99 seville sts overheating

First issue was, most electrical stuff like radio etc.. will not work for driver 2. if car set for driver 1 everything works. Then engine started to over heat. I have replaced filler cap, thermistat, and checked the small hose to see if blocked, it's ok. Ther is now coolent surculating through the cooling system. Both radiator hoses don't seem to be getting any coolent moving thru them. Both fans are working and both increase speed when temp rises. Any ideas??????

Did you check the small hose (purge hose) with the engine running?.

Also check the water pump belt.....is it slipping?....or maybe it has come off completely?

Sounds like a loose connection on the battery. Clean and tighten them, and check the battery ground. Is the starter cable on tight? If still nothing, a shop needs to check the ignition switch for a defect.

I need a cadillac seville sts 1998 4.3L & 32


Check for coolant flow at the Purge line,this is a common problem on the Northstar.
There is a small diameter hose coming from near the top of the coolant tank,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.If the hose is clear, check for blockage at the nipple on the tank.

My retired uncle has a 97 cadillac deville sts that runs well but after a short distance or time idling begins to overheat. He has replaced the water pump, thermostat and had the radiator and head gasket checked. Unfortunately he lives in a rural area and there is no local cadillac dealership for diagnostic repairs.
