need help--HVAC Heater Control Valve problem
 

hi my name is adhi from Indonesia
I have a problem with HVAC Heater Control Valve / part no : 92857457303
I have a water leaking in the heater valve problem pic and video attached
since it hard to find the parts in Indonesia is it safe if I blocked the line from each pipe?

Sorry for my English :)

Heater valve porsche 986 leaking - YouTube

Logic would say with the heater valve at full closed psoition it would be cutting off flow just like you are proposing to do manually, by capping each pipe. The cabin heater is a sub component of the engine cooling system, and engine cooling is not dependent on the cabin heating system. I would say it will affect nothing but the fact you wont have a cabin heater...

Thanks for the answer :)

Ini this web : Porsche 986 996 TIP transmission cooler control Valve : Amazon.com : Automotive

Says its a Control Valve for Transmission Cooler not for the cabin cooler
So is it safe to block the pipe?

I've always heard that heat is the worst thing for a auto trans and considering the expense of rebuilding your tip I'd try to keep things working as Porsche wanted. You may be able to diagnos/repair it with an epoxy or maybe it's leaking at one of the hose connections. See if you can find the source before disassembling it. Sometimes just adjusting the hose clamps can stop it. Also, these cars are very sensitive to air pockets in the cooling system. I'd suggest you read all you can about coolant flushing etc. By the way, your English is excellent. I also enjoyed one of you scooter rides! High risk compared to where I live.

Only if you want to totally destroy and expensive Tiptronic transmission.......

could he put a solid pipe in there to replace the vacuum operated valve JFP?

I already remove the HVAC and it seems leaking from the Hvac itself
And I asked the price at porsche indonesia cost me about $144 and labor cost $204
Compare to mercedes W201 Hvac(same model) $69 but difficult to find in Indonesia :(

Is there any way to repair the Hvac (glue or something?) or I have to buy the new one?

@woodsman ;how do you know I m a scooter ride :) :) :)

You don't want to do that as the trans will not operate in the expected temp range; you need the valve to "throttle" the system.

These valves are simply not worth trying to fix, as soon as you stop one leak, they start to leak elsewhere. Get a new one and be done with it.............

I'd follow JFP"s advice 777 as he owns a garage that repairs Porsche's and other exotics.
I watched one of your UTUBE videos- you toured around the streets on a scooter.

If you buy the HVAC system from Porsche store, then definitely, you have to pay a hefty amount. Hence, it would be very intellect of you, if you hire some professional HVAC repair guy who would do the job at an affordable rate or buy the same from some western country where you would get the product at a cheap rate.
