It will only be a problem if you need to un-fog your windshield in the cold or rain.
To defog or defrost requires heat.

 

Find a different / better mechanic friend and get that thing swapped! It would be super annoying every time the marine layer / fog rolls through and you can't see until it goes away (if it does, by the afternoon...).

Years back I did one in the Jetta that I had at the time - huge PITA and took ~10 hours over the course of a long weekend, but the dealership wanted $800 as a starting value. Unless it's a proper race car, you're going to be quite inconvenienced by not having it hooked up properly.

 

 

Can you share what size coupler/hose did you use?
is it 5/8 and 3/4?
Thank You

You won't get a response.

 

damn. Anyone else bypasses their heater core?

 

A friend has done it on a couple of old cars he's restored but he only drives them in summer and never when it's wet out so he has no concerns about needing heat or defogging.
