SOURCE: coolant leak 1998 buick external

it sounds like the water pump may be leaking beacuse when runnung the seal is lubricated and may not be leaking at that time but when left over night the seal in the water pump contract and starts to leak. check for stains and leaks with a mirror before starting in the morning i think you will find that it is leaking. don't worry they are not bad to change. good luck

SOURCE: wife,s 97 buick skylark, 2.4 L., leaking water. need help!!!

I had the same problem a month ago. I thought it was the thermostat, which sits inside the lower water feed tube that runs from the radiator, under the car and up between the engine and trans axle to the thermostat housing and water-inlet housing attached to the water pump. I replaced it and it kept leaking. So I got under the car with a mirror and a light and found that it was leaking from a weep hole in the water pump. This happens when the water pump seal is bad. to replace the water pump you nearly have to take apart the back of the engine and the timing chain cover. The waterpump is mounted at the bottom of the back of the engine and is turned by the timimng chain. It took me two days to fix, and it was not easy. There are a couple of sites that have info, which helped me. It's about a $600 - $900 job if you take it to a repair shop.

SOURCE: Water(not anti freeze) is entering the front pass

Your air conditioner evaporator condensate drain is blocked.
The condensate draintube should carry this water out through the floorpan to the ground.
Look for a kinked or blocked drain tube from under the A/C evap housing.

SOURCE: MY 1996 buick skylark olympic edition leaks water

Taste the water and if it is sweet it is coolant leaking from the heater core. If it does not taste sweet it is a leak somewhere else. What you suspect is very possible. Start by making sure the drain hose is clear an not clogged. Then check the window gasket. A water hose left running on the window slightly will tell you where the leak is coming from.

Hello: Check the oil pressure sending unit for leaking. That could be the reason for the delay in the light going out and also the leakage. If oil has gotten on the serpentine belt replace it also. The sending unit will be near the oil filter assembly on the lower front of the engine.

Hi i have a 1994 dodge caravan it is leaking oil can this be fix im worry that we would have to save money for a van for my kids thanks


The Chrysler minivan products all had leaking problems. I have had 5 or 6 different Dodge or Plymouth minivans from 88 to 99. How bad is it. The most common thing is Valve cover leaks. Front and rear seals in the engine leak as well as the oil pan gasket. If its leaking a little bit at a time open the hood and look at the front and rear of the engine. Do you see grease and oil that has gone down the sides of the engine? Do you see a lot of grease on the engine with some clean streaks going through it. You may be able to see where its leaking from. If you know someone that knows what their doing have them change the leaky gasket/s. If not you can probably have it repaired for less than buying another van unless other things are seriously wrong with the van.
Hope this helps... Dale

My 1996 Toyota Camry is leaking oil in little spots on the ground when its parked, where could it be leaking from and how can i fix it?


You cannot repair the leak until you determine where it is leaking. More than likely it is leaking from the oil filter, oil pressure sending unit, or valve cover gasket. Check around the oil filter for a leaks and if you see oil on the filter then replace it. Check the oil pressure sending unit and if it is leaking replace it. Wipe all the oil off the bottom of the engine and any other place you see oil. Now place newspapers on the floor under the car and then start the engine and let it run for about 10 minutes and then shut down. Wait overnight and you can see where the leak is coming from.

Oil leak. Burning oil and leaving spots on the ground. Bad burning smell form the oil. Cant see any source from below.


If this is one of the front wheel drive v-8 models, there is a problem with the rear engine seals on some years. The seals open when the engine is hot and allow oil to drip. As the engine cools, the seals rejoin so the leak hides. Sometimes, all it takes is to retorque the existing sealing surfaces.
It may also be valve cover gaskets. The fan and motion of the car will cause these to run the dripping oil along to the rear of the motor like a rain gutter, then onto the exhaust and ground.

My transmission leaks what should i replace


There are at least 5 places on the Automatic transmission that can over time, and mileage develope fluid leaks. Front converter seal at the front of the transmission,pan gasket in the center,dipstick tube o ring at the center on one side ,speed sensor o ring,and the tail shaft seal at the rear,of the transmission.
Place a flat piece or huge card board,under the engine and transmission,after driving you will see where the fluid,red in color is dripping. Its easier to spot exactly where the leak is comming if you can look under the car,while it is running, The easiest leak is the pan gasket,the dipstick tube, and the speed sensor,then the rear housing tail shaft bushing and seal.
If the front seal(converter seal) is leaking the transmission will need removed,and the seal,and maybe even the front pump bushing Replaced,it would be a good idea to replace the bushing esp if it has high mileage,80,000 or 100,000 miles of use.Change the fluid and the filter,while repareing the leak or leaks.Is a good idea.

Oil leak


Does the oil have a strong smell? It sounds like it is your front differential and it may be that the lube center overfilled it during their routine. Take it back and see. If they have see if they can take a bit out.
