Help! 1991 Suburban cuts out suddenly, immediately restarts. Tried everything.
Excessive AC voltage "confuses" [for lack of a better term] overheats or overloads electrical devices. Like I said have seen it cause a multitude of odd electric issues. Remember one vehicle, [Northstar Caddy] bight me real hard in the backside. I never checked the AC voltage until 2 days...- fast 99

Help! 1991 Suburban cuts out suddenly, immediately restarts. Tried everything.
Check alternator, both AC and DC. AC reading near .10 [one tenth] justifies further testing of alternator. High AC isn't all that common. However, very easy to check with a digital volt meter and will cause all sorts of odd driveability problems.- fast 99

Turn signal circuit fuse is "hot-to-touch" - excessively warm
Visual inspection and start disconnecting circuits to find the offending area. Then proceed from there. Install a circuit breaker or limiter of some kind. Do not install a higher amp fuse such as a 30, unless you like replacing harnesses.- fast 99

Replacing a single frame rail, can it be done?
Washington state used to do VIN inspections on out of state vehicles, generally not now. Still do home built [trailer], rebuilds, non-titled registration in cases of a lost title and inspections for abandoned vehicles at tow yards.

Front discs won’t release
Amazes me how many proportioning valve are replaced on this forum. Obviously this vehicle needed a replacement. Bet in my entire life as a tech, replaced less than 5. These vehicles getting older might explain it. -
Bad miss - could use some thoughts from y'all
Can remove plug wires one at a time running to possibly isolate cylinder. Checking compression might narrow it down. A vacuum gauge is a good diagnostic tool for misfires, faster and easier. Many times will show a mechanical fault. Check for vacuum leaks. Dieseling suggests a vacuum...- fast 99

Transmission Fluid Question
As far as I know Dex 6 is just a higher quality synthetic version and can be interchanged with dex 1,2 or 3. Usually don't use it as a replacement for the older versions because of higher cost. Oil is expensive enough.- fast 99

Truck Overheating
Factory gauges are indicators and can't be relied on for diagnostic purposes. Mechanical aftermarket gauges are reliable, hint. As I said before, if not pushing water out it's likely not as hot as you think. Immediately after shut down engine will hot soak. Coolant temp will rise, sometimes 20...- fast 99

aftermarket heads
Cracked heads is a possibility on old vehicles. Before I spent 500 on the original heads look into aftermarket availability. Even the cheapest aftermarket head will flow better than stock but be careful selecting which one. These trucks are heavy. Too much cam or large port heads will sacrifice...- fast 99

Truck Overheating
Yes a hot motor can do that. Called run on and can be very damaging. There are many other causes as well, low octane, high idle speed, if equipped idle solenoid adjusted incorrectly, vacuum leak, just to name a few possibilities. Until the problem is fixed shut the engine off in gear [auto] or...- fast 99

Truck Overheating
While you suspect overheating is it actually doing so? Didn't mention pushing water out or knocking after shut off. Nearly every time an overheating motor will do both. Infrared heat guns are inexpensive today. Get actual temps not "the hood is hot "as a diagnostic conclusion.- fast 99
