Covered both my starter and CKP in remaining DEI radiant barrier. Will order a new sensor soon.

Starter wrap

 

You can buy a spare, but I can almost guarantee it will never fail now. I had one going out - if I ran the truck, parked it 10 mins, came back it would not start. pour water on it - started. Cold started every time. I put a heatshield on it a year ago and have had not problems since.

 

Where might one find this heat shield material?

 

Here you go @Brandon318

 

I really like the idea of heat-shielding the crank sensor, kudos.

Jury is still out on wrapping a starter in insulation, though. The starter motor itself can generate a lot of heat if engaged for any length of time, so insulating that internal heat might work against you.

However, if your Disco always starts up instantly, then it makes sense to insulate the starter from the cat's external heat.

Hence, jury is still out.

 

A fair point. So far my starter is pretty quick on the job. I'll hit it with a temp gun after a cold start and see what it looks like after starting.

 

You only need the heat shield between the starter and exhaust. Chevy starters (Disco is very similar) used to have issues when long tube headers were installed (back in the day before heat shields). Didn't your Disco have a heat shield on the starter? They come with one from the factory.

 

No heat shield on the starter as far as I can tell. I will double check tomorrow.

 

Oh awesome! And it just self-adheres?

 

They have products with an adhesive and some without. The link I sent you has a strong self adhesive on the back.
