: How can I protect my new starter?

03-13-11, 02:45 PM
Hey guys. I'm going to be replacing my starter this week and I've heard a lot about them being affected by heat from the manifold, especially the wiring. So what do you guys use to protect your starter and wiring? Also, which wiring is it that seems to get fried up?

I havent replaced my starter myself but there are lots of products out there to protect wiring and I would think a good heat wrap sleeve would be sufficient.

I used some adhesive heat/sound insulation. Just cut it to size and stuck it on. It seems the biggest problem though, is the starter solenoid connector. The heat melts the plastic clip that secures the harness in the solenoid. Once its melted it works its way out until.....one day......leaving you stranded.

My starter got baked. The day I got it back from the dealer with a new starter I installed this:


Starter wiring: Thermo-Tec, Express Sleeve w/velcro, #14030, 1" x 3' (cut-to-fit), $29 at Summit Racing
Starter body*: DEi Heat Screen, #010401, 36"x40" (cut-to-fit), $56 at Summit Racing
11" stainless steel cable ties, $5 for 10-pack at Lowe's/Home Depot. No messy adhesives.

*Here's originally where the DEi Heat Screen went for protecting the differential from any unnecessary heat from the exhaust. The leftover portion was just enough to cover the starter. I'm sure with a little searching on Summit's site you can find a much smaller size from Thermo-Tec or DEi.

The exhaust preheats the diff.
