Hello, I'd be happy to help you! Since you have a laser thermometer this should be fairly straightforward. There are two things these particular engines are notorious for: heater cores, and radiators. The coolant they use gells up if not changed regularly. What does the temperature guage show on the dash once it's had time to reach operating temperature?
Ok. When you get the chance take the laser thermometer and check as many places as possible on the core of the radiator, sometimes when they're restricted or clogged you can find a cold spot, that'll help us decide where we need to look.
You gave hose temperatures, not core temperatures, hose temperatures do not give you as accurate information. I am an ASE master certified technician, been doing this a long time. In any case that's fine, good luck.
Hi, my name is ***** ***** have a plugged heater core on this, and it is very common on these, this vehicle does not use the standard serpentine design on the heater core, it is more like a radiator, and debris collects in the bottom of the core and is not easily flushed out, we use a chemical flush on these, would you like the procedure for doing this?
