Sorry for the interruption, this plastic fitting...is it plastic on the 94 as well?

Yup. Look under your nosedrive at the passenger 'end' of the LIM. You'll see a black hose going from the water pump to the fitting.

That fitting is plastic. The replacement fitting from the dealer is metal. Replace it before it blows and cooks your motor or leaves you stranded.

Another thing to look for beckster..is where is the car wet...if it is wet under the radiator then most likely one of the plastic end caps on the radiator have developed a crack and is starting to seep slowly.

Tyipcally to identify a leak .... I see where on the car the drip is coming from and try to follow the path backwards.

Good work. Glad you found it. Coming out of the weep hole? That'* the first sign that the pump is failing.
