The switch is actually referred to as a thermo-time-switch. It has a bimetal type switch and a small heating element in it. When the switch goes above a certain temperature it opens up. It is heated both by the engine and by the heating element. After you apply power, it will heat up and then shut off. The colder the engine is, the longer it will take to shut off. The delay time can be as high as a dozen or so seconds. If the engine is warm, the switch will be off and stay off. The switch turns on the cold start valve (the fifth injector) and the goal is to turn it on when you first turn the key to "start" and then turn it off shortly thereafter. Thus the connection to the starter solenoid. If the car doesn't start on the first attempt, the second attempt will give little or no cold-start valve action, as the thermo time switch was already heated on the first attempt. |

Thank you genteman for your profesional answers
great help study the books but got confused has been bogging me for years to find out now I got it. hope to restore the car because it gave me 10 years service and I know wat I got I buy another how knows wat problems I buy in this electronic gismos age car world .......OOOO the good old times of simple carburateurs and chokes en ignition curse be on the new cars only the dealers get rich liltle mechanic is out of bussines. or screws the customer because he don't know what he is doing thank again for your time and help. moony.

Does it have a heating element in it? I was thinking that the thermo switch would only open the circuit when the coolant got warm enough. So when the coolant was cold the circuit would be closed and would allow the cold start valve to function. This switch was/is only heated by the coolant thus if the engine did not start during the first attempt, the cold start could continue to operate during the next attempts also. These sites agree with you so now I believe that it DOES have a heating element in it! http://www.mirafiori.com/~thad/fi/thermot.html http://www.international-auto.com/in...m?fa=ad&aid=15 http://www.ffp-motorsport.com/glossary/thermo.php As I understand that heating element will help to lessen an engine full of gas if it does not start after a few attempts! I am constantly learning more and more each day. Thanks Randolph! ;-) later, dave Reminder........ Before you criticize someone, you should walk a mile in their shoes. That way, when you criticize them, you are a mile away from them, and you have their shoes. Frieda Norris |

and seldom used how can I prevent rust and condence from acumilating in the tank. should I coat it with some oil.? Thanks Moony. |
