Hi,

I started this thread in 2nd gen section but had no success. So I try this section because there is potentially more engine builders that have face this problem.

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 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?

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

 

BTW it's for a 13B-RE engine with TII rotor housing.

 

I used a socket, and a hammer, the trick was using the hammer sideways to hammer them in. It is not a quick process, that is for sure.

 

Yeah, just take your time. It's going to be a tight squeeze but it'll work out. Make sure to use some gray Permatex also...
