My heater core is leaking. Pep Boys wants $1400 to replace it or $250 to bypass it. Bypassing seems the way to go because I live in Florida and don't use the heater anyway. But I'd like to try doing it myself to save even more money.

Here are my questions: how hard is this procedure and how long would it take? Where exactly is the heater core located? Do I need ramps to get under the care to access it? What extra tools/parts would I need (e.g. extra hosing components or the like)?

I haven't found enough details about the procedure yet to feel confident doing this, so any guidance from some people with experience would be great.

The heater core itself is the biggest bitch of any part on this car to get at. Bypassing it isn't worth 250$ though. Look behind your engine, its the two 3/4 inch hoses going into the firewall. Pull em off the firewall, put a brass barbed fitting to connect them. Make sure you burp it then top off your coolant and you're set to go until it freezes. Much easier to get at the hoses if you pull out the battery, and putting an ice cream bucket or something beneath them is good to catch the gallon or so of coolant that will come out.

I did it! Bypassed the heater core and it wasn't too much trouble. I only have one question now. The mechanic mentioned there being something gooey in the cooling circuit (I think he said it was in the heater core but I'm not sure). He recommended flushing the system. I'm wondering if this is really necessary. I replaced the radiator a few weeks ago and it therefore has new coolant. I've also had to put new coolant in because of the leak that I just fixed. So is there any good reason to flush the system at this point?

What could "gooey stuff" do anyway? Cause another leak?

He was probably giving it one last ditch effort to get some cash out of you. Unless you have symptoms that would lead to you flushing it I wouldn't bother. That is, as long as you put in the correct coolant and never added stop leak to it.
