Hi Folks,

I bought a 2004 DTS (blk/blk)about a month ago with approx 60K miles on it. Reading around this post I want to change the engine coolant asap.

Can someone forward me or point me in the direction to the specific proceedure to accomplish this task? I didn't have any luck in FAQ regarding the step by step process.

ALSO, the heater/A/C fan will not operate- sometimes the climate control will kick on if I go over a bump or accellerate aggressively- indicating it might be a bad connection somewhere. Possibly a blower motor connector? Where can I find this connection.

Thanks for any assistance and providing an invaluable source of information on all Caddys

Thx
Sully

 

Flushing cooling system - Drain old coolant, refill with coolant, monitor level till cooling fan comes on and goes off 2 times. Re-install cap drive 2-3 miles and park. Recheck coolant level add as necessary.

Blower - check for codes, blower is under right side of dash.

 

not to over-ride the master, slowroll, are we suggesting dex-cool, distilled water, or pellets/ additives for this guy? maybe none is needed due to the miles on the car..... just a suggestion.......
cescully, big welcome to the Forum..... keep us posted on your coolant change.... good luck

gotcha... just wondering if the bottom radiator hose is the best method... and should I be forcing the remaining old coolant out by some type of water pressure, say from a garden hose?

thx
Sully

scully, if i remember correctly a simple drain is good enough, see my post on the same, somewhere (i'll look up and get back).
