Gazzawu Posted December 11, 2005 Share Posted December 11, 2005 spark plugs is easy just make sure when ur removing the coolant hose from the throttle body that you catch the coolant before it all flows into your sparks plug leads. so lay loads and loads of paper towel over them before you disconnect them.

Eh......didn't have to do that on mine and I've read of others getting away with it on the N/A as well. Link to comment Share on other sites More sharing options...

I have changed my spark plugs loads of times and never seen a coolant hose in my throttle body,dont think i want one either.Water dont mix to well with air/fuel i've been told. :badidea: Link to comment Share on other sites More sharing options...

The reason why its more difficult to change plugs on the NA is because you cannot gain access to 3rd, 4th and 5th plugs unless u remove the throttle body. Some stupid reason toyota decided to run coolant through the throttle body. hence to remove the TB you have to disconnect the coolant hoses which run through them. Look at the pdf on how to change spark plugs on the mkiv.com link Link to comment Share on other sites More sharing options...
