I am going to be installing a water temperature gauge for my '72 Chevelle. I have an Edelbrock Performer RPM intake and was wondering if there is a place on the intake that I could hook the sensor up to?

Thanks,
Ethan
 
Sort of a basic question but, why not put the temp sender in the cyl head like the factory did?
 
Dude if you ate going to be using this to monitor your engine temp then listen to everyone else and put it in your cylinder head. I would be more concerned with the temp of my heads than the intake temp. Use intake temp for fans. JMHO

Dude,
"everyone" did not say to install it in the head! So, let me ask you, do I need to drain any coolant to install in the cylinder head?

If you're not using an overflow tank on the radiator the coolant level is probably below either of those two locations. Wouldn't hurt to drain off a little more, particularly if you use the head as it's lower.

Factory location for the sensor was the head. In different years, different engines that wasn't always true. Manifold location will usually read 10-20 degrees below the head temp. If the you run a 180 thermostat then manifold should read real close to that. If it runs hotter than that then your cooling system isn't up to the job.

As I said the head temp should run 10-20 hotter if everything is normal. If the engine is running really lean or the timing is off then the head temp may be even hotter. Of course if it does run too hot using the head location is that because the engine isn't properly tuned or because the cooling system can't keep up? You can't tell without knowing the manifold temp.

On a properly tuned car either location will give you a good idea of what's going on. Put there are cases where neither location can tell the whole story.

Thank you.:thumbsup:

How much coolant that drains out is relative to how quickly you can remove the plug and put the sending unit in. If you're quick, no more than a few fluid ounces should get out.
