Quick summary

Mission: help it stay cool.

Symptoms / reason for repair

Thermostat needs to be trusted before longer drives.
These parts are old and/or the last mechanic REALLY didn't know what he was doing.
Thermostats are super duper cheap. If in doubt, change it out.
This is a good step-one repair before deeper troubleshooting of the cooling system.

Parts & supplies

Thermostat: correct temperature rating for the 2.2L Turbo. Always check.
Thermostat gasket: replace every time.
Coolant: enough to top off after the job is done.
Hose clamps: optional here, but old clamps love to be a PITA.
Shop towels: always many.
Catch pan: coolant can poison animals and people. Catch it, clean spills, and dispose of it safely.
Tools

What I’m using.

Socket set and ratchet
Wrenches
Screwdriver or clamp tool
Gasket scraper or plastic scraper
Drain pan
Funnel
Gloves
Flashlight for dramatic underhood staring
Note to self: take photos before removing anything.
Step-by-step

The actual plan.

Step 01

Let everything cool completely.

Do not open the cooling system hot. Pressurized hot coolant is not cool.

Step 02

Disconnect the battery.

Probably didn't need to, but it's a good habit.

Step 03

Place a drain pan under the work area.

Some coolant may escape. A cat litter pan works great in a pinch.

Step 04

Follow the upper radiator hose to the thermostat housing.

The housing should be where the upper hose meets the engine. Take photos before loosening anything. Whoops.

Step 05

Remove the hose and housing bolts.

Work slowly. If something feels stuck, take a beat before applying full noodle-arm strength.

Step 06

Remove the old thermostat.

Note the orientation before pulling it out. The new one needs to sit the same way, unless the prior person installed it wrong.

Step 07

Clean the mating surfaces.

Old gasket material needs to come off carefully. The goal is clean and smooth, not “I attacked this with a chisel.” A clean razor blade on the surfaces should do the trick.

Step 08

Install the new thermostat and gasket.

Seat the thermostat correctly, place the gasket, and reinstall the housing evenly.

Step 09

Refill coolant and check for leaks.

Top off the system, start it, watch the temperature, and inspect the housing for leaks.

Step 10

Celebrate responsibly.

If it holds temperature and doesn’t leak, that is a wagon win. Small victory. Big morale boost. If the problem persists, sad trombone, you're back to testing. Me!

Photo notes

.....and voila!

What went sideways?

Honestly, this one was super easy. Nothing went wrong. It took me only about 30 minutes to complete the job.

Final result

Unfortunately, the thermostat wasn't the problem. I am still having the overheating issue and the stall out. The next step is to borrow some tools from AutoZone and do some testing.

The wagon gets another win.
