I’m experiencing a frustrating issue with my Chevrolet Silverado. Recently, I noticed a coolant leak on the passenger side, and I’m not sure what the cause might be or how to fix it. Here’s what I’ve gathered so far:

Symptoms:

  • Puddles of coolant forming on the ground under the passenger side.
  • Temperature gauge indicating slightly higher than normal after driving.

What I’ve Checked:

  • I inspected the hoses, but they seem intact.
  • No visible signs of leaks from the radiator.

Questions:

  • Has anyone else encountered a similar issue?
  • What are some common causes for a coolant leak specifically on the passenger side?
  • Any DIY fixes or tips before I take it to a mechanic?

I appreciate any insights or experiences you can share. This community has always been helpful, and I’m hoping to get this resolved without breaking the bank!

I had a similar issue with my Silverado! Check the upper and lower hoses on the passenger side; they’re often the culprits. Also, the radiator often leaks from the seams, especially if it’s old.

I’ve had my radiator leak too! It’s good to inspect it closely for any cracks. If it’s bad, a full replacement might be needed.

4

Don’t forget about the water pump! It can sometimes leak coolant out from the weep hole. I’ve seen it happen on a few Silverados in my family.

5

Great point about the water pump! Did you find it hard to replace when it leaked? Any tips?

6

I’ve replaced my water pump before; it was surprisingly straightforward! Just make sure to get a good gasket, or you’ll have more leaks.

7

Not hard at all, especially with some online guides. Better to tackle it before it gets worse!

8

Sometimes it could just be a loose clamp on the hoses! I learned this the hard way after replacing my entire cooling system.

Loose clamps? You’re kidding! All that effort for something so simple? Should’ve checked that first. Good tip!

10

I’m curious, does anyone else notice that passenger side leaks are more common than driver’s side on Silverados? Just an observation I’ve made.

11

I hadn’t thought about that! It could be due to the way the engine is oriented.

12

Pressure testing? I thought that was only for tire issues! Learning new things here. Thanks!

I once fixed my leak with duct tape and a prayer. Definitely wouldn’t recommend that though! :joy:

14

Haha, desperate times call for desperate measures! But in all seriousness, getting the right parts is crucial.

15

Thanks for all the advice, everyone! I’m feeling motivated to tackle this head-on. I’ll make sure to check everything everyone has mentioned!

I noticed unusual engine temperatures before I found a puddle under my Silverado. It could definitely be a coolant leak. Check for any signs of fluid around the hoses!

17

That’s a great point! Also, dashboard warning lights can be an early indicator. Keep an eye out for any warning messages.

18

If you’re seeing puddles under the passenger side, it might be a sign of a leaking heater core. It’s worth getting checked out before it causes more damage.

My Silverado had similar issues! The coolant leak caused overheating, which was really stressful. I recommend checking the radiator and hoses carefully!

That’s true, but sometimes it’s just a small hose that needs replacing. Don’t jump to conclusions too fast!
