SOURCE: 98 chevy s-10 wont start

real comon starting problem for these is moisture in the cap and rotor and plug wires. replace cap, rotor, and wires. while you have the cap and rotor off check the two vent holles in the base of the distributer to see if the screens are plugged. be careful with the srews that hold the cap on the distibuters are plastic and will break.

I would check the inside of your oil cap. if it has a white or milky residue texture you have a blown head gasket or head. have that checked. good luck

2005 Pontiac Grand Prix running hot - no leaks found in coolant system may be air locked or what?


Did you do a pressure test and do a leakdown test on coolant system? There's a bleeder connector on the drivers side if the intake that you can open once warmed up. Air bubbles will come out till antifreeze flows smoothly'

Look on the back of the engine for antifreeze-either by number 1-2 cylinder or back by the brake booster. It is a know problem with Saturn engines, leaking by the rear intake. Check under the surge tank, they crack and leak too-check the bottom of the water pump for leaks, it has a weep hole that, if the seal inside is broken, will leak. you need to look for symptoms and evidence of leaks-if there is no obvious leaks from hoses, or outside the engine anywhere, it may be a head gasket-check your oil for a milky texture, or greyish color. check the bottom of the surge tank for oily residue, and look for smoke coming from the tailpipe.

Lossing antifreeze but no puddles we think its the antifreeze intake gasget?


if no puddles or no keaks you can see, then its probably your head gaskets, or the intake gaskets leaking. look all around intake to see if you see any leaks. if you do its your intake gaskets. how does the coolant look! on my car when the intake gasket was leaking, it made the coolant look milky and a chocolate type mixture. so check it out first, the intake gasket. Coolant may flow through the gasket to the inside of the engine and mix with the oil. Pull the oil dipstick out and look at it. Oil mixed with coolant will have a thick consistency. Examine the oil filter cap for any rusty-looking residue. good-luck.

Leaking antifreeze from back of engine


I would take the car to another mechanic. With a few tools (pressure tester, mirror or scope, and a good light) that mechanic should be able to narrow the search down to the source. If the heads, intake, and hoses to the heater core are dry. Then it could be coming from a freeze plug behind the trani or maybe from the drain-plug where the heater-core is.
Good-luck.

Oil pressure problem on a 2001 tj wragler 4.0 sport


If you are using antifreeze, regardless of the mechanics test results, it cant just "disappear" it must be going somewhere!!! My guess is that it's getting into the engine and causing the oil pressure problem. Likely you either have a small head gasket leak or a small crack in the cylinder head that only opens when hot. Instead of a pressure test have a hydrocarbon test done on the radiator as well as a cylinder leakdown test. One of those tests as well as oil pressure test with a mechanical pressure gauge, should tell you more about what is going on.

2001 chrysler seabring put anti freeze in reserve box and 2 days


Cracked head or head gasket will cause antifreeze to get in the combustion chamber and be ignited with the gasonline.
The white smoke when you first start lets you know of this condition. Each cylinder will need a compression check to test for leaks.
Pressure checking the cooling system does not provide you with enough information.
Its possible that your coolant is slowly being burned off in the cylinders possibly caused by a blown head gasket or cracked head,also i would definately check your oil and see if its overfull or milky looking,usually indicates a head gasket problem also.If your intake gaskets are leaking internally your engine could be sucking it in and burning it. With no leaks coming from the vehicle these are about the only things it could be!!
