I got a wiring harness on my engine that melted on the exhaust manifold. The wires are still good but are bare now and I need to repair them. Problem is, in order to do it the way I want to, I have to basically rip the engine apart just to get to them. Just wrapping them with electrical tape is going to be tough. Is there a liquid type covering that I could use that I could maybe brush onto the wires to cover them up or do I need to just do it right and tear a bunch of stuff off the engine to get to them. To get to the wires I would need to remove the power steering pump, A/C compressor and maybe some other crap behind those. Any ideas?

When you get down to it removing parts that are in your way make the job go much smoother. Another thing to remember is reliability. Do you want to be redoing the job on the side of the freeway?

Cool. I didn't even think about that wonderful tool called Google...lol. Thanks. As far as doing a repair on the side of the road, I think I would have a better chance of not having to it if I at least put something on there rather than leaving them bare. Trust me, I will get them repaired the correct way when I have time to do it right. But time is not on my side right now and I need a quick, temporary, but reliable fix. Thanks again guys. As always, I can always rely on my heli family.

What kind of car is this on?

Do you by any chance know the wires that are affected are for?

It's on a 97 S10 w/4cyl. I believe it is the harness that has the oil pressure sensor and speed sensor coming from the transmission. I had issues with both of these a couple of months ago and when I had to get the truck inspected, they failed the truck for instruments not working right. I was having issues before I took it in and I knew it would fail for it. I replaced the oil sensor and the speed sensor with no luck. So other than doing those two quick replacements, I didn't have time to dig into more to troubleshoot it. When they inspected and failed it, they said it was a harness shorting out on the exhaust manifold. I said ok, make it work so it would pass. All they did was put some wire loom around it and it was good. A couple of weeks ago, I was replacing my waterpump and radiator and while doing the lower hose, I saw the wire harness sitting and melting on the manifold again. When I went to move and reposition it, the loom just flaked right off and left me with 4-5 bare wires. I am not having any issues right now with my instruments and the truck is running great. I have the wires seperated so they are not shorting out on each other and it is pulled up and away from the manifold now.
