RADIATOR (1.6L, 2.3L HSC, 2.4L) - IDENTIFICATION AND SERVICE PROCEDURES FOR NYLON TANK RADIATORS
FORD 1981-84 ESCORT, EXP, TEMPO
LINCOLN-MERCURY 1981-84 LYNX, LN7, TOPAZ, MARK VII, CONTINENTAL
Three different types of radiator cores are currently used with nylon end tanks. They are a conventional copper/brass core, a mechanically assembled
aluminum core and a vacuum brazed aluminum core. If the aluminum core is mistaken as a copper/brass core, and if an incorrect service procedure is
attempted (such as the use of a torch and soft solder which will burn the epoxy on the air side of the header), the core may be permanently damaged.
It is the responsibility of the servicing dealer to advise the radiator service facility that the radiator has an aluminum core and that epoxy is used on the
air side of the header. Service procedures for nylon tank radiators are given in Section 27 of the respective vehicle shop manual. This information should
be made available by the servicing dealer to the radiator facility so that servicing is consistent with the recommended procedures.
The following list identifies nylon tank radiator core usage by vehicle and model year.

All of the preceding radiators have nylon tanks and can be identified as follows:
Figure 10
Mechanically Assembled Aluminum - available in both the standard and narrow width and can be identified by the round tubes. This radiator core has
epoxy on the air side of the header (Figure 10) and should be serviced only with epoxy as outlined in Section 27 of the 1984 Shop Manual E.
Copper/Brass - used only on Escort, Lynx, EXP & LN7 vehicles and can be identified by the steel side supports (Figure 10) which are attracted to a
magnet. This radiator core can be serviced using the conventional torch and soft solder method.
Vacuum Brazed Aluminum - similar in appearance to a copper/brass core but is all aluminum including the side supports. This radiator core has epoxy
on the air side of the header and should be serviced only with epoxy as outlined in Section 27 of the 1984 Shop Manual E.
