Working on replacing the timing chain gasket on my 99 ford explorer 5.0

got to the point of some seized bolts and not sure what to do.

using a big blow torch sounds like it would work best but I don’t have one and I don’t want to strip my motor down enough to do it safety.

After a while I remembered inductive heating. Fortunatly there is a tool for that! Unfortunatly it is like $500. But it works really well!

After some more thinking I decided to go more of the DIY route and bought this for $13.

I needed a power supply so I grabbed an old PC power supply. Using some yellow 12 volt wires and the black ground wires. Needed to add a power button by bridgeing the green and black wires on the 20 pin connector

Yay it heats up a paper clip to red hot in about 8 seconds!

I needed some sort of project case to use in the actual repair!

The bolt I needed to heat up was larger then a paperclip so it took longer to heat up. Doing a bench test after about 2 minutes I was able to get the bolt to about 600 degrees!

In the end I couldn’t generate enough heat when the bolt was in the block using the $13 inductive heating unit. A $55 handheld torch did the job.

Gasket replaced!
