Hello everyone I’m working on my 2000 S-type 4L I have a coolant leak coming from top of the engine. I have already replaced the thermostat housing and water pump and it is dry in front of the engine. It’s not the expansion tank that is dry. It gushes out when I pressure the system to 1 bar, before I start ripping into the top of the engine any suggestions or has someone seen this before?

 

The leak is most likely from the heater return hose under the inlet manifold.

Remove the inlet manifold to replace the hose.

 

Thanks I will do that and report the findings.

 

I finally got around to removing the intake and found that nasty hose that was leaking. The part that transitions from the large diameter to smaller had unglued. Found a replacement on Amazon PN NRA3976AA

While I have the intake off I will replace gaskets both upper and lower. I have the flat gasket for the throttle body to coolant manifold but I’m looking for the prong that goes from the coolant manifold to intake, anyone know what that is?

 

Perfect timing on this post. I think the same hose blew up on me today. Either that or I finally burnt the head gasket on my 2002 4.0. Getting a lot of coolant loss and stream from this same area. Will look into maybe this weekend or next and find out what’s going on.

 

Hopefully it’s just the hose, better than a head gasket but you do have to remove the intake. In Arizona I’m always leery about Messi g with anything plastic as it becomes brittle and breaks easily especially the electrical connectors.

 

 

It’s not difficult just a bit tedious. You will have to take off the thermostat housing to be able to slide it forward. Of course be careful with the connectors, my are brittle and break easily. You can you will have to disconnect all the injector connectors but can leave them in the intake. You will disconnect the fuel line going to the fuel manifold.

 

Don't forget the vacuum elbow below the manifold, now's the time for a new one!

 

Okay replaced the thermostat and water pump a few months back so that won’t be difficult but is a special tool needed to disconnect the fuel line?

 

About to find out if I'm in over my head. The throttle body looks like its going to be fun. So does the fuel line.

The fuel line uses a quick connect fitting. Here is an example selling on eBay:

In case you don't already have it, here is a link to the X200 Workshop Manual:

Thanks for the manual. Disconnect tool just arrived. Might take a stab at it tonight. Do you know what page of the manual I should look for? Also do you guys know how many bolts hold the throttle body in. Thx

 

Ok so I'm about 20% in on this manifold and my body is already aching. The drivers side is easy assuming there's three bolts plus this one. So eight bolts total? Lmk where to start with the throttle body. Fingers crossed I can get it done without bringing in reinforcements

 

Guessing these torx need to be removed to get the throttle body off. No luck with the manual and was unable to download and install jtis.

 

I would spend some time and get the JTIS installed? What did not work?
Free JTIS

I hope you don't plan to remove those screws on the butterfly? Leave them alone.

No I meant this rusty torx screw lol. yeah for some reason I can't install jtis I will try again today and hopefully I can get this manifold off this weekend
