Heater Hoses Mess..cry for help from the Uk
Guys..68 gmc
heater is bypassed and the truck permanently runs with the old dash temp light glimmering..no thermostat inside right now which does not help, but the coolent are pumping round quickly enough. the top hose on the manifold has been put back into the rad[rather than the heater], but i am thinking this is causing issues, i intend to sort the heater matix rad out and re-connect[i need a heater!], but the waterpump doesnt seem to have a bottom left plug to connect the other heater hose back into it.. the truck hasa 72 bed on it, and i assume the engine is not 68 either, some advise would be much appreciated. |

Re: Heater Hoses Mess..cry for help from the Uk
Looks like the one that goes to the radiator was going to the heater core and the heater core back to the manifold. When the core failed they just ran the long hose back to the radiator.
If your core is no good then just plug both ends of the long hose going to your radiator.

Re: Heater Hoses Mess..cry for help from the Uk
You have to have a thermostat or a restrictor plate in the top thermostat housing "the coolant running around quickly enough " and the "old dash light glimmering " are NOT GOOD ! You will never get it to run cool without a radiator cowl in place You will burn up the engine ,Warp valves and blow head gaskets (If your lucky that's all that happens ) Find a mechanic replace the thermostat and hook the heater core back up your probably going to need a new heater core ,Replace the oil filter and change the oil ,Get a new fuel filter , get a new air cleaner and spend a weekend cleaning it all up before winter sets in ...What color smoke is coming out of the tail pipe already ?
![]() 1) new heater core ! 2) new fuel filter and air filter ! 3) oil filter and oil change ! 4) find a radiator cowl ! 5) Replace those old hoses ! 6) clean the engine compartment !!! Last edited by Grumpy old man; 09-15-2014 at 08:54 AM. |

Re: Heater Hoses Mess..cry for help from the Uk
good advise Grumpy, have the cowl [took it off to drain the radiator], thought the thermostat missing was bad news, the bay is certainly a mess so again it needs some love.
my issue with the heater core is, where does the bottom outlet connect to[i can see the top hose going to the rad right now from the inlet manifold is the the top part], i assumed it was on the base of the waterpump..but cant see where... |

Re: Heater Hoses Mess..cry for help from the Uk
Top of engine to bottom of heater core then top of heater core to top of radiator . Fix it before your engine burns up ! and please move that rubber fuel line away from the header or insure it for fire damage !

Re: Heater Hoses Mess..cry for help from the Uk
New fan and clutch fitted with a shroud , and thermo stat , heater core not arrived yet.. Tried it but if anything it's running hotter even quicker .
Tested the new thermostat and it works . Not convinced the new heater core is gonna help . Sure I am missing something here ..... |

Re: Heater Hoses Mess..cry for help from the Uk
Being your in the UK and driving on the wrong side of the road are you sure the water pump is running in the correct direction ?

Re: Heater Hoses Mess..cry for help from the Uk
Theres a good few specialists that keep all the normal service parts in stock in the UK, people like US Automotive, WASP etc. Failing that Rockauto will ship to the UK but beware of shipping costs mounting up as they will ship items from multiple warehhouses. There are even places in the UK that you can get OEM AC DElco stuff from, people like Bauer Millets in Manchester and a couple of others but be prepared to pay a premium. If you want specialist parts Wes at Classic Heartbeat has always been great to deal with over the years for me.

Re: Heater Hoses Mess..cry for help from the Uk
UKmark can you get parts over there? I mean can you walk into a parts store and buy parts for your truck or do you have to order everything? Just curious!

Re: Heater Hoses Mess..cry for help from the Uk
Don't know if you ever sorted out your heater bypass issues, but here's how I did it on my '67 Camaro. Works great, runs cool, etc. From intake manifold to fitting at top of water pump. Not a great photo, if you don't understand, let me know.

What symptoms/problems are you having? With a thermostat in place the engine will reach operating temp quicker than no thermostat. This is one purpose of the thermostat. Bruce |

This may help you also. This is out of the manual. You may need to flush the radiator also and back flush it really good.

Re: Heater Hoses Mess..cry for help from the Uk
That's a good point BLT, the truck only has the original warning light in the dash cluster , which is glowing red ... Quicker , much as this could be in-reliable of course, but it is spitting water out of its over flow .

Re: Heater Hoses Mess..cry for help from the Uk
I've seen them installed upside down before with your same symptoms ? Are you positive it hasn't already blown a head gasket ? you don't have to see oil in the water or water in the oil is it showing any white/grey smoke when running ? Again same symptoms . it's a very basic cooling system I'm begining to think you may have plugged/ clogged water passages from running straight water or some one installed the wrong set of heads ? this should be an afternoon repair job you shoudn't be still dealing with this problem after a month ! ... Somethings just not right in Denmark ...

Re: Heater Hoses Mess..cry for help from the Uk
Coolant spitting out of the overflow could be overheating or pressure from the combustion chamber (as Grumpy suggested head gasket). Time to measure the temperature of the coolant. If it is too hot you have a overheating scenario; if it is operating temperature and it is bubbling you are having compression leaking into the coolant system. Also you need to test your radiator cap. Will it hold the pressure it is supposed to? Good luck, Bruce
