Repairs to Our '88 Itasca
When we were on the road in Wyoming last Sept. the radiator decided it wanted to leak. Did some temporary repairs but then noticed the carb was starting to leak fuel.
So after recovering from several surgeries I decided to tackle the MH. Pulled the radiator and carb. Bought a new radiator ($633) that was close but no cigar, so had a new larger 4 row core ($443) installed between the old tanks. The old core was 4 row but only about 1/4" wide tubes, new core must have 3/8" or larger tubes.
Took the carb to Rod's Carbs here in Phoenix and had him rebuilt the old Quadrajet. New float, choke coil, throttle shaft bushings, etc. Rod's is known for doing good work and the price was good at $195. They have an engine in the shop that they run these on after they are done with the bench testing.
Changed the trans fluid and filter while it is down.
Also converted the a/c system to 134a from Freeze 12. Good thing I had to change the compressor oil as there was only 1/2 ounce in it, supposed to be 5 ounces. I cleaned all the bugs out of the condenser and straightened any bent fins.
The guys at the a/c shop I buy my parts at said 134a is going to be scarce this year and the price has already started to go up. They are at $12 a can my cost. I bought a case of 12 cans at Sam's for $83.
I just about have the area surrounding the radiator insulated with Reflix insulation. Don't know for sure this product will stand up so it is an experiment. Hope it cuts down some of the fan noise when the clutch is engaged.
Tomorrow will be carb install and hopefuly the radiator also. May not get it all done tomorrow as I want to rewire the condensor fans to come on with the a/c or high coolant temperature and also have a manual override switch on the dash. The fans did not work when we bought it so I wired them to a dash switch but now want to change it.
I have left the fans running on purpose when we stop for fuel or make a quick store run, etc, the airflow seems to help cool the engine and carb.
Well, time to see if I can get to sleep now.
Drive careful and have fun!
