replace the connector
That is called a quick disconnect fitting and it requires a SPECIAL tool to get it loose.
It take a special tool to release the hose connector. I went to O'Rielly and they show me the Dorman Quick Disconnect replacement part ($6.29) and the Disconnect tool set ($19.99). It took the 3/4" disconnect tool to release the broken hose connector on my GMC truck. Snap on the 3/4" disconnect tool onto the heater core tube, then slide the tool into hose connector to release the dog ears inside the connector. Then pull the connector off. It took me about 30 second to remove the disconnect once I had the connect tools.
Remove the tank if necessary. Detatch electrical connector & hose. Remove motor from tank. Install in reverse
Remove the reservoir bolts and nut. Disconnect the motor electrical connector. Detatch the fluid hose from the reservoir Take the reservoir out.
Unhook hose and connect to new connector very simple.
The connector into the intake manifold of a GM 305 and 350 has been known to be quite fragile. If the connector has broken you have little choice but to replace the manifold.
you may have to remove the intake from the block and then use an extractor tool to remove the rest. then replace the connector.
Someone would go to the hardware store to purchase a stripper connector replacement for a garden hose to fix it first. Then he or she would use pliers to connect the stripped connector to a garden hose and then it is fixed.
In the engine bay, remove the inlet and outlet hose from the firewall for the heater core, get a heater hose connector that matches the hose sizes (fair warning they are 2 different sizes but i cant remember) and just join the 2 hoses together with the connector and some clamps. you wont have heat or defrost by doing this though.
All depends on the vehicle application. Usually you can disconnect the harness connector and remove from hose attachments or pushed into the charcoal canister assy.
Cut the dipstick tube with a tubing cutter below broken dipstick and remove Use rubber tubing and hose clamps to reattach tube pieces
