Engine Size: 4.3
My mechanic has confirmed that I need replace my evaporator core. I do understand that likely I have to go through dash to get it. My mechanic said it will take about 7 hours and he could remove it through engine and not dash. Would anybody know for sure if this is true?
It's about a half hour job - split the case underhood and pry it apart- no need to remove either half- meerly have someone hold it apart and another hand to pull it out through the opening...reverse the procedure to insert new one ..remove all the bolts that hold the driver's side of case to the firewall and other half of case. Oh, and be careful not to crack it up to much- that old plastic gets really brittle.
If it takes seven hours, you need a new mechanic-- he must have a double boat payment this month!
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
Lol, That's what I thought, he is always over exaggerating to make money. He charge me over $1100 to do this job. I guess i do have to remove coolant reservoir and box that sits on for clearance huh? Lastly, should I replace accumulator? He said "I should since he had it off for a while and let air in it". I just brought this accumulator. Thanks.
