What hoses and lines hook up to radiator. What hooks up to part for toeing attached to radiator externally. 1992 Ply Van 3.3 L

where the heater core at.

Reference voyager van wiggle test. If that did not solve your problem, you may have a cam sensor going bad. There is no way for you to check the computer. With a scan tool hooked to vehicle, can you read codes?

When attaching vacuum lines, you need to remember only one thing. Mark each hose when you remove it from the original carb (quadrajet?) Hoses that attach to the baseplate are at full vacuum and should be returned to a similar location or to the manifold, using a "tree". Hoses that are connected to the body of the original carb only see vacuum when the throttle is opened. Those can be attached to the fitting on the right side of the front metering block. Most Holley carbs have no provision for the valve located at the front of early Q jets (bowl purge) nor do they have any electrical connections except for the choke mechanism.
The most important vaccuum line is the one for your power brakes. Make sure that one is firmly connected either to the rear of the carb baseplate or the manifold. All other lines are nowhere as critical as that one is..

Radiator Removal

1. Drain the cooling system by removing the radiator cap and attaching a 9.5mm (3/8-inch) inside diameter hose to the draincock nipple, located at the lower rear corner of the radiator tank. Then, open the draincock and allow the coolant to flow through the hose into a suitable container.

1. Remove the rubber overflow tube from the radiator and store it out of the way.

1. Remove the shroud's or finger guard's two upper attaching screws. Lift the shroud out of the lower retaining clips and drape it on the fan.

1. Loosen upper and lower hose clamps at the radiator and remove hoses from the radiator connectors.

1. For vehicles with automatic transmissions:
   1. Disconnect the two transmission cooling lines from the oil cooler fittings on the radiator. Intermediate flare fittings as shown remain as originally installed.
1. Disconnect the transmission cooler tube support bracket from the bottom flange of the radiator by removing the screw.

1. Remove the two radiator upper attaching screws.

1. Tilt the radiator back (rearward) approximately 25mm (one inch) and lift directly upward, clear of the radiator support and the cooling fan.

1. If either hose is to be replaced, loosen clamp at the engine end and slip the hose off the connections with a twisting motion.

1. Lift the shroud off the fan and remove from the vehicle.

1. Remove the radiator lower support rubber insulators.

if ur replacing it remove front grill disconnect both lines and carefully remove retaining clips from radiator if replacement is original eguipt mount & reconnect --if its a universal follow instructions usually cut off fittings and use clamps and hose to hook up

Follow the upper radiator hose to where it hooks on the engine. The thermostat is located inside the housing that the hose hooks onto. Hope this helped and best wishes.

Check your fluid level. If a trany is over filled then the fluid will begin to foam and blow out of the vent once heated. Or you may have a overheating tranny. You can disconnect the tranny lines from the radiator and blow air through the fluid line ports on the radiator to make sure your not getting a plug. You can also purchase an external oil cooler to hook inline with the fluid ports on the radiator just make sure that when you install it to install it on the port that returns the fluid back to the tranny not the one that delivers the fluid to the radiator, in other words after the radiator not before.

i cant give you a diagram but can tell you how to locate it easy just locate your radiator and follow the top big black radiator hose from the radiator to where it goes on the motor it hooks onto something metal there with 2 bolts unbolt that and there will be your thermostat...let me know any questions you might have..

Thanks,
Steve

Drain the system. Remove the upper radiator cover and the dual cooling fans (4 bolts and an electrical connector). Disconnect the transmission cooler lines and the upper and lower hoses.. The radiator should freely pull straight up and out. Reverse the process to install the new radiator.
