Hello Everyone I just fixed some timing issues only to have my D100 with a 225 slant 6 overheat about 1 mile from home I replaced the thermostat water pump and radiator cap ran it in my drive for 1 hour with radiator off Ran well no steam or overheating My question is I was looking for flow of coolant in radiator when thermostat opens I shot a video but its too big to send. Not sure if coolant is flowing, is it a high flow? Does anyone have a video of what it should look like? Thanks |

How is that possible when you have the radiator off? After a hour your motor should be a melted, warped mess. New parts won't do diddlysquat if your radiator is a plugged up mess! So what's the problem again, you lost me????????????????????????

Need the cap on for correct pressure and often to have correct circulation.. If you have a laser thermometer you can track the temps of the rad from top to bottom and check circulation. They are not expensive and are really useful. https://www.aa1car.com/library/tstemp.htm https://www.youtube.com/watch?v=KoT-PWg8Ahs |

Hello Everyone Well after working on the floor boards I took my truck (1971 Dodge D100 with 225 slant) out for a ride The filler neck on the radiator cracked and the truck overheated.... After driving and waiting 20 minutes between stops I finally got her home (4 miles) Well I found a 1974 Valiant radiator used near me and bought it. Installed the used one are ran it around the block.... A little steam came out through the filler neck port and was deposited on the driveway Went for a longer ride and lots of smoke came out same place now engine is running poorly and I fear I have damaged it. Top hose going into radiator was hot bottom hose from water-pump was cold New water pump thermostat and hoses I'm stumped any help please? I fear I now have a bad radiator as well as head gasket? Runs poorly and knock after I shut off key. thanks |

No flow through your "new" radiator. Lower radiator hose should at least get warm if it is allowing coolant to flow. Regarding engine noises-knocks and what not. If starting the engine when it is cold after sitting overnight, does it still make noises? |

Hello Good news She started up without any issues I ran her in the drive for an hour with a funnel full of coolant and saw many tiny bubbles escaping. When the lower hose was as warm as the upper I shut her down Took her for a 17 mile run and she did well no hissing sputtering or detonation Thank you everyone |
