How to add coolant to the radiator if recovery tank is defective?
Tom thank you for your quick reply. The coolant tank is full. DIC continues to
advise, "Check Coolant Lever". I have run the engine with the cap on and
with the cap off. Makes no difference, I can't get coolant into the radiator. I've
taken the car to a mechanic who returned the car saying that correcting the
problem was simply too difficult because correcting any problem of the blend
doors required extensive disassembly of the interior, and he didn't want to do
it. I have a quote from another mechanic that is in the hundreds, but he does
not guarantee that it will cure the problem. I myself removed the recovery
tank, washed it out as suggested by a Youtube Video and replaced it, all in
about a half hour. Has not helped. I can't drive the car if I don't get some
coolant into the engine, so that is paramount!
This is only the urgent problem. The fuel sensor doesn't work either. I've
read dozens of complaints for that also. That suggests the replacement of
the fuel pump along with the sensor parts. I will probably never ever
purchase another Cadillac, regardless of price!
How do you know there is not coolant in the radiator? Did you loosen the petcock on the lower part of the radiator and no coolant came out? Your going to have to spend money either way to correct your issues. How you go about doing it is up to you. Have you considered selling the car and purchasing another? Just reply to this post, no need to start another.
Sounds like the coolant level sensor is bad or the wires going to it are shorted. Either way you're probably getting a false reading. Is the car overheating? What year is your DeVille? As for the climate control system, I'm not surprised that your mechanic can't fix it. Historically speaking Cadillac climate control systems are Cadillac only and require special knowledge of the system to be able to fix it. HTH. -Jim
