If no drain plug on base of tank you can disconnect fuel line at engine and use an external electric fuel pump connected to fuel line to pump empty

Cars and trucks manufactured since the late 70's have anti-siphoning screens at the bottom of the fill tube to the tank. So, sorry to say, no you can't siphon this new gas. I can truly commiserate with you as it's happened more than once. I've just filled my tank and the vehicle bites the big one. The only way to get to that gas is to drop the tank.

SOURCE: Fuel Gauge Stuck on Full 98 Pontiac Montana

When gauge is pegged at full, usually means a bad ground. Check wires at fuel tank, wiggle around, maybe one came off. The bad news is it is hard to get to without removing the tank. Sometimes you can reach arm in and get to them. Also check body ground at read of van.

SOURCE: Can't fill the gas tank on 98 Toyota Camry

I have a 2000 camry that I just fixed today. there is a vent tube and valve on the carbon canister that is located just behind the gas tank and above the cross member. this vent tube will get plugged up by ( of all things ) spiders, dirt daubers, and I even had a mouse pack the tube with dog food. Just remove the tube and the valve from the canister and clean them out. You will now be able to fill your gas tank again.

What is the easiest way to remove the rear thermostat housing bolt from a 98 montana? Driving me nuts!

There is a YouTube video of this procedure. Put "1998 Montana thermostat replace" in browser and multiple sites come up. One of them is the YouTube video. Personally, I'd go to local parts store and get the Chilton?Haynes manual for your make/model and year. The instructions are easy to follow, and pictures are provided. Then you have the book for future reference for repairs.

DIRECTION FOR THERMOSTAT REPLACEMENT FOR A 1998 MONTANA

The exact location of the thermostat varies depending on the particular engine model on your Pontiac Montana. Although 2.0L turbo and non-turbo engines locate the thermostat on the upper section of the engine, other models may follow the lower radiator hose to a lower position on the engine, requiring the removal of one or more components for replacement. see below

  • Park your car in a safe place and open the hood.
  • 2Locate the thermostat housing by following the upper or lower radiator hose from the radiator towards the engine. The end of the hose should be connected to an aluminum or metal housing attached to the engine by two mounting bolts.
  • 3Remove the air cleaner duct assembly and the crossover exhaust pipe, if necessary, using a wrench and ratchet and socket.
  • 4Place a drain pan underneath the radiator drain valve. Open the valve and drain some of the coolant to empty the radiator hose; then close the valve.
  • 5Remove the radiator hose from the thermostat housing by disconnecting the clamp using a pair of rib joint pliers, Phillips screwdriver or ratchet and socket, depending on type of clamp used on your particular model; then remove the hose.
  • 6Remove the two thermostat housing bolts and lift the housing off the engine. Before removing the thermostat off the engine, pay careful attention to the position of the relief valve on the thermostat in relation to the mounting base on the engine, looking for any special marks. The new thermostat has to be mounted in this same exact position. Also, note that the thermostat spring has to point towards the engine once it is seated on the engine; then remove the thermostat and any gasket material if necessary.
Installation
  • 1Clean the thermostat housing and engine mounting surfaces from gasket material, if necessary, using a plastic scraper; also, clean the bolt threads of the thermostat housing bolts of sealer, if necessary, using a wire brush.
  • 2Apply a light coat of Room Temperature Vulcanizing (RTV) sealer to the new paper gasket if your particular model requires one; or install a new O-ring to the center of the thermostat; also, apply a light coat of RTV sealer to the threads of the thermostat housing mounting bolts.
  • 3Install the new thermostat on the engine mounting base in the same exact position as the old one; install the paper gasket if required and set the thermostat housing in place. Start the housing mounting bolts by hand and then tighten the bolts.
  • 4Connect the radiator hose to the thermostat housing; then install the crossover exhaust pipe and air cleaner and duct assembly, if necessary. Fill the radiator with new coolant, start the engine and let it reach operating temperature. Check for leaks and add more coolant to the reservoir to bring the level between the Add and Full Hot marks and turn off the engine.
  • 5Bleed the cooling system if the thermostat housing is provided with a valve screw on it. Once the engine reaches operating temperature, loosen the valve screw until coolant begins to leak through the screw; then tighten the screw again

Drain coolant at the radiator drain. Remove air intake hose and MAF sensor assembly. remove throttle cable bracket and disconnect cable linkage. Remove throttle body bolts and disconnect coolant hoses to throttle body. Loosen heater hose pipe and remove heater hose from rear of pipe. Remove radiator hose from thermostat housing. Remove top thermostat housing bolt. Loosen and almost remove lower thermostat bolt. You will need to slide your wrench and hand under the exhaust crossover pipe to gain access. Loosen the bolt until you can remove the thermostat housing, it should be slotted to clear the bolt. Replace the thermostat and reassemble. Bleed cooling system using the two bleed screws (one on thermostat housing and the other on the passenger side of the engine where the heater hose pipe comes out above the water pump.
