Roof A/C

[Tom and Pam Brown]

Cleaned the coils on the roof A/C today it had not been performing like I thought it should lately.

Used foaming coil cleaner from H/D at you would not believe the crud that came out when I rinsed.

Just a heads up to others this may need to be done to ensure efficient operation.

I wonder if that foam would clean the radiator?  

I was just up on the roof cleaning the ACs. The units we have have a plastic compartment for the front part of the AC, where the air passes thru the exchanger to cool the air. There were numerous screws missing creating a gap where outside air was entering the system. I replaced the missing screws and then used packing tape to positivily seal the small gap remaining. Will let you know how it works next trip.

Sean,

I personally have used the foam on my radiator on numerous vehicles and it works great.

[Sean Donohue]

What is it called? And you have used it on the Cat engine radiator?

[Tom and Pam Brown]

Sean,

It is called A/C safe and I purchased it at home depot.

Hope that helps.
