Rear Bumper Guard & Side Foot Step

Rear Bumper Guard

Let me clear this right away, before we get into the details, I do not like rear bumper guard or bumper bar or bike protector or whatever! In my opinion it spoils the look of the vehicle disrupting the clean lines. For almost an year i chose not to have the rear guard but finally I had to give in. No let me rephrase it, I was made to give in thanks to a stupid errant careless motorcyclist who was not looking where he was going and rear ended my Crysta which was parked at the side of the road and inflicted some serious damage to the bumper and panel. Idiot.

So here it is, the Toyota genuine accessory bike protector. Made of plastic and metal, but mostly plastic except the fittings. It is not as strong as I would have liked but then I don't want extremely rigid metal bar which would transfer all the force to the chassis, this would deform and absorb some of the forces of impact. Should be okay for light nudges heavy impact would break it but anyway still better than having a naked rear end.

Installation instructions

Side Foot Step

Decided to get a set of side foot steps installed in the Crysta for two reasons. They are:-
  1. Its easier for the elderly to clamber up if there is a side step.
  2. The side step offers a little bit of protection from low speed impacts by overzealous two wheeler riders. A scooter rider once manged to dent the running board of the Crysta due to his hurry.
Once the decision was taken to go ahead with the purchase of side step I was confused as to which one to go for. Generally people opt for the Aluminium or Steel variants which comes ether as a flat step or as a round bar with rubber grips for steps. I do not like either of these models as they look non original equipment (OE) accessory and a couple of reasons which i will list below.
  1. It leaves a void between the body and the step which is no for me aesthetically.
  2. Or if it is of the type that sits close to the body then it juts out farther than i like.
  3. If it is of the type that does not leave a gap and does not jut out then the actual "step" area is limited. Which does not help those who nee to use it.
This is why I delayed the side step installation till now. There was none in the market which looked good!

My wait finally came to an end couple of weeks ago when i spotted a Crysta at the dealer's with a OE looking side foot step. Soon an order was placed for the same and it was installed a week later.

The side foot step sits perfectly aligned with the body of the vehicle and there is no gap between the rear of the foot step and the body, meaning you cannot see the chassis of the vehicle between the foot step and the vehicle body. Great! Also both ends are closed and meets the body of the vehicle. The material is steel frame with ABS plastic surface and it looks and feels premium just like an OE foot step.

I will let the photos explain the rest.


Installation instructions which came with the foot step

Any negatives or disadvantages due to this install? I can think of two.
  1. They reduce the ground clearance by a fair margin so you have to be careful while going over large ruts.
  2. Since they protrude out a bit it could affect high speed aerodynamics. When I say high speed i mean really high speeds. Should not matter at 100 - 120KPH.

1GDFTV Water Cooled Toyota Turbo Charger

Toyota has chosen to implement water cooling in their GD series engine turbo charger, usually Diesel engine turbos are not water cooled and gets only the oil line to keep its CHRA happy. Water cooling the turbo is a very welcome move which will help increase the durability by minimising the chances of oil coking in the CHRA when the engine is shut down and the turbo is still hot.

I believe is a first in this segment, a water cooled turbo charger for a Diesel utility vehicle. But this motor is not limited to utility vehicles though, this 1GDFTV engine powers the Land Cruiser Prado also.

See the picture the turbo charger from under the vehicle. There are two drain tubes coming out from the turbo, one for oil and the other one for coolant.

Water cooled turbo chargers are not a new concept and are mostly found in turbo charged Petrol engines. Turbo Petrol engines run hotter and has a higher exhaust gas temperature (EGT), compared to the Diesel counterparts, so they get water cooling as standard in almost all installations. Diesel engine turbos usually gets only the oil feed line for lubrication and water cooling is not usually done as the operating temperatures are lower.
