Lao Yang’s product: Harvard H5 air conditioning air inlet rodent protection net
In winter, the weather temperature drops suddenly, when you get out of the car and come back to park, you should pay attention to prevent small animals from getting into the engine cabin, especially rats. Brothers who have read Lao Yang’s post all know that Lao Yang used to post that the intake of Ha-5 engine was equipped with a rat-proof net. Last time, a mouse went into the air filter box to make a nest and almost scrapped Lao Yang’s engine. Lao Yang installed an air-intake rat-proof net. This time the abominable mouse actually climbed into the air-conditioning air inlet to make a nest. One night, the thermal insulation cotton of the engine cabin firewall was crushed and dragged into the air intake, and Lao Yang was targeted by the rats.

This is the anti-rat net for engine air intake installed by Lao Yang before. Interested children’s shoes can take a look at the previous post.

This is the anti-rodent net for engine air intake installed by Lao Yang before.

This weekend, it happens to be the Beginning of Winter, who has time to install the rat net.

Under the wiper motor, a large piece of thermal insulation cotton from the engine firewall was gnawed off by rats and dragged into the air inlet of the air conditioner.

Last time, I did not do the anti-rat net of the air-conditioning intake, because the air-conditioning inlet of Ha-5 was really difficult to reach, and it was blocked by the steel plate above the air intake at the innermost part of the air intake. The hand can only reach in a little bit. But this time Lao Yang must install this anti-rat net.

The air inlet of the air conditioner is behind the wiper motor, which is blocked by steel plate, which is invisible and difficult to touch.

First remove the engine cover, wiper arm and front trim cover.

Remove wiper arm

Remove the decorative cover of the wiper arm fixing bolt with a plastic crowbar, unscrew the fixing screw, lift the wiper arm upward as shown in the picture, and gently shake it to remove the wiper arm.

Remove the plastic bolts and screws on the decorative cover and remove the decorative cover.

Remove the decorative cover

Nima, this air duct is really dirty.The air intake duct is under the red box, which can not be seen and difficult to touch.

Remove the engine cover and remember to disconnect the wiper spray pipe first. After removing the engine cover, you can barely see the air inlet from the left.

Remove the engine cover

Roughly measure the position of the air inlet with a tape measure and prepare to cut the steel plate above the air inlet. The main purpose of the opening is to accurately measure the size of the air inlet.

A cut is made in the position of the red box to facilitate the measurement of the size of the air inlet. The engine cover bracket has rust unexpectedly. I will remove the rust and spray paint later.
The two rods in the air duct are wiper connecting rods, and there is a connecting shaft in the middle. You can take advantage of this opportunity to maintain and lubricate the connecting shaft.

It hurts to open a hole with an electric drill first. Before opening, find a cardboard to cut, extend through the middle of the opening to cover the air inlet to prevent debris from falling into the tuyere when drilling.

Some of the debris cleaned out of the air intake, evil rats.

When the hole was cut and enlarged with an angle grinder, Xiao Wu suffered. It hurts to open a hole with an electric drill first. Before opening, find a cardboard to cut, extend through the middle of the opening to cover the air inlet to prevent debris from falling into the tuyere when drilling.

The steel net outside the air filter element of the excavator is used as a rodent net.

Cut off a piece according to the measured size

Using the opening and the hole in the middle, Lao Yang finally accurately measured the size of the air inlet of the air conditioner, 165 mm long and 87 mm wide. Use the steel net outside the filter element of the digging machine to make a rat-proof net.

First draw a sample with cardboard, 165mm 87mm in the middle and 30mm flanging around.

Fold the steel mesh according to the size, flanging the four corners and use the edges and corners of the wire mesh to catch each other. The lower opening of the steel net is slightly larger.

The size of the lower opening of the wire mesh is slightly larger.

The flanging of the steel mesh is glued inside and outside with double-sided glue, so it is more firmly glued.

Pass the finished steel mesh through the opening at the arrow below and try it at the air inlet to see if the mesh is the right size.
If appropriate, tear off the inside double-sided tape and reinstall it.
It is recommended to find children’s shoes with thinner arms to do. Lao Yang’s hand is full of scars.

Pass the net in from the red arrow position, first try to install it, fit, tear open the inside of the net tape, install it.

First try to install, fit, tear open the inside of the net double-sided tape, install it.

If the cut hole is sealed with a thin aluminum plate, it must be sealant. As Lao Yang has fixed the size of the air inlet for children’s shoes, children’s shoes no longer have to cut a hole like Lao Yang, make a net directly according to the size, and just pass the net in from the original opening and install it.

Seal the opening with thin aluminum plate and sealant.

Finally, reinstall the decorative cover, wiper arm and engine cover. Call it a day.

Install the decorative cover.

Install the wiper arm back.

Install the engine cover, connect the wiper spray pipe, and complete the installation of the rodent net.

Carry on the engine cabin thermal insulation cotton repair, buy online from adhesive fireproof thermal insulation cotton to repair parts bitten by rats.

This self-adhesive fireproof thermal insulation cotton is much better than the original factory thermal insulation cotton, this fireproof thermal insulation cotton is not lit, but also reduces vibration, the point of the original car, is fixed with screws, no anti-vibration effect. Too bad I can’t replace them all.

Repaired thermal insulation cotton

Clean the air conditioning duct in the car and replace the air conditioning filter element.

Clean and disinfect the air duct inside the air conditioner.

Remove the glove box, remove the filter cover, you can see the air conditioner filter element (white object), above the air conditioner filter element is the air door, below is the fan, now is the air door open state, that is, the external circulation state.

Now the throttle is closed upward and in the state of internal circulation.

The air conditioner filter element that has just been changed has been gnawed away a little bit, and the debris and mouse shit have been cleaned up, but there are still traces of rat urine. Replace the new air conditioner filter element.

Replace the filter element

Note that some filter elements are marked with arrows, note that the arrow is downward, the arrow indicates the direction of air intake, and if there is no arrow, keep the letters above installed in a positive direction.

Finally, spray the rodent protection agent in the engine cabin, and the rat protection agent purchased online is sprayed in the engine cabin, and the position of the conduit should be sprayed to prevent the mouse from gnawing the conduit. Pay attention to do a good job of protection, this anti-rodent agent has an irritating smell, basically tasteless after drying, but the anti-rodent effect remains to be seen.

Since Lao Yang has already fixed the size of the air inlet for the children’s shoes, the children’s shoes no longer have to remove the engine cover and cut a hole like Lao Yang did. Everyone directly makes a net according to Lao Yang’s size, and just advances the net from the original opening to install it. Remember to find a girl’s shoe with small hands and thin arms to help. It will be easier. After parking in winter, the engine compartment is warm and small animals often enter the cabin. Therefore, the engine compartment should be checked frequently to prevent small animals such as mice from entering. Especially for mice, we should prevent mice from making nests and gnawing on wire pipes.
Let’s call it a day.
