SYSTEM EXHAUST MANIFOLD
1. All exhaust manifold tube is manufactured to a standard diameter. All joint connections, on all sizes of
fittings, push fit into the relative tube and should be sealed using high temperature silicone sealant. No
locking bands are required.
2. Tube joints should be made as follows:-
Cut tube to length required, remove all burrs and wipe off any oil or grease with a clean rag. Apply a bead
(3mm) of high temperature silicone sealant around both the outer end of the fitting and the inner end of the
tube. Insert the fitting into the tube up to the raised bead around the fitting. (50mm) using a slight rotary
action to spread the sealant (Fig. 11).
NOTE: The sealant remains workable for approximately 5 minutes after application.
3. Finally, secure the joint by drilling 3 equally spaced holes (Ø5.5mm) through both the tube and fittings (one
hole to be at 12 o’clock to prevent possible leakage of condensate) and rivet the tube to the fittings Ø5 x 6
pop rivets.
