Location of freeze plugs on 92 toyota 4-runner sr5 3.o


They will be on the lower block under the manifolds a few inches, they will be about 1.25 inches in Diameter and recessed into the block, If you have a block heater in your truck just follow the cord back, when they install a block heater they remove a frost plug and install the heater in the hole in the block.

How to install block heater on 97 chevy tahoe


The frost plugs that block heaters go in are along the sides of the engine block. About midway up from the bottom of block where the oil pan mates to the top block deck. 3 or 4 on each side, 1 to 2 inch diameter round metal plugs just slightly recessed in the block. Look below the exhaust manifold, behind the exhaust pipe on the block. Frost plugs are easy to punch out as long as you can get to them.
Punch in one side, and the other side will start to come out-then grab with pliers or vice grips to remove the plug.

When you buy a block heater for your Tahoe, it will come with an instruction sheet, and a diagram of the preferred or recommended frost plug hole to use the heater in. It will also usually show the positioning of the heater element in the block-how to orient the heater into the opening so the element does not touch the block anywhere, but is placed in so the element is exposed in the water jacket of the engine. That make sense? You do not need a sealer, as the block heater has its own O-ring rubber seal. When inserted and tightened down (small wrench or socket, about 3/8 inch or smaller size, do not over tighten-follow sheet instructions), the o-ring should not leak. Be sure and clean that recess well that frost plug was in- get all the rust and scale off with rags or emery cloth (sandpaper).
Not hard at all to install a block heater once the frost plug is removed. Getting access to the frost plug is the devil to deal with. If you are unsure, have it installed for you.

Location of both temperature sensors


put the truck up on ramps today, and look at it from underneath,there is a one wire sender, At the back of the block that is the oil sending unit. It is about 1.5" in diameter and has a gold stud coming out of it. Then down 2 inches, and towards the front 2-3 inches, under the intake manifold, but still on the block, is another unit. It is about 3/4" diameter, and also has a gold stud coming out of it. There is one wire and it is red with white stripes. that is one of the coolant sensors, in the coolant lines coming out of the firewall for the heater, there is a sensor spliced in. It is located right above the alternator, Look for a 2-wire sensor with LG/R and GY/R color wires.

There are several types of heaters. The easiest one is the type that that takes place of your oil dipstick. Just remove dipstick put dipstick heater in and plug er in ! Easy ! The others involve removing freeze plugs or cutting coolant hoses YUK :(

Heater Blows cold air


You could have a blocked heater core. Check for two heater hoses running into the firewall in the back of your engine. They should be together and about 5/8" in diameter. If one is hot and the other is cooler then your heater core is blocked. Unhook both hoses and use a garden hose to back flush. Be sure to catch the coolant and dispose of it properly.

Location of block heater cable on 05 F350 diesel


The block heater is already installed in your 6.0. The cord may not be there as it is an option in some states and standard equipment in others. The best way to see if your cord is there is to crawl under and look up by the # 4 cyl and you will either see 2 prongs sticking out for the cord or you will see the cord. The cord should end in the front bumper behind where the front tag would be. If you dont have the cord Id suggest getting it off ebay as it should be cheaper than the dealer. Hope this helps.

How do i install block heater in 91 2wd 4 cyl sonoma


Hi ryan, yes my friend the best bet is to drain the coolant,as for the block heater,not sure which side for the sonoma but basically it is a frost plug with and internal element attached to it,once you unplug the cord typically there will be a small screw to remove, use a small punch or whatever will work and pop one side to roll the block heater so you can remove it,simple my fried,by the way a new block heater will come with installation instructions :) have fun and good luck ryan take care.
