Stan, Be careful with this one. I just found out that even though my sender works fine, it won't go on if there is no coolant. After I (hopefully) blew my head gasket, fixed the leak and refilled the radiator it comes on like a charm. I highly recommend hooking up a real gauge. At least temporarily until you find out what the problem is. Without a gauge it will be hard to tell the effects of any change you make. Especially since your light isn't always on and the by the time that idiot light comes on you are in definite danger of overheating. If you want to check it, the sender is behind/under the a/c compressor. Easy to see, hard to reach. In the archives/repair section Dick B. or some other capable party explains how to check it. Good luck, Rob _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com
