The radiator should not be too big an issue, just depends on what tools you have available and how much stuff is in the way... The instructions here will be for a 2.4L engine, which may or may not help you. You will need a 10mm socket or wrench, a 13mm socket with an extension, and a 5/16 inch wrench or socket. Remove the headlights, you should see two small bolts on either side of the transmission cooler... remove those bolts. Then, remove the three bolts holding the radiator to the engine bay (the electric fan, if equipped, should be near the driver's side of the engine, next to the washer fluid tube). Next, remove all hoses and oil cooler lines connected to the radiator (should be able to remove the cooler lines with a 5/8 inch wrench). depending on your situation, I removed the battery and fuse box near the battery, and moved the air conditioning lines out of the way in order to get the radiator out. As long as the two nubs that are on the radiator are disconnected from the transmission cooler, you should be able to remove the radiator with little to no resistance. Be careful to not bend any fins on reinstallation. Installation is the reverse of removal... depending on how you want to do it, it should take you approx. 3 to 3 1/2 hours... it took me 5 1/2 due to it bein' 103 degrees and I took several breaks. if you have any more questions, please let me know.

98 Pontiac grand Prix 3.8, over heating, antifreeze disappearing, transmission slipping, is it possible for transmission fluid to leak into the radiator?


Yes, your transmission cooler is inside of the side tank of the radiator. If your coolant looks like pink sludg, then there is a good chance that you need your cooling system and trans fuid flushed and a new radiator installed.

98 Pontiac grand Prix 3800, is it possible for transmission to leak into the radiator and mix in with the antifreeze?


yes --it is a common thing
the transmission oil cooler is in one of the radiator tanks and have a habit if cracking allowing the transmission oil to mix with the coolant
the fix is a new radiator and a very good wash out of the cooling system ( heater included)
I suggest that you use an accredited radiator shop and have then do the flush and the radiator replacement

I have a 98' Pontiac Grand Am GT. Car over heats in less than 2 miles and ?the heater blows out cold air, how can I fix this


Hi Josh-
I assume that you have the proper mixture and levels of coolant in your radiator and plastic overflow tank. Open your radiator cap (when the engine is cold) to make sure this is the case. If not, fill as directed by your owners manual.
If the cooling system's thermostat is bad, the hot coolant coming from your engine can not circulate to the radiator in front of the car to dissipate this heat and return to the engine colder.
The odd part you describe is that cold air blows out of the heater. If your car is overheating, you should have above average heat, since your car is running hot.
A bad water pump may also prevent coolant from circulating correctly. Usually, a bad pump will show up as a puddle of coolant underneath your car-since the bearing or seals usually wear out on the pump. However, I've seen where the internal blades or impellers of the pump have worn out due to deposits in the coolant due to infrequent replacement.
Hope this helps!

did you buy the right temperature themostat? believe it or not the cmptr is set to factory temps that require the exact thermostat. is the radiator cap on tight? does the radiator cap have a good seal.?......easy fix. lastly check vaccum hoses that run the climate door. the door may not be fully opening or closing because of a vacuum leak.

There is only one way the steam from the radiator could be coming in to the cab of the vehicle. That would be from the heater core, or the lines going to the heater core. If there is coolant/water leaking on that elbow on the firewall, it could either be that line that is leaking, or it could be leaking from the core and just dripping down to the elbow.
