I found a coolant leak above the the oil filter housing area. Im trying to find the part on alldata but I don't know its part name. Anyone have any info on it? sensor, switch, sender,?
Thanks for your help.

Do you have a water cooled alternator ?
I think the '99 does have a water cooled alternator.
The oil pressure switch would not leak coolant. Neither would the CKP sensors.

The '99 eldo doesn't have a water cooled alt. my mechanic says there is a gasket between the oil filter housing and
the engine block that has been known to spring a leak of coolant. It's going up on the lift after lunch to inspect.
He knows sometimes I fix it myself, meaning he won't mislead me.
Also in regards to alldata, I have multiple year subscription, however I can not find a view of the forward side of the
engine or just the oil filter area, any suggestions? I am going to google N* engine view next. Is there a sticky that
give a view or two? thanks Ed
Your mechanic is misinformed. The seal between the oil filter adapter and the block (lower case half) is an oil seal. I have removed mine to replace the CKP sensors and there was no coolant loss. Coolant is above the halfcase seal.

There is no coolant involved in the oil filter adapter, the 2 O-rings or the 2 retainer bolts.
Been there, done that - several times on several cars.
(IF the engine has V03 - HD cooling with an engine oil cooler, the oil lines run to a tank cooler in the passenger end radiator tank)
