    Cylinder head gasket replacement job

    The temp gauge was not reading at all. I bught a new sender last year swapped it out; unbeknwnst to me the sender was bad right out of the box; my multi-meter confirmed this. I tested a NEW one at the parts store before I brought it home; the replacement works as designed. My temp gauge after...

    I checked the box for the sender I got & it was a Standard TS71 and it has a male blade connector on it; could this be an improved connector instead of the senders from the 1960's & 70's????

    Cylinder head gasket replacement job

    In looking at the PDF that was the style of temp sender unit that was in the motor originally; I was not aware of the vintage of the engine until a couple months ago. Also the original temp gauge was not functioning when I swapped it out for a unit from LMC truck; (I specified an 84 Suburban for...

    My truck may be a 1984 model but the 350 in it is from the 1970's. So maybe I need to change the sender again; only ask for one for a 1970's Suburban this time.

    It's what the parts guy gave me & it spun into the side of the block just like the other with no issue.

    Cylinder head gasket replacement job

    I changed the radiator to see if that would cause the temp gauge to drop as well as the transmission cooler. The radiator appeared to have some crap on it that was built up & dried crusty; the cooler for the trans had mummified oil on it from the A/C condenser. I still need to get that stuff...

    The truck is not overheating (nothing visual) except the overflow jug is almost full if that means anything.

    Cylinder head gasket replacement job

    The original temp sender had a round flat disc on the end of it with a crimp terminal that slid over it. I did not like that setup from the get go; I purchased a new sender that had an actual mae blade on it the sending wire I know would have a solid connection on it. I also changed the...

    Cylinder head gasket replacement job

    The engine in my 84 is either a 1973 or 1974 era 350 there is no coolant leaking from the water pump nor the head gaskets at this time. I am thinking it may have an electrical issue with the temp gauge as I installed a new sensor. The trailer harness was mucked with before I bought the truck by...

    Cylinder head gasket replacement job

    I am thinking on putting a ground between the temp gauge and the firewall to see if that makes the gauge settle down. I did install a new temp sender a couple months ago; the same time I swapped the temp gauge

    Cylinder head gasket replacement job

    I just added another quart f 10w30 to the truck the other day & no "chocolate milk" oil. It is due for a change here in about a week. I have noticed the radiator a little bit on the low side after a few days of driving. Is it possible the coolant could be getting burned right away & not reaching...

    Thanks; I will have to do that. Lucky for me I only work 10 minutes from home; city street driving, no highway.

    Cylinder head gasket replacement job

    I will be changing the thermostat first to see if the temp gauge drops, as it's pegged at 260 after about 10-15 minutes driving. This would be my first rodeo changing the head gaskets. I have no garage as I will be doing this in my driveway & my truck is my DD currently as I have no backup...

    Thermostat not working, no coolant leaking from water pump, no pressure on upper & lower hoses

    I put a brand new thermostat in my 84 K20 Chevy Suburban 350 last year & toook note the gauge was not working so I changed the thermostat and the sender on the block; still no indication of temperature. At this time I installed a new temp gauge in the dash cluster; and things started working...

    1984 C20 Fuse Panel and Harness examination

    Would the slot on "row 8" marked for LPS be for the headlights? From the way I see the "INST LPS"; this looks like the fuse for the instrument cluster lamps? My headlights are currently not operating at this time. I just replaced the pigtails and put in new headlights a couple weeks ago. The...

    Forgot if I put an intro here

    The burb is a transplant from Texas; originally purchased by a Texas rancher "used for going to town"; the clock has over 260,000 on it. I am currently in the middle of having a fuel problem. A friend came over and with a bit of help from him he figured out the truck's "fuel circuit" in the...

    Forgot if I put an intro here

    The only rot is thee lower outer rocker panel under the driver side back door. The inner rocker is still solid. This was originally a Texas rancher's truck bought new in 1984. The second owner who drove it up to MN. had a copy of the build sheet which has the dealer's name on it. Almost forgot...

    Forgot if I put an intro here

    Hello from the frozen north; aka, MN. where winter sticks around until the end of April/beginning of May. I picked up a 1984 K20 Chevy Suburban last year. Straight away I installed new front U joints in the stub axles for the 4x4 and did a full replacement of the front brake system; rotors...

    Ethanol Free Or Premium Or Either

    Ethanol gas in small engines; i.e. snowblower, lawnmower, etc will varnish if not run dry out of the carb; also ethanol does destroy seals in carbs over time if the blend with gas is too much in the ratio of gas-ethanol. The same applies to cars & trucks as well. For several years up here in MN...

    Horn does not work

    Not yet. I need to do one. The current column in the truck is from a 90 Suburban, as the original column had all thee main 4 bolts "very, very, very loose"; dangerous to drive. I located a burb a guy was parting out over in Sconny and went there to pull the column out of that burb & it was the...
