Just about ready to lift the manifold but havent drained any coolant out yet as i cant get the bottom radiator hose off and do not have a drain plug fitted (aftermarket radiator)

Will draining the cooling from the top hose and heater hoses be enough or will this still leave water in the manifold and cause problems.

Thanks Chris

Draining the top hose won't do it. Not sure if the heater hoses would either. Have you thought about using the block drains to lower the coolant level?

Drivers side water temp. Sensor can be unscrewed and allow fluid to come out. I just did this to mine. Installed a polished Weiand manifold. Good luck.

stick a hose all the way down your radiator and pump it out... use one of those cheap 5$ drill pumps.

Yo...siphon bro....!

I think this is a good tip as my sensor stopped working so i can kill two birds with one stone.

Thanks

Glad I could help. When you buy a new sensor, get the right one. I didn't know there were different types = resistance. So your gauge reads correct. Just type in the search box water sensor, you'll get the info I got

Manifold finally removed

Couldn't get the temp sensor off so used a $5 siphon pump into the radiator and it worked a treat.

Now to clean everything up and start installing the new manifold...

Thanks for the input...

Were you able to get a socket on it? Usually there a bit stiff, but once the socket is on and with leverage, they come undone. Since yours does not work, might want to try again, before finishing up and topping off.

I use a suction hand pump, but yes, you have to at least drain the raditor.

Chris,
While the radiator is empty, why not use the opportunity to fit a drain plug to it. Any decent radiator repair shop should be able to do this in about ten minutes.

And I agree with daanbc to put some muscle onto that temp sender while the engine is waterless and fit the right one. Even if you can't get one right now, at least you will have "unfrozen" it so that it will be easy to remove when you get a new sender.

That's what 4 foot cheater pipes and guaranteed snapon sockets are for.

Without a drain plug, the syphon trick is the fastest, least messy method anyway.

Yup! A pipe always comes in handy as a cheap breaker bar.
