My 1995 isuzu rodeo has been bubbling and the tempature rises, but only when i have to stop and sit like at red lights and stop signs.When i'm on an open stretch of highway the tempature will go down and be fine. The water pump has been replaced and the water cycles thru. some one told me to flush the radiator but i don't know how they said i could buy a product that will do this. If anyone has any ideas on what this might be or what i can do i would really appreciate it im a single mother of 3 so my income is really limited.

hello, there are several things you should check. the radiator may be partly clogged, or the thermostat my be stuck. since you aready replaced the waterpump,you can probably rule that out. check to see if the cooling fan is coming on. it may be as simple as a fuse if it is electric. if it is nit getting hot going down the road,you should have enough water flow which would make it seem un likley that it is the rad. partly blocked; but dont rule that out completely. i would start with the fan first and work your way back. you neen good flow of air and water while sitting still. if its not the fan check the thermostat next.

Head gaskets are put in incorrect each and every of the time. besides the undeniable fact that that could be a cracked block the place the crack in basic terms opens up whilst heat. only bypass away the thermostat out till you come across the concern. between the advantages of it somewhat is you will discover the water circulating. electric powered water pumps have been between the dumbest concepts ever and by no skill could have been on engines. Get 2 temperature strips made for the purpose and placed them on the two radiator hoses. which will inform you if the radiator is doing that is interest. and don't use money as an excuse to substitute that aluminum piece of crap with a competent copper radiator. it is going to value you plenty greater money if that is not doing that is interest. placed an exhaust gasoline analyzer on the radiator. you do no longer constantly see effervescent precise off whilst head gaskets leak.

Yep, its probably the fan. Does it have an electric fan that's suppose to go on when the coolent gets hot? If so, it might not be working. Maybe its just a fuse? Or the temperature sensor that turns it on, or the motor itself. When the water pump was replaced they probably changed the coolent because I think it all runs out when you take off the water pump. Anyway, you'll probably get an answer from a mechanic that works on them and has seen the problem before. Good luck!

DON'T FLUSH THE RADIATOR, no matter what your mechanic suggests. 9 times out of 10 you'll be replacing it a month later. Your radiator will rust and crack over time, but any build-up in there is keeping those weak spots sealed. A flush will remove all of that and weaken the radiator.
The most likely problem is with your thermostat, especially if you just replaced the water pump. Start there, it's not too expensive.

I don't think the thermostat could be a problem because the temperature seems fine on open stretch. I suspect it could be either your radiator fan or your radiator. Get an electrician to check the fan and a mechanic who specializes in radiator to flush your radiator from rust and dirt accummulated in there. Top up with a good radiator coolant.

If your radiator cooling fan is electric, it is probobly not turning on. when you drive the car, the cool air coming through the front of the car will cool the radiator, however at a dead stop the engine will heat up if the fan is not working. One way to check is to open the hood when the car is hot and look to see if the fan is running.BE CAREFUL!! I recommend that you have a male friend do this for you. It is probobly something simple like a fuse.

Have you flushed your coolant? Its usually only $5-10 and a water hose and 20 minutes and you can do it yourself. Then of course add fresh stuff in. But I agree with the other guy that its more than likely your fan, with no air circulating around the radiator your fluid heats up...

If it overheats going slow, make sure the fan works. Any vechile in hot weather that stays running parked with the a/c on may overheat.
Your problem, if there are no water leaks, is the thermostat of the fan for the radiator.

There are several things that need to be there in order for your cooling system to work well. One, your coolant should be a 50/50 mix of water and antifreeze. This will prevent corrosion and raise the boiling point of the coolant. Two, The rad cap should be able to pressurize the system to usually 15 PSI. This also raises the boiling point of the coolant. The system should be clean and no collapsed hoses.

The computer, coolant temperature sensor, the fan relay or the fan motor, just to name a few. The cheapest is the fan relay, but I would get a good diagnosis before I started swapping parts, or you're throwing money away. Hope this helps. (The relay is the most likely to fail, but I had to replace my fans at 50,000 miles on my four year old car)
