Hi



I'm preparing to block the coolant passages on the rotor housing. The engine is already in the car and I don't want to remove it. I would like to know the best way to block theses. I have a 13B-RE engine with TII rotor housing.



I know that you can put 20mm freeze plug. I have already tried to install freeze plug last summer but the shock tower was to close to hammer it enough hard to squeze the freeze plug in the hole. I would like to know how do you process when the engine is still in the car? Is it doable?



Another alternative would be to use 1/2 npt plugs but they need to be tapped and that would probably create debris in the coolant system. Could you just drain the system a few times to make sure that the system is clean?



Thanks,



Alex

Tape a length of small diameter tubing into the end of the shop vac hose. Maybe 1/2" ID. Clamp that tube end in place beside the hole to be tapped. Turn on the shop vac, and tap the hole. Little or no debris in the system. No problems at all doing this.
