THE COOLING SYSTEM
These tricks are of importance if you find that your Hunter is overheating.:
Pertinent with HE hunters.. the earlier models had the bypass in the valve at the heater.
Use this simple check to see if the bypass is blocked... Disconnect the heater hoses, and replace a short piece of heater hose between the two heater hose outlets., ensuring the hose is not kinked. if the engine runs cooler, there is your problem. if there is NO difference, see below.
Check that the BYPASS in the cast alloy heater hose fitting on the firewall is NOT BLOCKED.. The hex headed thread needs to be removed to inspect, however, care needs to be taken so as not to damage the fitting. If the fitting shows signs of being corroded, it is best to replace it so that problems do not occur later. When the heater valve is shut, water needs to be able to flow freely via the bypass so as to complete the circulation throughout the cooling system. This has caught quite a number of Hunter owners out.
Check the heat sinking capabilities of your radiator!! If by carefully using your fingernail, press lightly on the filaments between the cores.. if the filaments disintegrate or are very weak... It would be advisable to re-core or replace the radiator.
ALWAYS use approved COOLANT in the cooling system, as this is the best way to minimise corrosion. If the engine is pulled out of the engine bay, remove and replace the welsh plugs, paying particular attention to the rear plugs. Invariably, corrosion, rust etc does build up around number 4 and to a lesser degree, 3 cylinder. The "gunk" is so abundant that stops the water jacket from being effective. I have given the sizes of the welsh plugs, because I could never find them in any of my workshop manuals
WELSH PLUG SIZES and QUANTITY
2 1 1/2 inch
3 1 3/8 inch
Internal rear vision mirror vibrating? the rubber "damper" maybe perished. If so, cut off approx.1cm vacuum hose and replace the perished rubber with this.
Is the plastic clip that is used to secure the metal rod that holds the bonnet up broken?...Easy.. get a 6mm stainless clip from a hardware store and affix it the the body, using the original location of the the plastic clip
FITTING VENTED FRONT DISK BRAKES AND CALIPERS
Ford makes a vented disk and caliper configuration which is a direct bolt on to the Hunter. I have vented disks on one of my 660's.. Still trying to find out exactly what model Ford Capri they are from.
FRONT SUSPENSION STABILISER
If one of these can be affixed to the tops of the strut turrets, immense improvements are gained in road handling. I am trying to source a business that makes (or can make) these.
TROUBLE STARTING your HUNTER?
(ALWAYS DISCONNECT BATTERY BEFORE WORKING on ELECTRICS)
Check to see if there is a Wire wound resistor in series on the ignition wire to the (-) terminal on the coil.
If not, source one from a wrecker from any Japanese car, making sure you grab the wire that goes from the resistor to the coil. Mount it securely very close to your
coil and put the original ignition wire (White/red trace) on one side of the resistor, and the wire on the other side of the resistor to the (-) terminal on the coil.
This helps maintain a constant voltage into the coil, ensuring your spark is more "lively". Particularly in COLD weather.
I also suggest the starter motor <--> solenoid cable be replaced with a larger diameter cable to increase current flow.
MAKE SURE IT CANNOT COME INTO CONTACT WITH THE EXHAUST!!!
Replace any CONDENSERS (capacitors) at the same time, as over time, they do become "leaky". These minimize and bypass static discharge etc.
EG.. if there is noise from the ignition system heard on your radio, time to replace condensers.. Obviously suppressor plug leads minimize noise generated also.
FITTING A MORE RESPONSIVE DISTRIBUTOR TO YOUR HUNTER
Well worth the time and effort needed, as it makes the Hunter perform like a different car!
The distributor is replaced with a 1984 NISSAN BLUEBIRD series II electronic dizzy. These are available for around $100 second hand. Unfortunately, the base of the Nissan dizzy needs to be machined so that it becomes adaptable to the standard lucas dizzy base. This can be arranged at a cost.
It seems that the FUSE holder is a source of problems. Lights may flicker etc. I have found that by disconnecting the battery, and unscrewing the holder, carefully remover a matching pair of fuse holders from the plastic holder, and using steel wool on the fuse clasps, remove the corrosion that has built up over time. Re-insert, and do the next pair and so on. What I did was the totally remove all the clasps, and soaked them in vinegar, But the preceding method is also satisfactory.
Under the dash, there are TWO cable joiners.. A white plastic one and a black plastic one. Check these very carefully for signs of getting hot.. eg melted plastic. If there is signs of melting, snip the matching wires as close to the connectors as possible, and put new insulated (mated) connectors on the wire ends. and re join the wire which is now external from the original plastic connector. Melting of the plastic is caused by resistance in the original connector, due to corrosion over time.
Make sure the nut on the accelerator linkage is tight.
Use ENGINE OIL in the damper chamber,(in the area underneath the black plastic nut and attachment on top of the carby) ensuring that there is ALWAYS oil present.
1725CC with 5 main bearing crankshaft
Manual gearbox, carby dampers and engine use SAE 30W oil.
Every 4,000 miles, a few drops of engine oil should be put into the distributor cam, governor weights
