SOURCE: Water Pump

The water pump is driven by the timing belt, so if you don't know what you're doing (no offense intended), I would take it somewhere to have the work done. And if you need a new timing belt as well, you should get that done at the same time since since the labor rates for a water pump and timing belt will be very close to the same, you'll be adding mostly parts cost.

It's a big job. Drain the coolant down, recover the freon in the ac system and disconnect the lines and heater hoses. Lower the steering column, remove the instrument panel assembly, remove the heater housing. Split the case halves on the housing and there you are. Usually around 500 to 700 dollars at a dealership.

Not a whole lot different. Just need to keep removing plastic down at the heater until you get to the heater core. Then disconnect it on the firewall side.

How come when I start up my 1999 Cadillac deville I smell antifreeze real strong through the vents ? Is something wrong?


The heater core may be leaking / faulty - not familiar with Cadillacs, but normally it is located inside the car, behind the dashboard (glovebox) on the passenger side (near the blower motor). This may be something for a mechanic to diagnose if you are not familiar with automotive heating/cooling systems.

Is your floor wet on the passenger side up front and smell like antifreeze? If so, the heater core blew, but it's not hard to replace.

My cadillac is not giving me any hot air ,ive replaced the radiator, changed the thermostat, has a new water pump, where do istart to look.


Feel the 2 tubes at the firewall for the heater core. If they are not getting hot, the heater core needs to be flushed out or replaced. I had this problem with a 1990 Cadilac Deville, it was just a plugged up heater core.

Remember to install sealant after flushing out the system to prevent leaks.
