Bulkhead Heat

I have noticed in my 110 my bulkhead is extremely hot. As I drive my toes get hot and I reached down where the pedals are and the metal is hot to the touch. Is this normal? I never noticed it in my 90. I dont have kick panels in right now. Also my AC stopped blowing cold so I have no clue if this is related.

Out of tune or out of time can cause excess fuel to end up in the exhuast where it is burned in the cats causing excess heat. Or, you know, it could be normal and you are crazy.

One of my buddies and I bought '93 NAS 110's new. He ended up putting ceramic coating on his floorboard and bulkhead because of the heat - I never thought it was that bad on mine.

I would not dynamat if it gets that hot, it will just melt and slide around. You want to do a few things, get an IR themometer and check the temperature of the exhaust running under it to see if it is unusually high. You can put thermal insulation on the outside, add heat-shielding etc but knowing if there is a problem is the best first thing.. if you are afterburning it is probably something you want to know because unlike on a jet, it doesn't make the Defender any faster

Bulkhead heat

The heat helps clear out the rainwater that is flowing in after each storm.

NRP reportedly has not sucked for a few years (finally used SS for welds), but that is just rumor.

PS it is still light out JimC, get back to work on the truck.

I had a similar issue with my Defender. One thing you haven't mentioned which I experienced is an increase in the temperature when in motion.

Turns out there is a plate or cover missing in the firewall which was letting heated air from the engine compartment come into the pedal box. I can't remember exactly where my guy said it was, but I remember it is a part which sometimes gets left off when they work on the clutch.

When I first drove the Defender with flip-flops, I swore my toes were going to catch fire...
