Installation Guide

  1. Ensure the engine is completely cool before beginning any work. Disconnect the battery to prevent accidental starting.
  2. Drain the cooling system by opening the drain plug or removing the lower hose. Collect coolant in a suitable container.
  3. Locate the thermostat housing on your Volvo Penta engine. It is typically mounted on the cylinder head or block.
  4. Remove the bolts or clamps securing the thermostat housing cover. Carefully lift off the cover.
  5. Extract the old thermostat from its seat. Note the orientation of the thermostat before removal.
  6. Clean the mating surfaces of the housing and cover thoroughly, removing all old gasket material and debris.
  7. Install the new thermostat in the correct orientation (spring side typically faces the engine block). Ensure it seats properly.
  8. Place a new gasket or O-ring on the housing if included in the kit. Apply a thin layer of sealant if recommended by the manufacturer.
  9. Reinstall the thermostat housing cover and tighten the bolts evenly to the manufacturer's specified torque.
  10. Refill the cooling system with the correct type and mixture of coolant as specified in your engine manual.
  11. Reconnect the battery and start the engine. Allow it to reach operating temperature while checking for leaks around the thermostat housing.
  12. Check coolant level after the engine has cooled and top off if necessary. Verify proper thermostat operation by monitoring engine temperature.

Troubleshooting & FAQ

Q: How do I know if my thermostat needs replacement?
A: Common signs include engine overheating, running too cool (not reaching normal operating temperature), erratic temperature gauge readings, or coolant leaks around the thermostat housing. If your engine takes longer than usual to warm up or runs hotter than normal, the thermostat may be stuck open or closed.

Q: Will this thermostat fit my specific Volvo Penta engine model?
A: This thermostat is designed to fit MD2, MD6A, MD6B, MD7A, MD7B, AQ120, AQ125, AQ140, and BB140 models. Cross-reference your current part number (875796 or 833366) with our listing and verify the physical appearance matches your original component before ordering.

Q: How often should I replace my marine engine thermostat?
A: Thermostats should be inspected during routine cooling system maintenance and typically replaced every 3–5 years or according to your engine manufacturer's service schedule. If you experience cooling system issues or the thermostat shows signs of corrosion or damage, replace it immediately regardless of age.

A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

Q: How fast do you ship and how much does it cost?
A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.

Q: What is your warranty and return policy?
A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details.

The kid and I both love this book
Format: Hardcover
I am so enamored with the illustrator of this book that I've taken to buying almost everything he does. The illustrations here are so cute and playful! My daughter wants to read this almost every single day. She loves to point out the bugs on the different page and we make up stories about them. She can now recognize so many bugs we when go outside and is really excited to see them in real life! She laughs at the antics of the ladybug on each page and loves that there are different animals hidden in with the bugs. Really can't say enough good things about this book. My only caution is that there aren't really a lot of words, so if you aren't comfortable ad-libbing or making up stories you may find it a bit boring. But if you make it interactive it's really fun!

Greatest book on the planet
Format: Board book
This book was purchased for me as a baby shower gift. My daughter is obsessed with this book. We have read it so much that our first copy has seen some damage (the book is sturdy, the damage is our fault). I had to get another copy just to keep forever. I will also be purchasing the hard cover book to keep in my collection to have forever. The illustration is brilliant, we love Oscar, the writing itself is so fun. I love that it encourages exploration, play, as well as education. 10/10 - this is our favorite childrens book ever. We read it maybe 30 times a day.

Cute Rhymes and wonderful info
Format: Board book, Format: Board book
This book is super cute and makes bugs interesting with it's colorful pages and different big varieties. The book rhymes throughout the pages and it's so cute and almost reminds me of song that could have sung by the "Animaniacs" (my age is showing lol). In one of the pics I show the cover damaged but that's from my son chewing on the book. Just because it's a board book doesn't meant it's exempt from damage, just makes it last a little longer than a paperback. I also REALLY like that there is a page that lists the bugs seen along with their names which is helpful in teaching your little one! My son enjoyed this beautiful book. :)

Perfect size, cute illustrations and words
Format: Board book
My toddler girl is super into bugs right now. This book was suggested alongside a bunch of other bug books I purchased (Maisy’s Nature Walk, Bugs, All Because a Little Bug Went Kachoo, The Lonely Firefly, A Good Place). What a great find! It’s the perfect board book size for me to hold or for my toddler to hold. The illustrations are darling and the words simple enough that my almost 2 year old has pages memorized. When she sees a picture she’ll spout out the words. I appreciate the back page with the illustration of all bugs with their names because lord knows my toddler asks me time and time again “what’s that?!” and mommy is fresh out of lies. My insect knowledge is clearly not as profound as my daughter.
