I ran over a a large piece of concrete in wish it scrapped the bottom I my vehicle leading to radiator fluid leaking out. The leak seems to be coming from a plastic piece that goes around the radiator...


there are two screws on the sides of the that plastic plate (it helps to guide air through the radiator) and you should be able to see where the damage is. you should be able to replace the radiator.

How to replace the radiator thermostat


There will be a big hose that goes from the top of the radiator to the engine. The thermostat is under the housing piece where the hose connects to the engine. Make sure the car is cold. Do not work on this when the car is hot or even warm.
The coolant is under pressure and will spray on you even when warm.
Remove the radiator cap, partially drain down the coolant into a bucket by opening the pitcock at the bottom of the radiator so you don't spill too much during the replacement of the thermostat.
Next remove the top radiator hose by looseneing the hose clamps. There will be some coolant still in the hose and it will spill out. Then remove the housing piece that the hose was connected to on the engine. The thermostat will be sitting right under it. Pop it out, replace the thermostat along with a new gasket too. I like to use a little high tempurature automotive silicone on the gasket. If you do use silicone, just use a tiny bit so the excess doesn't squeeze out and get into the new thermostat. Replace the radiator hose making sure all the connections are good and tight. Top the radiator back up with coolant and you're ready to go.

I recently replaced my radiator as it was leaking along the intire top connection. i replaced the stock number with a alluminium welded radiator and it worked fine, however, today after about 3 or so...


Depending on what area of teh country you are in, your elevation level actually helps decide the amount of pressure in the cooling system. I would suggest replacing the radiator cap, and installing a lower temperature thermostat in the vehicle. Also, take a minute and flush the cooling system completely, making sure it is completely clean.
