I am new the whole web forum thing. So I am not sure how to do this asking for help or finding answers on web. My car is a white 78 - 280 with 69,652 org.miles. I have had it over 2 years, but dont drive it much. My plan was to work on it (but also have a 72 chevelle that I also had plans for) and restore to it's formal glory. It is in great shape and when I do drive it it does get a lot of attention. This brings me to my situation: this weekend my timing belt on my daily driver (2000 nissan crewcab w/ 297,500 miles) finally snapped - it is in the shop. So, yesterday I charged the battery, washed and checked all fluids and I drove the Z to work. At lunch, after getting it inspected (it passed with flying colors) my RPM gauge stopped working... I can drive this back home since is seems to be driving fine- correct? And also is this something I can fix myself...I looked under the hood since I figure it is like an ole bicycle cable and it may of snapped. This brings up an old issue of my Temp gauge...Since I have not replaced the temp gauge sensor I got last summer online (cause I cant find where it is suposed to go) I thought it would be a good time to join a forum or club that has the same appreciation for these old cars. So to make a long story somewhat shorter... it is going to be 100º today, tomorrow and for the rest of the summer- I am going to need to drive this a few days straight and now my rpm gauge is stuck, the temp gauge not working... can I fix or should I just sell this project to someone that knows a bit more about this car? I love it, but it seem every time I take her out she comes home with battle scars. Thanks in advance. TXZ

Welcome to the club.

The tachometer is actually electrical in nature. The speedometer/odometer is the one which has a cable running to it. Having things break is simply the nature of old cars. I suspect the Chevelle is no different. Whether you should fix things or sell the car to someone else gets to the core of owning an old car and whether or not it's right for you. The things you've mentioned so far are fairly minor and the car is still drivable which puts you in better shape than a lot of people trying to fix up an old car.

The temperature sensor attaches into the thermostat housing. Follow the upper radiator hose from the radiator to the thermostat housing.

Thanks. I will leave work and go home and give it a go. I dont really want to let her go, it just seems like every time there is something else... I do appreciate your reply so now I feel better about driving back home. And for the temp, that is what I kinda what I did but maybe I got the wrong part since nothing looks the same... well I am off and hopefully running!
