Vanden Plas L6-4.0L (1990)
If erosion is confined to the non-critical area surrounding the coolant passage (Fig. 1 D), repair the cylinder head face to its original profile using locally
obtained epoxy plastic filler material, such as:
^
Loctite Weld
^
J-B Weld
^
Marine Tex
Finish the filler material with a hand file so that it is flush with the original cylinder head surface. Clear any filler material from the coolant passages and
bolt holes.
CAUTION:
Do not score or damage the original cylinder head surface.
NOTE:
Upon reassembly, use only phosphate free antifreeze/corrosion inhibitor (JAG 111) in the cooling system in a 50% concentration (specific gravity
1.079).
Warranty Policy:
Cylinder heads replaced on warranty must be returned to Jaguar Cars for inspection.
If a returned cylinder head is found to be in repairable condition (using criteria provided in this bulletin), the claim will be debited for the cylinder head
cost, less the cost to repair the original head.
