HI I have a 91 eldorado biarritz 4.9, i had water pump failure and replaced and found water leak behind water pump coming out of what appears to be the water pump inlet gasket so i took the water pump back off and to get the front cover off to replace that gasket i need to get the damper pulley off. The chilton manual shows 4.5 to jack car up and lower r.s. engine cradle...4.9 shows to just pull the pulley...I have 4.9 with no cradle and no clearance to pull the damper pulley...do i need to lift the body from the frame?? and if so any thing i need to remove or disconnect?? and suggestions or answers would be greatly appreciated....
