Question about 1984 Chevrolet Blazer

1 Answer

85 Blazer s10 4x4 looks to be dripping trans fluid near the rear of engine. Small to medium size fluid leak when sitting. Seems to drip from unknown location, down onto the exhaust line. When idle, exhaust line smokes from fluid residue burn off and also from somewhere close by, above exhaust line, maybe engine burn off. Doesn't seem to be pan or any issue up front or rear of vehicle. Any ideas or suggestions on next steps is greatly appreciated, thanks.

    Wiped clean the trans pan, cooling lines, crimp clamps on the lines and any area that was overly saturated with oil / trans fluids.

    Started vehicle and saw a drip on the exhaust line where it comes across the front middle underneath behind the engine.

    Turned off and crawl under, could not see where anything was visibly dripping or seeping thru. The drip would seem to come from the trans pan if i go with where it looks to line up at.

    There was some fluid on the bolts for the trans pan before the wipe down but there really wasn't anything that i could see after starting it up that would point to the pan or seal as the issue.

    I did attempt to see if the bolts needed to be tightened and was able to turn a few using a hand socket set about a 1/4 to 1/2 turn varying between about 5 of them.

    I hesitate to torque too hard on the bolts to tighten them up as i'm not sure if this will cause more damage to the seal or if they are not supposed to be cinched down really tight.

    I'm guessing here but i am considering that perhaps the seal, if it's bad causes these bolts to be tightened down as it deteriorates further. I don't know now...any help is appreciated, thanks for any you might have.

My 85 honda accord is blowing white smoke out of the exhaust pipe in the rear and it appears to have something dripping onto the heat shield under the car, what do you think could be the problem?


check the brake system for any leaks. check the master cylinder for leaking out the rear of it. if you take the master cylinder nuts of that hold it to the power brake booster and slide the master off the booster and look at the rear of the master to check for a fluid leak or dampness. if you see this replace the master cylinder. also sometimes the power booster will suck the fluid were its drawn into the engine and burnt and the smoke will look white. another thing that causes white smoke is a bad head gasket as the coolant is sucked into the combustion chamber and burnt, it can also leak externally and cause the dripping you see.

I have a steady drip of coolant leaking out of my 96 Cadillac Seville I noticed it is dripping underneath from about center and rear of where the engine sits close to the oil pan it actually leaks down...


You are going to have to use a pressure tester on the cooling system and follow the drip back to it's source.You may have to remove items to get a clear view of the leak source.Small mirrors can be helpful too,as is florescent dye added to the cooling system to help identify the leak.

I have a red leak that appears to be dripping from the 2 lines that run near the housing of my 94 blazer. I noticed two separate drip trails parallel from each other, about a foot or so, when I backed up...


Yes it sounds like the tranny. Possible an easy fix though. There are two line that go from the tranny to the radiator or possibly a trans cooler. The connections may be lose. There is a cheap way to fix this and that is buying the brass barbed hose fittings that will screw into were the existing line go into the tranny and get transmission cooler hose and run new lines. Or replace it with original parts. I would like to say you are probably be fine to drive it as is just make sure to keep fluid level full. But if they come completely out or break lose you will be stuck and will lose all 7 to ten quarts of tranny fluid. Also when you check you tranny fluid it has to at operating temp and the engine running. Good luck hope this helps.

I have a leak somewhere in the tranny line on my 88 mercury cougar. how do I check for certain? every morning there is a puddle of tranny fluid underneath the car. It still has fluid in it and shifts but...


To make this as simple as possible, the trans lines go from trans to radiator back to trans. The question is where is puddle? If near radiator, then radiator must be going bad or you have a crack in radiator where trans fluid circulates. If in front of trans then front seal in trans is bad, if in middle then pan gasket bad, if in rear the rear seal bad. Hope this helps.

Trans-axle fluid leak


checking the transmission fluid involves lifting the vehicle and removing a plug on the transmission, it is quite difficult and messy if you don't have access to a lift, the vehicle has to be level and at operating temperature in park, there is a small plug on the side of the transmission near the passenger axle shaft. remove the plug slowly, i believe it is an 11mm bolt, if fluid drips out, the level is ok, if no fluid comes out, there is a small plastic screw on cap on top of the transmission itself on the driverside near the oil filter cap, add fluid slowly untill fluid starts to drip out of the plug hole, once the fluid starts to drip, insert the plug and tighten, don't overtighten, just snug it up.!!!make sure you use the right fluid, this is important!!! i believe your fluid is dextron 6, double check in your owners manual, the use of any other fluid will cause damage!!! also, do not remove the small plug on the front of the transmission, that is the pressure plug, all the fluid will shoot out with force if that plug is removed!!!

Leaking clutch 85 s10 blazer when I bleed the slave cylinder oil leaks out the bell housing


First, unless you have just done some clutch work you should not need to be bleeding the clutch hydraulic system...that shows that it's leaking. There is nothing inside the bellhousing that has anything to do with clutch fluid, so, the fluid you see is either engine or transmission oil (rear main seal or seal on trans input shaft) Could it be that the clutch slave is leaking and it's running down and dripping at the bottom of the housing? (clean it up and check that)

1998 SUNFIRE GT TRANSMISSION PROBLEM


There are 3 transmissions that could be in your car,the 3 speed auto and 4 speed auto overdrive,and of course the manual 5 speed.The 3 speed is designated the 3T40,the 4 speed auto is the 4T40E trans.To check the fluid level,first,the car has to be warmed up to at least 100 degrees Fahrenheit.The car has to be raised in the air,as there is a steel plug in the trans case that has to be removed to check the fluid level.The plug takes an 11 mm or 7/16" socket or wrench and is located on the passenger side of the trans case,near where the passenger side axle engages into the trans.The procedure is to warm the car up to at least 100 degrees,engage the shifter into each gear selection pausing for about 5 seconds in each gear,then remove the plug.If fluid drips out,it is full.If no fluid drips out,add fluid through the top of the trans after removing the red plastic cap,and make sure to use a long funnel to avoid a mess.Add fluid until it drips out the hole.When done,replace the plug and cap.Just a note,a transmission does not "use" fluid like an engine uses oil.If you have to add fluid,that means there is a leak that needs to be repaired.Good luck
