overheating problem Ok just been driving my car about 8 miles to work and out on the weekends. The gauge was reading around 200-210. Now for some reason my coolant light has been going on and off randomly and the stock gauge is going up to around 230. I checked my coolant there's no air in it and its full. What could be causing this? Leaks a small amount of oil from oil pan gasked but fixing it after I get off work, I don't think that could cause this problem though. Any help at all would be great

Yea the resivoir is at full. The water pump was replaced about 2000 miles ago. Lol its one of the few shiny parts on my car. The temp goes down some when driving obviously cause of airflow but when im stopped is when im havin problems, the fans work though. Checked them and the relay for the fans, both are good

It's a long shot, but do you still have the stock oil cooler? I just got rid of mine when I did my oil pan gasket and read a lot of posts saying it's a prime spot for bottlenecks. The lines get pretty small going into the cooler and they can get clogged pretty easily from what I've heard. It's verrrrrry easy to delete and cleans up some of the engine bay. You'll probably have to take the lines out to get to the bolts on the drivers side of the pan anyway.
Seems like your in the right track tho, not much else it could be

If you remove the radiator cap and run the engine to operating temperature, you should see coolant coursing through the radiator after the thermostat opens. You should also see coolant shooting into the radiator from the heat steam pipe return line, it's at the cap neck.

It's very easy to do. I dont have a write up but I can try to remember everything, I did it a few days ago. Here is a link to a thread that helped me out. https://ls1tech.com/forums/lt1-lt4-m...il-cooler.html
First step would be to drain the coolant
Remove the lower drivers side radiator hose (should be the hose that goes back towards the oil filter and runs along the oil pan)
Remove the lower drivers side hose from the water pump (should be the other hose that runs next to the the one you just removed)
One bolt holds the two hoses to the oil cooler at the oil filter, remove the bolt and take out the two coolant hoses
Take off the oil filter and remove the tube the oil filter screws into (it's like a 24mm, I used vicegrips) Once you remove the big center tube the cooler should fall right out
At this point you can reference the picture I posted in the linked thread. There are two bolts that hold the oil filter adapter to the block. Remove one at a time and grind/dremel/cut off the stud above the head of the bolt (You'll know what I mean when you get there)
Repeat for the other bolt, make sure you grind down enough of the head so the filter can screw all the way on (just feel with your hand to make sure the bolt doesnt sit lower than the mounting surface for the oil filter)
Once you get the bolts ground down enough and put back in, theres nothing left to do but cap the open coolant ports where the hoses were. I went to autozone and bought a package of caps that were located in the "help" section. http://www.autozone.com/autozone/acc...mString=search.
I didnt use any hose clamps, but I did use some of "the right stuff" sealant on the coolant ports to make sure they dont leak, and it's been fine for the whopping 20 miles I've put on since
You can also use bigger oil filters after this, I used a mobile 1 m-302
This is definitely one of those things that are pretty straight forward, you cant really mess it up as long as you cap the radiator and water pump after you remove the hoses. Let me know if you still have any questions, I hope this helps your problem. Either way it cleans up some of the hoses in the engine bay and gets rid of some weight

Even if drak03's oil cooler was completely blocked, it would not be causing the car to overheat. Getting rid of it has been done by many without causing any problems as it is a POS anyways.
OP, does your car still have the chin spoiler under the car?

I had removed it on my '94. It overheated even when driving.
OP, you have a few things to check. The flow in the radiator including the head steam pipe return should be first on your list. How's your gas mileage? Oil level? A stuck open injector can cause overheating, among other things.
