    Mechanic just replaced thermostat said car is over heating right away...Can it be anything other then the heads?

    Stephen Jul 17, 2013

    Yes it could be several things including the water pump or a blockage in the radiator. The problem is, once the engine overheats, the head gaskets get stretched and they won't go back into their original shape. So you could have a problem with the cooling system and also a leaking head gasket. Or the gasket could have failed and that caused the problem on the road. A mechanic can do tests to find out if the cooling liquid is flowing correctly thru the system, and if one or both of the head gaskets are leaking before the heads are removed. But the amount of damage can not be determined until the heads are pulled. I would get a second opinion since you have lost faith in this shop.

    Steve,he just started the truck up&was ready to drive..Said everything look good...Then out of no where the temp just shot up,with out warning lol...That's what happen to me when it first happen...I told him to do a compression test so thats the next step.

  • ALBERT Jul 18, 2013

    Also last week prior to car having this over heating issue...There was a winding noise that he said was either compressor,power steering pump or WATER PUMP...He did the stethoscope test&said he believed it to be the power steering pump...When his assistant said,he thought it was the WATER PUMP...Its kinda funny the car is now dealing with the hot issue right after that!And yes seen the hose he took off it had a lot of cracks&warpness to it...It definitely needed replacing reguardless.

    Just for the record, has anyone checked the gauge to see if it is accurate ? Is the engine really going over 250 degrees when the gauge spikes ?

  • ALBERT Jul 19, 2013

    Hey Stephen,No water on the dipstick,no grey smoke from tail...Coolant is stayin in&NOT LEAKING ANY WHERE"!...Range starts right up,then temp spikes after like 3 to 5 min...Felt top hose lot of pressure on it...Car won't start...Wait about 3 to 5 min CAR STARTS RIGHT UP LOL...I am telling my mechanic&one of the clients i fitness train that it is a"WATER PUMP"...He said his car spike like that twice different cars&it was a"BAD WATER PUMP"...My mechanic is lost on this one,he admitted he's baffled as well lol...I think the noise I heard in the engine department last week" A WINDING SOUND"has some connection with this...I youtube&all mechanics said that"WINDING SOUND"is a precurssor to the bearings going bad in the"WATER PUMP"...A couple days after that"WINDING SOUND"the car over heated on me on the highway...Bottom hose replaced,new thermostat put in...I read either WATER PUMP OR AIR LOCK???What's your call on this???All the mechanics ever wanna say is"HEADS FIRST"...My mechanic say's he's 90% sure its that!lol

  •  Stephen
    Stephen Jul 19, 2013

    As I said before, yes it could be a water pump. But that would not account for the no start. And it can have a leaking head gasket and putting pressure into the cooling system without any coolant getting into the engine. Yet.

  • ALBERT Jul 19, 2013

    Thanks Stephen for prompt response again...I guess,I am not VIP enough for any one else to have a solution lol!..So should i just go ahead and change the water pump?Its gotta be far less then heads repair!...Also do you know if&wher the BURP TUBE is located?My mechanic does not see it&neither do I? The forums mention a BURP tube...Is it not on this model i have?RANGE ROVER 2000 4.6 HSE!

    A major problem with owning a car or truck that is not a common brand is the lack of qualified mechanics to work on it. I owned a 97 Range Rover and with me being a mechanic it was still a high cost toy. A dead cell in a battery is not something a mechanic can cause. You can price the parts to do the compressor and check his numbers. You should get an itemized estimate anytime you are talking about service over $100. From any shop.

    As for the codes, a mechanic would write down the codes, clear them, then drive the truck and see if they come back. Then troubleshoot the ones that do using the factory procedure. Otherwise they could not guarantee the repair will fix the problem.

  • ALBERT Jul 25, 2013

    Thanks Steve,i was hoping you got back...Do you think that price is a bit out rageous...Also,should i just bite the bullet and take it to Land Rover...Atlease i know it will get done right...What could have caused the cutting off when it was getting hot?Before that my car was fine,the battery was good...How could 1 over heat cause ALL THOSE CODES...Also i ran into 6 people in the last day who just thru discussion said,DO NOT LEAVE MY TRUCK THERE!..Said they will just add things,fix it&then expect you to pay when you didn't ask for them to do it..Or already order the part!

  • ALBERT Jul 25, 2013

    One of the guys who comes to my fitness class said,they fixed something with out his permisssion&demanded payment...He had to literaly reach over the counter&grab his keys...They settle up but it got real ugly...Myy question how much for compression&head block test at the most?..That will 900$..300 for my mechanic putting on thermostat&hose...Now 600 just to diagnose&i still don't have it lol

  • ALBERT Jul 25, 2013

    Still don't have my Range back...Next time,straight to the dealer!

    The computer can shut down the engine if it goes above 250 degrees. A basic compression test is around $100, I don't know what they did for a block test. Generally a shop is supposed to charge diagnostic time by the hour, and not without having permission of the owner. IE- you give them the green light to do diagnostic work two or three hours at a time until they find the problem.

Not much we can do online about the mechanic. The hose probably blew when the engine overheated, so he would need to replace it to test the cooling system. And yes the thermostat would be tested or replaced before removing the heads.
Be sure and get a second opinion if his final diagnosis is a blown head gasket. He may be right, but better to be sure.

Testimonial: "I appreciate the prompt response Steve...I feel like my mechanic is just pushing the heads to be replaced...Why even order the thermostat in the first place if that's the only resolve your pushing...Not sure but this is the first time i didn't feel sincerity with him almost like he's just reaching and that bothers me...I Started truck right up...Looked at dip stick,oil look good,no water...Just oil on the stick...He did show me the hose it had a lot of worn cracks on it...Whats the percent success of doing new heads..He said,I am looking at around 12 to 1300 for whole job?Oh,and this is 2000 not a 2004 range rover...Hse 4.6 8 cylinder...102k miles"

My car temp gauge showed over heating at highway speed. Then upper rad hose blew. Pulled over and had car towed home. I have a Matco tools code reader. Computer doesn't show any codes. Why would that...


Using your tatco code reader, select current data (real-time data) and select engine coolant temp sensor (ECT). Run engine to operating temperature (A/C off). Monitor the temp reading - when the temp reaches approx 204 deg farenheit, the fans should kick on, after the temp drops to approx 198 deg farenheit, the fans should turn off. The fans are controled by the ECM (Engine Control Module). The ECM controls the cooling fan relays.

Overheating / Stem from water / coolent reservor


that did not sound like any fun. most likely your water pump has failed on you. you will want to replace both timing belt and rollers and tensioner. they most likely will have been soaked by coolant also the want to look at the coolant flange on the drivers side of the engine block. if it is leaking or not the burning smell is probably the oil leaking onto the exhuast manifold from a leaking v/c cover gasket.hope it helps good luck.

Heating problem


If you changed the thermostat yourself and have noted that the lower radiator hose is cooler than the upper radiator hose, you may have installed the thermostat incorrectly or have purchased a faulty thermostat. A lower radiator hose that does not get hot (or as hot as the upper radiator hose) is a direct indication of a faulty thermostat. Please vote for this solution if you found this to be helpful.
