nfpgasmask
Here's a pic with some red things indicating where to look...
See if you can trace the thing that the middle red thing is pointing to (that the upper radiator hose attaches to), back under the intake manifold where it attaches to the block...this valley under the intake is most likely where your leak is.
There are heater hoses, thermostat housing, etc. under there that could be the scource.
BTW, you'll need a flashlight...![]()
