AC problem

[Dan12GT]

I can agree totally that the heat is the problem. I used to have similar problems with starter motors going out on an old car i had in high school. It too sat directly under the exhaust manifold. I would have to replace those damn things almost yearly. I am now very interested in doing some heat wrap myself. Any particular brand you'd recommend / where to get it?

I will post up some pics of mine when I finish. I used what I had left of the regulare Dei 1'' wrap tape. Silver in color. Now for the heatshield Im going to use DEI gold wrap. I have a 24'' by 24'' sheet with some leftover from building a heatshield for my dsm's alternator. IT was $70!! The best by far though. Its hard to reach the compressor and even harder to mount. I went to Lowes and bought some foil a long time ago it worked great for the alternator shield.

Honestly this would be a great product to market. I see tons of "AC out" threads all over google and it is scary.

Ya I really want to do this now. I just went out and looked at the compressor and exhaust manifold. It is dumb how close together they are. Ford even insulated the A/C lines that exit the compressor up to a certain point but not well enough I think. I think it would be best to wrap the manifold while I am at it too.

Now that is a toucgh call. Wrapping tends to lead to rust on a manifold in short order. I wrapped my rubber line above the manifold all the way up with 1'' dei wrap tape. I will probally end up doing the hard lines as well where there is a closeness to the manifold. I think IMO that a heat shield would be sufficent. The tape Reflects the heat away which is really the problem I believe. With out the heat directly on it, the problem shouldnt be that large. When I did my alternator it actually picked up 1 volt from just making the shield. It was close to my downpipe and was cooking. A nice heat shield with about 1'' of free space between it and the compressor would be great.
