A leaking radiator can be repaired, but not with some sealant. In most cases if the radiator is leaking the very best thing to do is buy a new one and replace it. Unless you are not going to keep the car. If it has one leak it will develop more leaks over time. Plastic radiators can rarely be repaired.

This vehicle has an aluminum radiator with plastic tanks.If he is thinking of using some sort of cilicone sealer he is wasting his time.It will not hold pressure and you will end up overheating the engine and creating a bigger problem.New radiators are not expensive anymore and you can probaly get one at your local parts store for under 200 dollars.

I have a 2004 Saturn ION 3 QC, my husband has replaced the struts and cv joints with new seals and now there is a transmission fluid leak on the drivers side- did the seal not seat correctly?


That is a very strong possibility, however I think that your husband would have made certan that the seal was seated propperly. So all you can do is change the seal again. Make sure you inspect the cv shaft where the seal rides for any vissable damage sharp cut marks, dents or scrapes. Also lubricate the in side of the seal with some grease upon installation. Take care when slidding the cv shaft into place so no damage can occure to the seal. Good Luck, From Ernie @ RedDeer, Alberta, Canada.

Leaking radiator from engine cooling line on top of radiator. is there any way to re-seal?


Are you talking about the 2 inch water hose at the top ,or the overflow line about 1 half inch coming out of the radiator cap. If it is leaking from the radiator, replace the radiator, if it is coming out of the overflow, replace the radiator cap. If it is coming out of the top radiator hose then replace the hose

Replacing radiator 95 Jeep GC


No it is not difficult to replace a radiator it can be done with basic handtools I would not suggest a used radiator, if at all possible spend a little extra now and buy one with the best warranty (lifetime) available although with a new one you are looking at approx $250 plus coolant. Here is the proper procedure for replacment
Grand Cherokee
See Figures 9, 10 and 11
  1. Disconnect the negative battery cable.
  2. Open the radiator valve and drain the cooling system.
  3. Remove the fan and shroud assembly.
0900c152800a9917.jpgFig. 9: Radiator and condenser mounting
  1. If equipped, disconnect the automatic transmission cooling line quick-fit connections.
  2. Matchmark the upper radiator crossmember and adjust the crossmember to the left or right.
0900c152800a9918.jpgFig. 10: Radiator upper crossmember assembly
  1. Eight clips are used to retain a rubber seal to the body. Gently pry up the outboard clips (2 per side) until the rubber seal can be removed. Do not remove the seals entirely. Fold back the seal on both sides to access the grille opening reinforcement mounting bolts and remove the bolts.
  2. Remove the grille.
  3. Remove the upper brace bolt from each of the 2 radiator braces.
  4. Remove the crossmember-to-radiator mounting nuts.
  5. Working through the grille opening, remove the lower bracket bolt securing the lower part of the hood latch or hood latch cable from the crossmember.
  6. Lift the crossmember straight up and position it aside.
  7. If equipped with A/C, remove the 2 A/C condenser-to-radiator mounting bolts which also retain the side mounted rubber air seals.
  8. If not equipped with A/C, remove the bolts retaining the side mounted rubber air seals compressed between the radiator and crossmember.
Note the location of the air seals. To prevent overheating, they must be installed in their original position.
  1. Disconnect the coolant reservoir/overflow tank hose from the radiator.
  2. Disconnect the upper hose from the radiator.
  3. Carefully lift the radiator a slight amount and disconnect the lower hose from the radiator.
  4. Lift the radiator up and out of the engine compartment, take care not to scrape the fins or disturb the A/C condenser if equipped.
If equipped with an auxiliary automatic transmission oil cooler, use caution during radiator removal. The oil cooler lines are routed through a rubber air seal on the left side of the radiator. Do not cut or tear this seal.
To install:
0900c152800a9919.jpgFig. 11: Radiator alignment dowels
  1. Lower the radiator into the vehicle. Guide the alignment dowels into the hoses in the rubber air seals and then through the A/C support brackets, if equipped. Continue to guide the radiator through the rubber grommets located in the lower crossmember.
If equipped with A/C, the L-shaped brackets, located on the bottom of the condenser, must be positioned between the bottom of the rubber air seals and top of rubber grommets.
  1. Connect the lower radiator hose to the radiator.
  2. Connect the upper radiator hose to the radiator.
  3. If equipped with A/C, install the bolts condenser-to-radiator mounting bolts.
  4. If not equipped with A/C, install the rubber air seal retaining bolts.
  5. Connect the reservoir/overflow tank hose to the radiator.
  6. If the radiator-to-upper crossmember rubber insulators were removed, install them.
  7. Install the hood latch support bracket-to-lower frame crossmember bolt.
  8. Install the bolts securing the upper radiator crossmember to the body.
  9. Install the radiator-to-upper crossmember nuts.
  10. Install a bolt to each upper radiator brace.
  11. Install the grille.
  12. Position the rubber seal and push down on the clips until seated.
  13. If equipped, connect the transmission cooling lines.
  14. Install the fan shroud with the fan.
  15. Install the fan and shroud.
  16. Rotate the fan blades and ensure they do not interfere with the shroud and at least 1 inch (25mm) of clearance is allowed. Correct as necessary.
  17. Fill the cooling system.

Leaking rear seal on transmission


if you are talking about the seal at the rear of the tranny where the drive shaft goes into than it is fairly easy.
1.put something behind both tires so the vehicle does not try to roll away when you complete step 2.
2.take the drive shaft down.
3. take a flat head screw driver and a hammer.
4.take the screw driver and put it in the crack where the seal and tranny meet.
5.you will need to tap the screw driver into the crack until you can get a good grip on the seal with the screw driver.
6 you will need to pry out on the seal until you see it move.
7.do this all the way around until you can get the seal out.
8.make sure nothing is in the way of you putting in the new seal
9.put a little bit of tranny fluid on the new seal.
10 put the seal in place and lightly tap the seal. into the tranny.
11. put the drive shaft back together.
