Husband 76 B.P. Is 100 over 55 he is dizzy and feeling tired, He was in Hosp . Overnight had temp.39.7 he has the shakes and is hot and cold?

Possibly so it is imperative that you get to a hospital as quick as you can
call the ambulance now

If vehicle reads hot when it sits overnight and is actually cold, there is an issue with the temp gauge... temp sensor... wiring.... . You didn't state year/make/ model so it could even be a BCM issue.

89, the dizzy loves to fail. it has a standalone dizzy until 1991.
so the ECU does not make spark on 1.6L , 1.3L is carb car.
the dizzy ignitor or VR devices like to fail hot.
check spark with it wont start bingo , bad dizzy, next?

could be tires need to be balanced . try that.

Although you didn't say if it feels like the shaking is coming from a wheel, it sounds to me like you have a bad tire even though they are new. Take it back to where you got the tires and have them take a look. If they can't see anything, ask them to take it for spin.

A shop didnt find anything? You have a suspension problem Lets start at the tires is there any mud or crude that affect the balance of your tire? What about wheel bearing is there side to side movement even with the rear,How about the upper ball joint and lower ball joint . a warp drive axle can cause this . If you are certain of there inspection with the suspension the problem is the torque convertor. If that stays lock up whoa you will be shaking like big time

if the shaking is coming from the rear end, have you checked the tires to make sure you havent broken a tredd in the tire and make sure the tires are balanced correctly and one hasent lost a wheel weight and thrown it out of balance. and check the air pressure in them also. check all tires i hope this helps

The shaking may be remedied by having your tires balanced
I have no idea what "Guatemala" means in this context
Sounds like you're asking about a temperature guage that is faulty or a faulty sending temperature sensor

Try getting your tire balaced as you ight have a tire that has seperated from the inner wall, as it sits overnight it will cool down then when you drive it the rubber sofens and the vibration will improve. I have had water in the tire too but i don't think thats your problem.
hope this helps.
