Hello to all! we were on our way to a local car show in the cougar! cruzing down the highway and digging on the radio! To my surprise temp reads 220 not good! Come to find out it broke a belt! To find out the water pump bearing seized up!After a mirical of gettnig the car home without trailering! It now has the nickname HELZA! So the aluminum water pump is on its way! Sooo is the timing chain cover a big deal to change while im in there? and please dont tell me the oil pan has to come off for that! Any input would be great!and what type of gasket sealer works good?
