If radiator hose pops out is because pressure builds up when water expands due to the normal operating temperature of coolant when car runs, that pressure should move to the expansion tank instead and wait to be sucked in when engine and coolant cool off. Check the line from radiator to expansion tank and you're losing coolant, add some more every time after each driving circle when engine is cold until you figure out what's wrong, it will save you bigger troubles.

Usually, hoses pop off if the radiator/expansion tank cap is incorrect/broken. Find out if this "mechanic" changed the cap, if they did, get the old one back or get a replacement from the dealer. I have never gotten a dependable replacement from any parts stores. If they didn't change it, change it anyway and see what happens.

Probably not water pump. Engine is notourious for vapour lock.
Cooling system must be blead of air before thermostat will work. Cool bottom rad hose is a dead give away. If you are still watching this forum reply , and I will walk you through the only way I know how to make it work properly. It's actually easy if you do it my way. I have worked on lots of cars , and this engine was the hardest to bleed out. Did one Yesterday , and works perfect.

SOURCE: 2005 Chrysler Pacifica Washer Pump

The washer pump is located in the bottom of your windsheild washer reservoir. You will have to remove the wheel well cover to access it and check the plug in harness to make sure it is connected. Place a voltmeter on the to leads of the harness and have an assistant push the windshield washer button with ignition on. There you will see if your getting volts to the end of the harness. If you do, then the pump is bad. Replace it while you have access to it.

After changing the water pump and timing belt on a 2005 Chrysler Pacifica 3.5 the engine will idle but surges when I accelerate. There is no codes being shown.


i'd advise rechecking the timing belt positioning again , surging can be a symptom of timing being out and i would'nt expect any codes if its the belt timing, as is set up manually and not monitored by the PCM

Windshield Washer Pump connection to the water bottle


Take the rubber hose loose at the nozzle, try the washer. if water comes out then the little hole in the nozzle is stopped up. Use a small needle or stickpin to clean it out while someone works the washer switch.

I have a 2005 Chrysler Pacifica. While driving I heard a faint sound almost like a pop. Then steam coming from the front drivers wheel well. Then I noticed the heater will only blow cold air. Can you...


The pop you referred to was mostly likely a radiator hose rupturing.

The steam would be indicative of a sudden, massive loss of coolant.

Do Not drive until problem is remedied.

Could also have been a radiator tank letting go, but I'd put my money on a hose.

Hoses are a LOT LESS COSTLY, and generally easier to replace.

Good luck!

I need to replace the thermostat for a 2005 chrysler pacifica


Follow the Upper Radiator Hose to the Block. There is a Bell housing there that the Hose Connects to. Remove that Bellhousing and the Thermostat is Right Under it.
