Ok here goes. Overheating wj 2000 287 cu.in. v-8. Tis ok on the freeway
but low speeds or 4wd it really starts to cook and around town and
small 1/4 mile (hills). Has anyone know or have experience in this field
with all aluminum radiators. I've found that some are wider than others,
so the real question here is about the condenser. Will these aluminum
rads. fit without to much shoehorning?
Do this...when it starts to over heat on the highway, run the heat full blast. windows down so you don't fry. If it keeps the temp low, it is a radiator issue. If not, it's a water pump issue. Or it could be failing to hold pressure and the cap is leaking...
My bet is running the heat will solve it and you need a radiator. Aluminum ones are rare like frog hair. An OEM spec will do the trick for another 4 years.

My V-8 does not get hot on the freeway.
It gets cooking at very low speeds,city driving, and going up small
inclines or hills.It does have the factory tow package, if you want
to call it that.I just installed a Hayden clutch fan last month. The electric
fan does come on, but I do not know how to tell if it is running on low
speed or high speed, but my way of thinking is that these vehicles
should not need secondary fans.That just tells me that they are way
under cooled. These vehicles need a lot more cooling, like another
gallon or more. I know these are stuffed under the hood, but the engineers
should know better than that. I would get into the wife's '07 and the way
they cobbled it up, but I would have to write a short novel on it.
This is about aluminum rads. remind you.
Thank you all, more input please.
