The hose is on the side of the gas cap and it runs down to the bottom of the quarter panel. When I filled the gas tank up, gas comes out of this hose. We just had the fuel pump replaced. Its not leaking...


There are normally two hose lines from the fuel filler that run to the tank. The larger one carries the fuel from the nozzle to the tank. The smaller one is a vent hose that allows vapors to leave the top of the tank while filling. These vapors come back to the nozzle area and can be vented and/or collected by the nozzle depending upon air pollution standards in your area. If your second hose is running to the bottom of the quarter panel, it is probably the vent hose that may not have been reconnected at the top of the tank when the fuel pump was replaced. The fuel running down there is from kickback fuel at the time the pump shuts off. The real problem is that the vent line is open on top of the tank and when the tank is full, that can allow vapors and fuel to escape out of there and it could contact hot exhaust areas - a major fire or explosion hazard. Have this inspected and repaired IMMEDIATELY.

Look on the back of the engine for antifreeze-either by number 1-2 cylinder or back by the brake booster. It is a know problem with Saturn engines, leaking by the rear intake. Check under the surge tank, they crack and leak too-check the bottom of the water pump for leaks, it has a weep hole that, if the seal inside is broken, will leak. you need to look for symptoms and evidence of leaks-if there is no obvious leaks from hoses, or outside the engine anywhere, it may be a head gasket-check your oil for a milky texture, or greyish color. check the bottom of the surge tank for oily residue, and look for smoke coming from the tailpipe.

How to remove radiator cover to add antifreeze to radiator


Your vehicle is equipped with a surge tank. There is no opening in the radiator itself. To check or add coolant (antifreeze) to your cooling system, screw the cap off of the surge tank.

CAUTION: Do this only when the engine is cool.

This is covered on page 5-26 of the 2004 GMC Yukon Owners Manual.

I HAVE A 1998 CADILLAC DEVILLE AND NEED TO REPLACE A HEATER CORE TO RADIATOR MOLDED PIPE. HOW DO I DO IT MYSELF? CAN IT BE MODIFIED?


Modification done by inserting generic T fitting into 3 way junction (Heater Core, Water pump, Surge tank) and using heater hose instead of pipe. Bye the way; the return pipe from the surge tank was not leaking so I did not bother to replace that pipe. I am watching the hose to make sure that pressurization swelling does not cause chaffing of the hose. The original replacement pipe was $80 and this modification is a fraction of that cost. The labor savings is significantly more important & valuable since this pipe requires the engine to be dropped (cradle installation) in order to remove and reroute the pipes from the firewall side of the Northstar V-8. There are two hard to reach attachments on the block that make it a maintenance nightmare. The resultant elevation of the hose to the surge tank and back does not inhibit surge tank functioning, at least not at this writing. I am keeping a close eye on everything. Experimental, but very doable fix.
