Okay, so you've got a Toyota Previa with a blown head gasket. ... The next few pix are taken after dropping the engine out from the bottom using a ... You can see a definite path between the water jacket and the cylinder. ... I believe this was a result of #1blowing and over pressurizing the cooling system.
Hi
There is are 3 bolts securing the starter motor, the starter motor is located under the passenger seat area and should be accessed from under the vehicle. The key is to get the van high enough to be able to slide comfortable under the side of the van to access all bolts, only the bottom bolt has a bolt and a nut the other 2 bolts have threads which secure the starter motor onto the engine there is one bolt at the bottom, one bolt in the middle and one bolt near the very top you will have to undo the 2 x 10mm bolts that hold the dip stick first to be able to get to the middle and top bolt of the stater motor. take your time and have some patience you will get it it just takes practice.
It could be that; the FAN MOTOR works but the fan-wheel is not turning. This usually happens when the center spindle of the fan-wheel RUSTS and eventually loses contact with the actual wheel itself.
Filling up with fuel may be a coincidence to your problem, or you may have purchased contaminated fuel.
The check engine light will log a "Fault Code" in the vehicles on board computer which may help you diagnose the problem.
A fuel leak, if present, is a serious concern and until you determine if the vehicle is leaking fuel you should not drive it.
Before you tear anything apart check your battery cables on both ends for looseness. Dirt or corrosion.will not let power through. I tried to boost my car and nothing would work. It was like the battery was dead so I got towed in. They put a battery tester on and the battery was fully charged so they replaced my battery cables and bingo everything was working again. One cable was not letting the power through it.
The toyota previa uses a formed silicone gasket for the valve cover and the cover is held in place by metric shoulder bolts ( 10mm). The valve gasket leaks because you can't get enough preload on the bolts to re-seat the old gasket when it gets old and shrinks. The shoulder bolts only allow you to tighten the gasket enough to seat the shoulder on the bolt. If you continue to torque down the suspected bolts, you will snap the bolt off ( don't ask me how I know this ). You can either 1.)replace the old gasket with a new one or 2.) remove the existing bolts around the leak area and put in new metric bolts that do not have a shoulder. You may want to put in a small sleeve into the existing bolt hole but shorter than the thickness of the valve cover to account for the smaller diameter bolt. You can now torque down the bolt and get enough preload to seal the valve cover without removing the old gasket. Make sure you use a torque wrench ( in-lbs) or be very careful not to snap these small valve cover bolts.
the impellors in the water pump are prone to corrosion,especially if no or incorrect radiator additives have been used .this will cause water to stay in motor & boil whilst the water in the radiator stays cold because it cannot circulate.try flushing radiator ,installing a new thermostat (which is more than likely not opening )& radiator cap,refil with correct additive,.if the car still over heats then you will need to replace the water pump.bugger!!
Has the vehicle been overheating or losing coolant? The symptoms you describe could point towards head gasket trouble (and other faults). Often, the exhaust fumes from a car with a failing head gasket will smell 'pungent' and 'sharp'.
Check the oil on your dipstick. If there's a greyish/cream sludge - sometimes referred to as 'mayonnaise' - this points towards coolant entering the oil system via a leaking head/head gasket.
Also check your coolant - is there any evidence of engine oil in it? Although the mayonnaise on the dipstick is usually the tell-tale sign of gasket problems.
If you suspect the head/head gasket try a special sealant such as:
Sounds like the Gas filter. Fairly easy fix. Locate gas tank. Follow gas line to engine, about half way usually by back door under the car, drivers side, is the small filter. Take a pic of it. Head over to car parts store. Show them what you need. It only takes a wrench and a bucket to catch a little gas.
