Overheating 1999 Cadillac DeVille Delegance

Asked by May 10, 2017 at 09:11 PM about the 1999 Cadillac DeVille d'Elegance Sedan FWD

Question type: Maintenance & Repair

I bought the Cadillac drove it across
the road and it wouldn't crank then they
put in a new alternator, drove it home
and it started spuing water from the
front passenger side tire (around the
area of the coolant reservoir) took it
back they put in a new radiator after
driving it 10-15 min it says a
temperature of 244 and the coolant
reservoir is bone dry. Also states the oil
life is 0% but it is obvious, due to oil on
dip stick, it has oil, black to the color
but seems not as thick.  After 2-4 hours
of rest the car will crank and read
temperature 195.  Been told it's the fan
relays or it's the water pump, or (from
my research) coolant reservoir ($10
aftermarket $50 factory), hoses could
be clogged, head could be cracked ,
(new put together motor, that isn't
Northstar but fits the year and model
$1000-1200......and up.  I'm just lost

I have a 98 DeVille that just started overheating and was a 3/4 gallon low of coolant. I filled it and it runs at 196 for 15-20 mins then slowly gets to 212, 222, 230 then back down to 201 for awhile. It does this for 30 mins and sometimes doesn't get higher but sometimes it gets to 245-255 which I kill it but it soon comes down. Could it be the thermostat? I don't see a leak.
