I just replaced my Coolant expansion tank..As I understand a lot of these had problems with the return line nipple cracking off as was this case...

Temporary Fix:




New tank;

 

I had that same exact problem on mine. It's amazing how much the dealer gets for that little plastic tank, isn't it?

 

Cleaned the engine too..

 

wow! how did you clean it? what did you use?

 

I used regular Car soap/shampoo and used a lawn/garden sprayer to dispense it all over the engine...Then rinse well with hose and nozzle pressure...I then took off engine cover and Blow dried with Leaf blower and Compressed air and then let sun dry for an hour or two

 

Then I sprayed the entire engine/parts and hoses with this F21 stuff..Not greasy and it dries shiney..

 

Yes, ridiculous

List: $192.21 What they would have charge if bought out right.

Net: $131.26 Means what theycharge if it's under waranty and they install.

 

is there anything i should cover up to keep water off of? and what is a "law sprayer"?

 

LOL..Lawn Sprayer (ortho dial a sprayer)..Sorry about that..LOL


Good question..I cover the brake reservoir with a sandwitch baggieand avoid shoot water directly at the Altenator

 

Wow, I thought it was only my cat that little nipple broke, must be a common problem, I dont get it though, there is little pressure in that nipple why it breaks?

 

It's a thinner plastic piece that, especially in areas that have cold winters, has temp changes from extreme cold to ultra hot... That would tend to make it brittle over time. Then, add in the flex of the motor that pulls on the hose and wiggles it... It's only a matter of time before it breaks. It's a poor design in my opinion.

 

Thats the best explanation so far, I can't agree more, a bad design. cost $150 bucks for replacement, I might just do some modification by adding a copper tubing to replace that plastic tank.
