Question about 1997 Dodge Dakota

1 Answer

New water pump and thermostat also flushed radiator and backflushed the heater core. Only heats up to 170 heat goes away once you slow down. When running down the road it has some heat but not near hot enough. Radiator never builds up pressure no matter how long it runs.New radiator cap too. All hoses clear and cooolant is flowing thru but hardly no heat.

    Are you losing coolant? Usually a no pressure buildup condition would make me think there was a leak somewhere in the system.

    It sounds like you've hit most of the major points already (pump, thermostat, backflush, etc. What temperature 'stat did you put in it?

Have you backflushed the heater core? Check to see if both heater hoses are getting hot and if not flush it if possible. NOTE: most modern cars run hot water through the core at all times, but direct the inlet air through the core to supply heat by use of flapper doors usually operated by vacuum actuated devices. Vacuum leak, bad check valve to vacuum reservior, or bad actuator can prevent any heat.

1998 ford Escort zx2 Heat is slow getting warm. Temp gauge barely registers. I have reaplced the Thermostat, radiator cap, blew out heater core. No heat when in idle but works once driven. What now?


Water pump. First make sure you have enough coolant and the reservoir system isn't leaking(or any leaks). Fords are hard to get air out of the system. I always over fill Fords because of air. It will usually purge out in a couple days. only getting warm at idle and hot going down the road is a water pump or something is still clogged up. IE.. heater core.

What would be the reason I have no heat in my 1998 Plymouth breeze after changing thermostat water pump antifreeze?


You probably have a clogged heater core, which basically is a miniature radiator under the dash. Hopefully, If the core is backflushed it will serve you well once again and you'll have heat again. Good luck.

If both heater hoses are getting hot, the problem could be a stuck blend door under the dash.
If only one hose is getting hot, there is a blockage in the coolant flow somewhere.

No heat on 1999 blazier


Water pump may be worn and needs to be replaced. You can try flushing out the heater core it self buy disconnecting the two heater hose from the water pump and flushing water through it to get any restriction out. Once you flushed out the heater core, reattached the hose at the water pump and see if that helps. If not then your going to have to replace the water pump it self. Good luck

No heat


You probably just need to backflush your heater core. You can use a hose to flush it back and then forward. You'll be surprised at how much sludge and gunk will come out.
