Can plastic guards for top of Welsh baby crib rails be replaced?

There is one video that might help. Also the Kia Forums are a good source of information. There are two engines in the Sportage, a V6 and a straight 4, so that may be the difference in metal or plastic. There are only 2 bolts on the starter, but access is always hard unless you have ramps, a lift, or trolley jack and axle stands.

take it in to an accredited radiator shop for a coolant system pressure test
check for welsh plugs leaking , water pump seal leaking , holes in radiator cores or split top plastic tank. check color of sump oil and if it is a grey color it will be coolant in the supm

You mean frost plugs? Clean the outside thoroughly with degreaser and alcohol and then knock them in a little with a hammer, then silicone them. They are a domed steel plug, knocked into a slightly tapered hole.

Lots here on replacing them, Welsh Plugs, Welch Plugs, Core Plugs, Freeze Plugs :>)

one of the front impact sensors its located on the guard rail a front frame part. it sends a crash signal to control to set off air bag. but it wont set off air bag if not replaced.

You will need an adhesion promoter for the plastic part I think. Look at 3M 06396. It comes in little packets like you get at restaurants to wet wipe your fingers. This is for the plastic. For the painted metal, you need to use an alcohol wipe to clean the surface of wax, etc.

Try salvage yards.

1. Open the hood to your Pontiac Grand Am. Have the car keys on you, but not in the ignition and make sure the lights are in the "off" position.
   
2. Step 2 Locate the splash guard and the plastic push pins that hold it down. It runs along the entire front frame rail. Removing the entire splash guard will make it easier to to remove even one headlight on one particular side.
   
3. Step 3 Remove the pins by lifting up on the center of the pin. Pull it up about 1/4-inch and then pry the pin insert and pin out of the hole.
   
4. Step 4 Locate and remove the two-headlight assembly bolts on the the top of the headlight assembly. Use the ratchet and a socket to remove the bolts.
   
5. Step 5 Pull the headlight assembly forward by hand. Be careful not to scratch the lens of the assembly or scratch the paint on the front bumper.
   
6. Step 6 Unplug the wire from the back of the headlight that is blown out.
   
7. Step 7 Turn the headlight bezel counterclockwise (about 1/4 turn) until it releases the headlight from the back of the headlight assembly. Extract the old headlight and discard it.
   
8. Step 8 Insert the new headlight into the headlight assembly. Be careful not to touch the glass of the bulb. Handle it only from the bottom.
   
9. Step 9 Replace the bezel and turn 1/4 turn clockwise until it locks into place.
   
10. Step 10 Plug the wire back into the headlight and rest the assembly onto the bumper gently so you can turn on the lights to test and make sure the headlight it working properly.
    
11. Step 11 Insert the headlight assembly back into place. Replace and tighten the headlight assembly bolts.
    
12. Step 12 Put the splash guard into place and place the push pins into position. Insert the pin and its insert into the hole with the pin still in the "up" position. When the insert is seated flush to the splash guard in the hole, simply push the pin down to lock.
    

no-just make sure you remove the pin that secures the inner guide rail. The banana rail isn't secured on the head. If the inner guide rail breaks then you will have to remove the bottom front cover to replace it so be careful.

even u look on the other side of the brace u can stick a 15mm and extension and get the back bolt out. and the plastic lip under the bolt towards the front of the car i just broke that plastic lip off but theres a way u can get that plastic guard off by squezzing it
