My car really wants to be worked on...

[Billy Mild]

I have come up with a plan to pull the plenum. It appears my ZR-Juan wants some attention sooner than later. It appears the car has just started to leak a little bit of coolant.

I haven't even began to look where the coolant can be leaking from. Any tips to try and find the coolant leak? Would a pressure tester help at all?

Most likely leaking (seeping is a better term) from the injector housings. These bolts will back out over time.

Or water pump. Or any one of several coolant hoses. Just look around especially from under the front of engine area. I would not mess around with pressure testing (Just run engine to operating Temperatures/Coolant operating pressures).

I will try and get around to looking under the car this weekend. It isn't leading very much.

Do they still make water pumps for these cars? What about belt tensioners

Yep........you can get everything you ever wanted for the LT5 relatively very quickly (delivered) and even modified parts as you like....except maybe the Ignition Module

Jerry's New Water Pump

Haibeck Rebuilt Water Pump

Haibeck Reconditioned Belt Tensioner

Or.....see #8 LT5 Added Systems

Apply pressure

The expansion tank radiator cap is the standard domestic universal cap so any radiator pressure tester will work without the need for an adapter. It will easily show a leak without the need to warm up the engine to pressurize the cooling system.

Belt tensioners are hard to find. I had mine rebuilt recently by Marc Haibeck.

Got my rebuilt tensioner and water pump from Marc Haibeck too, great service and a really nice guy. The tensioner is super-easy to replace. The water pump is a certified bitch. In retrospect, I should have just pulled the radiator and a/c plumbing...would have been a much easier job

So I put the car on jackstands yesterday and there has not been any coolant leaked. I'm not sure if that was just some boilover or something. I can't find anywhere it would be leaking. Would it be a bad idea to pressurize the system for the whole weekend and see if it leaks?
