Auto Meter 2352 - Manual (Page 2)

Tools Required
Electric Drill
Drill Bits: 9/64", 3/8", 7/8" dias.
Open-End Wrenches: 7/16", 9/16", 3/8", 7/8"
Standard Screwdriver
Clean Rag
Thread Sealing Compound
NOTE: For Model 2351 & 2352 single gauges, refer
to hook-up instructions for your particular gauge.
Water Temperature
1. Drain coolant from cooled radiator into a container. Never drain
hot coolant! Save antifreeze to refill radiator after installation.
2. Drill a 7/8" dia. hole in firewall and route temperature sensing
bulb through mounted panel first and then through firewall
hole. Slit rubber grommet and position in firewall hole to hold
gauge tubing in place.
3. Using sealing compound on threads, insert and tighten
mounting nut in the 1/2" NPT port in engine. (Use 7/8" open-
end wrench). If port opening is not 1/2" NPT, use the 3/8"
adapter provided in kit. Insert temperature sensing bulb into
mounting nut and carefully thread the sealing nut into the
mounting nut. Be sure to hold the mounting nut securely
(with 7/8" open-end wrench) while tightening sealing nut
(with 5/8" open-end wrench). Check that tubing is free from
hazard of moving parts or hot engine components.
4. Refill radiator with coolant.
5. Secure gauge in mounted panel using non-insulated
mounting bracket.
Note: Whenever removing temp. sensing bulb, loosed sealing
nut but DO NOT allow mounting nut to rotate. Rotation may
break capillary tubing, thus voiding warranty.
Oil Pressure
1. Drill a 3/8" dia. hole in firewall. Install small rubber grommet in
firewall to insulate nylon tubing where it passes through
sheet metal.
2. Remove existing oil pressure sender (for computerized
vehicles, see warning on pg. 1). Install 1/8" NPT adapter
(with 7/16" open-end wrench) in this location using sealing
compound on pipe threads. If 1/4" NPT adapter is needed,
install it first instead ( with 9/16" open-end wrench). Be sure
to hold 1/4" NPT adapter while tightening 1/8" NPT adapter
firm (with 7/16" open-end wrench).
3. To help prevent leaks, be sure the end of nylon tubing is cut
cleanly and straight. Slide compression nut onto tubing with
threads toward end of tubing. Slide ferrule onto end of tubing,
leaving 3/16" between ferrule and end of tube. Insert end of
tubing into 1/8" NPT adapter. Apply pressure to maintain
constant bond between end of tubing and inside of adapter.
Slide ferrule into the adapter then compression nut. Tighten
compression nut (with 3/8" open-end wrench) while holding
1/8" NPT adapter firm (with 7/16" open-end wrench). To
make sure it is a snug fit, tug lightly on nylon tubing to make
sure it doesn't come out.
(Steps for installing this gauge continue on back cover.)
Voltmeter
1. Negative (-) battery cable should remain disconnected.
2. Fasten voltmeter in metal panel using insulated bracket, 2
lockwashers, and 2 #10 nuts.
3. Cut two lengths of 18-gauge wire. One wire is for connecting
gauge to fuse box, the other connects to good engine
ground. Strip insulation back 1/4" on one end of each wire.
Attach solder lug terminal and wire to positive (+) terminal on
back of gauge using proper lockwashers and #10 nut.
Connect other end of this wire to appropriate 12V source at
fuse box. Attach the ground wire to negative (-) terminal on
back of gauge and connect other end to good engine ground.
(Body frame bolt is a good engine ground.)
