Huge problem here.

I once was able to get the one year only 1964 Chevelle Super Sport V8 water temperature sensor from NAPA. They no longer show the part in their catalog.

For those that know, the 1964 temp sensor is a lower ohm unit than the 1965 up.

I have tried a "65 up sensor and the result is the gauge for my "64 shows 85% to the hot side or next to the red line. The exact same problem with my prior "64 ss. I finally found a true "64 SS sender and that solved that problem. Here I am again with a new car and looking again.

If anyone can provide me with someones part number for a 1964 Chevelle SS 283 V8 car, it would be greatly appreciated. To be sure, the part number will be different for a 1965. I have been often fooled by the parts stores trying to sell me a "65 unit, Their catalog shows the years 64 & 65 as the same part. I KNOW BETTER.

I appreciate your help. Larry

Hello,

I have a 65 Elk with a 283. I purchased a replacement temp sensor at Kragen Auto last week installed it, and the idiot light lit up as soon as the engine warmed up. It has been doing this all week. Went back to Kragen today and explained the situation. The saleswoman bailed from the computer and checked her cross reference books. She discovered that the original purchase had a lower switch temp (~205-220 degrees). BWD part # WT352 had a switch temp of ~220-235. It works fine. I noticed in her manual that there were multiple sensors with different temp ranges that are designed to work with gauges. Maybe try a parts store and reference the BWD brand. Hope this helps.

The reason you are having a problem is not because of the 65 being different. As the matter of fact, just the contrary. ALL Chevy factory gauge sending units from 1957-1967 are the same, GM P/N 1513321. The problem is that the aftermarket suppliers and even GM serviced the things about a dozen different times in the 80's and 90's changing the specific resistance a little bit each time. After several services, the difference between what was originally correct and what was "now" available was light-years. You hook the newer unit into you 64 or 65 car and the gauge reads 15-20 degrees too hot. There are 2 alternatives: 1. step up and buy a "real" NOS 1513321 which will set you back 100-200 bucks, or 2. get a repro from one of our dealers as we now have made the proper piece with the correct resistance and configuration.

I gave up on finding a replacement some time ago, but just now saw your post. Thanks

You mention to buy one of "OUR" parts to solve the problem. More info please

Lectric Limited (http://www.lectriclimited.com) has the correct temperature sending unit. P/N 1513321

Check your email Larry as I sent all the info to your email as per your request.

I forgot to mention and assumed that all knew that a SS Super Sport car had gauges, not idiot lights.

I usually get the cheaper sender for the gauge and it will usually read too hot. I just add a resister in line, normally a 40 ohm is about right. I try to have it so it's about in the middle of the gauge when it is 180 degrees.

I appreciate it .. Larry
