Coolant leak was created by Cameo543
Morning All. New to Jimny ownership having recently acquired an unloved 2006 convertible M13AA. Recently removed and replaced the throttle body for cleaning and to get to the bottom of a throttle body position sensor fault code. In removing some water pipes, I must have disturbed a failing metal pipe union that now has a pin prick hole in it that delivers a stream of coolant across the engine bay. Bit stuck on how to proceed. Can I solder it for a temporary fix and what part of the engine is this for eventual replacement?

Welcome to the forum. That appears to be the thermostat housing. No reason why it won't braze unless the heat turns it into a puddle. I'd be inclined to remove the housing to conduct the repair.

Thanks. With the throttle body and air pipes out the way access isn’t too bad. I’ve cleaned the area to bare metal and it is just one pin sized hole. Would a high temperature soldering iron get anywhere. Not sure I’m confident brazing first time on this. Maybe time to call in professionals

A small blob of chemical metal will be the easiest solution.
Just smear it across when it's cold and not leaking out. If you have to drain the coolant and clean it with brake cleaner, so be it.

You said it yourself," it's failing" and the pin prick wont be the only problem area. Pipes like that are a factory fit and not a practical DIY replacement. As kirkynut suggested, chemical metal is a practical short term fix that can be done in situ as heat is not required but cleaning the area thoroughly is a must. Be prepared to find other holes as you do the cleaning though.

Thanks for the replies. What started as a bad throttle position sensor has turned into a bit of a nightmare. Leak, attempt at brazing which failed. Removed throttle body, intake manifold and everything else to get thermostat housing off. I now find the flange on the spindle that connects the thermostat housing to the water pump assembly is corroded 70% of its perimeter (see pics). Could this be welded? It is just thin steel. I assume that this isn’t a replacement part that can be sourced from anywhere. I suspect whoever had this in the past has been cooling it with tap water!!

In no particular order.
How much is a s/hand housing?
How much is a new housing?
Do you have a local machine shop who can repair it? Forget about the 2 steel pipes, they are toast. They need to be machined out and replaced with new made to measure pipes. Suzuki will only supply a complete housing with pipes and yes that will probably cost more than a new one.

Thanks for the quick reply. I would be happy to buy a new housing if they can be still sourced from Suzuki. Will visit our local dealer tomorrow. After that will try the scrapyard etc.

Thanks, I’ll pm you the VIN. It’s a wacky Spanish Santana one that never seems to show up on the standard parts site.
