Default Power Steering and Over heating Problems In my Sierra

Hello,

I have recently purchased a 99 turbo even have posted a review but have some problems with engine overheating and hard power steering

1. I have changed the coolant recently
2. power steering fluid changed and even the leaks were rectified

Can anyone suggest methods for bringing down engine heat and power steering motor rehauling

1.Check radiator condition and overhaul if necessary.
2.Discuss with your Electrician if you need to install an electric fan
3.Check Power steering pump
4.Check Steering box.

does your coolant stay same level for 7 days at least. this info will help to zero on other causes.
is the power steering bleeding done properly (probably air in it).

Default Sierra Problems

1. Flush Out the Radiator (and overhaul the Radiator if necessary).
2. Check Water Pump. Sometimes Waterpump may not be working as expected.
3. If overheating while switching on the AC, may be AC-compressor is giving load. Check the Compressor with expert AC-mechanic.
4. You can also upgrade the Condensor fan to High speed fan (fan of Opel Astra)
5. I am not sure abt Power steering. Normally I overhaul the Power Steering once in two years.

I agree, but have the electric fan switch manually controllable..Also, itsd mostly the pump which is the culprit for PS failures, Change with another one and carry on..

Default Power-steering

@Headers....
oops...typo ....Its not every two years.... actually its every year... Since mine is a 1994 Sierra, I try to keep the vehicle in Good Condition, by servicing/repairing/replacing (whichever is required) the PowerSteeing, Suspension, Radaitor Flush Out, Engine Mount Ruubers, Brake Cylinders & Vaccum, etc etc.
Normally I do lot of travelling between Bangalore-Mangalore either in my Sierra or Fiat Petra, and hence I make sure that I keep all these things.

Normally in my Sierra, for last three year, I can see the Power Steering oil Leak around the PowerSteering Unit in 11 months or so..... and hence I get it overhauled/service.

For me , the logic behind the Servicing depends on the Road Conditions where I drive.

do check the high pressure hose fitting thats where the leak occurs.

my high pressure hose (nissan) was having a minor leak, oil dripping on AC compressor - getting the hose off and + new fittings meant time and labour cost so I did a diy / juggad. bought a high pressure 3/4" Clamp and fixed it over the existing hose fitting. No leak now!!
