I have a coolant leak under my van towards the rear,is there any way I could bypass the rear heater and would it stop the coolant from leaking there? Thank you.

You could plug or bypass the heater lines that go to the rear heater.

How would one go about doing this? I'm having the same problem on my '99 Limited and am worried about blowing my head gasket. This van has been dead reliable, otherwise. I plan to get the rear heater hose later I just can't afford it right now.

Just get a 5/8 - 3/4 nipple and take the lines off the heater and tie them together so water will still flow.

I've jumped out the rear heaters on both of my 99 t&c limited. It is a bit of a pain in the butt and takes some time but doable. Unfortunately you need to remove the plenum (the intake manifold that sits on top of the motor) to get to the firewall where the heater connections are located. You also end up taking off your alternator bracket, coil pack, throttle controller and EGR valve and housing. Replace the EGR valve as you see fit. You also have access to the serpentine belt tensioner bolt so replace the tensioner as needed or if it hasn't been replaced in awhile. I suggest you replace the plugs while you are in there as that is about the only way to get to the rear ones. Be prepared for some of your vacuum hoses to snap when you try to remove them as they are old and brittle, especially the one on the bottom of the plenum. Purchase a plenum gasket kit (short $), plugs, heater hose and clamps, antifreeze, vacuume hose, EGR valve and belt tensioner as needed. Good luck.
