*getting Hot*
 

so yesterday i drove to san clemente( socal) and it was a hot day and i had to take the 241 toll road. as i was going about 70-75 up the 2-3 mile incline my car temp started rising higher and higher. i just bought a fluidyne rad. and i havent had any problems until yesterday when i went up this incline. can anyone please give me ideas on how to take care of this situation.

thanx

Did u make sure to burp all the air out of the system when u put the radiator in?

Do you have an aftermarket temp gauge? If so, what were your temps. More detail is needed. If you have the stock gauge, it wont provide good info. Get an aftermarket gauge if you don't have one.

Did you have your A/C on? What did you do when the temps started rising?

i did the air bleeding when i put the new rad. in. i dont have an aftermarket temp. gauge so i dont know the exact temp it was at. i did have my a/c on but as soon as i saw the temp going up i turned it off. so what do you guys think?

has anyone had any problems like this at all? (during inclines). oh i was also in 5th if that helps so the rpms where low.

do you have aftermarket pulleys on your water pump and alternator?

hope that it's bad t-stat, rad cap, or air trapped in system. assume u have belly pan installed.

takes a lot to get stock gage to move up ... 240F+

It is normal for the temp to rise when climbing a hill. It shouldn't get to 240 or more. Turning off the AC was a good move. Since the radiator is new, that isn't the problem. I suggest replacing the thermostat, and checking for air in the system.

You really should get a water temp gauge, and a boost gauge.

AdamC is right, it's normal to heat up going up a long incline, especially in 5th gear. The reason being is your are constantly boosting several psi when going up an incline in 5th. The constant boost heats up water (and oil) temps quickly.

There is something wrong with your cooling system if the stock gauge moved though. I hit 230F at the auto-x when my t-stat was bad and the stock gauge never moved a single degree -- it was still pointing a hair below half way.

thanks guys i guess i will have to figure out a time to get to the t-stat. i dont have a pulley kit either. its just so irritating seeing that temp go up like that. has anyone done a t-stat install? i thought you had to take off the aluminum filler neck to get to it? is this right?

yes

As an aside, I noticed going up the mountain passes around here that as rynberg mantioned, you are boosting going up the inclines due to the increased engine load. To control temps when I travel to eastern WA, I cycle my acceleration by giving it say 5-7 lbs boost for 30 seconds, then getting off the throttle, then boosting again, and so on. Keeps the temps down to 200F at most, and these are 20 mile climbs!

What REALLY kills my motor is going up 2 to 3 mile inclines at 35 mph. No significant airflow over the radiator means I get to run the fans the whole way to keep the temps under 200F, but by the top of the hill, the IC is literally too hot to touch. Good thing I get to park it and let it run for 5 minutes with the fans on and the hood up after THAT madness...

I'm silly.
