Low Coolant Temps in Your Jeep?
Alex here, taking a quick break from crafting tire covers to share something important. You know those days when your Jeep's trying to tell you something but you're not sure what? Let me tell you about my adventure with a '95 4.0L that taught me some valuable lessons about engine temps.
The Problem:
Recently faced a tricky situation with my Jeep - heater wasn't cooking me like it used to, and the temp gauge barely moved past the second mark. Sound familiar?
What I Discovered:
After replacing the thermostat (and making a few rookie mistakes), here's what I learned:
The Real Issue? Air in the System!
- Most DIYers (including myself!) rush the bleeding process
- Proper bleeding can take up to an hour (yes, really!)
- Both heater hoses should be equally hot
Pro Tips from My Experience:
- Get a coolant funnel system (best $20 I've spent!)
- Keep the funnel filled while bleeding
- Wait for BOTH radiator hoses to get hot
- Don't trust the gauge alone - get an IR temp reader
Common Misconceptions:
- Head gasket leaks usually cause high temps, not low
- Weak heat doesn't always mean a clogged heater core
- New thermostat doesn't guarantee proper temps
The Solution That Worked:
Take your time with the bleeding process. I mean really take your time. Let the engine warm up completely with the funnel attached. Those air bubbles need patience to work their way out!
Keep it Cool, Alex
