I have a 1997 dodge ram 1500 4x4 with a 5.9 360
It started over heating slow over the last mouth or so i dont know
what it could be . I put brand new heads new water pump new thermostat and a fan clutch. please help

 

Well some more details would help. But, lets start with basics. Any leaks? Overflow filled to proper level? How good/bad is the radiator? Heater core? When does it overheat? Highway speed, idle?

 

yes, all this would be good information to know. could be a bunch more things that you have yet to look into. i.e. radiator.

 

Besides making sure the fluid level is good and the rad is good as stated above, did you check the T-stat before install? And did you buy a good one or a cheap pos?

 

Well the radiotor looks fine not cloged from what i can tell
the thromstat i did test on the stove it opened at 190 and my fluid is full also it seems to over heat a lot faster when im in start an stop traffic.Its killan me i just dont now wat to do

 

Nope, you can't go by that. I made the same mistake several years go and the radiator was plugged. If you are looking in the neck to see water movement it will fool you every time. You could have 90% plugged and still see water moving. Take it to a radiator shop and for $30 they can open it up and tell you how badly plugged up it is. I think I paid like $50 and the opened it, rodded it and closed it back up, and never had a problem since. A new one was $150 for a cheapo brand, back then.
