#87 of 88 97 quest heater/loosing coolant by jarman

Oct 08, 2012 (7:33 am)

hi i was wondering if you could help me out here i have a 97 quest with the 3.0,it has been leaking coolant for a year now,when it steams it comes from under the hood and wheel wells.i suspect the heater core or hose but cant get my big head in there to see anything!i have heard about plenums and such but i guess my question is this,is there an easier way to diagnose the problem myself?pressure test maybe?and just how difficult to replace the heater core in the quest?the water levels stays at a level where it will not overheat unless sitting at a light for awhile,we add some coolant about every few weeks.it does not steam every time but definiatly has a wicked smell.this is a terrific vehicle and it does have sentimental value.thanx for any tips or advice or help i may receive.

When it comes to leaks I tend to leave it all to the mechanics. These things are very difficult to trace unless the problem is right there in front of your eyes. As a matter of fact my van has had a slight oil leak for quite some time that not even my mechanic has been able to trace.
Usually a dye is added to the coolant in order to trace the leak/leaks and then take it from there.
