I'm pretty sure a quick call to your local Buick dealer parts man will get the answer. He'll have the parts database to hand. It looks like you know the answer already?

SOURCE: Pump Priming Problems.

you should try to pack the gears and pump cavity with petroleum jelly which will prime the pump and the oil will then displace the jelly. If you use any other kind of grease, the oil will not be able to displace it so make sure you only use petroleum jelly. This is the stuff used in the medical field but works great for this purpose too. Let me know how it goes and whether you have any further questions. Thanks and good luck

Oil leak, where could it be

the most common oil leak on the V6 is the oil pump drive gear, it is at the back of the engine under the throttle body, it is were if the engine had a distributor were you would look for the distributor, there is an o-ring on the gear housing that starts to leak and can make a very big leak because the housing is under direct oil pump pressure.

95 Buick Skylark 2.3 L 4cl There is a metal rod that goes into the thermostat housing. I am not sure what it is but it is leaking out of the connection. Is there some sort gasket that fits this...

The plastic housing on the driver side top of the engine that bolts to the head is the water outlet housing. The thermostat is under the car where the metal cooling pipe bolts to the water pump housing.

The metal tube that goes into the housing has an o-ring that seals it into the housing. The tube is held in place with a couple of bolts. Remove them and remove the tube. There should be signs of an o-ring on the tube. Sometimes you have to replace the housing in order to get them to seal up

Follow the top rad hose to the engine, where it connects that's the thermostat housing.

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.
