Follow the bottom radiator hose to where it connects to the engine. where it connects is the thermostat housing which is secured by 2, 10mm headed bolts. remove the 2 bolts and the thermostat and seal are behind it. replace the thermostat and seal, secure housing with the 2 bolts, fill with coolant, and you are done it is a very quick and easy job probably easiest from under the vehicle

Where is the thermostat on 1999 2500 v8 savanna


if you follow the hoses coming off the radiator one of them should go to your water pump and the other should go to your thermostat housing the thermostat should be under the housing. the thermostat housing is usually on the coolant return hose on the engine.

GMC 2005 Savanna, running lights will not shut off even when the van is turned off. Switch was replaced but the lights are still on.


Interesting that this same problem has started with my 2005 GMC Savana.....they turn on by themselves and won't turn off.

Where is the ac lowside port located on a 2005 gmc savanna van


The low side port of the 2005 GMC savanna Van is located on the low pressure side of the compressor.

This is found by locating the compressor driven by a belt that has a clutch that engages and disengages as the a/c cycles.

The low pressure piping is always in the larger diameter piping, and the high pressure side is always contained in the smaller diameter piping.

Therefore, follow the thick pipes from the compressor up to the accumulator, which looks like a large can of soup. On the accumulator receiver/drier is a port that connects to the tube that is connected to the can of r134a freon refrigerant.

Simply quick connect the tube to the low side port, which is located on the 'thick' tubing or on the accumulator and then fill until the low side pressure is 25 psi to 45 psi while the compressor is running.

When the car is off and the compressor is not running, the pressure should be 75 psi to 100 psi on a hot day.

Hopefully the system doesn't have a leak slow or fast in it.

PERHAPS THE FUEL INJECTORS ARE CLOGGED. TRY USING A BRAND NAME INJECTOR CLEANER AND FUEL CONDITIONER SUCH AS LUCAS OR I HAVE HEARD OF OTHERS THAT WORK WELL TOO. GIVE EM ABOUT A TANK OR SO TO WORK. I HOPE THIS HELPS. THANKS FOR USING FIX-YA
