I just put a CSF 3 all metal 3 row radiator in & works great. But you may wanna try new heater hoses & did you use silicone or a gasket when u did thermostat cause too much silicone may mess with flow of heater hoses.

i used a gasket sealer for the thermostat! a 1/8th inch bead all the way around im gonna replace thermostat with new stant one tomorrow and see what happens!

Have no clue what this would do but i checked to see if my fans were working and my electrical fan was not working! is this normal i mean the temp was atleast at 210 if not hotter!

my 94 loves 210, my electric fan starts at around 215. My mpgs and power suffered with the 180 t-stat that I initially installed. I freaked out when I first bought my jeep and saw it hovering at 210. I put a stock type t-stat back in when I had no heat the following winter.

210-215 is fine.

Cool thanks for the info!
Really? i kinda thought that was not good for my jeep! So i just shouldn't worry and just drive it?

I freaked just the same. I stay around 210 while driving. It will only rise above that when I am at a stop and it has to be stoped for an extended period. I have noticed that for some reason now that it is warmer outside the engine temp runs a little more consistant. Seemed that during the winter my engine would stay warm and my fan was always kicking on.

yes jeeps like two run at 210* i have the CFS 3 row in mine, at stops it can go over 210 but when i start driving again it will go down. it sounds like you have most of your cooling replace, as long you check on it now and then you dont have to worry.

but if you see that your going over 210+ i wood start looking in to things a bit

yes deff something ive noticed too

My 01 sits at 210, all the time, it I let it sit, the electric fan comes on and it just stays around 210-215, seems to be fine for it.

mine runs around 240 all the time. never had a prob for the past 2 yrs i owned her.

240 degrees is an overboil. I would never let it get over 215. I'm at ~195* or under all the time. I turn the heater on and after 10 min my temps drop to 160. My heater works great also.

Alum 2 row radiator
fail-safe 195* stat
paper gasket on thermo housing with no leaks
new upper and lower hoses
green coolant
vacuum flush 3 times during system renewal removed chunky milky goo that was stuck back in the motor.


I towed a 2800 lb load up cajon yesterday to silverwood and I never saw it get over 200*.

the I6s run a little warm but with some of the later years the computer will automatically shut down the engine when it gets way too warm but as for it running 210-215 thats normal. Most engines run that warm, I know cadilacs northstar always ran between 200 and 210. As long as your electric fan continues to kick in around 215 the engine will be fine.
