I dropped the motor as far as possible, took off all the hoses and the electric connector, disconnected the fuel lines, etc.

I would say changing the tank on my '02 Cab was one of the most trying DIY's in my 40+ years of shade tree mechanics.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

I had to replace my water pump so I thought I'd go ahead and replace the coolant tank. It was challenging to say the least. I dropped the motor as far as possible, took off all the hoses and the electric connector, disconnected the fuel lines, etc. I did everything I could to give me room to wiggle the tank out. No luck!!!! I had the tank off its mount but no amount of wiggling and jiggling would get it out. I think I'd next an extra 1/2" on the side to slide it out. I've got the sheet metal of the body on the left side and the engine on the right side. I just can't see how to get it slide out. What am I missing? I read that it was difficult but doable. BTW, I ended up just reinstalling the old tank. It's not leaking and I wanted to wrap up getting water pump installed. At some point in the future, I'd like to replace it.

POST 2Original post

It's not easy. I changed mine out this past summer and said words I hadn't used since I was in the navy 46 years ago.

POST 3Original post

I would say changing the tank on my '02 Cab was one of the most trying DIY's in my 40+ years of shade tree mechanics. You have to keep at it, take breaks, and be patient. Good luck.

POST 4Original post

I have an MK-I C2, so the tank is a bit different. It was a real pain to remove and replace. I wiggled and turned and wiggled and turned then eventually it came free. Same thing for installing the new one. You have to get the angle just right. Try reaching underneath and removing the coolant level sensor first. Also, buy a replacement sensor because you're likely to break it and it's not very expensive. Also, cursing helps.

POST 5 / ORIGINAL POSTEROriginal post

Well, the good news is, the old tank isn't leaking so I'm not going to attempt it again unless it does. I'm wondering if I take out the motor mounts completely if I can nudged the engine over to the right just a bit. I just need about a half an inch. MERRY CHRISTMAS!!!!!!!!!!!! Dave
