Can anyone tell me what kind of spark plugs I should use to replace in my GMC 302,, 211. It said waterproof?

Hey all, I finally decyphered the manual and through process of ellimination I discovered that there was not evough brke fluid in the master cylinder to activate the air assist. after filling then recaping the master cylinder resv. it has worked without problem. Now I have go to do a...

Should the vent plug be reattached? or is it OK the way it is.

I am also have break problems. It seemed to be the least of my worries when I first got the truck. In fact it stopped pretty well up until a few days ago. There is plenty of air pressure. The manual says that if they feel mushy then you need to bleed the system. My question is when I opened...

Thank you. Wow you guys can come up with the answers to almost anything.

Good morning Gunboy, Can you tell me were you got the canvas top for the M211 you owned? Is there more than one place. Anyone local? Thanks

Thanks Marti, I will do just that. I am still feeling my way around the truck. I have a manual on my computer but haven't printed it out to take down to the truck. As I read, I generally have more questions than answers. You folks have really been great help. I hope I can return the favor one...

It has a tailgate but it seems a little short width wise, it also has a step that swings out when released. I'll take a pic tonight and post it.

No I don't, but it won't be hard to get a few more. I will see if I can get some tonight. The top looks like it was welded in a few places like around the top, back and sides. It was used as a fire brush truck so I think they worked on it a bit. I really want to put a rag top back on but I will...

I was thinking the same thing. Right now it sounds like a diesel. I wouldn't mind but the exhaust flowing into the cab is more that I care handle.

Ya, I was thinking of doing the same thing. I need to get it off and take a good look at it. Thanks.

Thanks I'll try to keep my keyboard moisture level set to low speed!

Thanks again. Does anyone know what aftermarket muffler replaces m211

Thanks. I will start there. I have learned that shifting properly helps when you know a hill is coming. .I know its not a fast truck but I think it should give me a little more power that it is presently. Also does anyone know what type of muffler I need to get in aftermarket to replace this one...

Thanks, I'm going to get it checked next week.

Thanks, I don't have very much experience with engines. It seems to run and idle fine. (I checked the oil and it looks fine the trans fluid is also clean and pink. The engine has 14,000 miles oil looks very clean.. Came from a fire comapny in Maryland. MAybe once I run more fuel through it will...

Hey all, If anyone can help would appeaciate it. I and looking for two things I just received my GMC m211. I would like to know if there is anything I can do to boost engine performance (I have to put it in low 1 just to get it up a moderate hill.) Also I would like to get the rough shifting to...

Thank you very much for the id info. JackG

I know this is a real newbee question but how do you find or where do you find the exterior markings for your vehicle (m-211). For example the yellow circle with numbers as well as other truck markings. Also, how can I get a little more power out of my engine. It seems to be a little lacking on...
