Your leak could be a clogged a/c drain tube.
Does this happen with a/c on or defroster?

Water is leaking from the floor vents what could be the proble?


Check your heater radiator. It is usually mounted behind/near the glove box areas on most cars. It is like a small version of the large radiator that is mounted on the front of your vehicle under the hood. Antifreeze and coolant (does it smell a little like antifreeze?) flows thru your front radiator, thru the block and hoses, and cycles thru the radiator for your heating system. If the radiator is leaking, often it cycles thru the vents on the interior.
Another possibility MIGHT be the AC system and condensation/AC coolant that is building up in/on the lines and transferring thru the vents.

Can I get a how-to on replacing the heater core in a 1997 Cadillac deville d'elegance?


It could be difficult, but I'll tell you some of the basic steps. Remove the 2 hoses going to the heater core, they are under the hood, more toward the passenger side back on the firewall, they attach to the heater core right there, pay attention to where each hose goes. You might need a special tool to remove those hoses due to the funny fitting they have on them. What I've done is cut them off and just use regular hose clamps on the hoses later. Now the fun part. Remove the plastic trim under the dash on the passenger's side, remove your glove box if you can to have better access. The heater core is inside a plastic cover, looks like a box, you need to remove the screws and take it apart to get to the heater core. Remove the heater core. Installation is reversed to removal. Do not put all the plastic pieces back till you are sure there is no leaks. Reattach your hoses and check your coolant level. Turn heat on and check for leaks, replace plastic trim and glove box. Done!!

There is a drain tube that clogs up. It is on the firewall under the hood on the passenger side. You have to access it from under the car. Use a stiff wire and clean it out. Sometimes you can clean it with a water hose and sprayer. Just don't put a lot of water in it. Spray a little, let it drain, Do this till you don't see any mold coming out. If it clears out and you still have water issues. Replace the heater core.

Smells like radiator fluid but its not running hot?


If you smell it in the cabin you probably have a leak in the heater core which is up under the dash. Look under the center portion of the dash on both sides and try pulling the carpet back in that area. Chances are you will find evidence of a small leak. Check all hoses for tightness that run along the firewall in the engine compartment as well.

I had a Fiesta once with a very similar problem. It turned out to be coming in around the seal of the windscreen. I solved it by lifting the seal with a spatula and thoroughly drying the glass and seal (on the outside), and then running silicone all around the edge of the glass, under the seal. (I used black but it wasn't visible anyway). This sorted it for me.

Renault Safrane Misfiring cylinders when hot.


Hi Steve
I'm Dave
First lets start with the missing coolant.
Check your oil dipstick, both cold and hot. If the oil shows any signs of a milkshaky consistency your head gasket is blown. If it is only a slight leak that started recently it may not have reached the milkshake stage yet so look carefully for any signs of foreign substance in the crankcase(oil resorvoir). If all is good there then look for signs of a leak on the lower weep hole of the water pump. You may need a telescopic mirror or to get under the car with a flashlight to see the small hole in between the two lower splines. Next check for leakage out of the coolant resorvoir jug. They sometimes crack or develop a slight leak that is hard to notice because it will accumulate in a spot not neccesarily inspected for coolant leaks. This all assumes that you've checked the length of your upper and lower rad hoses, the bypass hose and the two smaller heater hoses that go to the heater matrix(core) in the dash or firewall. Check for a leak anywhere along the radiator both front and back, near the draincock or along the walls separarting the tranny fluid cooling area from the coolant cooling area. Next you can check for a leak around the thermostat and the rad cap. All of these checks should be done with the engine at operating temperature except initial hose inspection which should be done twice once when hot. If these all prove dead ends you should suspect a heater core problem. Is the area on the floor mats under about where the two heater hoses enter the passenger compartment wet or do the windows fog up needing a/c to defog? If so your heater core is leaking. And finally if none of this helps you can check the frost plugs for leaks. They are hard to find. They are circular cutouts found on the engine case. There may be quite a few.
Post me with your results and we'll move on to your secondary problem. Oh yeah also check for a leak where your coolant temperature sensor enters the engine usually somewhere near the thermostat. Looks like a large screw with wires coming from it.
