If you replaced everything, you should start with listing what everything is. Also when you replaced the hoses did you use origional molded hoses, or did you use genaric heater hoses. The generic hoses like to kink up and stop water flow. Did you replace the thermostat? is it the correct temp thermostat for your region. Are you using the correct coolant? Do you have an electric fan? is it turning on at the correct time?

Yes when you do major work and replace a lot of the cooling system you in my opion should flush out your cooling system. If you are so inclined you can do this your self. Just do a reverse flush and make sure your force all the **** out and use the correct chemicals to get rid of the gunk without hurting your radiator and heater core.

Also, is your radiator getting enough air. a lot of people like to put stuff infront of there grills that cover there radiators which reduces air flow. If you can check on all this and let me know the results I can give you more info if you are still having problems,, I have had several Jeeps and loved everyone of them. They are very easy to work on, and will take care of you if you take care of them.

Yes - Your radiator not only needs to be flushed you could also have an inexpensive procedure done at any reputable radiator shop called "rodding out" and then heat flushed. If I remember correctly 98 Cherokees have a 4.0 in line 6 cylinder motor that has a aluminum radiator. If you remove your radiator yourself (drain detach hoses and unbolt assembly) and bring it to the radiator shop you could get this done really cheap. If you are not comfortable doing this, have them do it for a slightly higher fee. This should really help. NOTE: When adding radiator fluid from now on, use 50/50 premix or if you mix it yourself always use DISTILLED Water. This prevents corrosion buildup in your system. Good Luck!!!

While driving my 1998 Mercury Sable with the heat on. It will start out with really warm heat and then 40 seconds later it willstart to cool down. If I turn off the heat and wait wait a minute it will


This sounds like a classic problem with the heater core. The heater core is like a small radiator that is located under the dash (likely). If the vehicle hasn't been maintained properly with regard to the coolant, the heater core can become clogged over time and need to be replaced. Years ago, there was also a problem with mixing the green and red coolant. This caused the fluid to gel especially in the smaller passages of the radiator and the heater core. Did you install an in-line port when you flushed the system? A little household water pressure flowing thru the system might help blow the clog out. Other than that, replacing the heater core Will likely solve the problem. Good luck!

It could be the fan clutch not engaging which will not pull air through the radiator, it may still appear to be spinning but it could not be at the correct RPM for adequate cooling. Hope that helps.

Ford Taurus Heater won't switch over to AC


I guess first thing to find out is why compressor is not coming on, as without that running you won't get any cool air. May just need a recharge, but I would have that checked out first. If system is low on freon, it won't engage, and if it is low, why, as in where is leak & how much to fix it, would be my first concern.

1998 cavalier heats up when idleing. Fan comes on but still heats


Hello senior, whenever the coolant system is opened up there's a possibility you could get air in your system, only way to get it out is by using the bleeder valve, check the coolant temperature sensor it may not be working properly, it tell's the cooling fan when to kick on and off, the condition of the drive belt is also another factor, along with the tensioner and tensioner pulley. it sounds like a problem with the water pump, the cooling fan, or air in your cooling system, to get a good inspection of the water pump fin's you have to remove it.

You need to get the cooling system flushed and the thermostat replaced. The fan switch he referred to is the cooling system fan switch. When you A/C is on the computer turn on the fan constantly to help keep the engine cool under the extra load.
