Question about 2001 Cadillac Catera

2 Answers

I have a 2001 Cadillac Catera that the oil light and alarm has been coming on when I come to a stop or slow down after driving the car for about an hour. Had the oil change and that solved it for a few weeks but now doing it again. Alos noticed that the Temperature Gauage was a good indication of when the oil light would come on. If the Temp went above the middle, the light was sure to come on. Never overheated just would go slightly above the middle range. Also, the cooling fan comes on a fair amount. Last but not least, now I appear to have a coolant (antifreeze) leak and they want to charge me $800 just to replace hoses. Help!

It may just be a bad sensor. The pressure could be tested with a mechanical gauge, but the sensor is probably so cheap it's not worth paying a shop to do a diagnostic if you can replace the sensor yourself. If it's not a bad sensor the oil pump may be worn out, or maybe the engine bearings are worn. A thicker oil might buy you some time on it.

Check your fuses, also I'm nt sure if there is no spark at all or just not at the engine so I will suggest scecking to see if there is spark at the coil, if not check to see if the cil is getting power. if there is spark at the coil then check the lead wire. If no spark at coil but power to coil then it's time for a coil. Good luck and remember to rate all solutions you get, thanx.

SOURCE: 2001 cadillac catera: oil in coolant?

The Problem, My friend, is a leaking oil cooler. this item is mounted, inside the engine, under the intake manifold. The cooler or the connections are bad. Coolant flows through the cooler, if it brakes then the oil will contaminate your coolant and make a mess.!! Have it checked. Must times is the seals at the pipe to cooler flange connector. will need new seals.. Hope this helps.

SOURCE: 1999 cadillac deville overheating

my husband did everything that everyone else did that had this overheating problem. It was so weird that my engine cooled at a light and heated up going down the road. I have a north star 4.6 engine and this is natorious for happening. my check engine light also came on and so I had a diagnostics done which told me my #1 injector wasn't firing , car ran like **** as well. After putting in a new water pump and plugs,ect. and realized injector was good a friend told him we could have a blown head gasket. So just to see if this was the problem I went to buy a bottle of glassbeads and the auto parts guy told us to purchase a bottle of BARS STOP LEAK BLOCK SEALER NOT RADIATOR BUT BLOCK SEALER $31.99 . He followed the directions and we waited 24 hrs. before driving it. What ever the problem was has stopped my car runs like brand new and I am loving it again. no over heating no injector problem, runs great.......I hope this helps. I know its probly a temperary fix but its a fix and now we know what the problem was. SASSY

SOURCE: Hoses to cooling system keeps bursting

I agree with the questions asked by c17hydro, but also keep in mind that if the new coolant hoses are springing new leaks in the body of the hoses (not at the connecting points), this would be due to excessive PSI build-up in the hoses and you may have a much larger problem. After the car has sat and cooled overnight, start the car with the hood up. IF after 3-5 minutes of idling, the coolant hoses build up pressure immediately (hoses are very firm), this may be due to exhaust fumes entering the cooling system, which is an indication you have blown a head gasket or cracked the cylinder head. Your car will still run, but it's performance will be very poor and sluggish.

The oil alarm come on after a 10mn drive at slow down

Check for low oil level on engine dipstick. If not that, change the oil, it is getting too thick. If not that, there is a clog in the oil pump or the oil filter. Change the oil filter first.

Oil gauge goes to 80psi while I'm driving 70mph on highway, drops when I slow down. Why?

They are designed to change as the motor changes speed. If you have 80 lbs. of oil pressure than you have very good oil pressure in your engine. If it gets higher than 80, I would talk to service dept. at your local dealer.

Help me please.....

You must use 10W30 oil in the summer. On really hot days, when you are stopped and in drive, the oil pressure will drop to almost zero (according to the dash gauge).
If this is not happening under the above conditions, you need to place a shop gauge in the oil sensor sender port and test for proper pressure. If it is low (out of spec), you need to ensure the oil sump is not plugged in the crankcase. If it's not plugged, you need to replace the oil pump and fast!

The ABS issue is probably caused by the EBCTM module on the back of the ABS modulator, loose fuse, or bad connection to the module. Affects the cruise and PS as well.
