Special tool

[kk lowrider]

Is there a speciel tool I can use to take the square plug out of my intake manifold on my volvo 4.3 . I have no room for a wrench it needs to be a socket of some sorts to drain my intake. Any help would be appreciated.

Ayuh,.... A standard 12-point socket will fit...

Re: Special tool

Metric sockets work better than SAE sockets for that.

You guys use metric south of the border ? What next, Robertson screwdrivers ?

Re: Special tool

An 8-point socket would probably grab better than a 12-point.

Re: Special tool

Maybe so but everyone has 12 pt. 8 pt. is not a common socket unless you are a plumber.

This is for Cr2K;

Sounds like good advice to change impeller before it craps out but how often and under what conditions? Pulling the lower unit on my Mariner is a bear.

Thanks

Check it every year when you winterize. If it's still solid without missing pieces, it's still good. If during the season, your motors running hot, the impeller is a possible cause. With an open cooling system, the more particles in the water, the more wear on the impeller. Don't know for sure, but I bet Cr2K learned this from experience, as he seems pretty passionate about sharing this valuable knowledge. I, on the other hand, had the benefit of being taught this.

Safe and happy boating always!!!

Not entirely true. I don't want to split hairs, but if the vanes are still on, give them a slight pull, like you're trying to tear one off. If it starts to separate, replace it. Also, they can look good before winterizing, but get brittle during the cold weather. Then on the first start of the season, break into pieces. If you're going to take the time to get into it to look at it, just replace it. They are a seasonal/hour rated change. Not a run it until it breaks item. They're pretty cheap for a once a year replacement.

Every year! Wow! I know you and veritas honus are right. Don't want the pump to crap out anytime but I am not looking forward to dropping the lower unit every year. I have done it a least 5 times in the last 3 years. Twice to replace the impeller (one worn out the other damanged by sediment intake) and 3 times to correct my install mistakes. I will definitely do it in the warmer months.

Thanks for the input.

Re: Special tool

It always seemed easier & cheaper to me to just do it once a year with the spring service, but then again , it was on an O/B...not an I/O.

Lower unit lube, impeller, propshaft seal, sparkplugs, fuel filter, grease trailer bearings. 3 hours work then on the water. Best part of the deal? My marine mechanic did the work. . It was cheaper for me to be at work while he worked on the boat properly. Usually $150 per year, but if you DIY, it's much cheaper.

Every automotive and truck engine I've run into uses four point plugs in the engine blocks, i.e. coolant and oil.
